    I have a Sony WEGA rear projection TV, model: KP-51WS520
    Purchased November 2004

    When I turn it on, no power and no sound.  The standby light initially flashes 10 times and then pauses for a couple of seconds and then flashes 9 times.  Then it stays in the 9 flash, pause, 9 flash, pause, infinity loop.

    Fuse??

    Thanks for any assistance.  I have really enjoyed this television!

    Welcome to Agoraquest!  Nine blinks means "Zero Crossing Detector".  The probable cause location listed is "D6116 or D6301 is open (G board)".

    Looking from the rear with the rear cover off, the G board is the first board form the left in the row of horizontally mounted boards at the bottom.  The chassis that the boards are mounted on my be withdrawn after removal of three screws that hold it in place.  The parts info is as follows:

    REF. NO.      PART NO.            DESCRIPTION         VALUES

    D6116         8-719-081-97      DIODE                   MMDL914T1
    D6301         6-500-567-21      DIODE                   10ERB20-TB5

    Apparently, these diodes are small enough that they do, in fact, act like fuses.  So you are definitely on the right track.

    Mr. Hill,

    You are indeed a Sony Pro.  Thanks a million for the info.  I will replace both of these.

    Thanks again.

    I couldn't find these diodes anywhere that are not on backorder for some reason until mid June.  Instead, which I wanted to avoid, I did find a G-Board Complete in-stock for $99.00 which I don't think is too much damage.  I love the television and want to keep it for awhile.  I've had my KP-51WS520 since August 2005.  Take care.  Pogi31

    Welcome to Agoraquest!  Replacing the G board should bring your set back to life.  Good luck!

    *There is piece of paper in the box with instructions to return the old G board for a refund.  Nothing of a refund was mentioned when I purchased the board? I don't want to pay another shipping charge, to find there is no refund.  Will they charge me, if I don't send the old one back?  Thanks!

    Welcome to Agoraquest!  I don't have the answer.  Why don't you call them and ask at 1-800-488-7669?

    Thank Google I found this message thread! My 22-month-old KP-51WS520 just started the nine blink problem two days ago. It's getting harder and harder to get it to turn on. I have the exact same 10 blink, pause, 9 blink, repeat problem. As luck would have it, I'm local to the Sony parts warehouse you linked to! Unfortunately, they don't let random people stop by to pick up parts, so I'll have to wait on the Kansas City post office to do its job. Fingers crossed... I'll let you know if the $60 G board works for me...

    Hey, great news! I just re-soldered the small D6116 on the bottom of the G board and it seemed to do the trick--the set powered right on. Since the replacement board is in the mail, I'm going to leave my TV on through football weekend just in case I was only lucky.

    So, for anybody else whose 9-blink problems are intermittent like mine, try adding some fresh solder to those diodes before you ditch the whole thing.

    Hey Jehill (Sony Pro)

    I have 6 SS-LA500ED, 1 SS-LAC505ED, and a SA WD200, my question is does anyone still sell the stands for the SS-LA500ED? Remember the nice aluminum stand with the ball socket end to mount these around waist high? I recently added a couch to my listening room and want to go stands now. I'm using Monster M1 cables to the front L&R, and ZR2's
    to the rest of my Sony speakers. Powered by my Denon POA and AVP 5000 Digital amp and pre-amp. Aren't these babies nice, I can't understand why more people didn't discover these little gems. I also add an additional powered subwoofer to my rig occasionaly a Energy eXL-S12.
    Do you have any tricks on best wiring to go thru the WD200 crossover?

    I have a ke 42xbr900 with a picture that is black and powers down within 10 seconds.  I get 9 red flashing lights (but not 10 at first).  I took it to a local repair shop and they told me I needed the "G" board.  I replaced the board, and $500 later, it still does the same thing.  Now the RY1001 relay flutters before shutting down and giving the 9 lights.

    Thanks for any assistance.  This is the best tv I've ever owned and would hate to loose it!

    Hello John,

    The model # for the whole package is KE-42XBR900.  The model # on the display is PDM-4200.  The model # on the media receiver is MBT-XBR900.  I hope that this is the information you need.

    Thank you for the quick response!

    Brian

    Thanks for the posting....  It was a great help.  I've ordered the G board but I've never done this type of replacement.  I haven't had the time to open the TV.  What is the diffculty of replaceing this part?  Is it plug-n-play?  Again thanks for the help there is a huge difference in the $60 part and the $450 that the Sony repair affilaite wants to come out and fix.

    Jehill,

    Thanks for sharing your knowledge with us. I'm also getting the 10 -9 repeating blinking lights.

    I however am so disgusted with Sony right now I'm not sure I'll buy another tv from them.

    I followed your link to purchase a new G board and filled out the order. The part number showed as Back ordered so I called in to find out when they might get more in or what the case would be only to find out what Phase III ment. I guess I have to send mine in for repair... should be fine, I was just hoping to have this resolved as quickly as posible.

    I've tried to find the diodes also and seems one has a new part number from sony but the other shows as out of stock. Does anyone know of any other sites that I can get either a complete new G board or the diodes?

    PS reason for not buying another sony has nothing to do with the Phase III or the fact the TV failed after such a short time... rather the rudeness of their customer service when I called to inquire about the parts. After a brief call where I found out what Phase III ment... the person sent me on my way and cancled my order. I'm glad I called back in to ask where I could read about "Phase III" because the second guy... while still extremly rude... noticed my order cancled and recreated it for me.

    So anyone else looking for this part be forwarned... on Sony's parts site.. if a part says Phase III *you are not going to receive a new part* they expect you to ship yours in for repair. This is not posted anywhere on their site... Phase III I'm told is an internal code used by sony.

    heh after all of this I just hope my problems stop with this board.

    Shao

    I am sorry to hear that your experience with Sony reps was not a pleasant one.  Its a matter of the luck of the draw.  You might have had a totally differenct experience with another rep.  Did you try Googling the manufacture part numbers that I listed in the "Values" column?  Usually they are available for a fraction of Sony's cost.

    Just chiming in with another success story! KP-51WS20 didn't turn on one day. Searched Google, came up with this thread, saved me 500 bucks in repairs! Re-soldered the D6116 and D6301 diodes and the thing fired right up! Thank You! Thank You! Thank You Jehill!

    Legdiian, do you mind doing a quick write up on how you re-solder the diodes? and where to buy these diodes? I have looked on the internet but seems like the G-board is no longer available. Anyone knows?

    Ok posting another successful story. I called several local repair shop as provided by Sony, two of them wanted $89 up front just to come look at my TV (lol, stupid). Another shop gave me an estimate based on the 9 blinks code, they told me it was the G-Board (blah blah blah, ok I knew it was the G-Board, now what?) then they said the part itself is only $50 something (ok so far so good). Then they told me the labor is about $350-$400 (left me speechless, all they have to do is unscrew the back panel, get the board out, and replace with the 2 screws and put the panel back in place. I am sure a 10 yr old can do all that but anyways, total quoted was $450-$500). So after ready this post, I called Sony Parts dept and ordered both Diode as listed by jehill (BTW, thanks a ton!! you are the man). Parts arrived few days later, I took apart the panel and got access to the G-Board, re-soldered just D6301 since its a bigger piece easier to solder...tried powering it on...and it fired right up! Didn't have to replace the smaller D6116 (lucky me). So anyways, thanks to jehill.

    Well, here's another person with the identical "9 flash" problem that became terminal today. It did this to me once before, but I hit the power button a few times and it came on, so I kind of wrote it up to being a transient glitch at the time.
    I was hoping to get away with just heating up the solder joints on the mentioned diodes to fix it, no luck though.
    Just a note: My "G" board doesn't seem to have the D6116 diode at all. In fact, quite a bit of the board, probably half,  is unpopulated. I guess it would be used for slightly different models.

    My "G" board looks like it has a BUNCH of cold joints on it, so next I tried looking around for a complete replacement. NOBODY has it anymore that I have found so far. I did find a place that will rebuild it (sony.nexttronicsparts.com), and I may go that route, but I'm going to take the board to work tomorrow where I have my de-soldering equipment and see if that D6301 diode is good or not. I might also take the cover off the relay on that board and see how it looks since I think i heard someone mention that it could be the culprit.
    www.ued.net claims to sell the D6301 Diode, but says it's backordered until 6/7/07. Hopefully I won't have to wait that long. I'll update when I have news.

    Ok, I pulled and tested the Diode in question. It measures infinite resistance one way, and about 400 Ohms the other. As I recall from Electronics class way back when, this is not good- It should be no resistance one way and infinite the other.
    Unless I discover otherwise, I'm going to go ahead and order a replacement diode. $4.00 plus shipping is a pretty small gamble.

    The forward resistance measured depends on the test circuit.  Did you use the lowest available resistance scale?  What was the scale?  It certainly won't hurt anything the replace the diode.

    Now UED says it's not going to be available until 6/11!!!

    DUH! I can order the diode from Sony. I just put the order in.

    I put the TV from our bedroom in the living room to tide us over until we get the big Sony fixed. It's one of those that has a DVD and VCR built in. Today my 2 year old boy reportedly put a cheese snack in the VCR tape slot. All functions promptly stopped working. This is not a good month for our television sets.
    I opened the set and found the offending fromage laying on the circuit board, probably shorting it out or otherwise changing electrical values in a way not conducive to proper operation. I didn't bother to measure it with my multimeter. Anyone know what the electrical resistance of mozzarella twisted with cheddar is?
    After a careful extraction, the set is working again, although it seems to favor French channels.

    Oh hi, I must've been typing while you were.
    Yeah I had the scale set on 2K, that was the lowest it would register at. Think it was bad?

    I have also the same 9 blink problem --Sony KP-46WT520 -resoldered the Diodes 3 months ago now it went bad again --and soldering does not work  second time around--will this G Board A1065549A work on this model too ?

    I doubt it.  I always measure forward resistance on a R X1 scale.  400 ohms on a 2K scale tells me that the ohmmeter isn't supplying enough current to cause the diode to conduct.

    Hmm, well my multimeter has a setting on it specifically for testing diodes, but even so, the new diode I got yesterday measured only 75 or so ohms different. I replaced it anyway, and although it's an affront to the scientific method, I also re-soldered any other diodes and checked out the relay.
    Popped the  board back on and knock on wood, the set's been working fine so far!

    Thanks for everyone's input.

    No.  The part number for the KP46WT520 G board is A-1054-157-A.  It appears that it and its replacement, part number 9-910-999-Y1, is no longer availavible.  You may check the part status here.

    I have found that the G Board is impossible to find for purchase.  I am going to try the re-soldering of the diodes, but cannot locate them. Does anyone have a service manual they can email me?  Or, help me in locating the diodes?

    Thanks.

    Guys, some of the information you requested is right here in this thread, the rest is in the site. I mentioned a place that will rebuild your board, and Sony sells the diodes. Someone even tells you where/which diodes to mess with, how to locate the board and what to do with it. You just have to look.

    If you need a service manual, you can download a lot of them for free at www.schematicsforfree.com. The one for the KP-46WT520 / KP-51WS520 / KP-57WS520 is on that site, here:

    Hi my name is Rex and was wondering if anybody can assist me with my Sony WEGA rear projection TV, model: KP-51WS520. The same problem exists with my television. ( 9 blinks..9 blinks) Can someone tell me what the problem is, what part I need, where I can get the part, how to repair it, and the tools that are needed. I am not an electrician so please keep the explanation simple. Thanks.

    I found your forum very interesting. I have had my Sony KP46WT520 for about 24 months and I too have the standby light flashing 9-times problem. I have ordered the diodes from the website that you posted jehill (thanks for the info). I am just hoping that these are the same diodes that I would need for my model as well b/c the model has been discontinued and no luck on a new GBoard.

    ok---People listen up I too had the problem (see below previous message)  I send the entire G-Board A-1054-157-A To TRI-STATEMODULELING ---WWW.TRISTATEMODULE.COM to rebuilt they sent it back within 10 days and popped it in and was blinded by the power --yes it powdered on and it only cost $ 39.95 PLUS $ 6.95 SHIPPING --WHAT LUCK


    DALLIEDOG








    I have also the same 9 blink problem --Sony KP-46WT520 -resoldered the Diodes 3 months ago now it went bad again --and soldering does not work  second time around--will this G Board A-1054-157-A work on this model too ?  Can anyone please help !

    jehill, Just want to say thanks. I recieved my parts from Sony luckily I only had to change the larger of the two diodes. I popped the board back in and the TV fired right up. The shop that Sony reffered me to was going to charge me $200 plus labor even though I had already told them what was wrong with the unit. I appreciate the info instead of $200 it only cost me $22...Thanks

    Yeah, it's nice to know that even in the year 2007, having basic soldering skills can save you a ton of money with modern appliances.

    I am amazed. You have saved me a ton of money. I soldered both diodes and the TV is working fine. I have the 57" variety. I can't thank you enough for the knowledge and this thread. It's people like you guys that keep consumers from getting ripped off all the time.

    The solder lasted for 10 days, 9 blinks started again. I replaced the 6301 diode and put the board back in and now I am getting 4 blinks. Any suggestions?

    my sony kp46wt520 turned off a few weeks ago, and showed 10 blinks.  Then a couple days later it just turned on.  Then it turned off again, this time flashing 5 times. Tried the unplug, turn back on, to no avail.  Still 5 flashes.  The 1 day, I held reset button on remote while hitting on switch, IT CAME ON !!  Decided to leave it on.  Turned off 3 days later.  Did same thing, with reset button, came on....lol . Again left tv on....lasted 3 days and turned off.  Now it does not respond to the resert and turn on trick and is flashing 5 times.  I'm out of work, and really miss my tv.  Is this common ? And is there a cheap fix or am I in trouble ?  Thanks, Bud

    hello guys newbie here I have a KP51WS520 WITH THE 10 LIGHTS 9 BLINK STANDBY LIGHTS CYCLE ON MY TV TOO.
    I TOOK THE G BOARD FROM THE BACK AND CHECK ALL THE DIODES AND THEY ALL R OK. THE ONLY PROBLEM WAS THAT THE TRANSFORMER ON T-6301 & T-6101 HAD NO READING.

    CAN I ORDER THAT PART? IS IT EASY TO DO B/C IM ELECTRICAL CHALLENGE?
    ANY HELP WOULD BE GREAT.

    Just chiming in to report that this fixed my KP-51WS520. AMAZING!! I was hoping it would work, but despite all the successful reports, I have to say that I was still a little skeptical. I ended up having to replace only the D6301. I ordered my parts directly from Sony at this link: http://servicesales.sel.sony.com/ecom/accessories/web/index.jsp. Just use the search on the right-hand side.


    I also noticed that there were no pictures posted by anyone of the actual G-board or the diodes that need to be replaced.


    Here is the G-board itself looking at the back of the TV:


    http://img47.imageshack.us/img47/8396/backev6.jpg


    And here is the D6301 diode, also looking from the same angle (it's in the middle-right of the G-board):

    Thanks to everyone who posted the solution and their success stories. Hope this helps.

    Okay this thread is wonderful, have the kp-46wt520 with the 9 blinking lights and I just ordered the diodes to start since i would rather not have to rebuild or replace the entire G board if i don't have to.  That said, it's been, well more years than i am willing to admit, since my high school electronics class!  Can someone give a basic breakdown of how to solder the things when i get em??  i do have an iron and remember some basic skills, but things like "for best results you should use xyz type solder", and "to remove the diode you are replacing, first...".  i know i am not the only one in the thread to have requested this, but haven't seen any responses...come on, all you who have done it successfully, helps us remedials out!!
    BTW-thanks to lukeinjax for the pics, i know those will help me!

    New to the site. I am hoping I can get some help from the folks here. I have a 2 yr old KV-36FS120. The standby light is flashing 9 times. My son couldn't get the TV to power on, unless he held the power button in until it came on. Now, it will not power on at all. Can anyone make a suggestion?? All help is appreciated. Thanks in advance.

    Got to your Inbox at the bottom of the left column and send me (jehill) a private mesage requesting the "KV27FS320, KV32FS120, KV32FS320, KV36FS120 and KV36FS320, 9 blinks" service bulletin and I will send it to you.  Be sure to include your email address!

    Gigi095 - To get the G-board out, of course, you will have to remove the cover from the back of the TV (self explanatory). There will be 3 or 4 connections (if I remember correctly) that you will have to detatch. Some of them have a clip mechanism (don't just yank on them). The locations should of these should be obvious. Just look for wires that attach to the board. There are also 2 screws (again, speaking from memory) that mount the G-board to the TV.

    Once you get the board out, use desoldering braid to remove the old solder so you can remove the diodes. Light-duty rosin-core solder should do the trick with a 15w soldering iron. (You can get everything you need at Radioshack for ~$20). Google "how to solder" for instructions on basic soldering.

    The whole process turned out to be easier than I expected. Hope this helps.

    No it isn't.  Perhaps you can get Tri-State to rebuild it.

    I have a Sony KDP-57WS550 purchased Dec 2004 and have the same problem as most of the folks here so I figured I'd try to resolder as a temp fix and order/install the D6116 and D6301 diodes as a permanent fix.  When I finally got the board that I think is the G board out (many wires, many screws, a couple clips, etc.) I can't find either of those two diodes.  I'm wondering if maybe my circuit board is different, but I'm definitely getting the 9 flashes.  The board I removed is marked Sony 1 689 180 21 and is definitely the power board.  Can someone help!?!?!  I really don't want to put everything back together or pay $400-500 to fix this thing if I can do it myself!
     
    Thanks!

    Just a quick story on my experience after reading through everyone's comments which lead me through this adventure...

    I have a KP-65WS510, for the last couple of weeks or so my TV has been making a loud surge noise through the speakers when I power off.

    This week, it shut off automatically and gave me the nine blinks in standby mode.  Called Sony...no luck with them, they suggested having a service tech look at it.

    Based on the comments of this forum, I pulled out the G-Board to check the diodes (I know not the same model that has been discussed, but it was a starting point).  Couldn't find diode D6116 or D6301, obviously different model.  Nothing looked out-of-place.

    I was able to download the service manual for KP-57WS500, what the heck...close enough!

    The 9-blink code for this model suggest an audio error:


    -+19V line is shorted (A,B Boards)


    -IC708 is faulty (A Board)


    -PS701 or PS702 is opened (A Board)


    As suggested in the manual, I cleared the error message using the remote control and went digging into the back of my TV again.


    Pulled the B Board out and wiggled IC708, PS701, and PS702.  Again, nothing really stood out.  Put everything back together, fired her back up and shut off the speakers to see if it would stay on for more than a minute.


    5 minutes later, we're good...turn the speakers back on & ....no sound!  Great, I must of broke something back there or forgot to replace a wire of something!

    Nope...just forgot to hook up the RCA cable under the DVI input...oops!

    Everything is working fine now, but I'm still getting that pop noise during power down, although it doesn't seem as loud.

    Sorry, went a little long, but that's most of it...THANKS FOR THIS FORUM!

    Just wanted to say this thread is great. I have the 57" rear projection model of this line that had the 9-blink code. Took the G board to the local repair shop and the guy told me I'd have to bring in the whole TV (yeah right). I used a multimeter to check diodes D6116 and D6301 on the G board and they checked out fine, so I re-soldered the connections and presto: working TV! 20 minutes of internet research and about 15 minutes worth of work saved who knows how much money. Thanks to everyone for the advice.

    This board is great!

    I desolder, and then resolder and it worked.

    For those of you who have resolder and it worked how long did it work for, and will you still send your G board out to be rework?

    Again thanks for the help.

    Replaced the diodes on 57", no joy.
    Any other suggestions other than sending the board back.

    I have a water damaged KDP-57wS655 that the two power boards seem fine by my multimeter but the A board is too damaged for repair. Does anyone have one they no longer need from a broken set?

    All is well again.   
    Tri-State repaired the board. Turnaround time was approx 10 working days.

    Thanks to members comments and experiences, a solution was found.

    KP51WS520 standby flashing 9 times. That was my problem but it turned out pretty good so far. My Sony was covered by a not so good warranty. Service Tech said that parts were unavailable from Sony and the warranty paid me out pro rated. I kept the Sony and searched the web and found this thread. I could not believe it but I touched up the solder joints of D6301 reinstalled the G board and I'm back to watching HD hockey!! So much for this Service Tech. Thanks everyone.

    Hello Jehill,
    Thanks a lot for your advice. I had the 9 blink issue with my 51" Wega TV, and as you said, the issue was with two diodes on the bottom of G-Board, but instead of replacing them, I've just did a reflow on the solder and guess what?.....IT WORKS!!!! I'm really happy because I love my TV. Anyone having this problem would like to try this first. Anyway, I'm ordering this diodes just in case.

    Mr. Jehill, as we say here in Mexico, "SeŮor, es usted muy chingon!!" which is something like "Sr, you are the Fu**ing Man".

    Thanks!

    My KP61V80 projection TV died last week. I opened it out and found smoke coming out of the G Board. I removed the G Board (with difficulty - since I couldnt remove the 2 red cables sticking out of the flyback, I actually broke the flyback off the board by mistake when yanking on one of the cables). I looked into the board and found C517 a blue capacitor with burn marks. As luck would have it Sony has the G Board (A1054-157-A) in stock although they are doublechecking  that the one they have will work on my TV.
    The question I have is: does this board come with a flyback transformer or do I need to de solder and re solder the one from my existing board ? I couldnt get a photo of the board and dont have a schematic. Also, does anyone have any suggestions how to disconnect the cables from the flyback. I also realized (danggit) that I didnt label the cables so probably have a hard time reconnecting since the jacks on the connectors are not labelled.

    Thanks for your help y'all. Appreciate any replies.

    Had to register and say a HUGE thanks ! I have a sony 57" rear projection HDTV, model KDP-57WS655.

    It started giving me the 9 blinks upon power up a week back and became increasingly difficult to turn on, today it finally stopped coming on.  

    Read through this entire thread, hit up Radio Shack and $18 later it works like a charm agian.

    If there are folks reading this and are hesitant, don't be, I was a total novice with sodering and after a little practice away from the board, stepped in did the deed.  You've got nothing to lose as I couldn't find a G board for this model of TV anywhere and PTS wanted about $120 to send it in to them for repair.

    THANK YOU ! ! !

    I had the same problem and after reading this board I think I accidentally came up with a workaround.  It seems that if you don't hit the display button in the diagnostic sequence - "Display, channel 5, volume down, power" - The TV turns on without the diagnostic menu in front of the picture.  So basically it's on (although the power light is off) and I can watch anything I like.  My only concern is whether I may be risking more severe damage to my set by forcing it to turn on with a faulty diode connection.

    - Never mind what I said before, I think I just got lucky that it turned on a couple of times.  So I went out and got a soldering iron and fixed it.  The thing works perfectly now.  Thanks.  This board is great

    Thanks for the info.  I replaced the G board on my KP-57WS520.  The TV now works great...again 

    One problem...noticed the new G board is missing the ground plug in the corner of the board.  It appears it was never soddered in duing the manufacturing process.  Should I return the board?

    Wanted to update folks, the temporary fix of resoldering held up for about a week it appears as the problem has come back unfortuantely.  I just ordered the replacement diodes from Sony's website and will replace them to see if it clears up the problem.  If not, I'll be sending the board off for repair to TriState.

    G-board success story!!

    I ordered the board from the sony parts site even though they were out of stock, I felt better getting it from them than taking a chance on a rebuilt. Ordered it on 7/4 and it arrived 7/16, 7 working days, not bad. Popped it in and after a few second pause (just to make me nervous) it fired right up!! Nice to have 51 inches of HD back after 3 weeks of 24" non-HD.

    Thanks to everyone who posted info in this thread!!

    Update : All right got the larger Diode from Sony as the smaller one was on back order.  Replaced it on 7/12 and so far there have been no more issues, TV turns on with no problems.  Crossing my fingers it stays that way as I love this TV !

    No, however any silcon diodes that you purchase will probalbly work, but you may have trouble installing them.  Get at least 400V rating to be on the safe side.

    Another success story...
    I have the KP-51WS520 and it took about 2 days from being difficult to turn on to being impossible to turn on. Stand-by light flashed 9 times. This forum directed me to the G-board which I couldn't find anywhere online and ultimately to the diodes. I bought two of both of the diodes in question from www.Partstore.com for a total of around $20.

    D6301
    http://www.partstore.com/Part/Sony/Sony/650056721/New.aspx


    D6116 (I didn't even replace this diode...)
    http://www.partstore.com/Part/Sony/Sony/871907443/New.aspx

    I know nothing about electricity so I took the board and the new diodes into work where I work with a bunch of electrical engineers. I had one of them test both diodes on the board and he said they tested fine. Because they tested fine we didn't do anything and assumed the problem was something else.

    When I got home I decided to go ahead and at least try replacing the larger one (D6301) myself. Despite my horrible (HORRIBLE) soldering job the TV came on just fine and has since. (Less than 1 day so far but I am hopeful!) I am afraid my poor soldering job may limit the life of this fix but thats why I bought two diodes. Next time I'll buy lunch for one of the EEs at work.

    Total fix < $10

    Thank you all!

    I have the same problem but can't get a new G board.  Is it safe to take out myself and send to sony?  How hard is it to replace the diodes myself?

    I have the same problem and can't find a new G Board. Sony says you have to ship it in for them to refurbish. Can I pull it out myself without harming anything else? Is it hard to replace the diodes myself and how do you put them on?

    Hello! New member.
    Just wanted to say that i have the Sony KP-51WS520 TV.
    I had the same problem as others. Power on, standby light blinks 10 times, then 9-pause-9 blinks continuously.
    I just wanted to tell my experience.
    I searched the web and came across this site.
    I removed the G board and checked the diodes with my diode testing digital VOM meter.
    They both checked good. (One is very small and located on the bottom of the board, the side of the board that has all the solder joints on it.)
    I really didnt want to change these diodes out, would rather order the whole board, but the Sony site says the board is no longer available.
    I read where some of you guys re soldered the diodes.
    I tried that, just applying the soldering iron to each solder joint on the two diodes until the solder slightly melted.
    I waited about 30 seconds after each heat, to allow the diode to cool.
    I put the board back in the TV and it worked!
    I would really like to get this board on order, just in case it goes out again. Does anyone know where I can buy this board?
    I want to say thanks to you  guys, this looks like a great source board!
    Especially thanks to jehill.

    BTW, while I had the back off, I gently wiped the projector lens with a optic wipe, made for lenses.
    What is the preferred way to clean these lenses?
    Also, I was afraid I would scratch the mirror, so I didnt try to clean it. Whats the best way to clean it?
    Thanks agan!

    We also own the Sony KP-51WS520 and it also took about 2 days from being difficult to turn on to being impossible to turn on. When powered on I get 10 flashes on Standby red LED light, then 3 second dark then 9 flashes then 3 seconds blank then 9 flashes etc forever

    Got to this forum and thread via google, read all 7 pages of others experiences. Many many thanks to the original poster, the responder, the pictures and all the responses .

    I removed the offending circuit board, heated up my soldering iron, melted and reset first one then the other side of the D6301 diode's wires. Other diode is too small for my fumble fingers to attempt repair. Reinstalled the board and et voila, TV works again     . Going to watch Iron Man movie this Sunday night and Presidential Debate next Tuesday. Happy camper.

    If I have any more problems I will update on this forum.

    Worked for 13 days, today Oct 18, 2008 it's dead again . . .

    Okay, I've read this entire thread and I'm embarrassed to admit that I don't think I will be able to repair my television using any soldering techniques.  I have the 51WS520 and a few days ago, I started getting the nine blinks.  Because of hurricane Ike and the six-day power outage we experienced, I figured this was the cause.  But now reading all this, I'm upset to find out that it's a common problem with this particular television.  I've always liked my tv and am not ready to replace it yet.  Can somebody please tell me where I might be able to buy a new board to replace the existing one?  I may not have any soldering skills, but I can disconnect wires and take out screws.  

    Thanks in advance for your help!

    Thanks John and thanks for your original repair. Day two since "repair" and still working fine. Forgot to mention that the original diode's solder on back of the card looked perfect, nothing wrong, luckily I re-soldered and worked!

    Suzie, I just fixed mine (at least for 4 days now) and it was luckily for me simple, quick melt and solidify the solder. If you don't feel comfortable try asking a neighbor. If you read through the whole thread the best option I thought for replacement board was contacting WWW.TRISTATEMODULE.COM.

    I'm in Grand Lakes in Katy, West Houston where are you?

    Ok, my TV just went out again.
    The same 10 blinks- pause-9 blinks-pause- 9 blinks
    I could turn on TV by pressing Display- 5 - Volume down - power on the remote.
    Only problem with this (besides being very annoying to turn on this way), is that the self diagnostics screen stays up all the time.

    I removed the board and resoldered the  D3601 diode again. I didnt touch the very small D6116 diode this time.

    Plugged board back in and it's working for now.
    First fix lasted 10 days.
    I think I really need to get a replacement board. It's a rain pain removing the 13 screws that hold the back on, and I dont know how many more removals the screw holes can handle until they no longer grip the screw.

    OK so after my first melt and re-freeze the solder tack points that worked and then failed at 13 days, I just re-soldered again and again it's working, but like skenny, probably not for long.

    Skenny, jlsrpierce ;

    I had the exact same exxperience as you guys did.  Replacing that larger diode has kept the problem away for months so far and it was really easy to do.  I'd suggest sending Sony $6 for the diode as I wasn't able to track down a new G-board anywhere.

    Much appreciate advice, I was going to start phoning around for new G-Board, have as advised just ordered from online Sony Parts Store one new Item # = 650056721, Description = DIODE 10ERB20-TB5, for $3.15 plus tx and 1 week shipping for USD10.36.

    Found this info on easy way to replace diode without Solder Wick near bottom of page:
    http://www3.telus.net/chemelec/Soldering/Soldering.htm

    Will let you know how works out . . .

    No worries.  Check youtube as well there are some videos showing how to solder.  It was really straight forward, just make sure you note how the diode is now as I believe there is a positive and negative side to it but I made sure to replace the new one exactly how the old one was set and it fired right up and hasn't had a pause since.

    Cheers.

    Thanks Tmaz for the advice about the diode.
    My TV went out again. 9 days this time.
    I heated the solder a little hotter this time, because I was thinking that maybe I was afraid I would fry the diode before, so I might have been too conservative on the heat.
    The TV is working again, but Im going to go ahead and order the diode.
    This sucks having to take a good 30 minutes to do a temp fix.
    Hopefully the new diode will fix everything. Im getting ready to go new tv shopping if it doesnt.

    Thanks for the link jlsrpierce, I am going to check that out.

    Update: My problem has re-appeared, but the TV only fails to come on sometimes. I turn it off and on a few times and it works.
    I ordered a new diode form Sony, when I get a little free time I plan to change it out.
    Hopefully this will solve the problem from now on.

    Today I could not get the TV to come on at all.
    I swapped out the D6301 diode with the new one.
    TV is working for now.
    I will post here again if it messes up.
    I guess I just dont understand why this diode is acting this way. The one I removed checks right on my DVM diode checker. Forward voltage drop is about .468, which may be a little low, but I wouldnt think it would be that much of a difference.
    Looks like if it was just a loose connection because of a bad solder joint, the first fix would have been permanent.
    Could it be a loose joint somewhere else? Maybe removing the board just jars the loose joint?

    I noticed once when it wouldnt come on, I jarred the cabinet a little, next time it came on. Could have been a coincidence, or it could have jarred the loose connection.

    Anyway, I appreciate the help of this board. The info was great, and probably has saved me a couple hundred dollars in service calls aready.

    I have a KP-57WS520.  No video.  Upon turning on, the red light flashes 5 times (sometimes 6 times).  I am fairly mechanically adept and really like the TV (I've had it for 3 years).  In fact, I'm a big fan of Sony products in general.  Any advice?  Thanks in advance.

    See my posts above, got the blank screen & 9 flashes then 3 seconds no flash, repeat. Melted and reset the large diode, worked fine . . . failed again after 2 weeks, ordered $6 part from Sony (took 1 week to arrive), melted and re-froze solder on exisiting part, worked fine . . . failed again after 3 weeks, replaced the diode the right way around last night (made a mess of job), works fine with new diode (darn, can't justify new TV) . . . will update if fails again, fingers crossed.

    Update @ Dec 24, 2008, TV with brand new diode still working fine!

    To wrrii, most of us have initially 10 then repeat 9 flashing lights, your's could be the same problem? Worth a try of removing the board and melting and letting solder reset and reinstalling board, just in case that (temporarily) fixes the problem, or not in which case you may have to phone Sony, or buy a new TV (new ones sure are getting cheaper . . . 6 more months into this recession and they will be really cheap!). Good luck.

    Update @ Jan 19, 2010, TV with brand new diode still working fine!

    It is normal for the red standby light to flash when you turn the set on.  Error codes are repeative, i.e. n flashes, pause, n flashes, etc.  These are the error codes that jlsrpierce is referring to.

    Hi all...I am so glad that I found this site.  My KP-51WS520 just started with the 9 blink problem.  The TV will turn on after hitting the power button repeatedly but it looks like I need to replace the 2 diodes mentioned here.  I have read that not everyone is replacing the smaller 6116 and I saw that it might be under a three prong transistor (saw that in a different thread).  I don't have access to the TV right now to check it out, but what would I need to do to get access to the 6116...do I need to do something special to remove the transistor first?  I'll post back once I receive the parts from Sony and if it works or not.

    Welcome to Agoraquest!  You need to remove the G board in order to replace the diodes.  There is plenty of information on the subject in this thread.  Please take the time to revie it.

    Thanks for the reply!  I've read over the thread a few times...I should have been more clear.  I know I'll have to remove the G board, but there was a post in another thread that the smaller 6116 diode might be under a three prong transistor and was wondering if that is true and if that needs to be removed as well (didn't see that answered here).  Thanks again and hopefully this will fix my problem!

    Yes, it is true.  Th 3 prong transistor and D6301 are mounted on the top of the board while D6116 is mounted on the bottom of the board.  D6116 is very small and is surface mounted, meaning that it is soldered directly to to foil pads on the circuit board.

    Just a quick update.
    Its been nearly a month now since I replaced the diode.
    Still working great.
    I only replaced the larger D6301 diode.
    You may want to try replacing this one first, since it looks to me like the smaller diode will be much harder to replace, because it is so small.

      Doh!

    I got the D6301 diode out, was distracted for a bit with the kids, and now I don't rememder the way it should go back in!  I'm sure it matters, so does the red stripe on the diode face in toward the board or to the outside of the board?  

    Thanks in advance for helping me out of a jam!!

    On mine the red stripe is facing in toward the board.  I'm fixing my today too.

    Didyou or anyone else have problems getting the ground plug off the Gboard?  I read in this thread or others that some people did too.  It'sthe black cable with the yellow rubber end that plugs in on the bottomright side of the board as you open up the tv.  I've tried to get itout but I can't.  I went ahead and unplugged it from where itterminates (slid right out!) and will just go with that.  

    Forthe smaller diode, now that I have the board out, do I need to removethe 3 prong transistor to mount it??  I'm not seeing why I would needto.  Thanks!

    Thanks Bcuz.

    I also had problems with that plug.  There looks to be a small tab that needs to be pushed in to get it off.  Its under the yellow boot, but if you pinch the plug pretty tightly in the center it will come off.

    Good luck with yours, I've got my fingers crossed.

    Well I replaced the 6301 diode, but the metal tab on the antenna ground plug snapped off with all the moving of the board. After it snapped off, I still had a heck of a time pushing in the tab to release it from the cable.

    So now I'm figuring I need that 3 prong tab that is soldered on the G board that the cable with the yellow ends plugs into on the board. I believe it's CN6004 and the manual says it's part 169591511. Sony's site calls it a "tab (contact)". Could anyone confirm that this is what I'd need? The cable itself is still intact.

    Is this antenna ground cable needed to at least turn on and test if the new diode worked? Just wondering what exactly the antenna ground does if I am not using cable from an antenna but from the cable company. I could be totally off in my thoughts on that, I only wish I knew as much as most of the members here!!

    Well, I'm heartbroken.  After reading all of these posts and hearing of everyone else's luck, I changed out both the D6116 and D6301 diodes.  Try to power it up, same as before.  Hear the "click", get some sound, shuts itself off, blinks either 5, 9, or 10 times.  So I think maybe I've messed something up.  Good thing I ordered 2 of each diode, right?  Pull the board again, put new diodes on, extremely super carefully this time (not that I wasn't careful last time, just more careful this time).  Go to power it on...NOTHING!  No "click" no sound, just 9 or 10 blinks.  I could just about cry right now.  I guess it's time to send the board off to see if it can be tested/rebuilt.  The way my luck is going though, that will just be more money down the drain.  Thanks to all those who have posted in this thread, at least it made it so I could give it a shot on my own.

    TheNak,
    When my TV wouldnt come on, I couldnt hear the click.
    Just 10 blinks, pause, 9 blinks, pause , and so on.
    You may have had a different problem at first.
    But now that you dont hear the click, looks like the problem I had.
    I would double check the plugs on the board, if they look ok, then replace the diodes again, and make sure you have correct polarity on them.
    Maybe this will get you back to the original problem, then you can ask the experts on here about that.
    Good luck..

    Read back through these posts, I think someone said you could leave the ground wire disconnected.

    This site is awesome as I am having the same 9 blinking light problem.

    I went to take out the G board and I am having difficulty disconnecting one cable.  It is a black cable located in the front of the board next to the power supply.  It has a clear plastic tube where the cable attaches to the board.  Anyone know how to disconnect that cable and what it is?

    Thanks!


    Look VERY carefully, it has a small hook on the metal part... release it with a paper clip or something small. Good luck!

    Sony KP-51WS20
    I have been through the whole gambet on this one. I also had the 10/9 flashes and  as luck would have it I found this great site.
    Long story short, I tried to find a new G board that everyone says will fix the problem. I tried to find the board and thru all of the contacts listed on this site and I found out the board has been discontinued by Sony. I did find out that Sony (phone number 800 488 7669) will repair the board for $66 but will have to be without my TV while it is shipped back and forth and repaired.  Not sure how long the will take.
    The good new is I resoldered the diode and to my pleasent suprise it worked reat! I'm not sure how long it will last but I have my fingers crossed.
    I hope this will save someone some time.
    Good luck.

    Excellent Site!  I have the KDP57WS665.  I started getting the 10 blinks on power up and 9 blinks thereafter.  Found this site, read through the entire post, and got a little hope restored

    I went ahead and ordered the two diodes, D6116 and D6301.  Meanwhile, I figured while I wait for the diodes to arrive I could try to remove the old ones and solder them back on.  I didnít think this was going to work but it did!  When I put the board back in and hit the power there was my beautiful picture.

    Thanks for all of the info on this board!  You saved me a ton of money.

    Hi Everyone:

    The information on this board looks so helpful.  I am having the same issue with my KP46.  I ordered the two replacement diodes and will soon be attempting "the operation".  I did an initial assessment of the situation and am having difficulty getting the 4th connector off the G Board, but, after reading what others have said, I am going to try again.

    My issue, though, is that I can't seem to find the small diode on the board.  I found the number, but there does not appear to be anything in that place.  Otherwise, I would just replace the new part the same way.  Does anyone have a picture of what it should look like when it goes on?  (I know this is a stupid question, but is it possible it came off the board entirely somehow?)

    The diode you are looking for is on the foil side of the circuit board.  Its a small rectangular surface mounted chip.

    Well, I did it.  ...but, of course, taking out the board, I broke the wires on the 4th connector.  I decided to just try putting on the new 6301 anyway and that went as smoothly as it possibly could.  I put the board back in and just pushed the connector in as well as I could.  I pushed "power" and amazingly, the tv fired up like the day I bought it!  It might be a miracle and it has only been 2 days, so not sure if this is a permanent fix or what.

    While I'm on this though, can the little part on the connector I broke be ordered if something does happen?  I see how it would be very easy to replace.  The problem was that I broke the wires off right in the board (the worst possible spot) so they can't be soldered.  So far so good anyway.

    Just want to thank everyone on this board, but Jehill, in particular! If it wasn't for this board, I would have been shelling out for a new tv right about now.

    Just a quick update.
    My TV is still doing great after replacing the larger diode.
    But I have noticed lately that my screen settings are not being saved.
    It always goes back to Zoom when I power up.
    Is there a memory battery, similar to a PC CMOS, in this tv?
    Thanks, this is a great site.

    All important settings are store in NVR (Non-Volatile RAM), eliminating the need for a battery or huge capacitor to maintain the voltage.  Also, as long as the set is plugged in, the Standby +5VDC power supply is available.

    jehill, I have the 10/9 blinking light problem. I resoldered the diodes and it worked for about a week. I resoldered again and it lasted for a few days. I have done this a few more times and it only works for a few days. I tried to buy the a105415a g board but it is discontinued. My only option is to send it to Sony in Pa. but will take 3 weeks plus shipping time. Is their any other place I could purchase this board?
    Thanks for your help.

    Can any 1 Help. I have the same problem on Sony KP-51WS520. I hit the power button, timer blinks a couple times & powers off. I have 2 tv exactly the same model. I took out the G-Board from the TV that does work & placed it on the TV that dosnt work & it does the exact samething. So i guess its not the Diodes or the G-Board. Any other clues i can try ??

    I received a sonyKP-61V85 with the g board missing. Where can I get a A new g board at a decent price. Are there other units that are compatible if I found another unit that had other issues maybe a good board.

    Try http://www.tristatemodule.com/ for parts, they should have a G board at a good price. Also, if you guys need the service manual, just upgrade to premium membership and I can send that to you.

    I have a question regarding my Sony KP-51SW520 TV.  I'm having the same issue as most of the people (standby light flashing 9 times).  I've ordered the two diodes you guys mentioned.  I'm now at the point where I need to install them.  I've unscrewed everything and I should now remove the board.    How the hell to I remove the yellow connector without breaking everything?  See pic.

    Alright, I end up being able to remove it from the other end!  ;-)


    I've notice, by reading this forum, that people donít tend to do post pictures and since I like to visualize things, I thought it would not be a bad idea to do so, for ones that are like me.  Ok, perhaps you guys are expert and don't need picutres, but Iím not!

    Question!  Iíve been able to figure out where to put the diode D6301 (10ERB20-TB5), but can anyone tell me where the other one, D6116 (BAS316-115), goes on the board?

    Thank you

    Never mind guys, I figure it out. 

    D6116 is not a big black plastic square; it is in fact a tiny cylinder within a shell, from which the diode need to be remove. I hope my inexperience will help people.

    Cheers.

    Guys

    I have the same problem, my diodes look good(voltage still going through)

    I can't get the G board off though because of the Yellow cable Senna8 highlighted in his picture.. Can anyone advise the easiest way to get it off.

    Thanks

    Hi Senna:

    My recommendation regarding taking the yellow cord off would be to carefully cut or tear the yellow rubber off the cord.  When that is off, you will see how easy it is too take off (just squeeze the tiny clip).  I made the mistake of trying to do it with the yellow rubber still on and I ended up breaking the whole thing off.   Fortunately, I was able to repair the connection, but I still regret not doing it the way I suggest to you.

    A big thank you to everyone who posted tips on repairing this problem. Thanks specially to those who posted pictures.

    I was getting 9 blinks on my Sony Rear Projection KP-51WS520 purchased in 2004. After going through all the messages in this thread, I placed an order for the two diodes. Last night, I opened up the rear panel and resoldered the D6301 diode. The TV fired right back up. I am guessing this will fail after a week or so. The new diodes should arrive by then. Will keep you guys posted on how it goes.

    By the way, I did not disconnect the yellow connector/black wire from the board for fear of breaking it. Instead, I just pulled it far enough out to get enough room to solder.

    I have a KV-27FS320 with the 9 blink problem. 9 blinks is not a valid error code in the service manual but it does show up on the TV diagnostics menu and shown as ZCD error like most other televisions. This model however does not have a "G" board or the D6116/D6301 diodes. I see a service bulletin referenced here that addresses this issue for my set. Can anyone send it to me?


    Thanks,

    I had to register so I could let you know that this site was the most helpful, even 3 years after the original post!  I was, obviously, having the same problem.  I read all the information in this thread, copied & printed some of the repair information and had my ex-boyfriend re-solder one of the diodes last night.  Just like magic...the TV turned on, just in time for my mom to watch the new Monk episode that she had been wanting to watch!  It was amazing.  He didn't think it would work.  He said...I don't see how just re-soldering this tiny little piece would change anything, but I'll do it.  I told him he should add TV repairman to his resume now, lol!  

    I realize this may be a temporary fix, so I still want to order parts to have on hand just in case, but the links I tried in this forum did not work.  Any suggestions as to where I might find the parts available in 2009?

    Thank you so much for not only having the knowledge to fix the TV without spending $100 to have a technician come out and tell me what the problem is when I already know what the problem is, then God only knows how much more to actually fix it, but also for SHARING that knowledge with anyone who is savvy enough to check the internet before shelling out hundreds on dollars on TV repair!  I, personally, am very grateful that people like you exist.  I am a single mom with a 20 month old, who works full time and live with & help my mom, and TV repair or purchase of a new TV are NOT in my budget!  

    Thank you, thank you, thank you!

    Wow, I can believe it!! my family have a KV-27FS320 since Nov 2004 but it does not work since Aug 2008 (9 blink problem), I sent it to Sony (in order to fix it) but they want to charge me 450 u$s, my problem is that this Tv is located in South America and they need to request the part (complete board) to Sony USA + shipping + customs + service charge + 2~3 months etc etc= 450u$s

    I will be there in 6 weeks, if I get the part I will fix it

    I too have a kp 51ws520 and have the 9 blinks problem. Is there any info up to date on where I can find a G board? I have searched and searched but no luck. I would hate to have to buy a new TV at the moment

    The kp51ws520 G board part number is A-1054-157-A.  Although the part is no longer available from Sony, you may be able to get a re-built board or have your board re-built.  I would check out www.tristatemodule.com.

    I also have the 9blinks going on but I found a place that sell the g-board for the kp-51ws520. It's $164.00 and shipped to my door was $195. The lady at tri state said they could rebuild it for $60 but didn't know how long it would take. I want to say thank you for all the posts on this particular tv and now I just need to find a service manual (FREE) to download with the specs of the boards.

    Hey Guys I have the KP-51WS520 and it's starting to act all funny on me, I purchased this Television back in 2004 and it has been great but now the standby button is starting to blink 9 times slow, 11, 5 times fast. It really varies but nevertheless after playing with the power button a few times the Television fires on and it's like nothing happened. This has been happening steady for 3 weeks i say, From what I read from the previous Posts is that people are not getting any power or sound or the TV just simply does not come on. Mine always comes on after a few clicks of the power button but it is so annoying does this mean that my TV is on the Brink or failure completely? I looked online for those diodes and I came across the website and was wondering if I should order these and solder them which I have no experience in. I guess I need a Soldering kit from Radio Shack or something and melt the parts carefully?  Anyways here is the website can someone see if it's legit? Is this too cheap?http://www.nexttronics.com/catalog/sony/6/650056721.htm and
    http://www.nexttronics.com/catalog/sony/8/871907443.htmthey have both diodes with shipping at a cheap $22.00, So i guess if I order these and solder them My tv should be fine? just wanted to get an opinon because like I said My TV works fine after I play with the power button but it is very annoying to repetitive.

    thank you all and please let me know what you think I should do and in the meantime I'm gonna go to Best Buy and take a look at their TV prices!

    Ther is a relay on the G board, but I have no way of verifying that its the relay that you hear.  If you closely inspect the board, you should be able to find "G" somewhere, usually alone one of the edges.

    11/22/10 I own a Sony KP51WS520 HDTV Monitor and experienced the 10 standby blink problem. After reading this entire post, I called Sony Parts (800-488-7669) and ordered the infamous G Board D6301 diode part#650056721 (10ERB20-TB5). $6.72 w/ shipping. I did not mess with the recommended D6116 diode. Took my chances that it was only the D6301 that was bad. Recieved part in 1 week and replaced on the board. TV now works fine!
    THANK YOU FOR SAVING THE TV and saving me the estimated $750.00 repair bill.
    In the spirit of Pass it Along, here's a few tips for any novice that is concerned with tackling this issue themselves - it's easy:
    1. I have never soldered. Go to radio shack and buy a 15watt (small) pencil tip soldering iron, some solder, and solder wick (copper braid wire).
    2. In removing the G Board - 1st mark all the plug in type wire connectors on 1 side with a color majic marker. This will prevent you from wondering when you go to reconnect which side is the 'right' side to line up with the base. Mine unplugged without any issues except for the black one at the right front of the board when looking at the tv from the back side. Some folks call this the ground line, but I could not get it to unplug without what I thought would be enough force to break it - so, I simply twisted the board out leaving this connection in place. Had to lay on the floor to do the solder removal on the back of the board with the solder wick, and then also laying down, resoldered the diode back in place after removing the bad one using a set of needle nose pliers as the diode puller. The new diode comes with long lead wires and they are already bent in the proper places to align with the holes in the board, so simply grab the new diode with the pliers gently and line up the 2 leads to the holes in the board. The key thing to remember is which side the red stripe on the diode goes...note that before removing the old one. On my set the red stripe was on my left side when looking at the board from the back of the tv. When you have inserted the new diode, leave the leads their original length. Solder them 1st, then clip them off at the new solder joint with a pair of snips.
    It takes a while for the old solder to melt. Lay the solder wick braid on top of the old joints onthe back side of the board and place the iron tip on top of the braid right over the old joint. Within some seconds, 10 -20 seconds, the heat will finally penetrate the braid and melt the old joint. That old solder is sucked into the braid amazingly fast and without needing to do it twice.
    When resoldering the new leads, just remember to touch the board joint with the soldering iron tip and then touch your solder to the joint - doesn't take much for the solder to melt and weep around the lead - use as little as possible - less is good in soldering.
    Hope this helps.

    It was a great idea to include photos!  D6116 is on the foil side (bottom) of the circuit board near the bottom right corner of the transformer in the picture (T6301) viewed from the top.  It is surface mounted.

I order the $4.00 + shipping diode and replaced it and the tv works great!!!!

    I bought a sony kp-51ws520 back in 2004.  It comes on and goes off giving me a blink code 10 and then pauses and blinks again 10 times.  Does anyone have any answers?

    This (replacing diode 6301) worked great on my kp-57ws520 from 2004. I only learned to solder last week in preparation for this job and it went off w/o issue. VERY HAPPY I didn't have to spend hundreds on repair or a new TV.

    Thank you for all your help!

    I am not really as good with electronics as I am with cars but getting to the problem. I bought the Sony KP-51WS20 in 2004. The T.V has been working great up until this year. My neighbour has the same T.V and theirs is still working. I was playing Call of Duty on my Xbox when the picture went out. I have no Picture but still have Sound. I called in a repairman for $55 who looked at the problem and decided it needed a Deflection PCB. This repairman got rather angry when I mentioned the G Board or Diodes so I got my money back and hired another. The other repairman currently took $84 dollars and said the will either give the money back or discount from the price of the Deflection PCB. My TV also has the same flashing problems sometimes 5 or 10.

    Please Help.

    I just wanted to say that I removed the G board and re-soldered D6116 and D6103 (using a 15 watt soldering iron), and the TV now works fine. By resoldering I mean, I actually only reheated each solder joint with the clean tip of the iron, I did not add any extra solder. I also cleaned up the inside of the TV as there was a lot of dust on all of the boards and lenses etc. I also took pictures of the G board before I started just in case I needed to reference it when I re-installed. So, problem solved and money saved...THANKS for the great tips/info!

    The diode part number for D6116 seems to be MMDL914T1, which is not available based on my research. At least D6301 seems to be available from partstore.com.

    Any ideas where to get the part of D6116 (or equivalent diode)?

    Thanks.

    When I asked you if you had located the parts, I meant have you physically located them on the G board?  You should be able to come up with links yourself by Googling 10ERB20-TB6 for D6301 and MMDL914T1 for D6116.  If you can't locate the items at the sites, call the toll free number for assistance.

    I Googleed MMDL914T1 and found several sources of that part.  Its surface mounted.  Have you located the chip?  What is the complete model number of your set?

    Thanks for the quick response. My TV model number is KP-57WS520. I am looking for parts corresponding to D6116 and D6301 on the G-Board of course. I couldn't find the equivalents online. I will appreciate if you give me a few links.

    Many Thanks.

    I seem to be having a lot of trouble trying to find the diode D6116.

    I have searched many of the site listed in previous threads and it seems the part has been discontinued. I have also searched many of the suggested substitute parts.

    Any advice?

    Have you tried re-soldering the two diodes?  Quite often that is all that it takes.

    Hmmm. I will get my brother-in-law in to look at it. Guess it can't hurt trying since it was a free television.

    Very helpful thread. My KP-51WS520 crapped out this past weekend (9 blinks on standby). I was going to scrap it and join everyone in 2012 and get a flat panel.  Figure I had nothing to lose and I found this information.  

    I located diode D6301 from the pictures provided and just resoldered.  Fired up this CRT and it was good as new!  My electronic skills consist of a semester of  electronics back in high school over 20 years ago......

    DIY fixes are the best!  Saved me from buying a new TV.

    Welcome to Agoraquest!  For the KP51WS520, 3 blinks, pause, 3 blinks, etc. means "+B Overvoltage (OVP)" and the probable cause location listed is "IC6503 is faulty (D board)".

    This is the starting point for a qualified service technician.

    My Sony KP51WS520 had the 10 blinks and I change the D board. Unfortunately, D board are not available anymore, except thru exchange at Valley Service in 2810 West Valley Blvd., Alhambra, California; They repaired the D Board for me when I brought it in the morning and I pick it up in the afternoon. After putting the D board back on my TV it worked perfectly. Thakn you for your help and saved my hundreds of $$$$ in repair.

    I can post the picture of the D Board for others to see  but don't know how. Can you help  me post the picture.

    Thank you. 07.16.13
