Hi I am in the process of trying to repair this tv, it had no thermal fuse and a badly blown Lamp and the unit was packed with dust, the fan above the lamp is so caked in dust it has set solid, I want to remove it, I have got so far but i would like some help getting further, has anyone got any pics or information that could help me get right into the guts of the block as well as getting out the fan for cleaning, any help would be much appreciated.
I am also having real problems getting a thermal fuse for this model Sony say they dont recognize part number 1-910-023-93 despite me getting one from them a year ago for my own set, i have tried a couple of part sites recommended here but they wont post out of the US, have tried E-bay again any help sourcing would be a great help I am In New Zealand.
I have an old bulb that i replaced early when my optical block was replaced so if i can give it a good clean fit the fuse and Bulb i will be able to see where the condition of the set stands from there Many thanks for any information in advance, Phil NZ
Hi Claudio,Sony United States will only post within the U.S Sony NZ have not got a thermal fuse with that part number, and cant find anything close!! the tv is in bits i have been cleaning the fans etc, before i stripped it it was just flashing green about 20 times then nothing no red lights, I thought it might be because there was no thrmal fuse inside previous owner had taken it out because it was sparking, and the lamp was blown. Would i be able to do diagnostic without the fuse,lamp I have a lamp just got to get my hands on a fuse spent hours searching will carry on looking Cheers Phil.
Just an update well i went straight into the optical block i disconected the three ribbonns for the lenses which was a terrible move on my part they are imposible to get back in,and the three push down connectors all snapped, if i had removed all the screws i could have slid the whole lot out through the front. Since then i have brought two more for $150 about 75 US, both were thick with dust and the fans pretty useless as they were solid with muck. I spent the whole day cleaning the inside,fans,everything,fitted the new type thermal fuse which is now plinth mounted under the block and hey presto perfect, which i gave to my son and his partner, the second set has the dreaded blue spots, blew some air through and cleaned what i could without too much removing lenses and relfectors etc but it made no difference,yet to the naked eye they look prettyn good and not damaged. Have now got my eye on a kfwe50 which is defunked had a bit of fun rooting around inside them and got a bargain for my son, it is very hard to find optical blocks at the moment so i will sit on the blue spotted one for a while, whilst i have gutted my first attempt for spare parts. If anyone has recovered a block with the blue blob issue i would be intereted as to how/however i realize that it probably is not doable, Regards Phil.

There is a company called tri state module who sell refurbished optical blocks. Not sure if they ship international but it's worth a try. http://www.tristatemodule.com/ Let them know that you found them through Agoraquest. They have heard of our site. Maybe it will help with them shipping it to you. But recovering from the blue blob is possible. I have seen a couple of threads on it.
Hi claudio do you think you could possibly point me in the right direction of the threads on the blue blob/stars i would like to give it a go, and i was stunned yesterday when the only supplier in New Zealand refused to even give me a price on an optical block let alone supply me with one, it seems for those in New Zealand who have had the indignation of buying a Wega, and who have given,or sold at a song their sets if they want a repair must go soley through a Sony acredited agent at their own cost, can you believe the bare faced cheek of it, they refuse the person any chance of fitting the block for themselves, and of course no certified agent will supply the block at cost when they are losing out on the work!! They even told me that a block from the US would probably not be compatible!! Thank you for the link to Tristate. Phil
Well I found the thread and had the guts out of the light engine,polished and cleaned every lens in sight swapped the lenses nearest the lamp with some which came out my cannibalised tv and wham bam no change lol, great picture with a dvd just lots of annoying little blue spots, sometimes you cant even see them, what next!! cleaning the lenses and mirrors etc with alcohol will the lenses tolerate this!! or leave out each lense one by one, very very time consuming, however i am now super fast at dissmantling and re assembly. Went on the Tristate site they had no light engines in stock and Kiwi dollars have to be over doubled to reach the US dollar, no joy here a kit is over 1,500 NZ$ and even if i want one they will not supply as I am not a engineer etc,still the weather has been terrible so I have had great fun trying, even if a bit frustrating.

Not that it helps you much now, but I just re-sent you the "Lamp door warped and possible no power condition/KDFxxWE655, KFxxWE610, KFxxWE620" information package. Only today I discovered that I failed to include the attachment that includes color photographs of everything that should be checked out.
Thank you jehill to the naked eye everything looks clean etc, i have read that its a matrix that becomes damaged? if i new what the matrix looked like, and i have also read that no one has repaired one of these by simply replacing one or two lenses,or individual lcd panels, oh well onwards and upwrds!!

Sony doesn't provide disassembly instructions for the optical assembly, because it is considered something that should only be attempted in a clean room, such as those where the assemblies are rebuilt and aligned before shipment. They do provide an optical assembly cleaning procedure that indicates what screws NOT to touch, but its probably too late for that information in your case. However, I just sent the procedure to you anyway.
