Welcome to Agoraquest!  Are you looking for the service manual or the C-81 service bulletin?

Service Bulletin E16031285 was issued on 8/6/2003 to address this issue.  The cause and resolution are as follows:



CAUSE: Transistor Q002 malfunctions. 

RESOLUTION: Replace Q002 with HOUSING (Q002) ASSY which consists of a higher capacity transistor (2SB1375), and socket. Also replace R011 (1K ohm) with a 470 ohm resistor.

Recommend that you take or send your unit to the nearest authorized Sony service center for installation of the modifications identified in Service Bulletin E16031285.



Can you please email me a copy of the service manual for the DAV-c900 to jpuma@sandlercap.com

My mom gave me her Sony D700 system because it had a C81 error, so all I need to do is fix it. I was an electronics tech "back in the day" but have been a PC tech for many years, but I havent forgot all those skills completely and have been following all 6 pages of this thread but Im just a bit fuzzy on some of the details.



> I didnt see mention of removing the old transistor, but I assume that you do.



> The whole "housing" thing was a bit odd. It looked to me that Sony so under-judged the transistor that the replacement wouldnt even fit in the same physical space as the old one. So the housing is simply a larger transistor that is prewired for you and mounted offboard? Is that gauge wire the minimun required for that transistor? It would be a lot easier to solder with a smaller gauge wire - Im sure I can make a "Q002 Housing" myself and just use heat shrink on the leads.



> Their alternative location for "Q002 Housing" seems ok, but any ground will do I think?



Thanks guys, unfortunately these days Sony isnt the company they once were and I find myself returning more often to Agoraquest for help. I hope that Sony tosses some dollars at the admins of this site because they are certainly doing Sony a favor.

I have a DAV-S800 with error c-81 .

Symptoms - Tuner/amp works ok, but no power to the DVD tray unit (won't open/close/play). It broke down while playing a DVD.

 

I have a couple of questions that I hope someone can help me with:-

 

1) without power to the DVD tray, is there a way to open the tray to remove a DVD?

(On a PC DVD drive I would push a pin in the small hole, allowing the drive to be manually opened)

 

2) I have managed to track down the components suggested in this thread.

1/4 watt 470 ohm resistor

capacity transistor 2SB1274 (size excluding pins, 15mm x 10mm x 4mm)

 

I removed the DVD board, and located the area marked Q002 on side B. The components that I am replacing seem to be very much larger than ones I have purchased.

Is it expected that the replacement components are significantly larger than the original ones?

 

Thanks to Agoraquest and all the contributors for a great website.

Welcome to Agoraquest!  Sorry, but Service Bulletin E16031285 doesn't apply to the DAV-S800.  Only the service manual is listed for the DAV-S800.

You will find that, in the service manual, at the back. There is an engineers fault code list. C81 tells the engineer where the fault lies.

I misread your problem, I think you will find C-81 means a mechanism lock up.

Hello,

Great Site.. lots of useful info.

My DAV-C900 has the same problem ( C-81)  and i was very relieved to find this site. I have opened the baord and removed Q002 and soldered wires to the Emitter , Collector and base terminals. 

Will go out and buy the NTE153 transistor which is the equivalent of 2SB1274 ( Sanyo part )  and complete the repair and hopefully it shd work

QUestion i have is the body of NTE153 is collector i guess.. don't you need a insulator before connecting the part to the Power board for thermal dissipation.

Please reply. I am waiting for your valuable feedback.

thanks to all for the great info.

thanks
Siva
