Re: Sceptre X322BV-HD*WXC100 no picture and no sound
So....let me get this straight.....
I have a Proscan PLCD5090AB in need of a main board. IF I buy a T.RSC8.10A 11153 board, and solder the proper EEPROM on it, all will be well in the universe?
Is the EEPROM the only difference between the different used for this board?

Re: SONY kdl40s2010 no power
Ahh, I found it. The T-Con fuse (CP101P) was toast. Temporary bypass and just like new. Placed the order today for a new one.
Thank you all for the advice and assistance!

Newtothis - The only fuse I see is near the AC input. This tests fine both visually and with a meter. I am only getting one relay to click when powering up (RY6003), The other (R6001) never clicks over.

Re: SONY kdl40s2010 no power
And I cannot find any Standby 3.3 voltage nor a standby light. I am guessing that something is stopping the 3.3. which, like stated above, is preventing the rest of the system to power up.
The hunt continues tomorrow!!!

Re: SONY kdl40s2010 no power
And I just tested the old diode out of the board and it appears ok....and new diode is passing voltage both ways. Now I am really confused.

Re: SONY kdl40s2010 no power
OK. Did not see a fault with D6305 so I did not replace it. I did see a fault with D6306 which was listed as a D1NS4-TR2. This was replaced with a NTE585 (that's what they said was a replacement). I also replaced C6315 and C6309 (But they looked alright).
That said, it now powers up, but I cannot get a picture. no Menu no volume and no flashing lights. But I can see the backlight!!! Any further advice?
Thanks!!

Re: SONY kdl40s2010 no power
I just acquired a set with the same issue. Preliminary testing indicates that D6306 is bad and allowing current both ways.
My question is this is referred to as a D1NS4-TR2 diode. When I search by that number I am finding few results. I do however find LOTS of just D1NS4 diodes for sale? Is the TR2 a meaningful designation? Or do I simply purchase the D1SN4 diode?
Thank you!
