Hi folks
Picked up this TV that had cycling Amber / White. Sent the board to Nick's TVs for repair.. after 4 attempts, I got the main board back with Proof of operation video.
It's doing exactly the same thing in my set. Amber / White flashing - then white, then repeat (Ethernet port shows activity now) I don't get any picture, backlight, or any other sign of life
All fuses on Main, and Tcon are ok. 12V is not coming on - and I can't really tell if the Main is issuing the ON signal - However in the process of removing the PS card (I was going to solder wires to force set on), I noticed a black charring around R38 and some on the leads of Q10 (See photos) - might explain why the 12V is not coming on.
Any thoughts on how to repair this? Anyone with a schematic that can help me troubleshoot this board? Replacing the Transistor would fix it? I don't know the value of the R38, but it's reading 635 kOhm
Thanks
