This is a similar case to this thread
Picked up this unit from a guy who said he took it to a repair shop and they weren't able to fix it. The TV turns on, backlights and sound both work, but there is no picture. The thread linked above had an issue with a shorted MLCC on one of the panel driver boards. I went through them all, and I couldn't find anything shorted (unless I was measuring them wrong).
All voltages going from the PSU to the TCON/Main look nominal. TCON is getting the 12V and it's passing through the fuse just fine.
One thing I noticed is that it looks like there may be a diode that is missing on the far left (looking at it from the back) driver board...D104. There is a matching spot on the right side (D204) that has the part still in place. I have no idea if it is the exact same part, but I would tend to believe it probably is. It has 6514P 1829 marked on it. Unfortunately, I am having zero luck finding this part online anywhere.
Anybody have any advice?
