Hello All,
I am a moderator on the forum but due to illness I'm not as able to come on as often. Anyway, I have an LG 42PS3000 in. As usual no picture, Vs and Va ok, found a s\c cap and o\c resistor on y-sus. These feed and decouple voltages for the buffers. Now I have perfect lower picture but the top is modulated but grossly overbright. Can the y-sus board be the cause, I would have thought that as the lower part is perfect the y-sus is likely to be ok. I'm going for the buffer pcb. Who is with me on this one, is any old fellow techies I used to converse with on here still around. Ta anyone?
