Re: LG 50PA5500 no picture

Update: Pulled the upper y-buffer and hooked everything back up. I now have half a screen . Yeah! I just ordered another upper used board and I hope that's it. Weird how the y-sus goes to low voltage and pulses with the bad buffer installed.

OK, I followed a thread on fixing this TV but it seems to have stopped before I got all the info I needed. So far here is what I've done. Replaced the power supply (it was bad for sure) and moved on to the Y-sus which showed very low and pulsing voltages witht the buffer boards connected but about 190 and 50vdc with them disconnected. Replaced the y-sus and buffers and put the shorting plug into the control board with the main board disconnected from it. The screen lit and went thru one test pattern and that was it. Re-checked the y-sus and the voltages are down again so I disconnected the boards...
