I got one of thesento work on for chirstmas. The tv turns on for a second showing the top left input hdmi/ dvi. The main boar responds to on and off and the light blinks but nothing changes on picture. I tested all votages to be good and steady. The y main board emmits loud buzzing that goes away when pic dose. Y buffers i think test fine no shorts.
When i short pson to gnd and test pattern pins i get no pattern and tv still cycles with no pic at all when with main i get input. All votages test good on psu. Im. Guessing x, y main or logic board.
