A couple of months ago I got a LG 50PA5500 Plasma TV from my brother for free that wasn't functioning but fixable. I have a fair amount of experience repairing electronics so I figured I'd take a crack at it. First thing I did was take a multimeter to every board to test fuses, resistors, etc. and after substantial research cam to the conclusion that it was a bad board. I've since replaced everything but the Z buffer and the power supply board. At this point just seeing if maybe I'm missing something or if it's the screen itself that's bad. I'm not too worried about reselling the parts but I am kinda stumped/feel kinda dumb at this point. Any help is appreciated!
