This TV shows all white screen, sound OK.
Panel is an AUO T220SW01 V0, 22", 4xCCFL. I expected open T-CON power fuse, but no luck this time. Fuse is OK, and there’re 5V at test-point. Also measured 3.3V and other voltages.
I see that after a while, some bluish smudges appear slowly on screen.
I’ve tried to connect a ChiMei M190A1-L02 (that have the same LVDS connector) and it works, so it seems a panel problem, as expected.
After some observation, I see that there’re about 5-6 horizontal lines of active pixels on top of screen. They contain no valid image. Seem like alternating white and black pixels.
Anything I can do before giving up?
