Re: Acer AT4220 - colour/contrast problem

Hi Mikoz
I have exactly the same problem with my AT4220 TV here down under in NZ. In addition I also have a cyan coloured line down the RHS about 2 inches in.

My power board also hums a bit - so prob nothing to worry about.

If I detach the cable from the main board to the panel there's no funky colours or anything I.e. Screen is plain black with the glow of the backlight leading me to think the panel is fine as MRX pointed out above.

My thoughts are the main board is stuffed.

Did...
