LCD loosing backlight. Answered
My backlights fail only when I input a viveo source of any kind. If I power up in RGB with a composite video source pluged in its fine until I switch the source to composite(video1). this is true for any source. they include S-video, RGB, composite, VGA and tuner. its run on 12V, pretty much Identical to a computer monitor except more inputs. thinking maybe the inverter, any other ideas will be helpful???
