Was given this new TV that has backlight but no picture.
- When both T-Con ribbon cables that run down to the driver boards are
connected, I get no picture - just backlight.
- When I remove the left-side ribbon (facing back of TV), no picture.
- When I leave the left-side connected and remove the right-side ribbon cable, I get a good image on the right-side of the screen. Seems to be exactly half the screen.
- I've swapped ribbon cables and there's no change so I know the ribbon are good. I've inspected the T-Con and driver board and don't see any obvious burnt or missing components. (not that I expected to)
QUESTION: Is it more likely that the problem is with the T-Con board or the driver board? OR, is it anyone's guess?
Any suggestions on further troubleshooting? Do I start looking for shorts, etc.?
