They were throwing it away so i couldn't pass it up.
Model: LC-70LE550U
Problem Description:
-When powered on all indicator lights and backlights power on as expected.
-95% of the time the screen is black, but backlights are always on.
-About 5% (maybe even less) when powered on you will see the full picture for 1-2 seconds and then the screen quickly fades to black but backlights remain on.
- I disconnected the left ribbon cable (see photo) (as sitting facing front of TV) from the tcon board and the right side (as sitting facing front of TV) works fine while the left side is pure white (see images). When I disconnect right ribbon from tcon board the left side remains dark wile backlights remain on.
- Swapped ribbon cables on tcon board and the problem is exactly the same regardless of which ribbon cable.
Researching this exact TV here at badcaps points to a driver issue with some tabs. I would rather check with this forum before going further-at this point I have only removed the rear cover.
Appreciate any help/suggestions.
