First, unplug one of the ribbon cables that goes from the TCon board to the LCD screen, test, then do the other ribbon cable. You end up hopefully with a half of a good screen. Anyway... clean the bad ribbon cable and also try to put a little pressure on it, maybe there is a bad pin on the ribbon / slot.
If that is the case, some folks make the ribbon cable thicker, by putting some scotch tape on the backside to increase pressure when the ribbon cable is snapped in.

I can see one ribbon cable which comes from the main board and it is pluged into the TCon board.Here are the pictures of the main and Tcon boards.

Oyyyy, that sucks. Only thing you can do is to clean the ribbon cable on both ends and check the tab bonds and the LCD.
