This problem is most likely caused by the T-CON board. It could be a bad connection of the cable from the LCD to the T-CON board. or the T-CON board could be bad. Sometimes you can disconnect and reconnect the flat cable(s) to the T-CON board and solve the problem. Else you can replace the T-CON board.

The T-CON board is the board that drives the picture to the LCD screen.
