I replaced the digitizer board that connects to the screen and the screen cables and that fixed the problem.

The digitizer board and the LCD cables that connect that board and the screen to the motherboard.

Yes there is a board behind the screen. It attaches to the digitizer. That board and the cable that runs from that board to the motherboard.
