Touch screen not working.

The touch screen isn't working. I purchased a Surface Pro with a bad battery and broken screen. Touch screen was working initially before screen replacement. I've tried two different screens so it doesn't seem to be a hardware issue. All of the drivers appear to be installed properly. I ran the hardware check and everything passed except the touch screen. Is there something I could've broken when replacing the screen and battery?

There could be missing components from the tablet's board, are you able to look closely around the display connectors to look for any missing parts?

I don't see any missing parts. I connected everything that I disconnected when removing the original screen. Both ribbon cables are connected properly to the panel and the board.
