Not sure what would be causing this but the ball in play digit is displaying on the first player display. All cables are in the right place.

What happens in the display test?

The digit on player one looks real goofy.

Did you try a new ribbon cable yet? I never believed a ribbon cable would make a difference myself, but my F-14 displays were a mess, nothing but garbage on the displays, I thought for sure it was a board problem. But before i dug into that i tried swapping my ribbon cable from my Pin-Bot into my F-14 and everything worked perfectly!

I'd try swapping one of the ones between displays and the display processor board (the individual display cables on each display) then if that doesn't make a difference try replacing the main cable from the display processor board to the MPU.

Finally got back to working on pinbot. Looking though the schematic and after testing the 7180/6118 chips which tested good I decided to swap u5 and u1. And found the issue moved to the player 2 display.
