After returning the PCB back into my Ms Pac-man cocktail game I noticed a baffling issue that is now keeping me from playing. The screen is black, and the coin (play) counter on the coin door is ticking up and up and up.

This has happened once before and cleaning the PCB connector part did the trick. Now that's not working. Any ideas???
