Just when you think everything is going smoothly, Firepower's Displays take a dump...

The game was powered on and played for around 7 hours today with no problems. This evening, I go to turn them off and Firepower's displays are all messed up. Game still played fine. I tried reseating the display connectors on both the display board and the CPU board. What happened?

"0_0_0" on the Score Displays.
If the score displays are only showing three of the six (or seven) digits of the score, this is usually not a problem with the master display panel. Instead this is a driver board PIA problem. If the lamp PIA (IC10) and/or solenoid PIA (IC5) have failed, this problem will often be seen.
