My Williams Firepower has been having an intermittent problem, which I know is more difficulty to figure out. Plays well for a number of games, then almost randomly, it shuts down in the middle of a game. The backglass just says “Game Over” and all lights on the playfield flash. Restarting another game results in the same thing happening.
I went thru all the diagnostic sequence per the owners manual - and everything seems to check out. I also looked at the coin door tilt mechanism. Cleaned it up, filed it down, and tried to make it a tighter connection (I believe the switch is supposed to be in the open position at rest). Not sure what else to try. Any ideas?
If anyone has experienced this with theirs, or heard of any possibly causes/solutions please let me know.
