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.

Thanks!

Thanks Schwaggs - I looked at both of those, and have them gapped pretty wide right now. That didn't seem to be the issue. Appreciate your thoughts, if you other suggestions am all ears.

Thanks HHaase - yeah, I know about trying to troubleshoot via forum strings....but, worth a shot. The 40-pin interconnect had been replaced fairly recently, but will look into that. Not sure which is the "slam tilt" is that the one on the coin door or under playfield? I did check them both & re-gapped them to make them more open & less likely to trigger. As to the coin switches....they seem OK, but will have to look a little closer to make sure there no unitended grounding going on. No other oddball stuff going on - when it plays, it's excellent...

Thanks wiredoug & boydsc331. Don't know about the bridge rectifiers so will need to look further. My power supply board is fairly new, but worth checking into again. Appreciate all the great ideas - at least I have something to possibly explain what is causing the problem.

Great suggestions everyone. Got some work to do now to isolate the issue. Hopefully can report back soon that all is well.

Thanks for all the suggestions....problem kept recurring, so decided to have a Rottendog CPU installed yesterday. As of now machine is playing well, hope it continues.
