I've got my game set up here at Allentown and it's getting a real workout, way more than at home. What's happening is after it gets played for a couple hours straight the flippers stop working completely. If I turn it off for 5 minutes they start working again.

Any ideas?

Sure sounds thermal, so look at bad connectors or sockets first.

The moment it goes down, see if the flippers have voltage at the coils.

Also, just to be clear, does the rest of the game still work even if the flippers aren't.

Usually when I get this description, it's the entire CPU that has locked up, but the sound is still working and some pf insert lights are sometimes still lit and of course the GI is lit, but the rest of the coils and switches are non responsive. Some times the score displays still have something on them but most of the time they are blank.

Check to see if the solenoid fuse holder is real hot. Or clip a meter across it monitor voltage there should be no voltage drop there and fuse and holder should not be hot.

The rest of the game works fine - just the flippers stop working.

I'll try leaving it on all day to see if I can get it to happen again and then play with the meter attached. Thanks for the suggestions.

I recently purchased a Firepower and I'm experiencing the same behavior -- After a few hours of use the flippers stop working but everything else is working correctly. I turn it off for a few minutes and the cycle repeats.

fantasygoat, were you able to resolve the problem?

Our lost world was doing the same thing recently. It was an intermittent relay. Swapped with another one and the problem went away.

My relay was fine. I replaced the driver transistor for the relay and fixed the problem. Sorry for not updating!

I apologize for being a noob -- Where are these components on Firepower?

Thanks!

Oops, missed your post. The relay and associated transistor are on the driver board, left side middle.

Just wondering if someone can point out the exact resistor that was replaced? Is it R20, R25, R27? Thanks.

I think jwilson was referring to transistor Q13 just below the resistors you mentioned. Looks like a 2N4401.

Hope he pops on and clarifies this but in the meantime have a look here...

I think my issue is the flipper relay. I left it on for 2 hours until the flipper stopped working, and then tapped the top of the flipper relay and the flippers immediately worked again. Am I correct this tells me to replace the relay? And if so, is this the part: http://www.marcospecialties.com/pinball-parts/190-5001-00

Yes, just a simple 2N4401. Usually the relay is what kicks it, as in your case.

Sorry I dont know without digging around a bit.
