Hi Gang,

I need to start troubleshooting an issue with my Pinbot Face flashers.

Here’s what I know:
Likely power supply going bad. Errant problems on turn on. Early on after turn on game will reset, randomly shut down and go into attract mode.

Once game warms up it plays normally. Important to note symptoms are worse when my garage is cold.

But as I stated earlier when everything warms up game plays normally except for there are no face flashers during multiball, game turn on or game end.

The top red flashers on the cabinet work OK.

Any ideas where to start?

Thanks

Yes, the power supply probably needs replaced or rebuilt by now, but that shouldn't affect the flashers. Are you referrering to the "eye socket" flashers in the playfield? Firstly, are the bulbs good? Also, they need to be the correct bulbs... they're not normal #89 bayonet style... they're a higher voltage like a 1251 or something like that.

The face flashers on the back cabinet. They worked a little while ago, no changes/replacements since they last worked.

Face flashers - are we talking about the 2 flasher bulbs in the center of the backbox? Or the (4?) bulbs at the eye locks inside the visor? In either case, those are all #1251 flashlamps (28 volts) and not #89 flashlamps (13 volts) like the rest of the game's flashers.

FYI page 27 of manual shows the wire colors and board info for them.

Yes the 2 flasher bulbs in the center of the back box. They worked at one point, and have not been changed.

if the bulbs are the proper type and test good, then here are the details:

Both of these bulbs are 28 volt #1251 bulbs. Have you tested them to insure the filaments aren't broken?

So it looks like the face flashers have a dedicated solenoid. Time to open her up and check the bulbs . . . Fingers crossed

Problem resolved and I’d rather not tell you how I fixed the problem . . . but I will say 1251

Thanks to everyone who helped

You'll get a few flashes out of the 89's before they get blown to kingdom come!
