A local Op asked me if I knew what was wrong with a game, because he is at his wits end.

There is a ball return selanoid that will pop every once in a while for no reason. He has changed out every thing that he can, but nothing has worked.

He called up STERN and they said to beat on the playfeild and that should fix it, It didn't. Does anyone have any ideas.

I'm not real familiar with the ID4 but I would assume that being a newer pin it probably runs off opto's if it does then either the optos are dirty or one of the lm339 chip that is on the opto board is bad. I have a world cup soccer that had a problem like that, an outhole wound fire every once in a while it would test ok from the switch edge but during play it would act up.
