First, let me say that I'm relatively new to the Pinball repair game, so bear with me please.

I have a Bally Mystic (1980 SS) that started having an issue a few days ago.

None of the solenoids on the table will fire. It starts up, resets, and seems fine to start. Press Start Game and a game will begin with the score resetting to 0. However, none of the solenoids fire. It used to do a reset before the ball kicked out, and now nothing. The flippers don't work. The solenoids don't work.

When I run the diagnostic tests, the solenoid test runs through the diagnostic for all the solenoids, and it doesn't show any errors, but none of them work.

I've done some reading online here on Pinside and other sites.

I've checked the under the playfield fuse, and it appears to be fine.

Now, we did have some intermittent issues with the coin door. The machine is set on Free Play, but there was a time a couple of weeks ago, when we had a similar issue, that we just checked the coin door connections, and that seemed to solve the issue then.

I've read that the Solenoids are all on one circuit, so if power is cut to one of them, the ones earlier in the chain won't work. Could it be an issue with the Coin Door Solenoid, do you think? Is that the first in circuit on these Bally early SS machines?

Or, do you think it's a board issue?

Any thoughts would be greatly appreciated. Thanks,
Patrick

Thanks everyone for the replies. It turns out the solenoid driver board was shot, and that was what was killing all the solenoids. Ordered a replacement board, installed in 5 minutes, and the game plays awesome now. Thanks for the hints.
