This game had sat for several years without being played, so there were a few issues to fix up. First, the display was garbled and you couldn't make anything out. The text could actually be read if you knew what it was trying to display, but only some parts of the characters were being lit. This pointed to a data issue; the ribbon cable turned out to be faulty. New ribbon cable in and the display worked fine.


Next, balls weren't getting kicked out of the trough. The armature which pushes them out of the trough was bent at a weird angle. Bent it to make better contact when striking the ball, and it started working consistently again.


A couple of switches were being dodgy on the coin door. Specifically, the diagnostic switches. Sometimes they worked, sometimes they didn't. A quick look at the schematics. These switches are all directly connected to the CPU board rather than going through the matrix. And they are all controlled by U16 on the CPU board. Surprise, surprise, U16 had been nuked by battery corrosion. Refurbed CPU board was swapped in, and the switches responded normally.


Captain B-Zarr is a cool feature on Party Zone. But on this game, he wasn't "talking". His mouth is meant to move up and down in sync with the speech effects. Took the assembly apart and found the wire that connects the mouth solenoid to the mouth flap was broken. Fashioned a new one out of heavy gauge wire and he was back to his chatty self.


Finally, a good clean of the playfield with new rubber rings to replace the broken ones. Night and day difference! Ready to party again! 💃🕺
