What's the symptom? What controls the solenoid? My recollection is that all those Tomy games are mostly mechanical. They're marvels of engineering really, nothing much like that is made anymore.
No kidding. I opened it up and just stared at the clockwork of plastic gears in that, just wondering who came up with this. I hope they enjoyed their job.

The Tomy games had great playability for a kid. I remember occupying myself with one of those for hours...
Anyway, the sympton is it does nothing. At all. The only three electrical components are a light bulb, a DC motor, and the solenoid. The DC motor was stuck, but that was an easy fix. The light bulb is fine, and (obviously) the solenoid works. That leaves me to suspect a bad solder joint. I've scrubbed the copper contact points throughout and I get continuity across them.
With no diagram, it's not obvious how this works, though it really shouldn't be that hard to sort out. I haven't really tried to diagram it yet apart from spending a half hour scouring the web, hoping to save myself some time. No luck.
