I was in my home office and a "brown out" hit my house. The lights all dimmed and buzzed, my computer shut down. It was over in a handful of seconds. A couple hours later I went downstairs to play my Tron, turn it on, dead.

I opened up the coin door, and could smell smoke. I unplugged it, looked around, and could see the 8A fuse on the power box was blown. I replaced it, plugged it in, and immediately heard a sizzle and pop, then could smell more smoke.

I unscrewed the metal housing, and saw this!

Anyone ever deal with something like this? I'm guessing even though my Tron was not being played at the time of the brown out, the service outlet is on 24/7. My other games are not affected. All the games are plugged into power bars with surge protectors, but I guess it can't stop this from happening.

I don't even know the first thing of having to repair something like this. Anyone ever have to?

Do they sell replacement power units? I've never seen one. Does someone have a link?

thank you. are varistors rated differently? is there a particular type i should get?

We replaced the varistor. Radio shack sold 3 different colors, so we used a red one to replace the red one in the machine.

The game was able to run with the varistor removed completely, during our diagnosis. The new one was soldered in and everything is back to normal.
