Sega/Stern South Park – fixing opto/ball trough issues

In this video I pull a game off route and work on it. Discussing the unusual playfield hardware used by Sega/Stern. There was a problem with the optos in the ball trough causing problems making the game kick balls out onto the playfield unexpectedly. The game displays “too many balls” when there is the proper number installed.

Fixing drop targets on Stern pinball games (World Poker Tour)

I recently was tasked with fixing up a Stern World Poker Tour that had come off route. The game had a number of issues, the first of which was that certain targets would not reset. They would pop-up, but fall back down. Some research indicated this was a known issue that Stern released a service bulletin to address. But I soon found out my problem was deeper than that, and several things were wrong, including a broken bolt holding a coil stop, and the wrong plunger assembly used on one of the drop targets. In this video series, I outline how I identified and solved the problem. Here are some pictures of the work that was done to fix the broken bolt.
