This thread help me bring my Sorcerer back to life.
I picked up a nice looking project Sorcerer recently. The owner told me that it needed "Attention" and that the game had some issues.
I started a game at the seller's home, and immediately noticed the displays were out (an issue he said he was aware of). From there, the game appeared to play fine. After maybe 25-30 seconds of play, everything froze and the ball drained. He told me that was the issue he was referring to. The game looked nice enough to roll the dice, so I loaded her up and took her home.
After re-seating all the connectors, the displays fired right up. Score! Now, to address the reset...
I went through all the test, and everything appeared to be in working order. Once in the switch test though, I noticed that switch 1 popped up without me doing anything. Then again. And again. I gave the machine a few nudges, and sure enough, switch 1 would register. Having read through this thread, I realized it must be one of the tilt switches. Sure enough, switch 1 is the tilt bob switch. I took the bob off and BOOM! We're back in action!!! No more phantom tilts, and my game is up and running.
I plan on going through the game a bit more thoroughly and then selling it to fund the next one. Big thanks to the guys in this thread for saving me a lot of troubleshooting.
