Quoted from Trond:Thanks for the suggestions everyone!
Interesting video! Also: my ball also got stuck twice in maybe six games. Maybe this is a weakness in this machine? I noticed that the machine seemed to shake itself when the ball was stuck, and this loosened the ball once (the other time I had to shake the machine quite a bit). Is this shaking mechanism a common feature in pinball machines? (I hope I wasn't imagining things )
Yes newer games will fire all the solenoids in the game (called a ball search), so if a switch isn't working it will still fire the ball out of a scoop, saucer, etc.
