Hey everyone. I've browsed this site pretty regularly when I need some pinball repair tips, but I finally signed up to ask you all a question.
I have a Fish Tales pinball that is giving me a little trouble. When I flip the power switch the game makes a bouncing sort of sound something like a "bum bum bum bum" that gets more rapid and finally stops and the game starts as normal. Here in the shop we have great electricity and it goes through this routine once. However, out on the route lots of our accounts have not so nice electricity, and when the game is in one of these locations it can go through this routine 4 or 5 times before it will start as normal (the lights come on for a second and go back out).
My thought was it was probably filter caps on the driver board, so I changed all those and ended up changing all of the rectifiers on the board, trying to chase down the problem. At this point I'm wondering where to start looking next.
