After tuning on Space Shuttle, in about 5 minutes, there is a loud hum from the game. Game does play fine. And sounds do work.
Anyone know the problem?
Thanks
i believe thats a system 9 like my sorcerer.you can read my posted questions on here what i tryed to fix problem.but cutting to the case do you have a hum.i did and it ended up being my u11 processer 6808 chip was bad
make sure your sound boards are all tight to backback some times this is a ground issue.you can check mr pinball repair section for this issue.i know i read about that once.good luck
Mine has a hum too. Haven't located it yet. Everything is tight in the backbox. I don't have speech on mine though. Hopefully when I find the cause of the loss of speech, I'll also find the cause of the hum.
