Just bought a used Williams 1978 world cup soccer. after bringing it into the basement, plugging in it worked good for about 30 min and then the driver board starting to smoke, that should have been a sign to me.
Called a retired pinball tech and he came out thankfully and repaired the old board.
after a week we started having other issues. always had a smell like it was over heating when we turned it on but it was working fine.
now the issue is the out ball kick, and all the ball ejects are not working. someone else told me to order a new board from rottendog so we did. installed a mpu327 which replaced the original driver board and the cpu board.
still is not working. we need some guidance. I am seriously watching all the videos I can to learn more about this machine but any insight you have would be helpful. thank you
