I haven't had the game long and this puppy is dead again. When I brought it in the house I noticed the upper opto that detects the jail bars being up wasn't working. I got a new opto from Stern, installed it, and all was well. About 4 months later a transistor on the CPU pops and upon replacing that, the same opto is dead again.
Not sure what to check next. I assume I could replace it again but it's just going to die after a few months. Any thoughts are greatly appreciated.
