Hey guys I need your help. I picked up an older Star Explorer machine last night and got everything working except several of the solenoids. I'm a beginner so I'm trying to track down the problem. I've seen a lot of posts on here saying that you need to change the fuse, however I don't think this machine has a fuse. The weird thing is that there is a switch on the back that will fire the solenoid side bumpers and sometimes the ball launchers. It used to fire the solenoid for the hole in the middle where the ball gets stuck (whatever that is called). But that has stopped working. Also, every time a light flashes or something electronic happens I can hear static in the speaker. The flipper buttons and the start button work fine but they don't activate anything. I did notice that every thing runs to a connection with a 20ohms transistor. Any help would be greatly appreciated -- I'm trying to get it up and going for Christmas.
