Greetings,
This is my first pin that I picked up for super cheap a few weeks ago. When I tested it before buying just about everything worked. I've cleaned the machine, rebuilt the flippers, replaced the rubber, and made all required repairs. I am experiencing one issue I could use some help with though:
Sometimes I power the pin up and everything works as expected. Other times none of the playfield lights will light up when powered on but they will all flicker anytime a pop bumper or sling is struck during play. This includes the pop bumper lights that should only light once the ball enters one of two upper holes and all the insert lights which only one should ever be lit at a time. Cycling power doesn't seem to solve the problem. It will work fine for a day or two and then back to no lights/flashing when struck for a few days, and then back again.
What should I be looking for? Any feedback would be greatly appreciated.
