I just got this game today. I am puzzled by what has happened. I was changing some of the Led’s on the main playfield with the game on, like I have done in dozens of machines. When I was getting the led out of the lower left pop bumper, all the GI went out. I have checked all the fuses and all test good. The game plays like it should, but also no sound when scoring, just the music playing. Any help with what I could have done? Thanks in advance.
