This pin is driving me crazy. Day after day I'm getting a little closer to playing a good clean game but now I'm stuck on lamp matrix issues. I hope someone can dumb down a solution for me. I went into test mode for the single lamps. Every "single" lamp I tested turns on 2 or 3 lamps in the same row but different columns. Example: column 1- row 1 "Thing Multiball" flashes but so does "Upper Left Jet" in column 2- row 1. So each lamp test will turn on another lamp to the left or right column or both, and always in the same row. Every single lamp turns something else on in the same row but different columns. Something this big isn't just a short somewhere, right??
