I have an unusual issue with flashers on my Jokerz. For 90% of the time, only one orange tower flasher works (as pictured). The back of the playfield, backglass, other towers, and draw poker wheel flashers do not light up. Then, occasionally, without doing anything but playing it, they all light up appropriately. I am missing something somewhere. Bulbs are new, doesn't matter if I have LEDs (which I do) or conventional. The draw poker wheel lights never light up. I am a veteran at fixing pins, but this one is alluding me. Thoughts?
