So this doesn't happen very often, so I feel the need to celebrate the small victories. On a hunch I replaced the GI relay under the playfield of my Cyclone. It is a $20 part, which is a lot less than a power supply board repair or replacement. The GI lights were out on one side, so I thought, why not swap out the relay? Fixed it, now the game is 100% good. I'm stoked. Yeah!!!!
