I have several LED's installed in the PF on my Surf Champ. They really make the features stand out and I like the look. I have an issue however. for most of the the non-GI feature activated lights they work fine and do not flicker. But, for the multiply bonus rollovers they flicker when not on. they flicker when there's activity in the game like scoring or activating the flippers.

I've done some searches but found mostly threads pertaining to non-em games and add in boards to manage it. I was just looking for some troubleshooting tips from anyone that might have dealt with this.

I do. I can post the schematic once I am out of work.

I can do that tonight after work.
