Quoted from Hunterxero:
I think I have the same problem, did you ever come up with a permanent fix for this issue? It sounds like I'd have to get a new SAMS board.

Sounds like he replaced a capacitor on one of the main LED Boards in the middle of the playfield.

OP
Quoted from dschulpius:
Resolved: When I got to the main LED board in the center of the PF (with the Bridge Rectifier and fuse on it) I got a real nice and consistent flash of all lights when I tapped on this board. This had to be the location! Looking closely I saw that the little L1 cap was bent slight over. Pushing on it caused all lights to come on completely!
I can now see that one leg of this cap is broken. I'll need to pull this board and solder a new one in there. When complete I'm sure all will be working again.
