Am having an issue with a 1979 Sharpshooter by GamePlan. While ball is in play in either 1 player or multi-player mode the score displays reset to zero. This happens regardless of whether a drop target, pop bumper, sling or virtually any other target is hit. I tried re-seating each of the four score displays as well as the score connector on the MPU. Didn’t help. Doesn’t seem to be a score display problem but one that is electronic/circuitry related.
Anyone come across this type of problem and can suggest something for me to try? Thanks!
