Question Sharpshooter by GamePlan - score display prooblem

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. Didnít help. Doesnít 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!

Some of the best information about game plan machines can be found at pin repair.com, have you checked them out yet?
The problem sounds like one of the voltages at the cpu is low or too much ac is getting thru on the dc line causing reset problems.

Thanks pinballdaveh for the suggestion. I have since resolved the problem. It was the base of one of the 10 point switches that is behind the drop target "S" and "H". It was making slight, occasional contact with the metal frame that houses the 7 drop targets. By bending the L bracket holding that switch under play field so it didn't make contact when targets hit...solved the problem!
