There is a leaf switch on your playfield somewhere that is too close and the vibration of the flippers, pop bumpers, top hole eject and slingshots will cause them to touch and score points. Do this slide your playfield glass off and start a game. Tap the middle of your playfield with your hand lightly then progressively harder until you hear the points ring up. Note how many points it is each time, 100, 500, 1000. Then look at what scores that point value such as stationary targets, lane roll overs, drop targets, etc. Most of the time on that particular machine it is one of the 5 stationary targets on the left side. Then adjust the switch just a little wider apart until the vibration will not cause it to make contact with each other, just insure that the ball will though when it hits it during game play. Hope this helps and good luck, that's great machine to have!

Hi
Thank you very much for the hint!
This is a good thing to try.
I will do it and get back to you with the result.
I already checked everythings on the selenoid board and every parts are good.... i will try your testing method...
Thank you very much

You can also enter into the switch test and watch for the number to show when you tap the playfield.
