After turning on my spider man game this evening, my son realized that he was getting points simply by activating the flippers. I don't know if something was touched and it changed a setting, but I can't figure out how to put it back to normal. When he hits the right flipper it gives 20 points, and 10 points for the left flipper.
When you are energizing the flippers, it is tripping another switch.
First, turn the game off, reseat the connectors on the driver board and the interconnect harness (connects the MPU to the driver board).
Second, check the lugs on the flipper coils to make sure the wires haven’t come disconnected (broken solder). If they are ok, check the playfield switches to make sure none of the leafs are getting inadvertent contact or arcing. Check the rubber tension on each switch too.
Ok, I'll check them. The points are going up if I even tap the board or the side of the game. Any vibration activates the scoreboard.
Quoted from Joeynelyse:Ok, I'll check them. The points are going up if I even tap the board or the side of the game. Any vibration activates the scoreboard.
Check and reseat all of the connectors in the backbox, and in the cabinet. There are also two pop bumper control boards on the underside of the PF, closest to the backbox.
You have a switch with a gap below specs. Take the glass off and start a game. Touch every switch. My guess is one of your 10 pointers is the culprit. Most likely a band moved slightly on a slingshot or something. The vibration from the flippers is enough to cause a scoring switch to make contact. Don't forget to check the ones on the pop bumpers and behind the drop targets. When you find it widen the gap slightly. You should be good. The other possibility is one of your diode board diodes failed (it happens on Gottliebs).
