I have a Gottlieb Close Encounters machine. The scoring isn’t working correctly and has a mind of its own. It just randomly runs away so to speak. I don’t think it’s a result of a switch sticking. I’ve attached a few pictures of the inside of the head. Any suggestions as to what the issue may be? I don’t Also, I am not a pinball techie so any help is much appreciated!

it's clear the battery was removed. Was there any damage to the switch connector under it? Has it been recrimped/reflowed?

Thanks for the suggestion. It seems to be getting worse. The CPU is original. Do you think swapping it out with a new NI-Wumpf board would do the trick? It should probably be done anyway.

I would visually inspect the switch connector first. If the crimps are bad it won't be any better with another board.
Make sure the crimps aren't corroded, flattened or other wise damaged

I will do just that tomorrow. I’m learning something new everyday. Thanks for sharing your knowledge.

In theory if this is a board problem you should be able to start a game, pull that connector and the scoring will continue
