Hello all I can really use some help. I picked up a close encounters pin with no boards in it. After some research I decided to go with the all in one flipp mpu. Once I put it in set it to the correct game I fired the game up. It does it’s thing but some things don’t reset like spin wheel and drop targets. When I press up a game it makes three tones nothing works and on the bottom display where it shows ball in play. It shows nE. Any one know what this could be. I can’t seem to find his email on the mpu site. So any help would be appreciated. Thanks you in advance.
