I've had this Blue Chip for a few years. Every once in a while when you go to start a new game on the backglass it would count the balls up to 10 and the stepper unit kept going. You could just power it off and try to start a new game and it would work but now the stepper keeps running no matter how many times I power the game on and off.
I thought it was a problem with the ball count unit so I just now took a look at it. If I manually activate the step up and down coils it steps up and down cleanly. Everything looks clean and I'm thinking I serviced it when I first got the game. I'm not an EM tech but any stretch of the imagination so I could have done something wrong but it worked correctly for a while so I'm thinking it's something else telling the ball count unit to keep stepping.
Does anyone know what I need to look at next?
Thanks in advance for any help or guidance!
