Hope you can help. I have a Nordamatic " Champion" table, similar to the gottlieb 300 table, which I got up to working condition over a year ago, and have not had a problem since. However we had some people around for a party and people were playing it whilst I was elsewhere. The ball got stuck in one of the holes ( sorry for the non-tech description ), and wasn't thrown out. They tried lifting the machine that resulted in a tilt. I pulled the glass and released the ball, and the machine reset played fine all night.
I came back to have a quick game the next day, and it won't reset correctly. It simply churns away without throwing the ball into the run, and just goes around in circles. Any help would be great. Thanks
