I haven't opened up the machine yet, but last night I played Stars for the first time in a couple months as it is inside the house and during the summer we tend to play in the garage.
But besides that about halfway thru each ball the flippers just die and one of the displays looks a little garbled, but as soon as it kicks the ball into the shooter lane for the next ball, they come back to life. Every time.
I'm sure it won't be too hard to troubleshoot, maybe a bad connection, but I thought I'd get some advice on what to look for before I tear into it just in case. And if not, I will post whatever resolves it.
