Hi all, I fixed up a TMNT for a friend and all was fine, had the machine at his place and there was an issue with super weak flippers and one of the launch ball coils not firing. We moved the table to where it will stay and then it was OK for a couple of hours, now I hear it's gone all weak again. I looked at diagnostics and can't see any loose wires - all seems OK so I'm at a loss with what else to check. It would appear it's some short perhaps or poor connection - any ideas or suggestions to check?
