The Cinereels are wider than the upright 5 reel, but narrower than the upright 3 reel. If the problem follows the reel, then it's the reel controller board on the reel itself. These go bad from time to time as it has happened a couple of times to my machines. The controller is the same in the 3 reel and the 5 reel uprights, I don't see any reason to believe they would be different on the cinevisions. If you can't source a cinevision reel, you coud buy an upright reel and harvest the reel controller board. There should be a PCBA number on the board, post it so we can verify if it is the case.
