I have bin trying to get an old cash wheel going so far I have had to replace the reels, both power supply, 1gb board, and everything works except for top box. It lights up and the wheel stops like it is going to work then the lights go out and wheel starts spinning again. A errors go off for a second then it says top box com error, top box device error, lamp projector, top box not configured. I have tried swapping out the board in the top box, the board behind the reels, usb from the main board all the way up and still does the same thing. I ram cleared the machine each time I changed out components. I'm thinking it might be the board behind the tray in the top box but I don't have one of those I can swap from another machine. Is there any thing else I might be missing?
