I have an Aiwa px-e860 fully automatic belt drive turntable. Yesterday I noticed while playing a record, all of a sudded it would speed up really fast and then slow back down, I thought maybe the belt had come loose, so I took off the platter and reattached the belt. Now the turntable either spins too fast, or wont spin at all, it keeps going back and forth. Also, the "start" and "cut" buttons for the arm dont seem to be working right either. Can someone please help me?
At this point only a service technician can help you. There is nothing you can do on your own; it requires the service and testing devices of a qualified repair shop.
