Hi, most likely this deck is suffering from the same issue that affects all duals at this stage that have not been serviced. It's the old grease in the mechanism that's keeping a lever from moving to shut the turntable off. I can see what appears to be old grease on part of the mechanism right next to the motor. The mechanism will need to be disassembled and cleaned of ALL old grease. Then fresh grease needs to be applied as the mechanism is assembled. Check the library section on this site for the service manual. Read it through a bunch of times and if you feel this is something you can do then give it a try. If not then try to find someone in your area that has experience with servicing turntables. I hope this helps.
