I have a DENON Fully Automatic Turntable System DP 297. I had been keeping it in storage in a box in my new home for some time. When I got it out and plugged it in, nothing happened. There are simply TWO controls on the right side of the front panel: 'START' and 'STOP'. When I pressed the 'START' button I could hear a faint whirring noise, so I unplugged it and removed the rubber disc on which the records go, then I lifted the metal table to have a look. I could see the little brass spindle which had been making the whirring sound. I know because I plugged it in again and saw it spinning. There is a long black rubber-band like belt going around the spindle and around all the flanges in a sort of circle. This band was not being pulled or affected in any way by the spinning spindle. I then unplugged it again and removed the base to look inside. I can't see where the spindle should connect with the central gears to actually start the table turning. Can you tell me what part of the mechanism is supposed to interact with the central post around which the table sits? I've had this turntable for a couple of years, but I had only used it a couple of times before I packed away when I moved. I can't imagine there are any parts missing. What do you suggest?
