The turntable on my Sony Automatic Stereo Turntable System PS LX49P has stopped working, when you move the arm over the record, there used to be a click and the turntable revolved, but alas, no more. I know that it is not the belt as I have checked that. There is no motor sound at all. How can I fix this please? (I have had it for 17 years)
