Mine did the same thing. First plug the motor directly into the wall to make sure it is the SDS and not the motor. Then cycle the SDS on & off a couple of times and see if you can get the table to run at 45rpm. Mine eventually started to work again after going up & down with the voltage & frequency. I use the on/off switch on the turntable and always give the clamp a little turn to get the momentum going, have not had a problem since.
