Turntable problem


my Son's DD turntable quit spinning while listening.  he turns it off and back on and everything is fine for a few days but its starting to happen more frequently. I also posted this on tech talk.  any ideas?

You'll have to include the make and model. Probably something overheating on a circuit board from being old or the motor bearing is worn.
I would agree with noromance, if it turns off after  period of listening and it is approx the same time each time, check the circuit board for a burned or swollen capacitor. 
well the tt does not turn off just the platter quits spinning while the arm is still in the grooves of the record and all lights are on. he'll then bring the arm back to its rest, turn it off and then back on again and it will play fine for a few days then the problem happens again.
