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?

probably not the motor but something to do with the voltage regulation.  Motors hardly burn out.  Check the wires to see if there is anything loose.

thanks to all, I saw a pretty good video of the insides of the Pioneer and I think I'll be able to walk him through it and show him what to look for.
well my Son took the platter off and discovered the voltage switch was on 220v instead of 110v....he'll be testing it in the next few days to see if it will play normal or if this may have caused a permanent problem.
I think you'll be l fine but if you were to do the opposite 
putting in 220 on a 110 setting well all bets are off.
