Turntable problem

its a Pioneer PLX-1000. fairly new with hardly any hours on it.

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. 

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.
