JVC Turntable won't turn, motor works, can't remove platter
I just bought a turntable at a garage sale this weekend (JVC JL-A20) and I plugged it in and turned it on, and it will not spin when I move the arm over the platter. When I remove the mat and look inside one of the openings of the platter (while plugged in and the arm is over it) I can see a copper looking round thing which is what I believe is the motor, and its spinning and will stop when the arm is placed in its original location. I try removing the platter by simply pulling up on it, however it won't come out. Do you think the only problem is getting the motor to turn the gears? And if so (and if I need to replace the belt), how can I do that and how can I remove the platter? Thanks for your help!

The platter on the JVC LA-10 does not come off as most turntable platters do. It is attached to the spindle with a Philips head screw.
Here are the steps:

Turn the turntable on its side and remove screws that hold the top to its base. Remove platter by unscrewing the bottom plate from the turntable. The spindle bearing is held in place with a Philips head screw. Loosen it and the platter will separate easily from the spindle.

Some turntables only move when you move the arm to the record. If that doesn't work and you have read the set up instructions correctly, as it's new contact the maker or the place you purchased it from. I'm certain they will help.
take the platter & belt back off, then check to see if the motor spins, if it does the belts the wrong size or put on wrong, if it doesn't spin then you better get your butter & jam out, to put on your toast.
Even if the belt looks fine it's almost certainly the problem. You mentioned "cleaning" - if you got any kind of fluid on the belt it might act as a lubricant and reduce the friction between the belt and the drive wheel, causing the turntable to slow when the tone arm puts a drag on it. The problem may go away when the belt dries out.
