If your lucky it just jumped a gear, but there are several other things that could be causing it; a bad power supply, bad or disconnected sensor, foreign object (cassette label, grilled cheese, etc)

Take the cover off and try to cycle it by hand, of course you will unplug it first, right ? Chances are it's the first item and you can gently re align the gears.

If it's something else, i think it's easier to just get a new one. I'd guess you could do that for like 50 bucks. Maybe less at a pawn shop.
