Panasonic RR-830 only rewinds and fast-forwards, will not play

I just bought a transcriber from someone local I found on Craigslist and, although they said it was brand new, it does not play. I know that buying a transcriber without testing it was not a good idea, but I'm a struggling student and was trying to get a transcriber to use a home to help me improve my medical transcribing skills. Does anyone have an idea how I might fix the transcriber; I might as well take the thing apart since it does me no good in its current state. The electronic repair stores wanted $40 just to look at it.
