Nakamichi DR-10 Cassette Deck Repair

I am the original owner of a Nakamichi DR-10 Cassette Deck. This unit has been sitting idle (indoors, climate-controlled environment) for a decade or more. I recently connected it to my stereo system, and attempted to play (several) tapes. As soon as I push the Play button, it stops; i.e.: it will not play the tape. The Fast Forward and Rewind both work. QUESTIONS:

• Any ideas re: how to fix this issue?
• Any suggestions re: repair services?

Thank you in advance.
