Tapes won't go down, and then eject.

You are more than likely using a pre-recorded tape and a timer programis set to record. If you are trying to record, make sure the protectiontab is in place.

Theres a possible stuck object or part inside, better to open the unit and check on inside if there a an object stuck

Sounds like a mechanic problem, check for fragments of tape inside.

Check the spring that is working or not.......
that spring is inside the try area....

Have you tried to force eject the cassette. May be the ribon of the tape has come out. Try using another cassette.
