Panasonic RR-930 microcassette transcriber. Rewinds, fast forwards ok but there is no sound with or without head phones when trying to listen to tape even though the tape is advancing.

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

If the foot pedal is pluged in, press the play button and then you should be able to activate it with the pedal.

There is a rubber drive belt that needs to be replaced, Panasonic part RDV101YA. This place says they have them:

I've never had to work on one of these so I can't say exactly what you might have to remove to get to the old belt and pulleys it rides on. But it's usually not too bad of a job to change a belt.

If neither rewind nor backspace work, the common problem would be that the solenoid grease has dried up and the solenoid is not retracting all the way. However, the track that the mechanism moves in also wears out, as well as the plastic rocker that depresses the rewind button where it engages the metal slide.

If backspace works but not rewind from the pedal then the problem is the pedal.

Start by cleaning the capstan roller. The rubber roller and small steel rod just above it, control the tape speed. Just a little lint, build up or animal hair wrapped around this can cause the speed to vary. Clean with alcohol and a Q-tip.

There is a switch on under the tape deck that wears out or comes loose. This is something that needs service. We can fax it. 8663219780
