Tape transport is sluggish / fails to rewind

Internally the VCR contains many drive belts which are used in the mechanics of tape transport. With age these belts become slack causing malfunctions and when this happens the whole lot should be replaced. In particular for the rewind function you will need to replace a tyre on the supply reel.

Audio not erased when recording

The bias oscillator had a tendency to fail in this model.
