Fault and repair guide

Because of its age spares are not easy to obtain for the VTC-9300.

Tape transport is sluggish or 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.

Sluggish threading and capstan problems

The bottom bearing on the capstan motor is prone to wear and because this motor also drives the threading mechanism threading can become sluggish. When this happens you will hear a horrible squeaking noise!

Blurred picture

Here's a tip for Sanyo VTC 9300/9350/Fisher VBS-7000 users. These models are known for having poor playback resolution from when they were new. Adjusting the Expand (VR216) control in the luminance circuit will sharpen the picture.

Don't adjust it too much otherwise the picture will be too sharp and grainy. The factory specification is 1.35V measured in the base of the transistor Q258. A setting of 1.1V should make the picture look much better.

Many thanks to Fivos Sakellis for this tip
