Fault and repair guide

No reel rotation

This is a very common problem which can have several causes. The first thing which fails is usually the reel idler assembly. Replacement units are readily available and can be fitted easily after removal of the cassette carriage. Next suspect the drive belt which connects the ideler to the motor. Finally the motor itself is prone to failure.

No tuner input

This is usually caused by failure of the RF combiner / splitter unit. Unfortunately it is not easy to repair this unit.

Timer and/or standby LED fail to illuminate

This is caused by dry joints where the LED are soldered onto the front PCB. In order to gain access to the PCB you'll need to remove the front panel and the servo board on the LHS of the deck.

VCR tape transport is sluggish

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.

VCR fails to accept or eject tape.

This is usually due to wear and tear on the cassette carriage. Best remedy is to replace but this is not pratical these days.
