No pictureThis VCR suffered from bad head wear. If you are getting a distorted picture then be sure to check the head.
Failure to load a tapeThis is often caused by failure of the cassette carriage.
No reel rotationThis is a very common problem which plagues all Sanyo machines and 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 thing to check is the drive belt connecting the motor to the idler assembly. Finally suspect failure of the motor itself. It can also be caused failure of capacitors in the servo circuit.
BeltsThese machines develop rubber belt and drive wheel wear and ageing issues similar to the Sanyo models and the rubber stretches, goes hard or cracks causing drive, tape load/unload and control issues. They can usually be restored to service with a new belt kit and a good head clean.
Playback interference from the reel drive motorAnother common issue on these machines is a worn or faulty reel motor. The motor starts to generate small arcs internally which are picked up by the sensitive video head amplifier circuits via the power supply. These are seen as random coloured dashes on the playback video. Adding extra capacitors and high current (low resistance) inline ferrite beads inline with the motor supply wires can partly reduce the problem but replacement with a new motor if you can get one is the best fix.

|No power - No clock||F801 open circuit. Replace with 630mA Slow blow fuse.|
|New heads||The replacement heads for the V-31/V-33 models do not self align like the later Sony models. As a result, it is neccessary to use the proper eccentricity gauge to centre them correctly.|
