Fault and repair guide
Tape transport is sluggish or fails to rewindInternally 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 problemsThe 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!

|Loss of colour or intermittent colour in playback||Adjust AFC(VR - 214). If that fails, replace Q204(IC, CX -150) and surrounding electrolytic capacitors. AFC may need to be adjusted after these components have been replaced.|
|Double vertical image||Adjust VR101 and VR102 on W1 till you get the best image. Use multiple tapes to confirm. You can also refer to page 10 of the Sanyo VTC9300 service manual for instructions. This requires an oscilloscope and alignment tape for best results.|
|Bad tracking at center position||Misaligned audio/control head position. Loosen the 3 screws that hold the ACE and then slide the ACE assembly forwards or backwards until you get a perfect picture with the tracking control at the center position. A known good tape and a scope is recommended for perfect adjustment.|
|Output image is black and white||(Possible, simple solution)|
Make sure that the "TEST SIGNAL SWITCH" is set to the "OFF" position (Bottom position). If this was the problem then the image should become coloured instantly.
|Very slow lace up||Apart from replacing belts... very slow lace may be due to the lacing gears under the capstan flywheel seized up! There are three gears and the grease may have gone rock solid. Just one drop of oil on all shafts after clean and it will be a different machine.|
