VIDEO HEAD CLEANING

VIDEO HEAD CLOGGING
The video heads are the means by which the TV/VCR reads the picture from
the tape during playback. In the unlikely event that the heads become dirty
enough to be clogged, no picture will be played back. This can easily be deter-
mined if, during playback of a known good tape, there is good sound, but no
picture (picture is extremely snowy). If this is the case, use a high quality head
cleaning system or have them cleaned professionally.
VIDEO HEAD CLEANING
Video head cleaning is needed when the playback picture becomes unclear. This signifies that the heads are getting
dirty and can occur when playing poor quality or damaged tapes. If the heads require cleaning, use a equivalent high
quality chemical non-abrasive (wet) head cleaning tape or have them cleaned professionally. If playing a head
cleaning tape in the VCR once does not improve the picture, play it several times before requesting service.
DO NOT ATTEMPT TO CLEAN THE VIDEO HEADS OR SERVICE THE UNIT BY REMOVING THE TOP COVER.
•
NOTES: Video heads may eventually wear out and should be replaced when they fail to produce clear pictures.
•
To help prevent video head clogging, use only good quality VHS tapes. Discard worn out tapes.
