Video head cleaning
Video head clogging
The video heads are the means by which the DVD/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 determined if, during
playback of a known good tape, there is good sound, but no
picture (picture is extremely snowy). If this is the case, have the
DVD/VCR checked by qualified service personnel.
NOTES: • DO NOT ATTEMPT TO CLEAN THE VIDEO HEADS OR SERVICE THE UNIT BY REMOVING THE
REAR COVER.
• 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.
