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 pic-
ture 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.
POSSIBLE SOLUTIONS
