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.
