Video head cleaning
Video head clogging
The video heads are meant 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, DVD/VCR must 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.
