VIDEO HEAD CLOGGING
>
Snowy Picture
In the unlikely event that the video 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 unit checked by qualified service personnel.
Note: We do not recorimend that you attempt to clean the video
heads yourself.
