NOTES: •
DO NOT ATTEMPT TO CLEAN THE VIDEO HEADS OR SERVICE THE UNIT BY REMOVING THE REAR COVER.

• To help prevent video head clogging, use only good quality VHS tapes. Discard worn out tapes.
Video head cleaning
Video head clogging
The video heads are the means by which the unit 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 unit checked by qualified service personnel.

DEGAUSSING SYSTEM
This television has a degaussing circuit that will clear up color distortions on the TV screen that
are caused by any excess magnetism which happens to get too close to the TV. This circuit is
designed to operate once when the set is first plugged in. If minor color distortions are seen in
some locations on the screen, please unplug the TV for approximately 15 minutes. When the TV
is plugged back in, the degaussing circuit will operate once to clear up any color distortions.
Repeat this procedure any time the TV screen is accidentally magnetized, or when the TV is
moved or relocated.
