Head Cleaning - Hitachi 20VR4B Operating Manual

HEAD CLEANING

HEAD CLEANING
The heads are tiny mechanisms in the TV/VCR Combination that pick up the video signal
as a videotape passes over them. In time, a residue of electromagnetic dust builds up on
the heads because of contact with the tape. This dust interferes with the signal being
picked up.
Your Hitachi TV/VCR Combination automatically cleans the video heads whenever a
cassette is loaded or ejected and when a cassette is already inside the TV/VCR
Combination when you turn the power off. It also self-cleans during fast-forward and
reverse play. You will hear a mechanical sound during auto head cleaning.
Even with the auto head cleaning system, dirt can build up on the heads. If the picture is
blurry during playback, or is occasionally interrupted or blanks out, try playing different
cassettes to see whether you get the same picture problems.
If the picture problems persist, the heads may need to be cleaned professionally. Consult
your TV/VCR Combination dealer for the name of trained service technician near you.
