Video Head Clogging
The video heads record and playback pictures and sound on
the video tape. In the event that they become dirty you won't
be able to do a perfect recording and the playback picture will
be extremely snowy. Also, keep in mind that a poor tape
quality and a damaged cassette may contribute to the rapid
accumulation of dirt on the heads.
Automatic Head Cleaning System
The Automatic Head Cleaning System cleans the video heads automatically when a cassette is inserted and ejected
to prevent dirt from accumulating on the heads. However, manual head cleaning is needed if the picture on playback
is still unclear although the picture on program is normal. This failure signifies that the head is getting dirty and can
occur when playing poor quality or damaged tapes. If the heads require cleaning, use a high quality head-cleaning
cassette or have them cleaned professionally.
Attention:
Video heads may eventually wear out and should be replaced when they fail to produce clear pictures even after
having been carefully cleaned.
