Dirty Video Heads
When the video heads have become
clogged with dirt (dust and tape coating
particles),
• mosaic-like noise appears on the
playback picture. (See illustrations above.)
• playback pictures do not move.
• during playback, the whole screen
becomes blue.
Using a Cleaning Tape (Commer-
cially Available)
Available mode:
Tape Playback
You can clean the video head with a
commercially available cleaning tape.
Notes:
• Excessive use of the cleaning tape may
cause damage to the video heads. Please
read the instructions accompanying the
cleaning tape carefully before using it.
• The fast forward and rewind functions cannot
be used when the cleaning tape is in the

with dirt soon after cleaning, this might be
caused by a damaged tape. In this case,
stop using that cassette immediately.
