Symptoms caused by contaminated video
heads
When the video heads are dirty, clean the video
heads using a Sony video head cleaning cassette.
If a Sony cleaning cassette is not available in your
area, have the heads cleaned at your nearest Sony
dealer (a standard service fee will be charged). Do
not use a commercially available liquid type
cleaning cassette, as it may damage the video
heads.
