Checking the video heads every 1000 hours
A VCR is a high-precision piece of equipment that
records and plays back the picture on a magnetic tape.
In particular, the video heads and other mechanical
parts may become dirty or worn. To maintain a clean
picture, we recommend maintenance every 1000
hours, even though the conditions of use may differ
depending on temperature, humidity, dust, etc.
Cleaning of the video heads
If the video heads are contaminated, the pictures
cannot be recorded properly or the playback pictures
become noisy. If the following phenomena occur, use
the cleaning cassette (supplied) to clean the heads.
• Square-shaped noise appears on the playback picture.
• A part of the playback picture does not move.
• The playback picture does not appear on the screen.
Symptoms caused by contaminated video heads
Normal picture If these pictures appear on the
screen, use the cleaning cassette.
To use the cleaning cassette
Refer to your cleaning cassette's operating
instructions.
After prolonged use, the video heads may become
worn out. If optimum picture quality is not restored
even after you have cleaned the video heads with the
cleaning cassette, the video heads may have worn out.
In that case, you have to replace the video heads with
new ones. Please consult your Sony dealer.
