38 Additional Information
Worn Video Heads
If your video TV displays a poor picture after you clean the video heads,
you may need to replace them. Consult your dealer or the Sony Service
Center nearest you.
Check the Video Heads after 1,000
Hours of Use
A video TV is a high precision machine. It must record on or play from
magnetic tapes on which the image signals from the colour TV or the
video camcorder are recorded.
The video heads or mechanical parts for transporting the tape are
contaminated or worn after extended use. You should have your video TV
checked after each 1,000 hours of use.
About Moisture Condensation
If the unit is brought directly from a cold place to a warm place, moisture
may condense on the video head drum. If this happens, the tape may stick
to the head drum and it may be damaged or the unit may not operate
correctly. To avoid possible damage caused by moisture condensation, be
sure not to leave a cassette inside the compartment when the unit is not in
use. When bringing the unit from a cold place to a warm place, wait for
about 10 minutes before operating it.
If the tape operation buttons do not work due to moisture condensation,
leave the unit for more than one hour with the power on.
Note
Do not use a commercially available
wet-type cleaning tape, as it may
damage the video heads.

Video Head Cleaning
When playback pictures are noisy and hardly visible, or when no picture
appears, the video heads may be contaminated. In such a case, clean the
video heads using the V-25CL video head cleaning tape (not supplied), or
ask Sony service personnel to clean the video heads, with this service there
would be a standard charge.
