Cleaning the video head
To ensure normal recording, clear pictures and sound, clean the video head. The video
head may be dirty when:
Mosaic-pattern noise appears on the playback picture.
Playback pictures do not move.
Playback pictures do not appear or the sound breaks off.
The x indicator and “ CLEANING CASSETTE” message appear one after another
or the x indicator flashes on the screen during recording.
If the above problem, [a], [b] or [c] occurs, clean the video heads for 10 seconds with
the Sony DVM-12CLD cleaning cassette (optional). Check the picture and if the above
problem persists, repeat cleaning.
If the video heads get dirtier, the entire screen becomes blue [c].
Note on the video head
The video head suffers from wear after long use. If you cannot obtain a clear image
even after using a cleaning cassette, it might be because the video head is worn. Please
contact your Sony dealer or local authorized Sony service facility to have the video head
replaced.
Cleaning the LCD screen
If fingerprints or dust make the LCD screen dirty, we recommend using a cleaning cloth
(supplied) to clean the LCD screen. When you use the LCD Cleaning Kit (optional), do
not apply the cleaning liquid directly to the LCD screen. Clean the LCD screen with
cleaning paper moistened with the liquid.
