Check the picture and if the above problem persists, repeat cleaning. [a] [b] [c] 206 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.
