During playback it is not reading the DV or showing the video. This is new. Also, previously I have the problem of blue stripes showing up on the playback.

try camera menu (change some settings )

The v900 has some years on it. It will need the heads cleaned ,possible torque adjustment or replacement of the video drum unit. To clean it is only $40 at Larry's electronics [email protected]

Blue stripes in playback is an indication that you need to clean the heads. A Panasonic cleaning tape should work fine.

Your tape has a small latch on it that closes to protect from recording or eraser and opens to allow for playing or dubbing. Slide it open and see what happens.

first u put clean casset and try . again it coming then u chaing video head

kindly rate me if ui have helped u !

i hope ur problem gets solved

If the heads become dirty, “NEED HEAD
CLEANING” appears during recording. During
playback, moreover, the following symptoms
appear.
≥Mosaic-like noise appears partially or the
sound is interrupted.
≥Black or blue mosaic-like horizontal stripes
appear.

When normal playback cannot be performed
even after the head cleaning
One possible cause is that normal recording
could not be performed because the heads were
dirty at the time of recording. Clean the heads,
and perform recording and playback again. If
normal playback can be performed, the heads are
clean. Before an important recording, be sure to
conduct a test recording to make sure that normal
recording can be performed.
≥If the heads become dirty soon after cleaning,
the problem may be the tape. If so, try another
cassette.
≥During playback, the picture or sound may be
interrupted momentarily, but this is not a
malfunction of the Camcorder. (One possible
cause is that the playback is interrupted by dirt
or dust that momentarily adheres to the heads.)

try a hard reset

I covered several threads that recommended buying a Mini DV cleaner and running it up to 4 times. They also suggested to change to change your video tape as it may have been the cause of the original problem.

These solutions may have worked for many but not me. My camera was becoming progressively worse. It went to blue bars and no sound to no picture at all...just blue. After using a cleaner 4 times I became frustrated to the point I was going to buy a new camera.

However, with the camera still playing, I did the typical guy thing and rolled up my fist and gave it a good hit along side of it. Remarkably it went back to just the blue bars. I hit it again and it went back to a perfect picture. I'm not saying this will work for you and hitting it too hard could make things worse but I was at a point where I didn't care any more and took a chance that paid off.
