Re: video Playback Sound but no picture

Sounds like the recording and playback heads are dirty. When was the last time you cleaned the heads? If you haven't, buy a Video cleaning kit which are cheap these days and run it through a couple of times. See if that clears it up.

No images but records sound

To start ensure that you removed the cover from the lens.
Also remove battery and put it back in place to reset the camcorder.

If you get only sound on playback, connect the camera to a computer or TV, or play the tape on a different camera. If you get picture in there, then the camcorder is recording, but the video playback does not work because of a faulty LCD display.
If when you play back the movie on a different camera, or using the compute you still get no picture then the camcorder is faulty.
Faults that can cause black screen can be:
Lens problem. Faulty CCD sensor. Faulty controller board.
All this faults are not easy to diagnose and fix, if there is a fault , then it is better to take the camera to a repair shop.

No sound on playback

The S-video cable carries picture only. You need to also hook up RCA audio cables from the camcorder to the TV

Playback on PC has no sound

Are you playing the video back through the camcorders utility ? Sometimes by clicking on the file through windows explorer you will get the picture but no sound, this happens for the Sony camcorder but is fixed by running the playback through the motion picture browser application supplied with the camcorder.

Black screen when recording but records audio.

This model Sony has a known defect in the CCD image sensor which will cause the camcorder to record a black picture or smeared picture. When played back, the sound will be fine but the picture will be black or smeared. Your older tpes you made before will be just fine when played. Sony is fixing this for free, postage paid. Go to their site, go to the support area and put in this model and you should be able to find the notice for this problem. They will send you a paid UPS shipping label to print out. You'll have your camcorder back working in about 2 weeks! :) Mike63

No sound when playing back video

I had the same problem. Try this: open the LCD screen so that you can access the playback buttons.Make sure camera is in playback mode. Press the "menu" button. Select "narration" . Switch narration to "off" .Now you should hear the recorded audio when your tape is playing.

PLAY mode only. * You can play moving picture images on the Memory Card. * To hear sound during MPEG4 playback, you must hook up to a PC and listen to the PC's speaker.
