Hi

Grainy pictures on pre-recorded tapes played on your VCR is a symptom of either

1) Dirt and static build up on the playback head inside the VCR. (see below)

2) A fault within the playback head itself. (will require service replacement)

3) Tracking control improperly set - (This can be adjusted either via the menu options on your VCR or using left and right tracking buttons on the front of the VCR)

4) An improperly aligned playback head (will require service adjustment)

4) An improperly tuned TV - retune TV to video output channel (if your VCR is connected via SCART this does not apply)

As you have already used a head cleaning tape with out any success the only other option to remove stubborn build up is to open the VCR and clean the head directly with an alcohol cleaning solution and a soft chamois tipped stick. This will often resolve the issue but you need to be careful during this process.

A very good How To Clean Your VCR Heads can be viewed at this link http://hometheater.about.com/cs/vcrs/ht/vcrheadcleaing.htm

As always when opening any electrical appliance - ensure it is disconnected from the mains supply to avoid risk of electric shock.

If you find this problem occurs only with pre-recorded tapes and the VCR plays back its own recordings well - this is a strong indicator that the head is misaligned as per point (4) in my answer.

Hope this helps. Please remember to rate my answer. Many Thanks.

My canon camera seems to work fine in record mode. The LCD shows the video and the timestamp, and tape is moving. Yet in playback mode no matter what Tape I use (even if I know the tape has video on it)...


The playback head is dirty. Insert a brand new tape into the drive and perform a record, through the entire tape until it reaches the end. Then play a pre-recorded tape.

Play back poor now Camcorder does not record


The head is dirty or bad - insert a brand new blank tape in the camcorder and perform a record through the entire tape without stopping the process until it finishes the record all the way through - this should clean the heads. Playback a pre-recorded tape. If it plays back ok then attempt an actual record. If unsuccessful, then the heads are bad.

Blue screen on lcd screen


The playback head is probably dirty and cannot show the picture - the screen is blue. Run a blank tape in the tape drive and execute a record all the way through the tape. Then play back a pre-recorded tape to verify it plays back ok.

No audio and video appears after recording


The blue indicates a lack of video signal. Try playing a pre-recorded tape to see if the unit will "read" a tape. If yes, then the record section of the VCR needs attention. You can ry cleaning the heads as well. If you are not getting sound either, then there is a different problem perhaps the incorrect input is being selected? It is possible that the internal switching is not happening correctly. Without seeing the unit and poking around inside, I can not say for sure, but try the cleaning and update this with any changes in symptoms.

Sony 8mm camcorder will record sound but no video


Since it is playing the tape, the play head is ok. Now recording is done by recording heads so you may have a clogged heads or damaged recording heads. Try to clean the heads with head cleaning tape to see if it would help. 1. remove the tape and leave the door open. 2. using a canned air, blow out any dusts in the tape area. 3. run head cleaning tape for about 10 seconds and no more. 4. try the recording.. If this does not resolve, you may have a damaged or heavy clogged video heads. Take it to nearest video technician for a diagnostic. -James
