Question about Sony Handycam DCR-TRV310 Digital Camcorder

Playback is not working correctly. The picture is choppy as is the sound. I tried cleaning the head with cleaning cassette but didn't improve the problem. Possible tracking issue? Thanks

    Thank you for your reply - How would I adjust the tracking and what are tape guides? Does this require a trip to a professional or is it something I can do. If it is something I can do are there any directions on how I would adjust the tracking? Your help is appreciated.

This is hard but worth a try. Take a small toothbrush shaped brush and, with the cassette door open, clean the tiny slots at the base of the tape head. These slots are actually the tape read and record heads, the rest of the cylinder just creates an airspace under the tape in order for it to travel smoothly. Tape head cleaning cassettes are incapable of cleaning this area. Thank you, Dana

Hi,
If tape drive guides have not been tried to adjust the tracking then it is weak video head problem and video head will be replaced.
And if tape guides have been adjusted to correct the problem then yes, its tracking issue.
Readjust tape drive guides and check tape threading mechanism should be cleaned and smooth.
Thanks.

    Tape guides are two arms that takes tape around video head and set tape path so to video head can read written data on plastic tape around it while spinning very fast.

    It is professional person job to adjust it with special tools like v-8 alignment tapes, oscilloscope etc.

Canon gl1 camcorder dead pixel and artifact when


Hi there,

I know this camera well !

This is likely to be your heads, but you need to be made aware of the following:

1) MiniDV cassette

The quality of your cassettes should first be considered:

Panasonic, Canon and several other brands use what is called "Dry Lubricant" cassettes. For this reason, you should AVOID at all costs, any cassette made from a manufacturer whose cameras use Wet Lubricant type cassettes. Unfortunately, this means you should AVOID SONY cassettes (as Sony cameras use the WET lubricant system).

Dry type cassettes also cause less wear on your heads.

I would highly recommend you use only Panasonic PQ (Professional), SQ (Studio) or MQ (Master) quality cassettes.

(PS: I use these Dry type cassettes on my Canon Pro Camera)


2) Camera HEADS

As stated in above (re the cassettes), if you have inadvertantly used a WET type cassette in your camera (i.e. Sony or similar), have been using old cassettes or debris/dust has entered the compartment, then there is a high probability that some microscopic contaminants may have fouled your heads.

If so, your heads will require cleaning.

The good news is, Panasonic have a MiniDV Head Cleaning cassette (DVMCLA) which can be purchased for around $8 - $15. (try Amazon.com).

If you choose to use this cleaning cassette, it is EXTREMELY IMPORTANT that you only run the cassette for a max. of 5 seconds ONLY, for each clean (and no more than 10secs, as using this cassette longer than stated, can cause wear). Then, try playback of your old cassettes to look for improvement. Cleaning is only necessary, if you experience drop outs on dry type cassettes, or pixelating of picture playback.

If this head cleaning process does not resolve your problem, then you will require professional assessment.


Good Luck !

The DV tape is totally macroblocking during playback. Is this an indicator of dirty heads?

Blue Screen or Pixelated on Playback


Check Canon's Website. There's a known problem with video chip on several different models...including zr80...a loose connector from the CCD.

I know what I'm talking about because I just got one fixed...for FREE.

Sony TRV510-playback, audio choppy, image isn't clear


I was having the exact same problems, and I read a post on this website somewhere recommending that I just record a few seconds of video on a blank portion of tape and then the camera should start playing video normally again.

I tried it, and IT WORKED!!

Choppy recording and playback


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.)
