Question about JVC GR-DVF31U Digital Cybercam GRDVF31U Camcorder

1 Answer

Recordings are pixelized

Playback is ok, New recordings have large amounts of pixelizing. Tape head cleaner cartridge did not affect the symptoms. Does it sound like professional cleaning or demagnetizing is needed or is it probably more serious?

Thanks, Tm

Re: Recordings are pixelized

Never use tape head cleaners, I suggest just use new blank tape and I recommend TDK minidv tapes, new tapes already serves as video head cleaner. If the problem is still there, manual cleaning is needed or it is possible that your video head is worn out already, you need profix then.

Pixelation and sound drop out

This case sounds like really dirty picture and sound heads in camera and tape kept sticking so exposure was on each part of tape too long.
Keep camera heads shiny and clean by buying camera tape cleaner.

Recording very snowy and blurred.

If recordings are only blurry and snowy on playback on camcorder, but are OK on a different camcorder or on computer, then the problem is a dirty magnetic head. Use a mini-dv head cleaner tape. If recordings are blurred even on pc or on a different camera, then there is a fault. Faulty CCD sensor, faulty digital board, problem with internal ribbon connector, and dirty or defective lens assembly can cause this kind of problem.

Canon XL2 wont record or playback tapes - grey

Sorry to hear your situation, usually when serviced by a technician, head and tape path is cleaned and adjusted. During use you will encounter pixelation problems occur and most case tape cleaner should resolve the problem. Your condition is where if all the system is ok and have a heavy clogging on the heads, requires technician to clean each head manually to bring it back. so look for a camcorder repair facility locally and get cleaned. If you cannot find one, the service is provided for around $100 at www.camerarepairjapan. Good Luck

Pixelated recordings

clean heads and tape transport with head cleaning tape, worked for me. had to run the tape 3 times at 10 second intervals with a 30 second cool down between runs. Dont clean for more than 10 seconds at a time as the cleaner tape heats up head and will fuse dirt onto head if overheated.

Bad playback quality

Some possible cause of lines, noise or pixelation during playback are: 1. Dirty heads on the recording machine. If the heads were dirty at the time of recording, the dirty heads didn't record a strong enough signal on the tape. The damage is done for this tape and recovery is unlikely. Best advice here is to use only premium grade new tapes and keep your camcorder clean by occasionally running a cleaning tape. 2. Physical tape damage. Any distortion of the tape will result in mistracking and subsequent loss of data. 3. Built up oxide deposits or other debris in the guidepost corners can also result in tape edge damage. Keep your machine clean! 4. Improper tape storage - Even short term exposure to high temperatures over 130 deg f. can permanently damage the tape. The black cassette housing readily absorbs the sun's infrared rays and internal cassette temperatures can soar even if left in direct sunlight on just a warm day. It doesn't take much heat to slightly distort the plastic shell or ruin the tape contained within. * Try other tapes to ensure the problem lies within the tape and not the camcorder. * If the problem becomes apparent on all tapes, try a head cleaner. After cleaning the heads, the tapes may not play cleaner if the recording was done while the heads were dirty.
