Jvc Camcorder Lines Troubleshooting







JVC's camcorders are prone to the same sorts of problems as VCRs.


JVC was one of the first camcorder makers and started selling camcorders in the early '80s. Early camcorders used analog tape---similar to VHS cassettes that were used in time-shifting video cassette recorders. Early JVC camcorders are prone to the same sorts of problems as VCRs. Tape heads can become misaligned and dirty, ultimately wearing out, and lines can appear with early JVC camcorders. Lines on a JVC camcorder can be corrected by following some troubleshooting steps.


Instructions








1. Change the contrast between the subject and background if white, vertical lines are evident on playback when filming bright subjects. White, vertical lines are caused by a lack of contrast. Reduce contrast---move the bright subject to a brighter background or lower the subjects' brightness.


2. Adjust the tape tracking on the JVC camcorder when playing back if the recording appears to have horizontal, white fuzzy lines. It's caused by head and tape alignment. Look for a tracking control. It's often on the remote. Adjust the tracking on playback until the lines disappear.


3. Remove sources of environmental interference that can cause lines. Turn off microwaves, Wi-Fi routers and florescent lights to see if the lines disappear. Isolate the camcorder by moving it away from anything electrical or motorized and see if the lines go away.


4. Clean the tape heads with a commercially available tape cleaning cassette if lines still won't go away on the JVC camcorder. If tape-head cleaning won't fix the problem, the tape heads may be worn out and need replacing. You may find it cheaper to discard the existing camcorder and invest in a new digital camcorder that uses solid state technology, rather than tape.
