horizontal bars in playback

by pntrmarc / February 10, 2009 8:38 AM PST

this is my 2nd camcorder and the 2nd one to develop horizontal bars in playback. Is this head alignment? Can I take it to an av shop to have it repaired? Canon told me it was not worth it to repair theirs after my using it less than 5 hours. This time it's a Panasonic PV GS 320. I've gotten more hours out of this but I can't buy a new camcorder every 6 months because this happens in all of them.
I started downloading this tape last week and it was fine. Now half the screen is horizontal blue bars

In fact it now does bars in playback on a tape which worked fine 10 minutes ago ! And I didn't drop it in the mean time. It has done this before at the start of a tape but always cleared up after a while.

Do you see them at the LCD or TV or both ? or at the computer monitor screen ?
Are the bars(or strips ?) uniform width, with one distintive color, orattrned strips of various colors ?

I'm seeing them on the monitor (LCD?) on the side of the camera. There are about 6 bands of equal size alternating the picture and solid blue bars. Thanks ahead of time. Any hope?

..if it came on suddenly (fine 10 minutes ago), and you are only seeing it on the camcorder monitor but not on the viewfinder, or output to TV, the fault is on the camcorder monitor and relected electronics. Have you tried the tape on another camcorder (which accepts similar tapes) ? Does it happen on every tape ? CANON seems to know about the problem.....

Miscommunication. It's in the viewfinder, I also get it in the software I use to download it.

Tape play fine ONCE...

... but afterwards, they always play with the bars showing ? For the whole length of the tape, or only at the replayed section ? This happens to all tapes ? Even with tapes recorded on other camcorders ? The bars seem to be "recorded" during rewinding or while playing for some time.... Try playing a new unrecorded tape for, say 15 minutes, rewind, then play it again -do the bars appear ?

Are these tapes being re-used?
by R. Proffitt Forum moderator / February 10, 2009 9:31 PM PST

Just in case that wasn't covered.

And are you the type that cleans their own gear? Did you clean the heads? Do you know how?

that came up once and I couldn't find the tape head cleaners locally. But these are absolutely solid bars, not the kind of noise one gets with a vcr when it needs cleaning.

Then do the tapes play in other camcorders?

-> You didn't answer my question about tape reuse.

I have 3 tapes, they've been reused but all 3 played yesterday, now all 3 show the bars.

Read carefully.

As this is a discussion forum and not tech support I hope you could answer the questions rather than wait for another post to ask again.

Just advice.

1. See if the tapes play on another camcorder.
2. Don't reuse tapes.

If you use the AV cables to connect to TV, do those bars show up ?

In reply to: yes know what is on the tape...copy restricted material ? Or self taken video ? It seems that the bars, being solid blue color, are put on automatically and intenionally afterthe first play... ?

good luck
by pntrmarc / February 11, 2009 8:24 AM PST

I took it in to a camera tech and he couldn't get it to screw up !! He said there's a drum with more than one pick-up and all it takes is dust or some other material. He said he doesn't recommend cleaning tapes because each time this happens they pop in the tape which is abrasive. He mostly deals with professional cameras but this sounds everyday common. I asked about using canned air to blow it out; he said there are springs which can become dislodged. He didn't charge me, I hope it doesn't become a regular trip.
Thanks for your attention, Marc

This is warning not problem..
by ioannisgr / October 21, 2010 4:50 PM PDT
In reply to: good luck

The problem was fix like this: in the same tape was appear the horizontal lines record 1-5 seconds if you have space on the tape if not use other tape and the lines disappear.
This problem i have some times was use my camera in the record type without tape only for transfer video with firewire or usb cable in to my pc.
Is not problem but warning the user was some days to record using the camera.
I hope my answer helps to solve the problem
