I have a Canon ZR90A and started noticing horizontal gray lines displaying across the screen when it plays back. What is causing this?

The most common cause of horizontal lines during playback is dirty heads/tape path. If you have a head cleaner tape, try playing it for about 5 to 10 seconds and then try your tape again. Repeat as necessary. Try not to run the head cleaner for long periods of time because you may wear down your heads quicker (cleaning cassette is somewhat abrasive). If you do not own a head cleaning tape, I highly recommend purchasing one. Sony (in my opinion) makes the best miniDV head cleaning cassette. We use this brand in our repair shop and they last for years. I have posted a link to the particular tape I am speaking of. Your local camera/camcorder shop may have these for sale.

Hope this helps you.

Grey lines

I have had this problem myself, and it is nothing more than a head cleaning issue, from my experience. Sometimes, when a head cleaner will not work, the camera requires proper maintenance. The problem arises through long pauses, and over time. A suggestion for better use perhaps, would be to not pause tape for too long when playing back. Based on personal experiences.

Gray horizontal lines across the screen in playback is symptom of dirty / clogged video head and you need to use good quality mini-dv video head cleaning tape to clean video head.

Lines across screen on playback.

A Q-tip should never be used to clean a video head.  Unfortunately they can pull the tiny head out of alignment.  I believe this is your problem and the repaid may be more costly than a new purchase.

Canon camocorder thick gray lines on ever recording

Canon support was of no help. They ****! To fix the problem this is what I figured out.

  1. Before you start filming what you want record or just advance the tape 10 secs or so.
  2. Record/ video whatever you planned.
  3. Now when the thick grey lines come up on play back don't freak out.
  4. Simply rewind the tape to the beginning and record briefly in the blank portion at the beginning (careful not to tape too long as to tape over your intended recording).
  5. Rewind and play the thick grey lines should now be gone.
How did I figure this out just a fluke. No cleaning, no spray pretty simple. At first did not understand it but it works EVERYTIME for me. I'll deal with it until I get around to buying a new HD video camera and it won't be a Canon. Hope this helps.

On playback, the video has gray lines across it

Someone here recommended on another post to put the lense cap on & videotape the blackness in a quiet room for 5-10 mins. I tried this as a last resort & it worked. When I played back the tape, no more skipping or gray lines. I had 4-5 SOLID gray lines with skipping video & audio in between on every tape I put in. The person who helped me solve this said: "the speed isn't linked with the last time you recorded on it. Frames have an A/B part to them. If A is hitting B instead of A, a line appears. I would try the head cleaner first, then blacken your used tape (keep lens cap on and record in a quiet room) and try that."
My camera is a Canon zr80 digital camcorder. (Called Canon, they had me reset it & then recommended sending it in).

Black or blank screen

your older recordings will only play on a pal monitor / tv ; if the camera video is ok now ? your tape heads may be dirty , wearing out - or both ; try a cleaning tape first but - do not rewind cleaning cassettes , or the old grime will be put back on the cleaned heads and guides ;
