Bars on video playback

[glen65]

Hello,
I am working with a Canon ZR80 Digital Video Camcorder.
I am getting solid horizontal bars running through the
picture during playback on the LCD screen. See pic below.
I cleaned the heads but it didnt help. Any ideas?
Thanks.

Strange... Sure looks like dirty heads on an analog VTR.

Try the head cleaning again. If you can't get it going, you may have to have a tech look at it. I killed the heads in my old Sony Hi8 cam just under normal use. And I've seen heads go bad in Pro BetaCam units often enough. Hope that's not it!!

Let us know what you find.

This problem is definately not due to head problems.

Could be induced hum, but it looks a bit too 'solid' for that.
Is the problem present on an external monitor / player?

Thanks for the response,
Ok first as “dnsey” recommended I hooked it to an external
monitor and it did the same thing. I decided to try another tape so I did and I got the same result “but” after about 10 seconds of play it slowly returned to normal and now the picture looks fine. I then went back and played the original tape and it looks ok too.

could be dry solder

I was thinking that.

In the TV shop, pictures like that meant oscillation somewhere, usually due to a bum bypass cap. Cold solder joint on such a cap can make one pull hair out
