Video interference: how do I stop it?

[flylock shox]

I thought I'd left these problems in the 90s when the VCR went out the window (I actually threw it out the window. Hit a kid. Felt bad. Lesson learned).

Anyway, now I've got a blu-ray player, running into a receiver, running into the TV. A surround speaker package also goes through the receiver.

Whenever I play a DVD, there's a light vertical band that rolls across the screen from right to left. It cycles about once a second. The band doesn't obscure the picture, it's just like it overexposes the part it's passing over, like someone scrolling a narrow flashlight across the screen.

I thought it might be magnetic interference from the speaker cables, so separated them from the video cables - but no luck. I'm out of tricks. So I'm doing what any sane person would do: consult a hockey forum.

Has anyone ever had this problem? More importantly, has anyone ever fixed this problem?

Any ideas would be greatly appreciated.

My first thought would be to check out your TV settings if you haven't yet tried to optimize it.

Maybe it's your receiver? Have you tried running directly from your Bluray to your TV?

What you describe is a grounding loop issue.

Don't get too tied up in the technical aspects in these articles. Read them to be sure they describe what you are seeing then search around a bit to see if there is an easy solution to your specific situation.

I was worried about that. But then, the old DVD player was okay running through the receiver. Of course, that was via a different port.

I'll give Bobblehead's articles (thanks Bobblehead) a read and then see how I fare. Hopefully I can kybosh this problem without too much rewiring or equipment hullabaloo.
