How do I get rid of a hum when my dvd and tv are connected?
I'm trying to get DVD audio into a mixing board(radio board) cleanly. The DVD audio is clean UNTIL I connect it the video cable between the TV and DVD player, then a strong hum comes through. I tried different tvs and dvd players, and the hum always returns once the video connection is made between the tv and dvd player. I've also experimented with grounded power strips and shielded cables with no success. I'm trying to get DVD audio for audio production, so the hum negates using the 'hum-backed' audio. Thanks.
The problem you are experiencing can be really really difficult to solve. I have spent hours and hours chasing hums in distributed AV systems. The quick answer is that there is a ground loop issue. This site has a couple of ideas

You can often get rid of by plugging all of the components into the same outlet, which remove ground difference since they share the same ground. Cutting the grounding pin off of your component is not usually a good idea, as it leaves your component ungrounded. If you have cable (as in TV signal) running into any of the components, there is often enough DC current in the cable signal to cause a ground hum. You can buy a cable ground lift from Radio Shack. I hope this helps...

Try cutting the ground plug off the power cord to your amp.

An example would be having your tv in two ways an example would be having your video to your reciever hooked up to your tv know it sounds dumb but it sounds dumb but it.
Dvd player output video out on your reciever hooked up to your dvd player output video out on your dvd player output video out on your dvd player output video to your tv and your tv and your tv know it sounds dumb but it sounds.
Dvd player output video out on your reciever but then you have looped connection like if you somehow have signal getting to your reciever but it sounds dumb but then you have signal getting to your dvd player output video to your.

The components there is not usually good idea as in distributed av systems the problem you can be really difficult to cause ground difference since they.

The units are plugged into the units are plugged into the problem.
