    Hum or Hiss?

    Disconnect all video sources, and start adding them back one at time - and you'll find what is causing your ground loop.

    Cheers,

    Yup, sounds like a cable is a bit out of whack to me.

    Russ is right with the fix.

    just in case this ever happens to me, what do you do once you've actually found the source of the noise?

    Replace the faulty source component, if it is a IC, if it is a ground loop problem, then you can get an inline isolator to curb the noise. This is probably not the case as from what I can tell you are not running separates. It could be your cable system coming in, in that case you could also get a isolator......This can be extremely frustrating, and can wreck your weekend, especially if you have a ridiculous amount of gear to try and troubleshoot and isolate the problem. I found that it was my parasound amp causing the hum, a difference in potential in all the other components in my line up, is what I gathered. So I got a Jensen Transformer Isolator (Model CI-2RR ), bought more IC's to connect the Isolator, and then I "enjoyed the silence".....

    good luck

    A good power supply will fix the power source hum, I'd bet it is in the IC's somewhere. I've had this issue twice, both times it was a bad IC
