How to get rid of groud loop noise from dish ?

Simple: attach one end of a wire (maybe with an alligator clip) to the outside sleeve of the satellite TV coax cable (where it enters the receiver) and ground the other end. You can also buy a Radio Shack ground block for cable TV that has a little screw for connecting such a wire. don't spend more than $5 on this problem.

I have EXACTLY the same problem with my TV and Sony DVP9000ES. I need to read this in more detail - at least you know you're not the only one, pal :)

I'll be damned! Pal Do what Bob Bundus said. It's cheap and fast and WORKS!
I also had this horizonal line floating on the TV thing, too and THEY BOTH ARE FIXED NOW!
Believe Bob when he says use a cable tie. The connection on the coax needs to be tight for it to really work. To test it, push hard and you'll see it goes away. I had to take the cover plate off to get a good fit on house ground, for now.
THANKS, my Friend! U DA MAN!

happy to be of service, per usual...
Simply use a clean (no oil residue) wire brush on that coax shield to scrape away the oxidized metal for a better connection.

Pal, did you try it yet?

I tried Bobs fix but no dice. Still have the noise. I tried all sorts of filters(including ground blocks), they work for cable but the dish signal will not pass through. My house has aluminum wire,I wonder if that is a problem.
