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.
How to get rid of groud loop noise from dish ?
I just bought a sony 9000 DVD player, but when I connect the component connecters to my tv I get ground hum in my stereo system. I tried filters on the incoming coax, but the signal from direct tv will not pass through it(it did get rid of the hum). Does anyone have any suggestions?
