Solution to a ground loop problem

Good luck with the cable company....been there, done that and no satisfaction whatsoever. Stay away form the "quick fix" like the cheater plugs and be sure to consider a product that will not weaken of your cable signal.

Keep trying. On the 3rd service call, I finally got a tech who, while first spouting the company line that ground loops due to an improper cable ground are unknown, listened to the setup and what I had to say. He then said, "What the heck! It will take me 10 minutes to redo the grounding." After he did, I proved to him that it was effective: No more hum.

I had the same problem you have and I solved it with the Mondial Magic Brick as Dollysowner did.

I gave away my Mondial Magic Brick when my ground loop was cured. The Brick had problems with the DMX signals on my cable.

Problem solved! Twofold solution: Replaced the grounding cable at the cable box which solved 50% of the problem and then I stopped by a local highend AV installer and for $5 they gave me a DTIS IS-07 Isolation XFMR 100KHz-IGHz which is an adapter which goes between the cable box and the cable. No hum. Sound like a solution? What do you think?
