Ground hum from set top box...

[Ax-man]

I've moved my equipment into a new dedicated room and have a heck of a nasty ground hum from the RG6 coax going into set top cable box. All other equipment is perfectly fine but whenever I connect the coax for the cable into the set top box I'm getting a nasty ground hum...I am using component and also connected R/L audio as well as coax, no matter what cable I connect I'm still getting the ground hum.

I grounded the outside cable splitter to an 8' grounding rod as well as tried grounding the chassis of the set top box to the ground plug on the back of the Monster power conditioner. Still hums.

What do I need to try next?

Try one of the ground loop isolators available at radio shack. I remember seeing great praise for the Jenson Isolation Transformer as well.

The ground rod also has to be wired to your house ground rod... that is probably where your ground loop is coming from.

It is also not to NEC code.

I've since connected it to the main house grounding rod and am still getting the hum, I'm thinking there may be another issue regarding electrical.

If you disconnect the cable from the STB or at the wall does the problem go away?
