Well HO-HO-HO thank God Christmas came a little early to my house. I spent numerous hours trying to fine this annoying hum, which only recently developed in my Home Theater....without success. Ready to throw in the towel I remembered a friend of my who is an electrician. I called him on Friday not thinking that he would have the time to come over that day but I thought I could set up an appointment for the following week.
His Christmas present to me was that he came over on Friday and spent five and half hours locating more than one problem. I am making a list below for everyone to out in there notebooks if anyone would have a similar problem. I thought that it might be helpful.

First was the outside grounding pole. I had one but with two grounding wires corroded. One was for the ciruict breaker box and the other for my home theater.
Second was that there was no ground wire connected to the incoming cable lines that were connected to two splitters.
Third was the cable bow itself. As soon as we connected the antenna the hum was back.
So we elimantated the cable box until the cable service comes to the house on Wednesday.
Fourth was the seperation of all Romax cables for a distance of six inches.

All of these problems were part of or a single issue of the annoyng, unrelenting hum.

I hope that if someone out there is having an issue with a hum that these facts help.

MERRY CHRISTMAS TO ALL!!!!
