I hate dealing with ground loops and they seem to pop up again and again.  Every time I add or change a component of my home theater the hum returns.

The easy one to solve is the cable line which is the main source of the hum.  Just visit parts express and buy a Dayton VIT-1 Video Isolation Transformer.

After installing the Isolation Transformer the hum will be weaker if not gone.  If it still exists there is some detective work to do.  My father found a great article describing how these ground loops are created and how to fix them.  It is a riveting tale of voltage potential and Ohm’s Law.
