Well then!!!!

I also have a problem with a "ground loop hum" since adding the 7500. It seems from many of the posts I've read, the Jensen Transformer has been successful in the case of those who have Cable systems. I have DirectTV and when I tried the Jensen Transformer (VRD-1FF) it simply cut off the signal altogether...obvioulsy not compatible with Satellite bandwidths. Any suggestions for a similar device that works with Satellite feeds?

The cable guy came out and looked very confused when I explained the problem to him. So I brought out the manual and read it word for word highlighting the solutions provided in the manual. He still didn't seem to know what to do. He asked if I had any video problems and I said no. He said putting in a ground loop isolator usually fixes video problems but he had never heard my problem before. I suggested he try the isolator for this problem too. He didn't seem like he really wanted to do it but did it anyway. Lo and behold the problem is fixed. He still looks dumbfounded. I explain to him that it's probably the same issue that causes the video and audio problems.

I sometimes wonder about the techincians. Atleast my problem is fixed.

congrats getting your problem fixed. While the cable guys are pretty knowledgeable about cable hook ups.. they often lack a real electronics background.
