I recently added a second dish to my home theater to be able to receive HBO-HD and when the installer hooked everything up I now how a steady hum that I can't rid of. I think the problem is coming from this small powered device that he hooked up. It's called a Dish VideoPath Power Inserter. He has it hooked up between the dish receiver and from the wall jack. It is a powered device and when I unplug it I lose all satellite signal. I think the reason I have this device is because he is using a SW64 switch. I have been trying to fix this and it's driving me nuts. I am running the coax through my Monster HTS2500 power center and it's doing nothing to fix the issue. Is there anything that I could do or use to fix this nasty hum? I am thinking of calling dish network back and see if they can fix it. I have read about other people talking about hearing a hum and usually they call it a ground loop hum. But it's usually when they add a power amp. So I don't know if I have that issue or not. All of my devices are plugged into my monster power center and the power center is the only device that is plugged into the wall. Did anyone else every have or heard of this issue? I appreciate any help that I can get. Thank you.
