Hmmm. It does mean that grounding is probably at least part of the problem but I'm not sure what your next step should be. Any ideas, folks ?

Hi. Did you try replacing the screw in the subwoofer after you disconnected the TV cable? I had a ground loop problem with my EP500 caused by the cable TV. I ended up buying a Jensen Isomax SUB-1RR between my reciever and the sub. It solved the problem. The isomax was about $100. This fix should work no matter where the ground loop is. You can also get a transformer to go between the TV cable and the cable box which is cheaper. I was afraid of messing with the quality of my TV reception so I went for the SUB-1RR.
My first post.

dude, i just went through the same thing last week except that my seprate amp had the hum and not my sub. I will say it is a ground loop and you should pick up an isolation transformer to break the ground loop. the guy who posts the links should be here shortly to show you what i mean. don't waste your time unplugging everything in your house like i did, i still had an audioable hum with my cable and other equipment unhooked. however i inserted the isolation transformer and it took care of the hum. the part is only 10 bucks so if it doesn't solve your problem it won't be like you spent alot of money. check out the thread tittled "power conditioners" and you'll see what i mean...

ill take a look at that.. thanks a lot guys..

i had another question. You guy said if i unplug the cable from the tv and the noise goes away then thats where my problem coming from. But what if when i unplug it and it gets a lot worse. What does this mean?
