I've heard that cable TV leads are often responsible for ground loops. You could try disconnecting that (or any other cable that comes from mysterious other places) and see if that helps. Otherwise, be systematic and disconnect one thing after another. Or use something that interrupts the ground pin of an AC plug (like a two-conductor extension cord), and try each component in turn.

If it's the receiver, begin visiting your local thrift (charity) stores regularly. A/V receivers (sometimes even with early versions of HDMI) are showing up, usually under $50. (LCD TVs too; saw a 32" Panasonic at the Salvation Army for $170.)
