    I had posted before about my speakers humming when using my system. Someone replied and told me it might be a ground loop. I figured out that it was my tv (Elite Pro 610), that was causing the problem. Everytime I turn it on they start humming. I have BP2000's. Would pulling the speakers out so the back of them are even with the front of the TV work? I thought the speakers were shielded. It does not do anything to the picture. My center channel is on top of the tv. I have a monster HTS-3500, but I can't plug the tv into it.
    Any other ideas?
    Thanks,
    Chris

    I have bp2000TL's sitting next to an Elite rptv and there are no humming problems. You should try to clean up your cables a bit and keep the main speaker wires a bit away from the other wires, as there may be interference. When my wires got cluttered a bit I noticed a very slight hum in my center channel...but this went away when I cleaned up the wiring.

    I had the same problem with my Onkyo. The solution? Shielded interconnects.

    Chris: setup your system so the HUMM is noticible. Then disconnect your CATV coax. This is a common source of this problem.
    If the CATV coax IS the problem, try this link for a solution:

    Ted: No, not all interconnects are shielded. Some are made with twisted-pair wire.

    Try putting a 100 watt incandescent light in the same circuit. It worked for me.

    If your tv is not plugged into the HTS3500 what is it plugged into?

    It's just plugged into a wall outlet.

    PS A 100 watt light bulb really doesn't help. My difficulty has been in the CATV cable. By using a CATV RF Isolator (price $50) or similiar product you can reduce the hum to almost zero if it is in the CATV cable. of course there are eight million other possible reasons for the hum-interconnects, adjacent cables, cables on cables, other appliances, poor grounding etc.
    Best regards-Henry
