    I have a Pioneer projection HDTV. It has developed a very audible hummmm.

    It wasn't as bad until I recently moved and re-setup my system. I now hear a large humm from particularly my center channel speaker.

    A little about the setup now.

    Using a Yammy RX Z1 as a pre-pro and a seperate 5 chanel amp. The center connect runs behind the TV from the pre pro to the amp (They are on seperate sides of the entertainment cabinet). I had the TV and everything plugged into a surge protector. I tried to unplug the TV from the surge protector and plug directly into the wall but that did not help (same circuit I supose).

    Any thoughts or anything perhaps I forgot to mention.

    Thanks in advance for your comments.

    Phil

    * Filter capacitor in audio power supply section has gone bad.

    * An input jack ground has become separated.

    Skills of a TV serviceman are required.

    Sounds like a ground loop.

    Remove the cable/satellite feed and check if the hum stops.
