I have a front ceiling mount Sony HT, with its own outlet. I sometimes pick up a faint hum. I found that when I have the theater room lighting very dim, this is when I can hear the slight hum. When the lights are turned all the way up, nothing. With the lights off, nothing. You might want to check this out in your own theater room. See if what you are hearing might be coming from your room lighting or might be caused by the dimer controls in the wall that are remote controlled.
Thanks for the suggestion Dobeman, but tested without any lights on, and once the projector is plugged in get the hum....btw the hum is not loud, but can be heard while seated if an unused input is selected, or if using very low volumes on an active input. Tonight I watched the Heat/Pistons game with the projector plugged into the a/v outlet, and no hum/buzz. Tomorrow will test the dvd player, and if no hum, then off to home depot to get something to mount the power cord and extension on the ceiling and wall. I have a Panasonic ae700, and have to unplug the power cord after each use (prevents vb lcd panel distortion)....was thinking of either running an extension to an easier accessed outlet (need to use a ladder now) or some type of remote cutoff for the a/c of the projector..the 990 hum/buzz issue just gives me another reason to run the power line.
