I just received mine. I am having trouble w/a bizarre ground loop issue. When I plug my video out from my receiver to my tv to perform auto setup, I get the hum w/ the ground screw in. W/o the ground screw I get the hum all the time. If I unplug the video out from receiver to monitor, the hum goes away????? Also, YPAO on the Yamaha Rxv2400 is really having trouble w/ the 500. It is 8.5 feet from my listening position and it is trying to set it as 19 feet away??? At +5.5 db which is blowing the roof off!! Any suggestions?
