I just set up a referbished hk dpr 2005 and i am getting a buzz (more of a static white noise sound) from only one of my speakers/ channels. I have tried different speakers and cables for the channel, it's a suround sound channel, and I get the same loud buzz every time. Volume has no effect on the buzz, and it is noticeable from the time i turn it on, it start's off at a lower volume but quickly rises. I have unpluged all other equiptment on the surge protecter to see if there was a gorund loop but could not find one. All other channels work fine it is just the left surround sound has the problem. If i set the reciever for 2 channels, turn off the surround sound the buzz disapears. I am not sure what to do, i read the ground loop information but could not find the problem by unpluging, changing inputs etc. Could it be a problem with the speaker terminal? should i send it out to get fixed or replaced by hk? Any help would be greatly apreciated.
here is what is in my entertainment system, all of it.
