Hi I recently purchased an HP-S4273 TV. I am running my sound through a Yamaha HTR-5860. My center channel speaker is buzzing and it's driving me crazy. Does anyone have any suggestions on how to figure out why the buzz is happening?

I think you need to give us a little more detail regarding the problem. Tell us how you have things connected. Are you using coax or Optical output from the HP to the receiver? If coax have you tried the optical connection? Do you have the same problem when running DVDs or another audio input? Do you have Cable TV? Lots of possibilities for hum or buzz, but need a few more details to help you out.
