Receiver buzzing - DirecTV

I recently had a receiver go bad and the 1st one they sent as a replacement was loud and only way to stop buzzing was to unplug. Today I received 2nd replacement and this one buzzs too. I have been with DIRECTV since 2007 - and all my receivers have never been this loud. The receiver is located in bedroom and unable to sleep unless I unplug it. I'm now looking at other providers as this is getting ridiculous and taking too much of my free time.

This question, "Receiver buzzing," is about DirecTV channels, programming, equipment, and sports.
