Anyone else notice a weird buzzing sound while watching CBS? It almost sounds like a vuvuzela. This is the second week in a row i've heard it, and it goes away at commercials and for other shows. Its just football.
I had a tv years ago that did that, turns out it was actually the equivalent of a bad ground at certain spots on the screen, where if it was White or other light color, it would buzz. If you notice it constantly during football, it may be due to where one of the static graphics is sitting (station logo, stat crawl bar, etc) at that spot.
