This makes me think that mine could be normal after all.
Here is how I tested it at different volume levels and judged it's a buzzer.
1) When the TV is muted or volume below 15, I can clearly hear the buzz (like the sound of a neon light, as others pointed out) anywhere in the same room.
2) At volume between 15 and 25, the buzz is covered up and I can only hear it when I try hard to or there is a quiet scene. At this volume level, I can clear hear the buzz only about 2 - 4 feet away from the set.
3) Above 25, I can't hear the buzz unless I put my ear upclose to the back of the set.
I have compared it with my old CRT and this is still much louder.
It's very hard to compare the buzz sound in store because all the background noise. Honestly, the buzz is not really annony when you're not trying to hear it. I guess the fact of knowing there are quieter ones out there frustrates me more.
I'm getting my third replacement delivered tomorrow. The first two are both Nov. Mexico made. If I get 3 buzzers in a roll, I'd choose to wait a while before doing an exchange again or having a samsung technician to check it out.

That said, it's nothing close to as loud as the old tv, and I can hear the same thing with my old CRT.
It's interesting that lewddog21 brought up age. I'm 26 and neither the Samsung tech (in his fifties) nor the Circuit City repairman (probably in his mid-forties) could hear the really loud buzz of the old tv. I could hear it even if I turned the volume up to 30, left the room, and turned on a tv in the other room. My 56 year old father could hear it though, so maybe age isn't everything. Neither he nor I can stand the volume levels at concerts though, so maybe we've just had less hearing loss as a result of trauma from loud events. My mom could barely hear it, and she loves concerts, parades, fireworks, etc.
