Guess thats just plasma then.
Well, to get a broader perspective on the buzzing, I spent some time looking at the Amazon reviews of the ST50. At the time, there were just over 300 reviews and of these 48 mentioned buzzing. 25 of them reported buzzing that is similar to my (and that of others in this thread) experience. Here's a typical description
" Buzzing. I have had issues with buzzing...unfortunately. It's most noticeable for example if I'm watching a 480i video, not high-def, and something bright is being shown. A candle, the sun, etc. A very standard TV buzz sound emits from the screen. It's annoying. If I crank the volume above a quiet, night-time volume I normally use it's not noticeable, which may give you an idea of how loud the buzz is. It's not too loud, but noticeable nonetheless at quiet TV volumes or at any volume if there's no audio coming from the video to hide the buzz noise.
I sit approximately 9 feet from the TV set."
On the other hand, the other reviews either say they don't hear buzz/buzz is only heard when very close to TV or they don't mention buzz at all. Here's a couple of typical examples of a review that says buzz in negligible:
" I sit anywhere from 3 feet (when playing FIFA on the Xbox) to 12 feet (when watching movies) away.
Under any normal circumstances, I hear no buzz at all. In order to pick up any hint of a buzz, I have to mute the television and either (1) place my head within one foot of the screen, or (2) stand behind the set. Just about every plasma in the universe will do the same. I've not had to "tune anything out" or "learn to ignore" any noise. I just don't hear it (and my hearing is fine)."
"No buzz on my ST50. Its dead quiet unless you put your ear BEHIND the tv and listen during an all white picture. I don't suggest watching TV behind the unit. It seems plasma buzz varies unit to unit."
Based on my research, and having listened to a couple of TVs at a store, i am not willing to accept a TV whose buzz can be heard from 12 feet away.
