But at least the high profile reviewers will be on the lookout for the issue in the new models.
Assuming they got a normal set, my theory is that the CNET reviewer didn't hear the buzz because they were using the PN50C8000 as the review sample. (see below) And that because of something about the 50" size it won't buzz nearly as much as the larger sets that most people here have issues with.
I have no idea where the inductor coils are on the 50", but there is something about the small set that makes the buzzing much less than my 58" was. (Maybe the coil location or panel size or less stress on components?) I've compared 2 different 50" C8000's to 2 different 58" C8000's also with similar buzzing results. The 50" gives the normal plasma "buzz" on bright white screens, but step 10-15 ft away and you hear almost no directional buzz on black... The 58" buzz on the other hand was clearly audible from 15 ft away on black.From CNET (page 2):
Update October 19, 2010:
In addition, we made an unrelated update to the bright lighting section to include a comparison to the Samsung PNC7000. It's also worth noting that, unlike some readers, we didn't experience any unusual buzzing sound on our PN50C8000 review sample. It was quieter, all things being equal, than the Panasonic TC-P50G20, for example.
The good news is that CNET and others are going to check for this in 2011 too I bet since they got so many comments in 2010... So hopefully Samsung isn't able to get away with the "your buzz is normal" again...
