I had a quiet talking scene with two characters walking down a hall with lights above them every few steps. So it would go dark, then they'd be lit by the overhead light, dark, then light, etc. The buzzing would pulse with that and could be heard over the dialogue.
I would say if you can hear buzzing while watching what you normally watch with the sound at a level you typically listen, it's a problem. Anything else and I wouldn't worry about it. Had mine not been so blatant, I would have been okay with it. I mean my cable box and PS3 both make a significant amount of noise so it's not like my room is dead quiet to begin with but the buzzing can be heard over that. I wouldn't even have a problem if the set just buzzed independent of brightness, it eventually becomes white noise when watching something that is constantly bright, like the court of the Duke-Miami game on right now. But it is the alternating between light and dark that's really a killer.
Only you can be the judge though, if it doesn't bother you during regular content and you're happy with everything else, I wouldn't worry about it because who knows the problems a replacement could have.

As far as pop goes, try HDmaster's wide color settings (just go back a few pages) I'm not sure who's settings you have listed; most of the numbers are usually similar. The low red and low green seem pretty negative ?
