I'm getting my 55a2000 on tuesday, so now I can post here.
It seems this thread has been getting a lot of green blob panic lately.
Regardless of any percieved issues, I believe the A2000 series is an excellent value based on all the research I've done.
Those of you with green tint woes, do some research on the human eye's perceptions on the color spectrum. The Wikipedia article on Color_vision is a good place to start.
If you're picky about it, have your neighborhood ISF guy come calibrate your set and explain it to you. If it doesn't work out, return the TV. Some other guy will be glad to get an open-box price on it, and won't notice the green at all
The gist of it is, the color we are most sensitive to is green, and it's also the color that sometimes hardest to produce properly. After having an intro to monitor calibration training myself, I understand why any set would show blacks and whites as green. Even the color (or more specifically, chromaticity) settings being incorrect could make anything look overly green.
That being said, I have seen several of these in various electronics stores side by side with other sets, and I did see a KDS-60A2000 where everything black looked greener in comparison to the same image on other sets. I would venture to say that the average consumer with the set at home would not notice a slight color error because we have no reference to compare it to. Color accuracy is neither a myth nor a showstopper, it's simply dependent on the consumer's perception. And the ability of the set to be calibrated to produce accurate colors, of course.
I still purchased the A2000, because of all the different TV's on the market, this is the one model that stood out - even with the competing DLP's from Hitachi, Mitsubishi, and Samsung right next to it on the same image feeds. I also got to see it playback local SD cable. I was impressed with the SD, it upscaled well.
I also got to see the "Hawaii demo" and it was very eye-catching. Some retailers have this be the first TV you see when you walk in the door, and others have it hidden in the back. I still somehow see the A2000 as the shining star overall among the group and after seeing 4 demonstrations of it with giving other TVs an equal chance to wow me, I think I made the right choice. You have to look at the big picture. OK, pun intended.
Thanks for letting me share my observations.
Please, carry on amongst yourselves.
