Plasma rainbows or "plainbows" is what I've heard it called, and the former is the term I used.
Occasionally (It seems to be when something colorful moves across a very dark background), I see what in PC monitors is known as overaggressive RTC, except that it's rainbow-colored. So it's like a thin outline displayed slightly ahead or behind of the motion with a shimmering rainbow effect. It's somewhat rare, and only lasts maybe a frame or two, but noticeable when it does happen. I don't "think" that this is a problem with the source, I've seen it in a blue-ray, a PC game, and on netflix via PS3, so it's either a factor of plasma tech or just an artifact caused by one of the postprocessing options I haven't bothered to turn off yet.
Someone else thinks this is describing phosphor trailing. I would think the two can occur together, but maybe I just can't tell them apart in certain scenarios. I would say "pure" phosphor trailing is what I observe in screen wipe, where the leading edge of the white rectangle is smeared blue, while the trailing edge is smeared yellow. If the RBE were also occurring, I'd see occasional random flashes of yellow/green/rainbow when I move my focus or blink. But I don't see that in screen wipe. However, it's all over the place in Sin City, the Alien opening credits, and various other content with similar characteristics. In any event, the S60 doesn't improve much on the ST60 in this area, which is a disappointment, but some say it subsides after a few hundred hours. The S60 does improve some on the flicker, which was quite bad on the ST60 at its Home Screen, the USB media player screen, computer desktop, etc.
Within about five feet of the screen, some colors, particularly shades of grey, look a bit grainy, basically like static. My guess is that it's also caused by overaggressive postprocessing. It's not visible past about five feet though, so it's not a significant issue.
I believe that's just normal dithering. I saw it on the ST60 as well, and it had the same characteristics. Look at the bars in the AVS709HD Black Clipping pattern to see it really emphasized.
There is a very mild buzzing. I can only hear it when I'm less than a foot from the set, so it's insignificant. Hopefully it never gets worse.
My goodness, another positive report on buzzing. My S60 is louder than the ST60, whose buzzing was clearly audible from 10' over dialogue and even soft background music in high APL scenes like the typical Family Guy living room scene, which was a major reason I exchanged it. Unlike the ST60, it doesn't respond as well to decreasing contrast, and even with the ST60, I couldn't decrease contrast enough within acceptable limits to get the buzzing acceptable. The S60 also often has a rhythmic component to the buzz when showing a static image.
On the noise front, the S60 adds a highly directional pure tone audible when then there is a lot of black on the screen, like in the XBMC UI, which is similar to what I've heard from CCFL Sony LCDs. The S60 also suffers from loud popping noises, which sound a lot like I remember arcing in CRTs. They occur while the set is on and go on for an hour or more after it's turned off. Thermal expansion/contraction I guess (though I'm surprised how long it goes on after powering down), but the ST60 did not do this ever. Given my usage patterns and environment, This Will Not Stand.
The initial channel-scan (which took about an hour) the TV did when I hooked it up left a dim blue box in the center of the screen for about ten minutes. That's the extent of IR I've run into, but I don't watch sports or news channels, and haven't done much gaming yet.
I find the S60 acquires IR just as rapidly as the ST60, within 5 minutes, but it clears it much more quickly with Screen Wipe or just watching regular content. The ST60 would still have IR visible on (say) a 30% gray pattern acquired after no more than 10 minutes of (say) the Viera Menu text followed by hours and hours of slides, regular content, and screen wipe. The S60 loses it after a few minutes of screen wipe.
One thing about the S60/ST60 TV tuners: They seem to be much better than Sony tuners.
Concerning the remotes, the ST60 had a problem with its own remote and my universal remote, where single button presses would often be interpreted as repeats, making it very inaccurate to navigate the menus. The S60 does not have this problem.
Anyway, I have to say that my first two plasmas ever suffer from unfortunate noise levels and weird artifacts like the rainbows. However, the picture quality is far superior to LCDs, and while discouraged, I'm not quite ready to give up.
