Back home with my 60ST30. Everything went well from start of pickup to finish.
Congrats! Hope you enjoy the set: at its best - Blu-ray or HDDVDs - the 60" ST30 shows a Wonderful picture.
If you are stepping up from a smaller sized panel, and/or sit close enough to the screen (say around 9ft or less...), don't be SHOCKED if you find that a panel this large tends to Show Off ALL of the Inherent Flaws in whatever less-than-ideal program material you view!
Seriously thinking about moving all of our SD
DVDs from the (basement) "home theater" to the LR, as our older 50" Pan plasma does a nicer job of Masking their PQ issues. (Our experience is that it takes about a 12 foot viewing distance with the 60" to roughly equal the Apparent PQ at 9 feet with the 50" - GIVEN SD Material....)
We've had 3 60" ST30s in house (plus 1 60" S30 - technically 2, but one had a cracked screen...), and ALL have been bothered by the Green / Pink (Magenta) tinting that characterizes 2011 Pan Plasma sets.
Our current set is a Nov Build 60" ST30, also from CostCo, and while it DOES have both Unwanted Green & Pink, it is still easily the Best of the panels thus far: with MOST programming, MOST viewers probably would not notice the issue, or would assume it is simply part of the material as opposed to a panel flaw. (Unlike the earlier panels, the Green on this one SELDOM tints Faces, instead showing up in background objects, where it is easier to ignore.)
Still, would recommend trying to rack up as many hours on the panel as you reasonably can before your 90-day return policy ends: although Green TENDS to get Better as the panel ages (at least up to 600 - 700 hours - the limit of our experience), you may
find that the Pink/Magenta will grow worse over that same time period.
Also, other than Green / Pink issues, all of our panels have seemed to IMPROVE in overall PQ over the course of the first couple of hundred hours of usage or so. We kept the first panel the longest - around 700 hours - and it had noticeably Deeper Blacks and APPARENTLY more "pop" when we sent it back than any of the other panels have had. (IF you look at "letterbox bars" and find them disappointingly "gray" - instead of black - give the panel a while before getting too upset!)
And, while it is probably just common sense, we have also noticed that certain letterboxed material produces "Blacker" bars than other sources: TV - even "HD TV" - tends to be the worse, while MOST (but Not All) Blu-rays tend to be the best...
After 150 -200 hours or so, watch the blu-ray versions of "Dark Knight," the "Star Trek" reboot, "Iron Man 2," or the "LOTR Extended Version" - these should look Pretty Good NOW, but once the panel settles in they ought to look Great!
Best of Luck with your new panel!
