I would tend to agree with a bell curve scenario also.. Though whether it's a panel or a driver board with the issue, I would still imagine that the firmware could be updated to include a "driving voltage fine-tuning" adjustment in the SM.. but as noted earlier, they would need a definite "reset" button press combination in case someone went too far and the TV wouldn't turn back on..

[quote=gregmp;18088253Not a perfect TV... good luck finding one. Panasonic may have goofed a bit on some of their compromises, but the TV is still pretty good.
Black Level will stabilize and IR goes away in time. +1000 hrs. looks better than 500-800 hrs. The picture is better than 80% of the tv's out there. Hope it stays that way.
Go buy another TV, waste your money, and end up with some other tv's set of poor compromises... NO THANKS.
I'm a little dissapointed that my tv is not as good as new in one area. Color and picture noise both get better in time and THX mode is fixed.
Get a bias light and blacks may look good to you. Your eyestrain will also be reduced.
I've also thought about putting up a backlight when I wall-mount in another couple weeks.. having some ambient back light would probably 'fool' your eyes pretty easily into thinking those blacks are even darker... and for the majority, a simple brain fooling is all that's necessary, regardless of what the meter says..

Infinite Black works only whenever my set is in its "good black" stage.
So, yeah...the next time I have friends over for a movie night, I'll be sure to let my set "warm up" for an hour beforehand.
I've decided just to wait until I rack up several hundred more hours and see how things look then - especially since I'm only at 600ish. If Panasonic doesn't provide a firmware and nothing stabilizes at an acceptable level, I'll most likely exercise my service plan with Best Buy just to see if I'm able to get anywhere.
Interesting.. so for those of us coming from an audio background who let our amps 'warm up and stabilize' for a few hours before critically listening, panasonic plasma owners should do the same before critically watching
Actually, I'd be interested in hearing what other people say about plasma's getting darker after being on for a few hours..
