Well it appears that Panasonic has agreed that they designed their plasma displays to increase idle black over time. They are changing the design a bit for the 2010 models saying it will "improve" this premature idle black issue.
Fortunately my display still looks good, but I am not appreciative of Panasonic stance on this issue since they appear to be saying the display was designed this way even though some displays may have a large jump in MLL in a relative short period of time.
I have to believe from what I have read that some displays are developing this problem because of this design and feel that Panasonic should take some action in those cases. It appears that they will not be.
Here is the latest CNET reponse.
Any input here would be greatly appreciated, thanks.
