That'd be a great April 1st joke...
Uh, that might not be a joke at all, I was just on Amazon researching reviews on some new Pannny Plasma models, and one person is claiming that his black levels are rising.
Black Levels WILL Increase (Get Brighter) Dramatically After a Short Time, March 24, 2010 By Christian Z. Newth - See all my reviews
This review is from: Panasonic VIERA TC-P50G25 50-Inch 1080p Plasma HDTV (Electronics)
I am the owner of a 2009 Panasonic G10 and I wanted to write a warning to all potential buyers of this product. 2008, 2009, and 2010 Panasonic plasma TVs have a 'feature' that increases voltage after predetermined amounts of viewing. This feature is causing 2009 plasma screens to have significantly increase black levels (~3 times brighter) after approximately 1000 hours of use. Panasonic has responded to this incredible revelation by saying that this is a standard 'feature' and that the TVs are operating 'normally'. From CNET, who tested sets at different hours of usage: "According to our measurements, the models with 1,500 hours both reproduced black at 0.023 footlamberts; the 500-hour models measured 0.008". If you do the math, this represents almost a threefold increase. People who purchased these sets are realizing that they purchased a 'lemon', as one of the main benefits (deep black levels) is a lie, or at least a 'temporary feature'. As far as the 2010 models go, Panasonic has indicated that the same 'technology' is being used (ie voltage increases) but that these increases will occur more gradually. It is too early to tell what exactly the company means by 'more gradually', but what is certain is that Panasonic had shown utter disregard for those that purchased 2009 sets. Please head over to the professional review site CNET for more information: [...] Or search for 'panasonic black level problem' on Google. Another option would be to search for the name of the CNET editor who is covering this issue, David Katzmaier. Buyer beware!
