They say that the new models will "apply the voltage adjustments, in smaller increments". There is your smoking gun.
Read it for yourselves. No need to start lying to yourselves, and just try to whistle while passing the graveyard.
At the very least, Panasonic should issue a firmware download that will adust the voltage increments to the level they claim they have put in the 2010 models.
I think you're probably not understanding. I think we all understand that there is technology in the 2009 models that adjusts the voltage. There's no question about that. I think we all understand that the adjustment CAN BE too aggressive. But you probably don't understand that not every adjustment is always aggressive or that every adjustment doesn't seem to be happening at the same time.
Some peoples' sets seem to adjust after 100 hours, some 200, some 600, some 1000... It doesn't seem to be exactly following the spec posted earlier.
The problem seems to be when the adjustment either happens at the wrong time or the adjustment is too aggressive itself.
As with the nature of televisions and electronics in general, even if you buy 60 of the same exact model of something, you can probably guarantee that the insides of all 60 are not exactly 100% the same. There's probably variation of chips somewhere or programming slightly, one of these variations or programming in the Panasonic TV models is causing some people grief. As it's making their picture look really bad. But because not all the models are EXACTLY the same, not everybody has this problem.
Nobody is deluding themselves. Some people get the problem, some don't. Everybody gets the voltage adjustment. (I don't know why this was needed in the first place, but obviously Panasonic thought it needed to be in there) As to when it happens and how bad is a toss up in regards to your set.
