And aside from those few posters who claim to have IR that lasts for days, there are probably hundreds on this forum alone who have confirmed that any IR they're getting goes away within seconds or minutes.
I would like to know how many can watch sports or a channel with heavy logos for 1 - 2 hours and not suffer Image retention after a few hours of playing different content to clear it?
The very first Saturday morning with my then-two-day-old PZ700U, with absolutely no break-in, i watched over 4-straight hours of recorded Speedchannel racing in 4:3 mode with black bars on the sides, SPEED logo in the upper right corner, and scoring banner across the top of the screen, and my Picture settings set at like +29 in Standard mode. At the end of this 4-hour marathon, i switched to an HD program and paused the image on a light blue sky scene and immediately saw the IR from the black bars and faint SPEED logo on the screen, then was amazed to see it quickly fade away in about 10 seconds and completely disappear. I got up close to the screen and could not see where the black bars were a moment before. Two years earlier on my old PX50U, that same test left IR on my screen for hours so it's obvious to me that Panasonic has pretty much eliminated burn in. You cannot get burn in if you're not getting IR.
Can i leave it on one channel for a few hours and come back and expect the IR to be gone in say 30 mins of different content?
I do it every weekend for hours at a time (Speedchannel again). I don't like stretched racecars. Or stretched women for that matter. Some things must remain OAR. And i watch probably 2-3 hours of local HD news daily with the station logos and tickers and still 6 months and 1,200 hours later, any IR i get disappears within seconds, and i still have absolutely no visual evidence of burn-in when i check for it. None. I'm not worried in the least. Even my old PX50U (about 7,000 hours) has no evidence of burn-in with the same weekend and daily abuse.
What furthers the confusion is that Panasonic do not mention the break in with their manuals. They seem to be oblivious as if they are the ones that never made the TV. Can't even tell us how long a static image has to be left on the TV to cause retention that would last hours or how long it takes to burn in.
So far i can not remember seeing any 2007 Panasonic owners that reported any permanent burn-in, and i honestly think it's just no longer an issue on the current models. I don't even worry about it anymore, i just watch 4:3 about 30% of the time and enjoy my PZ.
Is there a way to check for subtle burn in or IR, i.e. playing different colour backgrounds?
Posters have told me they contacted Panasonic for the what HDMI version the PZ700 has, and have been given 2 different responses, once again it seems Panasonic does not even know.
It's been verified many many times long long ago that all the current 2007 models are 1.3 despite the constant reocurring old rumors that it's only 1.2 (which was started by a misprint on Crutchfield's site). If you refuse to believe that it's 1.3 by now then just give up and consider it to be 1.2 and live with it. Exactly how would it affect you if it were not 1.3?
