There is a thread about burn in at the top of the plasma forum at avsforum.com. A few things;
1. I have had my plasma for over 2 years and I dont see any burn in on my plasma.
2. A set is most vulnerable to burn in during the first hundred hours of use or so ( NOT an exact figure)
3. Leaving up black bars for extended periods of time CAN cause asymetric phosphor wear. I am using that term not because I am taking the SAT soon ( that was 20 years ago), but to stress that uneven phospor wear is the true danger. With black bars, that uneveness is defined as the stuff inside the black bars wears differently than the non-firing pixel black bar areas of the screen. The pixel phosphors have a time to half brightness, or a half life for all of you chemistry guys. With normal viewing, this occurs evenly over time. Constant black bars disrupts this so uneven phosphorescence occurs. Watching movies with bars, which I do frequently, will not cause this. Leaving this up for days on end might. Also, adjustments on the DVD player may change the area of these bars. Or by using the just or zoom mode they can be eliminated entirely. I leave them for movies because thats the way the movie was cut.
If you get this type of problem, use the reverso screen which turns black to white and white to black--kinda like turning jeans inside out before washing them. That can even things up.
After image burn in- a different thing entirely is what you see at the airports where old schedules can be seen on the screen even though the video data is not being actively transmitted as such. If you see this-- DONT FREAK! It is often temporary in the home setting and goes away.
The above poster is talking about the Panasonic wobbler, an anti-burn in feature like he says.
