I don't think anyone is worrying about a few minutes, but watching the History Channel for a couple of hours, as one poster mentioned, can cause IR issues. It certainly did for him. There have many other posters with similar stories, including several I've gotten in PMs (probably because they're afraid to post it publicly for fear of attacks.)
I was at a Magnolia yesterday and the sales guy there is an occasional poster on AVS and a really good guy. He understands video and has his sets displayed better than any Magnolia I've seen. He tells customers about the difference between torch mode and a calibrated mode and even tries to demonstrate that as best he can with some generalized settings.
Despite being careful with their new plasmas, and trying to avoid torch settings at the beginning, he showed me panel after panel with clear evidence of IR on some and more subtle, but visible IR on others. These are not panels that have been running for 1 year 12 hours a day on the same channel, but relatively new panels. They may be displaying ESPN or some similar channel for longer periods than I would, but nonetheless there is clear evidence of IR.
On Robert's brand new F8500, D-Nice picked up a slight trace of IR, but fortunately it went away after a short period. So this is one reason why I insist that posters that claim there is no issue with IR are doing people a disservice. Look, I still have a 4-year old 42" Kuro plasma and it shows zero signs of IR/burn-in. I don't believe my 60" Kuro did either. But I was very careful for the first 200 hours and avoided static images, blazing channel logos etc. Today my wife watches what she wants to watch for as long as she wants. Her viewing habits haven't impacted this display. Then again she doesn't watch some of the worse channels for this, like the History Channel.
So I want to make it clear that IR is not
inevitable with common sense precautions. But posters that say no common sense precautions are necessary are just wrong and are risking providing poor advice to other AVS members who may well get IR by treating a plasma as if it were an LED. If you say "I never got it and I did absolutely nothing to prevent it", well I say good for you. But we have many posters who have experienced IR and burn-in and are not crackpots, unknown posters, or people with an agenda.
Follow common sense precautions, particularly when the panel is new, and you should have no significant issues.
