FWIW, this has been my process and I have no IR issues at all. I ran the screen using slides to age the pixels equally, for 200 hours. I used the screen in the meantime but was sure to have full screen content with no graphics during this period. The rest of the time I used the slides and left them running overnight etc. Since then, and because Panasonic say that the screen is not entirely 'safe' from IR for the first 1000 hours of use, I use the scrolling white pattern every evening after I have finished viewing. My screen is UK spec and there is no time limit on how long the scrolling pattern can be left running, so I set the Timer for 90 minutes and then leave the pattern running and go to bed. If yours is restricted to 15 minutes then you could use 'white noise' from a detuned TV source and set the timer for 90 minutes with that. I shall continue to do this until the screen has approx 1000 hours on it. So far, I have no IR at all, even when looking at a black screen in a pitch dark room.
Are the slides you have been using from the IR thread on page 2 of this forum (created in 2005)? I need to get a good DVD to run I guess to break it in. Instead of the scrolling white pattern after 200 hours can I just continue to use the slides? I would like for the process to be as automated as possible because of the NFL season coming up. I will be able to get almost 200-250 hours of slides from the time my screen arrives and the time the season starts! I know someone said 400 hours is the safe point. Anyone else found this to be the case?
I can't remember where I downloaded the slides from - but any slide set will do. The slides serve a different purpose to the scrolling pattern. The idea of the slides is that they work each pixel exactly the same for a defined period - it is important to age the pixels equally for the first 200 hours before calibration. The slides are not designed to combat IR, but they will to some extent simply by being 'clean' full-screen images. The scrolling pattern is specifically designed to remove IR.
