I was wondering if anyone had noted changes in their screen during the "break in" period? I had similar issues to JS88, but my main issue was with the posted contrast settings. I am over 110 hrs now, I have downloaded the recommended Calibration File and copied it to disk, but I have not had time to use it yet. However, during this period, especially the last 30 hrs. I have noticed the screen appearance changing and have gradually made adjustments in my Custom setting to compensate. When I posted my settings the other day, I had already backed Contrast off from 90 to 85 and Brightness from 80 to 70. Late last night I felt again the screen was too bright and way too sharp, so again I adjusted the Custom settings accordingly. Contrast is now at 80, Brightness at 60 and Sharpness at 80, and this time I had to jack the colour up from 35 to 40, when I switched the TV on just now I again notice it can be retuned some more. So is it me, or is the TV display changing as I write? Additionally I should mention my viewing room is always pretty dark and I had a DLP in this room before and initially tried for the same "look" as my previous unit, when I started viewing the "Panny" 18 days ago. The big negative so far for this TV and the Sony BluRay player I bought is the controllers are not backlit; so to use those controllers I have to turn a light on. Solution is to keep a little book lite next to the controllers and use it, if I need to manipulate a controller.
