Hmm well maybe you got a bad tv? Also are you noticing the IR while you are doing other things or when you really look for it and or use test slides to look for it. My old plasma had some minor IR but it would go away and I never really seemed to notice it during use. I can't see how a plasma that is 6-7 years newer and known for being one of the best bang for your buck tvs out there could be worse than my old plasma. Maybe a certain batch of plasmas were poorly built?
I pulled the trigger an ordered one. I can't really wait till next year to buy a tv and I dont really know what better option there is for a 60 inch for about 1650. I guess what I will try and do is break it in before ever using it and then proceed to see if I have IR issues. I suppose if I come across any issues that make the experience unenjoyable, aka IR, Input lag, rainbow whatever then I can return it. i would probably suffer losses but I could probably play it off as defective if I was getting noticeable IR.
