I have 32V2500 manufactured on 10/2006. My friend has 42S2000 manufactured months before my TV. His TV does not have any clouds. I don't believe that Sony has very much brighter backlight than any other manufacturer. And why do they put this bright backlight if it cannot be used? I think you could even reason that you have bought an apple if the seller says it's apple when in reality you have bought an orange.
I do not believe my display is defective. I believe it is possible to induce a clouding effect / uneven backlight that resembles a mura defect by cranking up the backlight to uber-torch mode, but this fact does not mean the display is defective.
There is nothing to believe. Just use your eyes. Either there are clouds or there are not.
I believe that people should consider that their choice of uber-torch settings could cause them to see what they believe is a defect. Just because something doesn't look perfect under all conditions doesn't mean it is defective.
Award winning TV with the price tag of Sonys must look perfect under all conditions. What else could you expect.
And yes, manufacturers can make what they want and sell them for what they want.
Yes, as long as the buyers are like you. They pay a high price and are satisfied even if they get total crap. Andrew, for you information, this is called cheating. Don't be so naive.
