I have owned my KDL-40XBR2 for about 6 months now. I did notice a slight clouding issue when I first bought the set, but I thought it would be safe to ride it out and see how it goes. Over the past few months as I have added different titles to my collection, such as The Descent and atempt to watch these type of movies at night time, the white clouds become vary obvious and so do the flashlights. I have read about this "firmware upgrade", which Sony released to atempt to cover there ass, but that piece of software has failed and does not fully correct the problem, but only masks the clouds to a certain degree.
Now with the XBR4/5 I think its safe to assume that Sony will be on the ball and have this issue resolved. It should be a short period of time before the XBR2/3 line is discountinued and no more will be manufactured.
I have yet to coordinate a repair with the Sony warrenty department, but will once these new TVs are widely available on the market. Do you think Sony would agree to replace a faulty XBR2 set for a XBR4? Or will I be stuck playing the TV game and end up recieving 4 or 5 of the same models?
