There are so many people out there that don't have any idea of places like this forum, and I am sure like you, they have NO idea there is a problem with their set, thinking the clouds are a supposed to be there since for many this could be there first experience with a LCD flat screen tv. Good luck with the tech!
I can't help but wonder if they plan on ever rectifying the issue if they are saying it is "normal". Very soon they will be moving on to the next generation of LCD sets....they are constantly putting new product out there. The XBR2/3 is just one rung on the ladder. Lets just hope they get their act together someday. Right now I have little confidence that they will. They don't seem to give a damn...and that is the hardest thing for me to swallow.
I don't know the answer to your question....but if you contact Panasonic about the problem I would be very interested in knowing how they handle the issue as compared to Sony. Right now, Sony disgusts me.
Kronius, I think it would be wonderful if you let Sony know you have cancelled your order (assuming you have)...and let them know why. I think Sony is on a downward trend....and it pains me to say that. I will have to change my buying habits, but I will. I just can't believe this whole situation!
