I've been following this issue with interest and can empathize with those who are experiencing excessive cloudiness/uneven backlight leakage with their expensive LCDs. Likewise, I am also frustrated that some people who posted in another thread just didn't understand the problem and were dismissing it by saying that it is normal because "all LCDs are like that." They certainly have no clue.
As I mentioned in a past thread, my 32" Sony LCD (model KLV32M1, made in Japan, July 2005 build date) which I bought in Sept '05 had very noticable uneven backlight leakage. It had 4 palm-sized clouds around 6" from each corner. These clouds were CLEARLY visible with regular TV/DVD programing whenever there were dark scenes or black backgrounds. For instance, it was extremely distracting to see these clouds surrounding the words "A long time ago in a galaxy far, far away..." at the very beginning of Star Wars.
Lucky for me, the problem remedied itself when I laid the set face down on a table, removed/reinstalled the back cover, and then stood it back upright. I did this out of curiosity because I wanted to see how the inside looks like. As I mentioned in the past thread, I hypothesize that this laying down may have "destressed" localized pressure points along the screen which may be causing the light patches or clouds. Just a guess.
To this day, my set still looks really good. Below is a link to a pic that I took of my screen under "extreme" conditions: the picture was taken in a completely dark room and the BACKLIGHT was at "10," which is the max setting. Other than the small patches at the upper corners, the backlight leakage/bleeding looks pretty darn uniform.http://i35.photobucket.com/albums/d1...9/IMG_2815.jpg
I hope you guys can get this issue resolved with Sony.
