My KF60XBR800 has developed blue blobs and being that it's 8 years old I decided to retire it in favor of a new 60" Panasonic plasma. I am satified with getting 8 years out of it but I am somewhat disappointed with the history of problems with the optical blocks in the Sony products. That's why I didn't bother looking at Sony LCD or plasma TV's . . it's just my way of protesting, I guess.
