Well, there is no such thing as a perfect set on the market today. With that having been said, outside of some very small (I mean hard to see) anomolies in the cross-hatch pattern, my set is very close to optimal. I did not have the problem that you are discussing here. At least I do not think that I do. My eyes are critical, but they are not "trained".
If you look into some of the posts on the present front page of this forum, you will find discussions about blooming and ghosting/ringing etc. A common thread throughout these posts, is that the Sony "authorized not factory" service techs try to describe 90% of all of the problems listed as "normal". This is just a prime example of poor service tech training or experience. Sure, some problems are within specs, but this seems to be a major cop out being used by non-factory service personel. I have had problems with some independent repair/warranty centers in the past.
How old is the set? If it is new, I would demand a new replacement. If you have had it for awhile, I would demand Sony send out a FACTORY service technician, even if I had to wait several months (with a problem that I could live with). I had a small problem with my set, but after a similar experience with an "Authorized" service center, I purchased the service manual and figured out the problem and repaired it myself.
Sal, it is not a unique Sony problem. Dell, Gateway, and all other CE manufacturing companies have had cutbacks to improve the bottom line or reduce their losses. Customer service is one place that they can gain imeadiate monetary improvement. It is a short term gain, with long term consequences for their sales. I believe persistance and continuous phone calls will eventually force them to lube the "sqeaky wheel". Please keep us aprised of your progress.
I love my HDTV!
