Just received my 50pz85u.
First impressions.
This is an incredible TV. PQ is great, features are nice, and the design is very sleek (Not nearly as wide as last years 50 inch models). Overall extremely happy with this purchase. NO dead pixels that I can see.
In regard to some of the issues addressed in this forum, I have seen no phosphor trails (even when I hooked up a wii), the blacks are pretty goddamned black (I have not played with the settings yet/ and also have no comparison point in the home), and the anti reflect screen is very good. There is some reflection, but nothing that has forced me to change the lighting in my extremely bright living room.
I do not consider myself a videophile. Personally, when using this site to research my purchase, I read a lot of complaints about the little things with the TV. For example, people were complaining about a buzz coming from the back of the TV. Yes, when I stand behind the TV and place my ear near the TV I can hear a faint buzz. Given the size of the contraption I just added to my livingroom, I would think it was weird if it was whisper quiet. For those of you considering the set, rest assured that you cannot hear any noises when actually watching the TV. This is not a concern (at least not on the set I received). So, for those in the non videophile boat, I will offer this - You will be very, very happy with this television. I damn near jumped out of my skin when I ran the Matrix Reloaded highway fight scene (in HD). Absolutely incredible. And, I dont yet have a blue ray player. I can only imagine how good that will look. Still early, so I will repost if necessary, but I dont anticipate that.
