I received my 65GT50 yesterday morning. I have to say that just about all my worries with this TV were for not. I have a bright room with windows behind the TV, and my family plays games a lot.
I decided that I was just going to set the TV up and use it. No break in, no babying. If the TV can't stand up to how it will be used, then I'm returing it, as the technology isn't for me. My kids played Mario U for about 4 hours yesterday. They paused the game and left multiple times (although the Wii does dim the screen after a while). I thought for sure that the bright time and score in the upper right corner would be a problem. I had zero noticable IR yesterday, and I looked for it.
The TV was more than capable of displaying an excellent picture in the brightness of my room. The colors and motion handling are excellent on this screen. I've never seen what I displayed look so good before, from all sources. I am able to see faint flicker sometimes when I'm looking away from the TV, but it isn't a concern or problem for me.
My only problem with the set, which will be an unfortunate deal breaker for me if it can't be fixed, is the buzzing. I sit about 12-13 feet away from the screen. I can hear it change as the screen brightness changes. I think it is the panel, because it is uniform from top to bottom on both sides of the back of the TV. It's hard for me to watch anything because it is distracting. My wife can't hear it unless she puts her ears close to the back of the TV. I have much better hearing than she does, though.
So, I'm going to play the exchange game, hoping for a set with no IR, just as excellent of a picture (this isn't really a concern), and one that is more quiet. I don't care if I can hear some faint buzzing from a couple feet away, but 13 feet away is a bit much. I really hope this works out, because this TV is superb otherwise.
