I've been lurking around here for awhile, but rarely have anything worth posting. Now, I need your expertise. I recently purchased a 60EX720 as an exchange from Sony for my old KDS60A2000, which died the green tinted death. I received the new set on Friday and have fiddled around with it pretty extensively (though I'm a complete neophyte when it comes to most of this stuff).
Initial impressions are good, as the picture looks great and it is a huge improvement over our old set. Also, the 3D seems okay, as far as I can tell--but I'm not a huge fan of the 3D craze. Anyway, I do have one big, glaring problem with the set. Whenever the screen is black or in a dark scene, the upper left hand corner (and, really, almost entire left half of the screen) is really, really blotchy and "cloudy." It's not much of an issue during the day, and doesn't have a real effect on bright scenes... but watching movies at night (especially dark films or letterboxed) is incredibly distracting.
Here are two pictures I took to try to illustrate the problem (one is a videogame load screen and the other is a scene from Inception):
So, the big question: Is this normal? This is my first LCD set and I've never heard of such a problem before with LCDs in general. I did a little research online and read that 'screen uniformity' is what this issue is called, and many of the EX720 reviews state that the set has really poor uniformity. But, I just can't believe this is acceptable to anyone, under any circumstances. Sony is sending a repairman out to look at the set, and the repairman indicated he would likely just replace the screen with a new one, but I'd like to find out from others on here whether this is just typical of the EX720 or other LCDs.
If it is normal, are there any settings that can be adjusted to minimize the defect? Turning on the light sensor under eco settings seems to help a bit, but decreasing the backlight setting doesn't seem to have much impact on the problem.
Any help you guys could provide would be very, very appreciated!
