Update May 3, 2009:
My original review of the TV was negative due to a problem of dimming during dark scenes. But few days ago Sony released a software patch to correct the problem and it worked for me. Now, the auto dimming can be turned off by setting the "Adv. Contrast Enhancer" to Off. Also, even when it's turned On, it doesn't behave like it did pre- patch, it now dims gradually rather than abruptly and it doesn't dim as much as it did before. Thank you very much Sony, I'm updating my rating to 5-star.
I'm very happy with the TV now that the auto dim is fixed. If you own the TV and having problems with the dimming, go to the support section of Sony's site to download the patch and the instructions on how to apply it. You will need a USB thumb drive formatted in FAT32, but if you don't have it, Sony will mail you one if you call their customer support.

Rating: 2 stars
When I purchased this TV few days ago, there were no reviews here since it's just been recently released into the market. I, however, looked at the reviews of the previous model (KDL-40V4100) and didn't find any serious complaints so I went ahead and purchased this TV. I regret my purchase and will explain why.
This is my third LCD TV -- the others are early generations LCDs from Sharp and Sony and they are still working great, but they are no match for the picture quality of this new Sony. There are a lot of good things about this TV and I would have given it 5 stars if not for one serious flaw.
The TV dims during dark scenes. And sadly it doesn't do it gradually, it happens abruptly 6 seconds after the start of a dark scene and it returns to normal lighting abruptly about 0.35 seconds after end of a dark scene. It seems to happen regardless of the source of input (I tested it with composite, and HDMI) and it happens on broadcast channels and cable and regardless of the "picture mode" and other video settings. There is no way to disable it. If you're watching a movie with lots of dark scenes, it's going to be a very annoying experience.
Take this example, while watching a documentary on first gulf war, there was a lot of night vision camera scenes and the TV keeps dimming during the lengthy dark scenes and when it does that, you can barely make out any details even with Gamma set at max. The dimmer kicking in and out is annoying by itself, much less the picture quality when it dims.
I contacted Sony support and they seemed clueless and recommended I initiate a repair request. I did an internet search only to discover many Bravia models suffer this problem. I initially thought I had a defective unit, but now I think it was intentionally designed like this.
The Sony came in a close second in the judging. Two members of the five-judge panel voted it first overall, and two rated it second. No one really disliked it. I can't say how I might have voted had I been participating blind, but I like to think I would have placed it on top, given my partiality to serious viewing in a darkened room and the resulting need for great black levels. As I noted earlier, the Sony also won raves for its performance with the lights on--although that was a very short part of the test and not included in the scoring.
