No, they don't.

Can light leakage be a problem with LCD technology? Yes. However, I currently own two LCD TVs, one of them a 52Z5100. As I have mentioned before, my HT room is essentially a cave, from a darkness perspective. I don't have a single flashlight and/or clouding at all. Zilch...Nada...Nothing! I can even crank up the brightness and/or backlight up pretty high, if my mood dictates...No flashlights, no clouding, no haze.
Have you tried lowering the brightness, contrast, backlight or Advanced Contrast Enhancer? Have you tried shutting off ACE, light limiter, black corrector, properly setting gamma or properly setting Scene in the preference menu? Also, leave the white balance controls to their default positions, unless you have a colorimeter to set it accurately. Have you used Digital Video Essentials, HD Basics or Avia to properly set the adjustment parameters of your set?
If you haven't used a calibration disc to properly adjust the basic to intermediate settings on your television, you are doing yourself a great disservice. Might I also suggest bias lighting on the wall behind your set if you don't already have the Bravia wall mounted.
Many consumers will change the settings to the maximum levels, thinking that more is better. Heck, even the manufacurer's crank up the levels by default, in hopes of having their particular brand/model stand out against their competition on the showroom floor.
If you don't have a calibration DVD, even the THX Optimizer, which is a menu choice on most, if not all THX films is better than nothing. Even that is better than 'eyeballing' the settings on their TV. If you do all of this (and I'm certain some of our fellow members will come up with more) and you still have a high level of light leakage, then it appears that you may have a defective set.
I just don't like it when a product is categorically labeled as being crap by using blanket statements implying that "they all suck". So, please
do these two things (user calibration and if that doesn't fix it, get a tech out there) before you continue bad mouthing what myself and others believe to be a fantastic panel.
It also couldn't hurt if you let us know what your system configuration is , how the components are connected and what your video settings are on the Z. You need to look at settings on your components, as well. Just off the top of my head are black enhancer settings on DVD players or AVRs, having RGB selected instead of component, inadvertently setting RGB to 'full range', instead of limited when you are not using the Z with a computer.
There are also contrast and brightness settings, among many others in DVD players, AVRs and video post processors that could be magnifying or even causing the issue.
I hate to sound like I am slamming you, Nate...There are just so many simple on/off settings alone that could be contributing or even causing the very things that you have been upset and posting about, practically every day.
We can't read your mind. There are thousands of members here who have forgotten more than I know. I try to spend as much time as possible learning from them. We don't know what level of expertise you are at, hence, we don't know what you have, what you have set or not set and whether or not you have ever tried to do a user calibration. But here's the thing...Speaking for myself, if you just did some research about this and asked specific questions rather than implying that Sony makes an inferior product, I would go to great lengths to help you, as I'm pretty sure that many others will.
