I don't believe that they should be. The design of the LED Televisions is supposed to reduce the possibility to have clouding ("screen uniformity", officially) effects as well as be more energy efficient.
I can appreciate the hesitation after reading many forums on these issues. Remember that a lot of these issues are readily available because people who don't have these issues don't necessarily log on and say that they're <u>not</u> having these issues, which is quite a vast majority of television owners.
That said, I would go into the store and play with the settings on the store's unit, as that should give you a really good idea of what your settings will look like at home. Go ahead and bump up the backlight, adjust the brightness and see if you can get those issues to appear. If not, it may be worth taking the plunge.
I hope that helps, and let me know if you have any other questions.
After exchanging out my Samsung LN46A850 four times at Best Buy because of the clouding/flash lighting/blooming issues (a popular discussion topic on this forum and elsewhere), I finally decided to return it and get my money back.
I was greatly dissapointed because I really liked the look, features, and picture quality of the 850 TVs, and even went through the trouble of numerous exchanges in the hopes that I would find a "good" set eventually. Alas, that not happen. Having also read about similar issues throughout the 650-950 TOC LCD TV line, I came to the sad conclusion that a Samsung LCD would not make it into my consideration set after all.
However, recently I stumbled upon Samsung's new LED TVs, specifically the UN46B7000/7100. I love the looks of it and the in-store display quality, however, am being cautious after my last experience. So I'd like to ask the forum and Samsung techs whether these TVs are plagued with the same issues as the 6-9 Series TOC TVs, or have those light-related issues been resolved in these new LED sets?
Any feedback will be greatly appreciated. Thanks in advance.
