Glad to hear you are enjoying the set. I think the majority of us don't have any major issues. There are always going to be some sets with clouding and flashlights since it's the nature of LCD. Those who have issues just play the return game till you get the one you want. Just remember it's never going to be 100% perfect. Heck I can see clouds under certain conditions on my set but it requires me to jack the backlight in a dark room. I'd never watch the TV that way.

Even though I don't see how a photo of no clouding, could be a baseline against some clouding, I would be happy to post a picture for you. However, I don't know how to take the kind of picture that you want, nor have i ever posted a photo of any kind on a forum before.

Furthermore, what is mild clouding or severe clouding, anyway? Do you really need to see somebody else's clouding to see if your set is any better or worse? Should what somebody else's problem looks like be the final determinent whether your problem is severe or mild? The bottom line is what you think. If the clouding on your set irritates you to the point you can't ignore it, then your clouding problem is severe, no matter what anybody else's display looks like or anybody else thinks.

Frankly, knowing a majority of sets probably have no problem, it would be difficult for me to ignore even mild clouding. If my set had any problem, I would return the set in a heart beat and try another, as long as that option was available to me. If not, I would let Samsung try to rectify the problem. as they have plenty of experience by now replacing these panels.

Seeing as both sets has their pros and cons, I decided to buy both sets and put one of them into our bedroom. Got the Samsung UN55B8000 for $2899 shipped. That was the only way I could settle my doubts about both sets.

I just had the TV tech stop by. He insisted that the flashlight wasn't enough to warrant Samsung replacing the panel. He insisted that Samsung wouldn't replace it.

We made some adjustments that I think have helped
  1. Turn OFF the white LED on the bottom of the panel
  2. Turn down the backlight
  3. Turn Dynamic Contrast to High
  4. Turn the HDMI level to LOW (I think this helped the most)

I was hoping to get my panel replaced but it didn't work out. I think my blacks are getting a crushed with the "Low" HDMI level. I've been messing with the brightness trying to get a happy medium to bring out the dark detail.

Time to sit back, relax, and force my self to enjoy this TV.

Yes. But, I've been through several TVs over the past 5 years (CRTs, LCDs, Plasmas). This is the best TV I've seen to date.

Overall, I'm happy with the set. It's time to order my Blu - Ray and enjoy the the picture.

P.S. I've found that adjusting the gamma (and brightness) in Standard lets me reduce black crush but maintain the deep blacks/minimal clouding that I'm looking for.

Honestly, the TV isn't broken. I was just hoping for the perfect TV - Guess what... it doesn't exist.

I just pulled the trigger and ordered the LN52B750 from Big River. Awesome deal combining the GB trick and the promo deal. Now the wait begins until I get the set next week. I went in this afternoon to my local dealer to check out the set for the first time. Set looks great and picture was awesome. Can't wait to feed it HD and Bluray material.

Here are some examples of my uniformity issues. Are these considered bad or standard? If I would like to get a new set from Amazon do I need to contact Samsung first? Also, do I need to package the tv up myself for pickup? I'm not sure I can get everything back to how it was when it came. Thanks for anyone with experience with this.

First 2 were head on, last one is at an angle.

To me that seems excessive. Have you wiped 'er down w/ a lint-free microfiber cloth yet? I'd try that before packing it up or calling Samsung.

Thanks, no I haven't wiped it down yet. Can I use the cloth that comes in the packaging? I did try loosening the screws in the back but apparently that didn't do much.

No way it looks like that in person unless you have the backlight jacked. What is the backlight setting?

I used a soft microfiber cloth, but I'd think the one that comes with the set should work fine.

Nah man, it's a good set. Don't let some so-so experiences get to you. The clouding issue is an interesting one. For instance my set has a hint of clouding. I can only see it on a blank input at a very high backlight setting. However, I'd never watch TV that way so it becomes a non issue. I realize it is for some but I think at this point everyone knows to get a 100% cloud free set is impossible. Go plasma but even that 111FD Kuro I had wasn't uniform on a blank input. Some areas of the screen where darker then others.

Don't get me wrong..the picture is outstanding. I'm just getting annoyed and probably hyper sensitive, because every dark scene now my eyes go directly to a certain area of the screen with clouding. Maybe I will get used to it if I don't end up with an exchange. If the amount I posted above is considered "normal" I can live with it, but if people are getting perfectly uniform sets like some have stated, then I'd like to look into an exchange.

But do it at night so you can tell immediately if there is any difference. Don't do it in the middle of the bright day like some. They had to wait until it got dark at night to see if there was a difference. Immediate comparisons are preferable. If you can take a photo before and after, even better.

It's always nice to read the observations of people who actually have two sets side by side in their home for comparison. At least I hope you set them side by side before moving them to do a different room. Anyway, please detail the advantages and disadvantages of both the B750 and the B8000. Many people will be deciding between these two, and will want to hear your thoughts.

Cheah !!!!!!!

the GB trick worked!!, got it------from BB I know all that and i get it from the local BB. OK, i got it for $2041.99 plus taxes. BUT here is the catch aka the fun part. the manager gave the me the harmony one remote for $125(original price $250) and the samsung BD-P3600 for $300(original price $400). AND he told me he will give me some great deals on the audio (receiver, speakers,etc) stuff when i come back. DAMN i don't know enough about receivers, i would have got them too.......suggestions?? Thanks !!!!!!!

I'll bet the flash drive models were the earlier ones shipped and the manual wasn't printed yet. At the same time, maybe there were some earlier adjustments (maybe to gamma) to increase detail in the dark areas. So there is no free lunch. It could be that there is a reasonable link between the two issues, but doubtful that the manual type is a perfect indicator of the clouding/darkness.

I'll set up my 1st B750 (which I haven't returned yet) and take a picture with both units in view. That way you can see that the severe clouding on unit 2 is not some artifact of the photography.

OK, here is my shot, as you wanted it: 1/6 second, F5, 1600 ISO. My 24-70 f/2.8 lens was fully extended to 70mm. My impression is that it looks just like this if you make sure the laptop screen is tilted towards you enough. About 10 (?) degrees closer towards your face than dead-on perpendicular is closest for me. If tilted back too much, the laptop screen shows it as pure black and in reality it does NOT look like this. And my flashlighting is back (upper right). I cropped it a little less tightly this time so you can see the background.

I think this level of variation seems acceptable...I mean, it doesn't seem excessive.

I know exactly what you mean by being sensitive. For instance I got rid of my 111FD because "Dirty Screen Effect" was noticeable. It wasn't the worst thing in the world but my eyes keep drawing to it and ruined the experience. These TVs aren't a cheap purchase for most people. At the end of the day it matters what is best for you.
