I just purchased and received the 52" 850 from Amazon.com and I am noticing a clouding issue in low light situations. It is extremely frustrating to pay such a high price for a set and to experience such an issue. Is there any easy fix to this? Is Samsung addressing this problem?
blazinbee,
Can you describe the clouding issue a little?
Does this happen on all inputs, or just television or DVD or Blu-Ray?

i verified this occurs on all inputs: HDMI Blu-ray, HDMI DVD, HDMI tv. It seems as though there are patches of light in various parts of the screen. These patches look like clouds and it is very distracting if you tend to watch tv in the dark.
blazinbee,
Thanks for that. If the "patches" don't move, then that will have to be addressed by a service technician. It sounds like a panel issue. The best bet is to call 800-SAMSUNG and have a service technician come out and take a look.
I wish there was something else I could diagnose, but I'm assuming it's a physical, rather than internal issue.
Keep me posted.

I believe clouding is also known as flashlighting.
It appears to be relatively common in large LCD panels, but apparently some manufacturers have successfully defeated this scourge.

Some people have found remedies, and sometimes it goes away after some period of use.
It may go away after some period of use. Or it may not.
I stand by my recommendation of a service call.

I have the same issue in dark scenes only is it noticable. I have contacted Samsung to resolve. After the set is warmed up for a period of 25 min they are really noticable. When it is first turned on I cannot see them at all. Happens on all inputs or no inputs turned on.
This is completley distracting to me as the overall picture quality of this set is remarkable.
I have the same problem with mine. I bought the set in December from Amazon. I had bad clouding in the corners and a spot off center. I called and a tech came out and said the panel needed to be replaced. They sent a new panel and replaced my old one. This was a fairly painless operation and I was excited to have a good television for my home theater.
However, the new one has worse clouding than the old one. Now instead of clouding in the corners I have clouding in one corner and four big clouds right in the center of the screen. I called the tech again and after messing with it for an hour and calling Samsung he said that it's just tough luck. That is the way that the monitor is supposed to be and that no one else has complained. Ishowed how distracting the clouds were in an episode of Star Trek (they are very noticable during any of the space scenes) and his comment was "pretend they are nebula". Nice!
However, I find it completely unacceptable. I purchased a top of the line model hoping to avoid quality issues. I called again and this time he said he just came from Samsung tech a meeting where they spent most of the time discussing this problem. The new solution was to update the firmware and turn down the back light so it can't go over a certain brightness. It seems to me this would reduce your contrast ratio. If the set won't function at the contrast ratios advertised then it shouldn't be advertised at those ratios. I just want my money back at this point. I have a smaller Samsung (32") which has not trouble and 5 Samsung computer monitors which I have loved. I was very disappointed with this tv. It does not perform as advertised and they are trying to avoid fixing the issue by saying this is just how they are. That is garbage. Plenty of competitors have large LCDs that don't have this problem so it isn't inherent in the technology. It is just a bad design on Samsung's part.
How many Samsung Techs are on this forum?? Every one of their responses are the same!! Stop acting like you have no clue of what us users are experiencing!! Its getting pretty frustrating cause this clouding issue is appearing in most large scale Televisions and seems to be more frequent. Just a heads up, i did notice that the cloudy areas are not consistent in the sense that they aren't there on all movies scenes... I tried moving my backlight down to "0" and can still see the clouds. My first TV had the same issue but the Clouds were on all four corners opposed to now in the Middle of the screen.
I think most of us Samsung TV owners are overall happy with what our TVs can display, its these damn cloud spots that ruin the experience. Can this be fixed with a Firmware Update?? If not, i plan on taking my TV back.
I got my 850 in June 2009, was made in 02/2009 so everything there should be the latest.
Well I have a few issues with my TV
-It resets by itself( it goes off and then back on by itself)
-White Clouds? many
-Horizontal lines on the right side of the screen when playing some commercials in DTV channels.
Samsung tech came first time, replace panel(the old one didn't had the inverters covert, the new one does and clouding is worst)
Result: still the same issues.
Samsung tech came again today, replace main board.
Result: So far TV is not resetting(I have to keep testing, usually is very hard to reproduce)
The sound is somehow better but less power(don't know why)
Horizontal lines, still there.
I believe the clouding is due to too much pressure in some areas of the panel. If you want to reproduce the issue, try applying a bit of pressure to the screen and you will see the clouds.
That could explain why somebody posted that they removed the inverter covers and it got better.
Any Samsung tech can confirm this?
