i read and assumed that the clouding would be gone with led backlighting as it's usually caused by the fluorescent backlights used in early lcd's

my bravia supposedly has this , but i can't say i've ever noticed it

not being in the habit of watching a blank screen too often..

My 10 had the same problem. I asked my dealer what this could be. The dealer told me the spots come from the machine which places the screen in/on the BV10 by using "suction units" (?) Anyway, during a few days these lighter areas disappeared totally.

I had the same thing on my BV7-40 MKIV. Dead easy to fix - as you said, it's 'dirt' or similar from the machine used to handle the glass.

Why not just give the screen a clean using LCD wipes or something? I did.

yep! lets hope this is the case with the panel's. will keep an eye on this over the next couple of days and post feedback on if i've just been unlucky with a bad panel!!! The t.v itself is great though! the picture on just sky hd (non hd) is amazing, and by far the best picture i have seen on a t.v in both standard and high def. It's just the dark areas of the screen which are bothering me! As also said in this thread, if it was a sony or LG t.v i would put up with it! but not at the price of this t.v!!!!!!!

Is the panel used in BeoVision 10 the edgeLED 200Hz panel from Samsung?

They have reportedly been largely free of clouding problems, which Sony has lately been infamous for. Of course there can always be a few bad apples in a patch of LCD screens, exhibiting notably bad clouding.

For a TV costing 6k, I'd hope that B&O quality control picks the bad apples out, and never lets them go into a BeoVision 10 assembly.

Also, the explanation of "suction units" being the cause for temporary clouding is a viable one: usually clouding is a result of a mechanical stress on the panel. On some Samsung LED-TV units clouding could be cured simply by ever-so-slightly loosening some of the screws on the back of the TV. They were screwed into place too tight at manufacturing, and the supporting frame was putting pressure on the panel.

So Paul's comment was a relief -- and I hope any clouding disappears in other cases reported here as well.

It would be unthinkable to have a "panel lottery" with BeoVision 10 (or any B&O TV), where you either get a good panel, a panel that is slightly but tolerable cloudy, or a panel that is simply hideous. I've never heard of any clouding issues, or seen them, on BeoVisions, which has always made B&O "a safe buy" in this respect.

While on the matter, it's worth mentioning that Philips, Sharp and Panasonic LCD panels are famous for being most cloud-free altogether. Sony and Samsung have partly joint manufacturing, explaining why they both have had issues, with Sony panels taking the cake for the worst cases. My understanding is that Sony has lately fixed the manufacturing issues though, at least for their higher-end models.

I suspect that at a time of this economic downturn, manufacturers are less likely to trash panels unless they are really bad, and hence more issues end up in people's living rooms. What is considered to be "within tolerance" with clouding, is an interesting question. For a high-end television, there should be no tolerance: either a panel is cloud-free, or it isn't.

Sadly, with many lesser brands there is too much gray area in between. I personally find it appalling that some manufactures try to pass clouding as something that is "inherent to the technology", when it most certainly is not, with proper quality control.

I for one am hoping for clear and pitch black night-skies (okay, screens) and no clouds for everybody :)

Our BeoVision 10 was delivered last week.

I also noticed this "clouding problem" similar to your picture posted.

Asked my dealer yesterday but he was not aware of this problem.

I am also not sure if that is normal for LED edge lit screens.

Will fiddle with the picture controls later maybe it helps.

Mine does not appear like that though I suppose digital cameras may make things look different - I'll have a go sometime myself!

blank screen before the film starts!

Well i CERTAINLY hope that this is a fault, and is not the way the screen looks when blank. Look at those patches of light! > That's woeful

You can tell when the screen is on but I am quite impressed with the blacks. There is also some edge bleed which I believe is due to the edge lighting system but I have not found this distracting.

It was very common on Sony TV's of the last year or so - although, if I remember correctly they denied it was ever a problem although many folk returned there TV's to their dealers becuase of it. There was a lengthy thread about it on the Whathifi forum (W4500 sets I seem to recall).

Start by setting contrast, brightness and colour midway and then reduce the contrast until you think the black is acceptable and then adjust the brightness/colour and see what you can achieve.

(This is not from experience btw, it just seems a logical starting point)

i have had a go at changing settings and will continue to try and make it better. If no change its going back! will also try and take a picture that shows it up later tonight. I've also looked on the internet and it seems that the term is called 'clouding'. something that can be common with lcd tv's. however not something you expect from a t.v that cost 6K!

Do I take it you've fiddled with all the picture controls and still can't get a picture to your satisfaction?
