Hi all

I have recently purchased a Samsung AU46C7000WM LED TV (the 3D one).  Really cool TV.

However, I returned the first one I got with what I believe now to be backlight bleed.  The people at the shop could not see the issue but it was pretty obvious to me in a dark room showing dark images in movies etc.  They did give me a different one.

The one I have now appears to have a darker shade on the top half of the TV than the bottom.  Watching presenters on TV appear to be sitting in the shade.  If you are on the guide page of Mysky the top half is definately darker than the bootom.

Does anyone out there have one of these TVs.  Or can give me some suggestions on setting that could change this.  It is a very good and expensive TV, so if it is not right I want to know.

Thank you all.

That tv has some viewing angle issues so because your particular one has a relatively large screen the angle between top and bottom may give some difference in the picture, does it improve if you stand up a little or bob down?
LCDs can have a bit of uniformity issues some LED tvs have been notorious for this, lowering the backlight and brightness settings a bit could reduce the effect a bit but it's sort of an inherent characteristic of the panel.
If you want to try some settings I put the one in our store on movie mode then used settings something like
Backlight:8
Contrast:95
Brightness:45
Colour:50
Sharpness:0
Much more detailed settings can be found here though they won't be perfect due to minor differences in your tvs and rooms

I'm curious, if you're watching in a dark room how come you didn't go for the plasma model? They generally have much better colour uniformity.

Thanks for the feed back.

I have tried the different viewing angles (bobbing up and down) and it doesn't really change.  I have also changed the settings quite alot (backlight, contrast, eco settings etc) to the point where it is too dark to watch, but the picture is relatively the same. 

I maybe creating a storm in a tea cup.  I really need to know if anyone else sees this.  It maybe the correct viewing picture.  As I metioned I had another TV and it didn't seem to have this issue, but maybe I just didn't have it long enough to notice.

I went for this TV because I read and heard good things about Samsung.  The room is very bright during the day with a window almost facing the TV.  I like the tech in the TV with it's abiltiy to go 3D.  The 200Hz motion plus (this was import because my last TV was a Philips 200Hz natural motion TV, and though old tech now, produced a very good, smooth picture that I had not really seen better until now).  I could go on...

Cheers

Ok, so it just sounds like there is a lack of uniformity in either the panel or the backlight, not a huge amount you can do about that short of returning your tv for another example until you're happy with it.
It's your call as to how picky you want to be about this sort of thing, no tv is ever perfect but on the other hand you did pay a lot of money for it.
As for myself seeing this I spend a lot of time in front of a lot of tvs so I notice little things like this, it's not the correct picture as such but I've never seen a tv with a 100% correct picture and I never will and most flaws are only really apparent when viewing next to other tvs.

Cheers.  Really appreicate your feedback.  I also spend a fair amount in front of the box.  Your comments are spot on with picture quality.  I will probably live with this knowing that backlight bleed can potentially be more of a problem, and can't guarantee better with another TV.  At the end of the day it's still a bloody good TV.

There are other 3D TV's coming. Given the lack of any 3D content you have time to get this right, especially given the price at the moment. Perhaps you may be better waiting for the Panasonic Plasma TV's if you're having issues with an issue inherent in an LCD TV.
