SR MBP LED LCD yellowish and gradients issue

I just grabbed one in N. Michigan Ave Store Chicago on Monday, it was a week 21, and samsung, of course with yellow tint problem! It was 3rd one, and now waiting 4th one from china.
hurriance, did you get your computer? Does it have the yellow tint?
I returned my MBP and I ordered a new one online. If it isn't perfect, I'm getting a thinkpad.

My second one had the yellow tint. I talked to the Apple Representative and he recommended that I send it to AppleCare and that they would replace the screen and guarantee it to be perfect. Lets hope it's that way
How to get AppleCare to care?
How do you get Apple to acknowledge the problem and exchange the machine? My father's new 15" SR MBP (with the LED-backlit screen) has the same problem with the bottom part of the screen being yellow. The nearest Apple store is a 5+ hour drive away, and over the phone Apple says they've never heard of this problem, and suggested that he zap the PRAM! They won't accept an exchange. The machine is 3 weeks old.
I'm very disappointed in how Apple has treated him.

The computer being three weeks old makes things pretty complicated, since Apple has a 14 day return/replacement policy. Keep calling Apple Care until you get someone who is listening to you. While they may not (or they may, who knows) offer a replacement, they may try to repair it. I don't really know if the repair works though. I heard someone say they got their computer back from repair and it had the same problem.
Here you go: above is a plain white canvas in Photoshop, full-screen. This was taken with a Canon EOS 30D on auto white balance settings. My monitor is calibrated to D50 using Expert Mode. You can clearly see a very uneven bar going across the bottom 1/3 of the screen. But overall it is just very uneven.
Even on the default color profile, it looks the same, don't worry. It's not the profile. But I'll post a pic using the default profile if it will make your brain happy.
PS -- The weird color banding that you see (red/green vertical banding) is not visible during the use of the screen. I suspect it is an artifact caused by the fact that the shutter-speed of the 30D (1/100 sec) is fast enough to capture the refresh rate. But the brightness variations are clearly visible to the human eye.
UPDATE: This is a Samsung screen I have, BTW.

Thanks. I can definitely see the yellowishness in the lower right part. As for the uneven illumination, I think it's pretty good compared to the older MBP displays.there's obviously some darkening in the upper corners and in the lower right corner, but I've seen much much worse on the older ones.
What is there to say, except that the displays are just not as good as desktop LCDs? I think the increased brightness (these are around 300cd/m2 and in some spots even more) and good contrast compared to the older powerbook displays brings out the limitations of the technology as it is today. Most PC laptops look better in terms illuminaation distribution, but they're much dimmer when measured objectively (usually around or below 200cd/m2) so the flaws don't stand out as much. Maybe that's why PC manufacturers don't push it when it comes to brightness. Notebookcheck.net measures the display brightness in 9 quadrants in their reviews and the current LED MBP are the brightest around.

Hi all,
New MacBook Pro (SR) owner here too. I noticed this also, and immediately color calibrated the screen with my ColorVision Spyder2 (a color meter that attaches to the LCD and communicates to the computer about what color it thinks is displaying and what is actually being displayed). This resolved the yellow hue. I think the color profile shipped of with these machines are just off.
Put the following file in Macintosh HD/Library/ColorSync/Profiles
http://www.megaupload.com/?d=HFQ5B8V8
Then go to System Prefrences >Display Preferences > Color > and select "PhotoCAL Profile 7/14/07".
Hope this helps. Note: I performed the color calibration on full brightness, so to get the added color accuracy, you'll need to also set your LCD to 100% brightness.
If you really care about color accuracy, you need to perform monitor calibration on your own monitor since your monitor may be from a different vendor, as well as each lcd is unique. Not to mention that the lcd drifts every two weeks. Color calibration is a routine operation every two weeks if color is critical.
Where to get color calibration devices:
ColorVision Spyder http://www.colorvision.com/product-mc.php
Pantone Huey http://www.pantone.com/pages/products/product.aspx?ca=2&pid=79
Again, I have to stress that the color profile I posted was generated on my machine, on a certain time and date. The color accuracy of your monitor drifts frequently, and the only way to work in a correct color environment is to re-calibrate every two weeks.
If you are just needing a more pleasant viewing experience, try manually calibrating:
Open System Preferences > Displays > Color > "Calibrate..."
Then place a check on "Expert Mode". Follow through the assistant.
When prompted about "Select target gama", I recommend 2.2.
On the page "Select a target white point", uncheck "Use native white point", and move the slider until you are happy. 5000 will produce a very yellow hue, while 9000 will produce a very blue hue. Find a happy median.
Continue and finish the assistant.
Hope this helps.

Quoted for truth. There is an enormous difference between the default profile and my calibrated one. The response curves in "Color LCD" are way off.
The use of a colorimeter such as a ColorVision Spyder or GretagMacbeth Eye-One will not correct a display that exhibits yellowing in the lower portion only. It will only correct a display that has uniform color inaccuracy. Believe me, I've tried.
Do you have a samsung screen or LG?
I tried your link but was unable to download the file..... Any ideas what I may be doing wrong?

UPDATE: This is a Samsung screen I have, BTW.

This is just my opinion but this screen just looks like uneven back lighting to me. The top and bottom in this screen look pretty similar although its a little worse/uneven on the bottom. The previous screenshot with a grey background was taken at an angle so that one looked a little worse off.
I haven't gone through all 29 pages but we definitely need to see more photos from those who have returned their MBPs multiple times or a side by side comparison in your local apple store that illustrates the difference between a "good" in store MBP versus a "yellow" one.

Screenshots, Shift+Command+4? You won't see any yellowish tints...etc. You are asking for photos. Anyway, i have one on my blog.
You need to follow MegaUpload.com's instructions and enter the three letter code and then wait 45 seconds for the download.
My LCD is Samsung. So calibration corrected this yellow color.
I dont see anything wrong with that image on your blog. Is the screen on your replacement better?
On his blog, http://www.liuding.com/blog/uploaded_images/LIU_0002_1-794922.jpg
The screen is yellow towards the bottom.
Are you sure you can't see the ugly stuff at the bottom of the screen? The page 14 testing images were really cool, I spotted the problems right away.
The second one will be here on Monday before noon. I will photography the screen with my Nikon D200. Indeed, I'll let you guy know.
I just ordered a macbook pro late friday night, and somewhat new to mac and this site and I customized my hard drive and now Im terrified of getting a bad screen and ultimately getting stuck, is it possible if I call in that it wont be a huge deal to changed to the regular model on the website, its sunday at noon and obviously nothing has shipped out notebook-wise and such, please I'd appreciate any advice as Im obviously getting worried about the issue. thanks.
Ok got my macbook pro back from repair. They replaced the LG screen with a Samsung of all things. The screen has the yellowing AND it has HORRIBLE flickering constantly. The flickering doesn't go away. This is by far the worst screen.
On top of all that, the repair people scuffed the aluminum lining for the screen so theres a cosmetic scuff that is very sharp to feel. I really should have exchanged it instead of sending it in to repair. Now all I can do is get it repaired till I get a decent one and then ebay it and recoup as much of my money as possible.

Sorry to hear that. How awful! Did you get it at an apple store recently? If so, it doesn't matter if it's been repaired if you're still within your two weeks. Just take it in, show it to a manager and say it's not working properly. They usually don't check if it has been repaired. Just don't go to the genius bar because then they'll put in your serial number and might cause trouble.
