Well I got a new imac this one is week 52 and the tinge doesn't seem to be there but this is the first 10 minutes of it being on. The camera has less stuck pixels then the previous one and the screen doesn't seem to have any so so far so good.
Got a tip for us?

My replacement Week 52 27" landed on my desk and hour ago, and it's got a yellow tinge towards the bottom. It isn't *too* bad, but as I'm using the iMac for medical imaging, it's going back.
Yet another yellow iMac
Got my replacement and it's also yellow. This time, it's yellow from left to right. Forgot to see what week it was.
This will be my second return and I will be waiting for my fourth iMac now.
These are minor defects and it's possible we are all being a bit anal with it, but I don't think it's wrong to expect perfection in a $2200 machine.
That said, Apple has been extraordinarily responsive so far. Even got a gift out of it. (Would prefer not to say what it is and potentially get my rep in trouble. It was <$100)

Hmm....
Used your technique for this pic - shot a plain white background with a 5dMkII/24-70f2.8 and checked the temp difference w/LR2. If anything, the screenshots under represent the actual color shift.

Here's a photo of my 27" i5 (Week 51). While not perfect, it is certainly "acceptable" to me and looks absolutely fantastic other than the very slight color gradient. I've had the computer a week and it has been on 24/7 (including a few reboots for updates and booting into Boot Camp).
The photo was taken with a Panasonic GF1 and the only modifications performed were cropping and resizing. By the way, it's difficult to take a perfect straight-on photo of a 27" screen, I've discovered! LOL.

This looks very acceptable to me also. Thank you for sharing the photo and I hope you enjoy your iMac.
Some testing needed.
Although it has been reported previously that external displays are not affected by this issue, however, Apple Cinema Displays exhibiting this behavior is something entirely different.
Anyone else with this setup care to help verify this? Those of you with other external displays can help as well. But it might be only the ACDs exhibiting this kind of problem.

2nd computer, week 53, worst one I have seen in person. I am really bummed.
Huge triangle shaped dinge on the display, otherwise it is in really great shape.

I took this shot and cranked on the saturation to see if it amplified the colors in the same manner I was seeing them. Sure enough.

MacHysteria
I am a Windows user wanting to make the switch to a 27" i5 iMac. However, I have held back from purchasing one because of all the comments on this website about yellowing and other apparent defects.
I haven't seen any actual units with the problems. The ones that I have seen in stores look perfectly fine, but they may be early production models which are not defective.
When I look at the images some of you guys send, the problem doesn't look that bad.
I bet that if no one had mentioned it, half of you wouldn't have noticed any problem at all. I think that the power of suggestion is behind this to some extent, creating mass-hysteria among the truly obsessed. I bet some/many of you are neglecting your spouses or not sleeping nights thinking about it. Kiss your spouses, not your Macs. Those of you who have returned units to the store more than three times may need the kind of personal help that an Apple genius cannot provide.
Anyway you've influenced me and I'm holding back for now. Shame, because I'm dying to get my hands on one of those things.

Got a 21.5" iMac for my birthday today, it's a week 38 (must have been one of the first) and there's no yellow at the bottom of the screen. It's perfect! It gets a little hot sometimes, but that's the same with all iMacs. The only time that there ever cool is when they're turned off!
I also received a call from Executive Relations and returned 2 27" iMac's to the store, which were both sent to Engineering to look into the yellow tinge/tint issue. I am on my 4th iMac and it has a slight tint and I am holding onto it until Apple quietly fixes it or publicly fixes it...
I emailed Steve Jobs and got a call back in a day or two... I was speechless...
I didn't go looking for the yellow tinge, but having run my i7 for a couple of weeks now its quite noticeable on the MacRumors website. (I'll hang onto it for now, but its going back at some stage - hopefully when Apple have a better idea of what the problem is)
You might want to wait a few weeks before deciding if the screen is OK or not. I wanted to avoid a whole set of visual tests when it arrived. It only became an issue for me when I could see it in day to day use.
If you don't think its an issue why not buy one? IMO the "truly obsessed" Apple users are on this site telling everyone with a problems that they are delusional and/or trolls. I have a 24" iMac and its fine - I have a 27" iMac which I bought because I wanted it for its amazing display. Do I want it to be fine? Yes. Do I enjoy buying defective goods? No. Does having a substandard product to complain about bring me joy? Hell No.
I've been a PC user for the last 15 years and want to make the switch to an iMac. I've been reading this site (as well as many others) to become a more informed buyer of this product.
After waiting patiently for the iMac 27" update, I was ready to purchase one but have gotten cold feet as I am horrified by all of the complaints with the screen.
I'll wait a little longer for Apple to fix this issue, otherwise I will have to buy another PC. My fear is that Apple quality is no longer adequate and they will only come down to the PC level of reliability.
Its a real shame with these yellow tint issues and screen flickering. To think I almost spend $3000 on their top-of-the-line iMac is scary for me to think about. I don't need these return hassles, especially when the replacement is either worse or has more problems. Verydiscouraging to hear.
I've lost a lot of confidence with these apple products. I think the iPhone is the last Apple purchase of mine for several years until I see some QC iimprovement. Such a shame. There are MANY MANY people like myself who want to permanetly migrate froma PC to an iMac, but will hold off entirely due to this screen problem.
I can only hope that Apple fixes this screen issue ASAP, as they are losing customers in droves.

To Industrial Space: I'm with you on this one. I would have been a 27" iMac owner by now, despite my reservations about switching before Outlook for the Mac arrives in late 2010. (iCal is extremely weak but I would try BusyCal, and mail.app is not great.)
Microsoft Entourage comes with MS Office on Mac and is equivalent to Outlook: email, calendar, notes, tasks, contacts.
I've been using it for 5 years instead of mail and ical.
Good luck getting Entourage to sync with a mobile phone. I tried in vain (using The Missing Sync for Windows Mobile and The Missing Sync for iPhone) to get consistent, accurate syncs and had nothing but problems. I moved to Apple Mail and iCal and guess what? They just work. Hopefully MS gets it right with Office 2010 for Mac because I do miss some of Office's advanced PIM functionality.
Now, back to our regularly scheduled thread...
Just tested my screen. And I am wearing my glasses, and I seriously can't see any difference between the top and bottom bars.
I asked my friend to check it out too, and she said that she doesn't see any difference.
I guess I'm the few who got a good working, flawless iMac

This thread is now in the hands of PC users, milking the subject for all it's worth. Go through the last posts and see them all agreeing with themselves (all fellow "newbies", notice) about how they were going to switch to Mac but, lo and behold, they've now changed their minds.
Pitiful. No better than when one manufacturer gets a gang of posters together to give bad reviews to another manufacturer's products on the Apple Store website reviews.

got a week 52
I just got my week 52 i7 imac 27" replacement yesterday.
no dead pixles, and everything was perfect.
BUT
There is still a yellowish tint on the bottom of the screen.
its more "even" yellowish tint this time. it blends more to the cooler top screen. Hardly noticeable if you don't really at it for a long time.
It DOES gets worst after almost a full day of use!!
yellow become more yellowish compare when it just out of the box.
I'm keeping it for a week see how it goes. My girl friend can even tell the difference. i'm thinking, I'll just use top of the screen for editing my photos and use bottom for surfing the net. Since the screen is big enough to do that.

Man I went through the same reasoning before I bought mine. They can't ALL be that bad right? Well I was proven wrong. It is certainly NOT the power of suggestion, when you have docs and work open and you see a giant gradient going from white to "pee yellow." It's a bit distracting! My first one had strange blue coloring in the upper right corner as well. After a month of dealing with faulty units, I got my money back.
It's fairly insulting to insinuate people returning macs give more love to their machines than people. Actually, if that's what you really think I would URGE you to go spend more than 2000 dollars on an i5 iMac. There is a chance you would get an "ok" unit, but there seems to be a larger chance that you will get what everyone else is experiencing. I would be curious to see what your reaction to that would be.
