27", 21.5" iMac Owners, test your screen for yellow tint issue here

[TennisandMusic]

Ugh, STOP with the optical illusion baloney. That is NOT what the problem is. These are physical defects on the panels. Discoloration is visible from any angle, and the patterns are DIFFERENT across panels. Is that not clear to people? If it were an optical illusion, this sort of thing would be visible on every monitor in identical fashion. This is certainly not the case, and I can think of no known phenomena that would cause this sort of thing.

These are bad monitors, period.

We just have to wait for them to get sorted out, unless of course you are willing to live with defective products at premium prices, that is certainly your prerogative.

The 27" iMacs are a beautiful thing but they're just not ready yet. Good luck and Happy Holidays everybody.

Speaking of "ugh", please stop with these generalizations. The 27" iMac YOU had had problems. I love how people transmit their own bad experiences to the entire world at large as if there's not even the slightest possibility any 27" iMacs are flicker-free. That goes equally for the yellow tinge deal.

Agree entirely. There is no way to skirt around this or call it anything other than a defect. It may be subtle in it's effect but that doesn't mean it isn't a functional problem that deserves fixing.
I've just returned mine and if the next one arrives with the same defect I'll return it as well and I'll continue to do so until I receive one that doesn't have the problem.
Apple *will* sort this out. If you're willing pretend you don't see it then that's fine but I'll be enjoying the consistently coloured monitor at some point even if it takes several iterations, phone calls, and trips to the post office.

Pretend I don't see what? The yellow tinge that doesn't exist on my i7? That won't be necessary.

Hey, best of luck to you. I hope you get that perfect screen one of these days. I'm rooting for you.

Hate to admit it, but the truth must be told, however painful to admit... there now IS a clearly-seen yellowish strip covering an area of about 1" across the whole width of the bottom of my screen. But it fades out rapidly and there is no yellow at all above that. It is an area corresponding approximately with the height of the dock.
Perhaps interestingly, this has happened within a day of downloading the graphics card firmware update.

While I am extremely grateful that my i7 doesn't have color uniformity issues I certainly wouldn't hesitate to admit if it did.

I returned my former mid-2007 24" iMac several times for screen issues, including a horrible left-to-right gradient problem.

As for the firmware update, since I've got nothing to fix on this iMac I have thus far declined to run it. That said, I fail to see how it could either cause or cure backlight-related color uniformity problems.

I'm sure that it won't affect your work in audio so just live with it... as you have told others to do..

might sound mean but I'm actually pleased!

I certainly give you credit for honesty, even if it's painful. I do the same. My position has not changed so far: I believe there are defective panels out there, though perhaps not all. As I said yesterday, I personally saw a 27" at Best Buy that absolutely, positively did not have any yellow tinge issue. Of course, I can't guarantee that it won't develop one at some point, but so far it's perfect.

I'm hoping that Apple will get control of the issue - I strongly suspect it's a problem with LG's manufacturing process, so Apple can only do so much - they can work with LG, but ultimately it's LG's engineers who will have to solve the problems. This is not an issue of firmware updates, IMHO, cause I've seen this in monitors hooked up to Windows boxes.

UPDATE: good news! ?

ok, so i posted a few days back about the yellow tinge on my week 46 i5 27" imac.. i went to the store today.. i asked for a refund, and gave them the details.. they had never heard about a yellow tinge in imacs (funny how we know more than the genuises about their own product) .. anyway, they set up my imac, and the yellow tinge was there, but less noticeable in the bright lights of the apple store.. but no question it was there... after a few of them looked at me like i was crazy, one nice girl noticed it..

although most of them saw no problem, they offered to exchange the unit.. it was a seamless exchange, and they said if i have any issues with this one, to feel free to bring it back.. they lengthened my warranty 15 days, and i took it home.. i plugged it in, and guessss what.. no yelllow! to someone else it wasnt a big deal, but it was ruining any enjoyment i would get out of my new machine.. my girlfriend who noticed the yellow in the last unit confirmed it wasnt in this one.. this one is a week 48 ..


keep in mind, this is just the first night i am using this.. i have been on it heavily from noon to about 8pm, and the display is holding up, as is everything else. so overall i am very pleased with the service i got.. it wasn't a big pain, aside from carrying it in and out.. so dont be scared to wait to exchange yours.. there are good units out there.. and the inconvenience is worth it.. a perfect defectless machine is a beautiful thing..

Interesting that you felt my comment was directed at you. Surely anyone without the problem or an experience relating to the problem is wasting their time in this thread.

Why would I not assume it was directed at me? You made a blanket statement that you either have the problem or "pretend you don't see it".

Au contraire, for the benefit of those who post to this thread as potential i7 buyers who are scared by these reports of yellow tinge, as well as those who have gotten a yellow tinge machine and are on the fence about replacement or refund, I think it is absolutely not a waste of time that I, and others with non-yellow screens put in our two cents, thank you.

I agree with you that there are some problems with the monitors, but I am certain that Apple will take care of the problem.

I haven't looked today, but yesterday I read a lot of posts from 50-week iMac buyers reporting that their new (week 50) iMac's are OK now. I don't really know, but will be able to tell by today when my 21.5" iMac replacement arrives. I will post in here in a day or two.

I became aware of the yellow tinge when reading about this problem on this and other forums. But instead of testing my iMac's screen with the gray-color strips posted in this forum, I opened the Apple home page (solid white background), and fragged the corner of the page to fill the screen. The top half of the screen was clear and white, while the lower half (toward the corners) had the yellow tinge.

The Apple technicians were very nice about it, and set me up for an exchange, or a refund. I opted for the exchange, which should be week 50 or higher, and hopefully without the problem.

Its so random, a mysterious mystery for sure. I would say if you can live with the "slight" yellow... hallelujah! I'm done with this squirrel hunt, Ill wait until next Christmas. Ive already decided to buy a kayak with my refund.

 

[ScottFitz]

I'm going to be ultra-realistic. You really have to have a solid lightly-colored background on the entire screen to notice most of it. Once aware of it, however, it'll drive you nuts.

As I mentioned earlier, my third one only has a very slight tint in one little bottom corner. Eventually, it'll bug me enough to go thru the apple fix-it shop. But, for 99% of what I do, it's now a moot point.

They'll fix the issue. Either be patient or return it.

 

[skippy911]

I have a week 41 and can see the yellowing. What should I do? Just call apple and tell them its yellowing at the bottom 3rd of the screen?

 

[tapplox]

Turns out I have some good news and bad news.

The good news is that there have been "more than usual" number of barely noticeable yellow to completely yellow free week 51 iMacs being shipped. The bad news is the following:

Just spoke with an AppleCare rep, and they told me (after about a week and a half of waiting) that the yellow tinge is not a fault of the hardware, rather an "optical illusion." So, it seems that Apple will not acknowledge this as an issue, and we will be stuck forever with the yellow tint...wonderful.

I sincerely hope that the rep was just reading on this thread and was trying to come up with an excuse while waiting. To me, that is some very serious dishonesty that I personally could not tolerate with the company.

This is almost an laughable excuse. So long as Apple does not acknowledge this issue people will be stuck with their yellow displays (if you are not aware, some of us have a much more severe yellowing than the rest). Not only that, when the issue does get worst (and, so far that's what the reports are saying) you'll probably be out of luck.

Of course this is just speculation from me. AppleCare might still go and fix your screens in the future. But for now, looks like they'll be stopping people from doing exchanges.

It's funny when I am writing this on my 24" iMac — a LCD H-IPS panel — with a perfect color uniform screen, on the same desk where I found the fault on the 27" iMac. My Macbook Pro sitting on my left side, a LED TN panel, also has a color uniform screen.

I am not sure what to recommend. But those of you who needed a good display for color related work, you probably want to look at those 14 days much more seriously from now on.


I hope I am wrong, by all means. I really do. This iMac was suppose to be the perfect machine for me. Maybe I'll get lucky one day and get a good one, but even when that happens, it would never fix this sour taste and fear.

 

[AlaskaMoose]

Well, FedEx delivered the replacement iMac 21.5, and it seems to be OK (no yellow tinge near the bottom). This one is a week 51 iMac, not a week 50 as I was expecting.

The first iMac (week 49) only had a yellow tinge, but no other problems I could tell. The new one is just as quiet, and like the old one, no screen flickering nor noise of any kind.

Glad to hear that, I'm thinking about ordering mine tomorrow, hoping it will be a week 51 or even week 52, more likely 51 I guess.

If what tapplox says is true that they might no longer do exchanges though, it's sort of scary to think that my iMac might have a problem, but considering the great support people have received, it would be very surprising !

I called Apple about a week after I bought the iMac, and right away was given the choice to exchange or to get a refund. I would think that Apple would exchange computers within two weeks of purchase. But if there is an Apple authorized store, more than likely they would ask you to exchange it there. I bough mine online. You may want to wait to the day after Christmas, or maybe New Year's, since FedEx and other carriers won't deliver it during the holidays (that's two 3-day weekends). By then you should be able to receive a week 51, or maybe 52 iMac.

My first one came directly from China, while the second was shipped from CA. I was much happier to see that on the FedEx tracking page

This may be too advanced of a concept for you to grasp but:

Not "just me" ≠ everyone.

When you make comments about the new iMacs like "they're not ready yet" exactly what is that, the royal "they"?

 

[lexvo]

Why does it looks like the yellow tinge is always on the bottom half of the screen?

 

[Ecoh]

Why does it looks like the yellow tinge is always on the bottom half of the screen?

That's what I would like to know also. It is there physically, not an optical illusion, because when you turn the machine on it's side the yellow maintains it's orientation with the display. It would be nice if someone who understands this technology could explain what might cause this. I am just like to know how things work.
