I have one of the Original 27" Imac's with the yellow tint problem. It has bothered me much, but they had told me to hold tight, and I could get it fixed in the future. Well, the future is here, and I was going to take it in and get it fixed, but wanted to make sure they have remedied this problem before doing so.
 
This has been fixed with a firmware update for quite a while now.

I've bought a 27" iMac i5 several weeks ago, and it never showed that problem even without the firmware update. But I must add that I purchased a computer from the show room, so I was 100% sure that the display was perfectly in order.

Anyway, I think it's generally perfectly safe to purchase a 27" iMac now. In doubt, go to a store, ask for a demonstration and purchase exactly the computer that they showed you.

Of course, you can also wait for a refresh - which nobody can tell you when that might be and what problems the next generation of machines might have.

I'm not really looking to purchase, just get mine replaced or fixed.
 
If your not happy with the screen and apple is offering a replacement than you have nothing to lose by getting it replaced.

Is the Yellow tint problem solved? Depends on who you ask....
 
Re solved or what the cause is/was, I have no idea, but I can report my 2-week-old (or thereabouts) 27" i7 has no visible yellowing.

Firmware cannot solve physical defects with a monitor. :rolleyes:

There have been reports of yellow screens still being out there. Though the complaints certainly seemed to have dropped off. Either people gave up and moved on, or the screens have gotten better. Not sure because after my two bad units I went back to a regular external monitor and a mac mini. Still waiting for a decent desktop to be released by Apple.

The problem was "addressed", but some people still report getting yellow tint (usually as a surprise out of the box: "What? The yellow tint was not fixed yet?").

You are probably out of luck for straight replacement (two weeks?). To fix the problem they replace the LCD panel, with reported hit and miss results. They apparently still don't test panels for yellow tinge and some people reported worse tint after the replacement.

To be fair, Apple seems to have an extremely liberal approach and will try to fix the yellow tint problem again and again, until you are happy, so dust off your other computer in the meantime, since it all takes time...

as far as I'm concerned, the answer is no.

I just purchased a new 27" imac dual core model yesterday and mine has the yellowing issue in the lower right hand corner mostly. This is after I got the computer up and running and did the most recent update. It also has 3 or 4 good size specks of dust sandwiched between the glass and LCD, so needless to say it will be going back for a new one until I get one without factory defects.
 
My 2 week old 21.5 has yellowing...i'm willing to live with it it's not a show-stopper for me...

-J.-

Mine has a barely noticeable level of yellow tint at the bottom, it is almost impossible to see it unless you really look for it, and have the screen entirely white. Def not a deal breaker for me. It is an amazing machine. My SR MBP also has a vague yellow tint.
 
Misinformation!

This is incorrect information you are providing. PLEASE verify things before you post.

Firmware did NOT fix the yellow tint NOR was it supposed to. It addressed other issues.

Recent iMacs STILL have the yellow tint issue.
 
My iMac i7 has no visible yellowing. Don't know if there in fact is yellowing present on my screen, but I can't see it so I'm happy, great machine.
 
I went through two, and looked at a third instore within the last month. I finally gave up and got a full refund. Really disappointed as I absolutely loved the machine, but it was hopeless to try and use it for photo editing, the yellow tint was obnoxious.

Almost two months later and it is still a problem. 27" i7; I had severe backlight bleed, had the display replaced, picked it up yesterday, and that problem is mostly gone. But now I have the yellowing.

Apple, what's going on here?
 
These threads got old a long time ago. We all know the displays vary from one to another. Back in February I purchased a 27" and exchanged it 5 times and ended up with a refund. I purchased a mid 2010 i7 a week ago and guess what: it's perfect. And I'm very, very picky. Some get lucky, some don't.

To sum it up: it's a game of chance. But they ARE out there.. somewhere.. :D
 
Im on my second 2010 i7. My screen has yellow tinge, but it is uniform throughout the entire screen with slightly more on the bottom inch of the screen.

It is not nearly as bad as some of the late '09 panels.
 
LED is the problem

I have i7 quad core.

If I look closely I can convince myself of yellow tint. I can do the same with my iPad- held in different angles.

White in LED display is not as clean as in my previous LCD iMac G5. I guess this is where yellow issue is from(LED). It gets worse on 27" because of the screen size and viewing angles.

It is not a dealbreaker. This machine is lightning fast and quiet. Temps are cool.

My guess is the yellow problem is inherent problem with LED technology. Correct me if I am wrong.
 
My new 2010 i7 iMac screen is still unacceptable to me, but it's nowhere near as horrendous as the 2009 i7 iMac it is replacing. I imagine this is about as good as the screen gets, after my analyses here (Post 1, Post 2) ... I imagine my screen looks "perfect" to most of the people on here claiming such, but to me the screens look more like the second image (first post, the saturation is boosted) in person.

I have to move my browser down two inches from the top to avoid the "dingy" feeling. It's worst on whites and light greys. I can counter it some by moving up the white balance to 7000K (from 6500K)

I got it 4 days ago, I'm still trying to decide if it's worth trying for a replacement. I could get a worse screen, after all.

My guess is the yellow problem is inherent problem with LED technology. Correct me if I am wrong.

After seeing the vastly different properties of my two screens, I would say it's likely inconsistent color temperatures among the LED array. Seems like matching up LEDs by color temperature before sticking them into the panel would be a good idea, though. Don't know why the panel manufacturer wouldn't. (Probably costs Apple an extra $1/panel)

Small correction: The Apple LED technology.
There is a number of large screen LED HDTVs on the market with no yellow tinge.

i can see yellow tinge if i see very closely with that specific test only, in normal operation it is no issue, i have only noticed it when i looked for it, you will be surprise there are many issues with LCD screens from clouding to uneven brightness, there is no such thing as perfect LCD, the flaws become more visible with screen sized going more than 20 inches.

I have gone through many issues with LCD in Samsung, SONY XBR line (well over $5K price), The real deal breaker is dust issue in screen in IMacs, that is pure quality control. Apple have to do a better job in QC if they want premium money.

Apple is good at acknowledging tint issue and many customers have their sets replaced multiple times.

What makes me angry when you buy premium product and manufacturer gives you run around for their quality issue, that is not acceptable in my opinion.
 
Shrug...

I was a graphic designer for years and was very anal about subtle variations in color because I had to be for my career.

I got an EXTREMELY late Corei7 2.8 27" machine on 6/26 (can anyone give me a clue how to check WHEN and WHERE it was built based on serial).

The screen on this is as close to perfect as I could hope for - no perceivable yellow tinting towards the bottom and no "flooding" on the lower right or left corners.

That doesn't mean a problem doesn't exist for others.
 
dust is no big deal

Hi,

As one of the latest victims of the "replacement cycle" (various issues: yellow, dead pixels etc,) with the new imacs and on number 4 at the moment, I recently took matters in to my own hands re:the "dust behind the glass" and once you have pried that glass off and cleaned it (and the bare lcd panel) you will hit yourself in the head for making such a big deal out if it.

It really is *incredibly* easy to take the glass off (suction cup from top) and wipe these surfaces. Considering how common this problem is, and how easy it is to "fix", I am surprised it's not in the "getting started" booklet.

For suction cups, I simply borrowed some from my shower radio but any decent sized suction cup would likely work (e.g., some toy from the dollar store).

If your screen is otherwise perfect and your hardrive is quiet, do yourself a favour and don't send your iMac back for such an easy fix!
