Yellow tinge from bottom to top of the screen, 27" iMac

The thread is only irrelevant because there is nothing we can do to fix the problem. Only Apple can. I have to guess your post was pointed at me. But I have never proclaimed myself as king. That is going way overboard, IMO. I always make sure to state that my observations are just opinions, just like everyone else. All I stated was, the Copy & Paste Grey Bar test was a sure way to detect a color variance problem, for those who were not really sure if their screen had an issue. This was suppose to be a post to help people, so posters who just claimed their screens were perfect with no proof were confusing others into thinking Apple is now manufacturing perfect screens. Again, as everyone knows, there are no perfect screens, if you are judging by looking at Grey Bars. As I am happy with my iMac, my intent was never to dictate to people what to do. I was merely passing on information that I had learned only through my experience. I do have an acceptable iMac & I'm keeping it. But maybe this thread does need some new blood. It seems I may have over stayed my visit. But I really was only trying to help. I see now, my over zealous enthusiasm, has been drastically misunderstood. Good Luck to everyone!

Blast, now I feel like bad poster:-(

Okay, I was slightly over stating it in my description of this thread and I appreciate your intentions were originally well intentioned so an immediate apology on that particular one. My observation though, from someone who checks this thread a couple times a week, is it some times comes across as a bit evangelical in the pursuit of proving everyone suffers from the yellow peril. I guess keeping the thread alive has it's uses as it flags to potential buyers that, despite what Apple say, the issue is still prevalent and they can base their purchase on a wider gamut of information.

You're correct that this issue has not been addressed by Apple at the manufacturing stage but then people were naive to ever think a "fix" would be sorted so speedily. This seems to be an inherent engineering issue on this LG panels technology and one, which I suspect, the choice of LED backlighting is responsible for. Earliest I can see a resolution is the next refresh and even then I have my doubts it will improve - maybe if the technology has caught up we might see a revised LG panel but bottom line, Apple is committed to a multi million 5 year supply contract with LG which I can't see being broken by either party.

Nathan - I agree with you totally. A couple of weeks ago, I posted something along the same line. Average consumers could care less about the yellow tinge. They don't even know about it. A small % of folks care about every single thing and will scrutinize every nook and cranny. Nothing wrong with that. But don't you think it is time to move on. We all know the display is not perfect. No display out there IMO is perfect, whether it is on a tv, camera, monitor etc.

Apple does afford you a 14 day return policy. If the iMac does not live up to your expectations, return it. Within a year, I'm sure you can also make a case for a refund. What's the point of returning the machine 5 times or more and hoping to get a good one? Don't you have something else better to do? Is it because you can and Apple allows you to?

If the machine does not live up with your expectations, just return it. Go buy a MSI or Dell all-in-one and move on.

Over time new people will get a new iMac, notice a yellow tinge, search the web and find this thread. Then people like Dino. Jacques and others will help them figure out whether they should keep it or return it. And the thread will be a place to talk about this thing that is marring their experience with what is in other respects a fantastic product. This is the point of this discussion forum.

So suggesting that the thread just stop, when the problem isn't going away, is selfish and counter productive. There is another solution if you don't want to hear talk about yellow tinge. Don't come here. That decision is completely within your control.

I agree with Nathan that the soonest we will see an improvement is the next revision. I also agree with hamproof that many, many people will never even notice the problem. Neither of these points change the fact that there is a problem. No screen is perfect, but some screens are less perfect than others. The iMac, promoted as the "ultimate display", falls into the latter category.

The thing that makes it so frustrating is that the top half of an iMac screen is such a fantastic machine. A tantalizing teazer of the perfect home PC. This, together with the fact that Apple is the only place to get an OSX based PC, makes buying "a MSI or Dell all-in-one" a non starter. Certainly not a helpful suggestion.

We just have to wait. And in the meantime this thread is a place where people can talk about it. If you don't like that discussion, go elsewhere.

How were you able to get a replacement unit three months after your initial purchase? I thought I read here that they would only replace the entire unit for up to a month after you first buy it. Thanks.

This is to all the trollers on this thread.. Also to Dino and those which have provided probably more information than we ALL probably wanted to be aware of... sometimes it's better to be kept in the dark... LOL

This AM I took my REFURB 27 i5 into the Apple store for a same day display replacement. After waiting all day, I finally got the call. After patiently waiting 45 minutes, I was presented with my REBORN display... LOL SO..... Drum roll..... *The yellow was gone! Completely!* I ran the battery of tests we on this thread are well aware of... Yellow gone.. I was in shock. Unfortunately I discovered dust, lint and 2 dead pixels! NFW!!!! The lead apple tech there took my iMac and attempted to take the glass off to clean the dust. Unfortunately he was not able to do so, as their work environment in the *Apple Stores are NOT dust FREE!* During the course of taking the glass on and off, they scratched my iMac front bezel, and also possibly damaged the display and or glass itself. Scratches on the glass and the LCD.

As I have said in the past and I will continue to say... Apple, will do you right.. if you're not a jerk, listen to them, not be angry... and just be polite. I am not saying be a pushover by all means, but be a consumer who just wants what they paid for.

I was given a NEW, NOT refurb i5. Here's the catch! *My NEW week 9 iMac 27 has the yellow tinge.* It's there... I totally see it, but not as noticeable as the prior.

Apple's NEW Display/LCD panel replacement DO ADDRESS the issue it appears. It needs to be a panel from 1 week or newer. Not a spare sitting around for who knows how long. I can honestly say the YELLOW will go away with a screen replacement. DONT waste your time with machine replacements. You will end up just like me... in the same situation as I was before... Regardless if my serial number started with a YG and now begins with a W. The issue is there and LCD replacement is inevitable.

So do I take the plunge for another screen replacement? I will call Apple Care, register my NEW iMac. Make them aware of the yellow screen tinge... and wait. These machines are fairly new... the techs DONT have the experience yet to whip these LCD panels on and off... Personally they need time and I am personally willing to give it to them. The iMac i5 is an amazing machine... fast, bright a delight to look at. I now have all the confidence in the world that in the next several weeks to come, the yellow issue will go away.

The color is a totally different issue. The gradience is far from perfect, however, after running the bar test on the LCD panel from my REFURB... The bars looked 10X's better in comparison.

For those that are just whining about this post and taking jabs at those that have gone above and beyond to assist the others... Well go pound sand. I can betcha you haver ran the gray bar test... Uh Hello... Anyway... Individuals like you are push overs and just go with the flow... follow the wave... Personally I think you are weak... no spine and put down others to make your self conscious selves feel better... JUST MY HONEST OPINION.

Dino and those that have educated us and know where we are all coming from, big thanks!


Apple.. great customer service... but we still have words to exchange and an issue to resolve... if not now, sooner than later, that's for sure.

Wow, that is horrible! So close to victory, then failure! However, that is absolutely good news about the lack of yellow in the exchanged display! On Macrumors, a user iSee, who had also been plagued with bum iMacs, has received a flawless one! I think we are coming out the woods.

This thread has become some what irrelevant in recent weeks. I dip in and out but it's literally kept alive by the same old posters repeatedly pushing their agenda. It's also rather militant in the fact that those purporting in helping others are actually rather guilty of being blinded by the cause - jumping on anyone who doesn't subscribe to their view. It's a pain the yellow iMac but surely people have got better things to do than day after day metaphorically waving their banner, cutting and pasting peoples photos to prove a point and berating people who claim they don't have a yellow screen issue.

This thread also has a ridiculous social hierarchy, there's the obvious self proclaimed "King" and his defending minions who repeatedly claim that "we are only here to help" but heaven forbid if any other contributor steps out of line as they are soon put in their place. This thread certainly needs some new blood as nothing new has been discussed over the last month just the same old same old repeatedly being said and some rather fanciful and misjudged theories being bandied about.

For the record, I received a replacement (week 10) to my week 50 iMac (I waited three months before I initiated a replacement) and it's even more yellow so off it goes back to Apple while I consider my next move. There was a time when I regarded this thread as a useful resource but that time is long gone.

Do not apologise for rather EXCELLENT post 🙂
Personally I can not see the reason why 27" iMac owners (with problems) post here instead of calling Apple and sorting things out.
Winging about "yellow tinge" here will not fix the problem - Apple is the only one that can do that for you and it looks like they have it well under control now.
So, cheer up - the help to your problem is only a phone call away 😉
Do it now and stop wasting time posting here...

Agree, I've been in contact with Apple Executive Relations through out and the customer service is flawless which is a good job really as this particular iMac revision and it's non existent QC is far from it. It's getting kind of embarrassing for my point of contact at Apple as they're bending over backwards to sort this out at their end and being let down by the actual manufacturing side of things.

In response to an earlier post saying that a screen replacement will solve the issue - unfortunately the anecdotal evidence would disagree with you - it seems to be completely hit and miss with many reporting as bad and even worse screens as the one being replaced. Personally I think we're far from out of the woods as the issue is far more inherent in the technology used in this panel and there is no quick fix - it's going to be at least a fair few more months (probably longer) before it's addressed.

Finally, contrary to what some say on this thread there are good screens out there and not everyone is afflicted. There are also various degrees of yellow and also some users who are completely indifferent to the issue due to their uses of their iMac. If someone says they aren't affected there seems to be a prevailing attitude on this thread for them to have to prove it with photos and then for those photos to be "analysed' and then for them to be proven "incorrect" Also, for those who ask "have I got the problem?" - well if you need to ask then really it's a non issue as your own eyes should tell you all you need to know.

You forgot the long awaited White Knight who is going to save this so irrelevant thread 🙂

I meant to say earlier, my week 10 replacement was apparently "pre-screened" to ensure it was yellow free yet it's more yellow than my current iMac. I don't think my contact at Apple was lying regarding pre-screening as we have built up a pretty good relationship and it was only after an extended period of time (with my agreement) that they felt confident to re-order a replacement as Apple had introduced this particular protocol. They explained they would have to send a separate instruction to ensure that this replacement was indeed pre-screened prior to despatch. Very disappointing that, over the years, Apple have failed to ensure their QC has kept up with the increase in demand for their products.

In answer to an earlier query asking how I had managed to get a replacement after three months...I reported the issue within 14 days but, by my own choice, opted to hold off on an instant replacement as, at the time, I felt Apple had not addressed the issue. After three months and the recent Apple statement I, and my Apple contact, felt in a better position to request a replacement. Obviously my and their faith have proven mis-placed.

No point really as we're just going to continue going around in circles.

... and so it goes again and again and again....
Just stop posting guys....
... hang on, I have just posted again... 😉

Hi atlatnesiti,

I made a phone call, but they gave me no answers about the yellow tinge. They were polite and professional, but they gave me not one clear information about this issue.

I wrote two emails:

+Dear Apple Team,+

+Nov 2009 I wanted to order a new 27" iMac, but than I found this thread in Apple Discussions:+

+Topic : New iMac 27inch screen flickering/tearing/shutoff+

+I decided to wait with my order and I was very happy, when the 27-inch iMac GraphicsFirmware Update 1.0 (December 21) was released. After some days it was clear that this update didn't help everybody and there were still a lot of people reporting about the ongoing flicker issue. The release of the 27-inch iMac Display Firmware Update 1.0 (February 01) finally brought the solution.+

+February 2010 I was sure to order, but than I found a second thread:+

+Topic : Yellow tinge from bottom to top of the screen, 27" iMac+

+This issue is really strange, because some of the posters think it's not an issue, but probably an illusion. Many think that the problem is the immature IPS-technology, but what do I know. The only working fix seems to be the LCD & LCD cable replacement, but to speak clear, that would never be acceptable for me.+

+I've to admit that I'm an Apple Fanboy (24" iMac, iPhone 3GS, 4 iPods, ...) and I wanted to have a new 27" iMac i7, 2TB, 4GB under my Christmas-tree and I can tell you, my hole family can give evidence about that. I'm waiting now over three months with my order and I'm still hoping to get a perfect machine, but these spooky issues remain a big problem for me and I don't want to invest my hard earned money in a sort of lottery. I know that Apple would repair a faulty machine and that I could also have a refund in the worst case, but that's not a solution for me. I need a perfect working computer without compromises. I promised my 24" iMac to my son and he's also very disappointed about this situation.+

+Please tell me honestly, if it's safe to order now. If you're not sure, so please give me an indication when the yellowing will be fixed.+

+Thank you very much for your efforts+
+... still dreaming of an 27" iMac i7+

+I'm still waiting for an answer. My email was not a joke!+

+Please visit this Topic: http://discussions.apple.com/thread.jspa?threadID=2218213&tstart=0+

+You can also call me, if you prefer to do that: ...+
+I'm speaking German, Italian and English.+

+Thank you!+


*I'm still waiting for an answer, but no answer is an answer, too.

Yea atlatnesiti, Apple is the only one that can solve the yellow tinge, but please don't try to convince us that the help to our problems is only a phone call away. Nice idea! :)*

I totally agree with you in this article
