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

[macgasi]

a suggestion for easing the yellow tinge..

Hey guys I've read this forum up and down before receiving my 21.5 inch imac and mine indeed does have a slight yellow tinge at the bottom third of the screen. But I'm not sure that it's something I would have noticed if I didn't know about it. and from everyone else's experience, it seems like getting an exchange doesn't guarantee that problem will be solved..

so I fiddled with the display colors, and it's currently on Generic RGB Profile - which in my opinion made the tinge less noticeable.

I don't know, if you don't want to deal with exchanges/convincing apple associates that there is a problem, and if the tinge is slight but acceptable.. maybe it's better to find ways to ignore it.

Just my two cents.

iMac #4 arrived this morning. It is a week 11. Yellow tinge along the bottom right of the screen.

5 months wasted on defective computers. I'm getting a refund and going for a Mac Pro.

 

[iSamurai]

Man my compensation is the crappiest though 50NZD, if this one they send me is still ****, Ill ask for another replacment and a better compensation. The apple care guy try to persuade me buy apple care so a technican can come and look at my machine. I should tell them give me free Apple Care if you so want to come and look at it also + 50NZD atleast lol. I think with these problems Im definitely gonna buy apple care when i settle down with one of these imacs before the first year warranty runs out.

Don't ever buy Apple Care or any extended warranties! Just recently on BBC Click they interviewed this guy and he said it's almost 100% profit for companies. It's not even worth the paper and packaging that came with it and almost all hardware/electronics don't fail throughout their lifespan. If the computer is defective on arrival it's clearly not your fault and it is irrational to buy Apple Care.

Does the compensation vary proportionally from the top of the world to down under? lol

Tell them you have been a loyal Apple customer for several years and have put a lot of time and money into the new iMac. I said to them "None of the iMacs a acceptable. Are you forcing me to buy a PC? What can you do to keep me within the Apple community?".

lol. I love this. I will definitely use it in my next call as everything you wrote there is in fact true and relevant to me They're coming to pick my 2nd iMac back tomorrow (I'm using it now) so hopefully the 3rd one is problem free.

Apologies for the low quality pic, just taken with my iPhone. What do you think, am I imagining things?

It does look yellow towards the bottom, but I can't 100% say that. Maybe try with a proper camera.

Hi Guys,

I´m extremely disappointed with apple, i buy my computer in december, it had several problems among with the yellow tinge.
After 3 repairs, apple gave me another computer (week 11), when I connected it, I felt so angry, the yellow tinge is even worse then before, now it is on the center, the left corner and the right corner.
Why don´t they fix it, why they aren´t honest with their customers.
I have a 46 inch led lcd tv from samsung and it doesn´t have a single yellow tinge in all corners, so how it´s possible that some brands can produce lcds without colour variations and lg don´t ?

First iMac 27'' replacement

Hi guys,
I've just received my first iMac 27 replacement.
The first one had yellow tint on the first 1/3 lower part of the display.
This one is better as far as yellow is concerned but it has a grey band in the bottom part of the screen from left to right.
What do you think about it ?
Please have a look at it:

It obviously has a yellow tinge left of the centre, and mostly at the bottom.
It looks quite "good" compared to the earlier ones (of the late 2009 models).
But still inferior to the colour uniformity Apple used to offer.

iMac #4 arrived this morning. It is a week 11. Yellow tinge along the bottom right of the screen.

5 months wasted on defective computers. I'm getting a refund and going for a Mac Pro.

Good idea. Ive ordered the 2.93GHz quad core. I know its twice the price as the iMacs after i buy 2 screens. But it'll last longer. The resale value is much higher than iMacs. I'll choose my own screens. And its upgradeable.

I've been looking at 2 22" HP screens for £300 for the pair.

Hi Brothers and Sisters!

I have a Sin - I bought an iMac.

The story you all are familiar with.

About a month ago we went to a local store and were told that Refurbished Macs are available for a cheaper price and will have all benefits new machines have....and they were right, it was cheaper and had what new Macs had - yellow tinge.

So, a week later first machine arrived. I picked it up from FedEx and brought it home. There was several stuck pixels and the yellow tinge. I grabbed the box and rushed to a local store where I was asked to contact Apple customer support, since this unit was purchased online. I spend 1.5 hour on the phone explaining my problem and was told that there were LCD anomalies, which were normal for this kind of displays. The store was closing and I had to call Customer Support the next day and spent another hour before they agreed to replace my iMac.

So we packed everything, and I brought it to UPS.

In a few days new machine arrived (picked up 12 kg box from FedEx) and it had yellow spots on the bottom of the screen. I phoned Apple again and they agreed to replaced it once again. We packed it and shipped through UPS.

Few days later the 3rd machine arrived - was picked up from FedEx and again, the display had the same problem as the previous one.

I phoned Apple again, spend another hour on the phone and a customer relation agent was assigned to me with known phone extension, etc.

She suggested me to go with a LCD panel replacement. I was concerned that new machine with replaced screen sounded suspicious, but was assured that since it was my third computer, refund would be provided if there were problems. OK! We ordered the part and in a few days my local store representative called and asked to bring iMac for a repair.

Few days later they called and asked me to pick it up. That's what I did, and guess what??? The tinge is still there - now its covering 1/5 of the screen on the left. OK! I phoned Apple Agent, who has been working with me and she asked me to send a picture. One hour later she called me and told that she spoke with engineers and they said that this yellow tinge is within the specs and the known issues with yellow screens are about the whole screen being yellow, not a part of it. WHAT!? Supervisor on the phone. He is saying the same thing, that technical department looked at my pictures and are positive that this is within specs and he maybe, may be able to schedule me for another screen replacement. I said: I want a refund, I want my money back - he says: I can't give you that. - Why? - Because it's been repaired already. - But, I specifically asked if that could be a problem in a future, if I would want a refund. - Well, I don't know much about it, what I can do is look at your situation and call you back this afternoon or evening...

That was 6 hours ago. (3PM EST)

P.S.

On the website, all iMacs presented do not have any yellow spot. It doesn't say anywhere that products may be different from what you see. Product should comply with a certificate issued under their company act and I really don't think, that it says that yellow pee-spots may present.

Here are my corners. Hit me if I'm wrong.

 

[Sir Cecil]

Here are my corners. Hit me if I'm wrong.

Such a montage of corners is meaningless, of course. We have no idea if the screen, covered in reflective glass, was evenly lit from the outside, let alone the inside. What was opposite the glass when you took the picture? A 100% flat background without even a hint of variation in tone?
It's hard to believe that anyone producing such meaningless pictures purporting to be accurate evidence would be offended by yellow tint in the first place.

Take a picture with your camera of a flat wall painted in any single flat matte or gloss color and if you chop it up and show the corners of the wall cropped together, you'll get four different tones. Then you'd probably say the paint manufacturer was to blame.

TNT has come to pick my 2nd iMac up today. Back to my trusty old MacBook. Hopefully I can bring some good news to this thread on Thursday/Friday. Fingers crossed.

My screen suffers the EXACT SAME issues, even down to the amount of yellowing, gray banding and extra.

I have the slight gray banding in the exact same place, only a small amount of yellowing at the very bottom of the screen, and even that semi-circular gray area in middle right edge where backlighting isn't coming through as strong.

I mean overall it's a very great screen, and you don't notice the defects at all unless looking really close, but still not perfect. The alikeness of our problems and many other gray banding problems I've seen with the same semi-circle gray area on right edge tells me there's something very wrong with how apple is implementing the new batch of backlighting, as they're all very similar in their defects.

This scares me. I just received my 1st iMac back after having the LCD panel replaced and it's different to how it was before. Not necessarily worse, definitely not better but different.. it now has a greeny / smoky haze down the left 1/5, yellow across the bottom edge and up the middle and the grey bar across the bottom.

So pissed.

Monty Python

Hi there, while waiting for the return of iMac after repair nr.3 with panel nr.6, another thought on compensation:

Those that received a compensation: respect!
Those that received a minor compensation and being disappointed about it: cheer up!

It reminds me of Monty Python's Life of Brian, in the dungeon: "...oh, they even spit in my face!" - "...oh they like you! They never spit in _my_ face in 25 years and let me hung dry the wrong way around for half of the time!" (not cited exactly as I'm not a native English speaker, but you get the picture)

I'm in Germany, have bought additional Apple Care and...

... am not entitled to on site service
... was graciously allowed for pick-up service only after bringing the iMac to repair twice
... each repair was longer or about 2 weeks and I did not get another PC for the time
... since I did not buy at Apple directly, I was not offered a new machine or a refund
... guess what, the shop I originally bought it would not take it back since it was repaired somewhere else (they would have sent it in too...)

I received no and none compensation for all that.

This experience and some other things I disliked with Mac & Mac OSX (I'm a switcher) plus the Mac Mini being nearly the same price as an entry level iMac and still being the cheapest alternative will influence my next computer buying. Right now I just don't see where I get the advantage over using Windows other than having a computer in a more or less well crafted housing.

 

[mjsmke]

They're just about to update the Mac Pro's aren't they?

Theres been rumours around for a while but no solid date. Plus the new ones will be more expensive. And the current Mac pro has had great reviews. After the iMac screen experience we know Apple don't properly test new technology, and im not keen on testing new technology for Apple.

 

[constm]

Here are my corners. Hit me if I'm wrong.

I had very similar experience (4 replaced iMacs, plus screen replacement). Ended up having refund. Insist on refund because you specifically asked if it's possible after repair and you ahev been told "yes".

I feel your pain, prostranstvo.

Good luck.

Dude, are you getting payed by Apple? The only reasone i've posted only corners is to show the radical difference, but here you are. Picture was taken last morning:

I've been using macs for almost 7 years and my very first PBook screen is still better. Why? I dont get it, sorry.

 

[iSamurai]

You should read his post history (as mentioned by another user) on this thread. Since he got an acceptable iMac replacement, his attitude towards other forum readers having the same problems has changed.

Don't get me wrong or implying anything otherwise, but just sayin', not hatin'.

 

[lexvo]

Yes, that's yellow tinge and quite a lot too (provided you didn't saturate the image).

BTW: don't pay attention to Sir Cecil

Whoah...

This HAS to be one of the worst iMac screens posted on here yet.

If I were you, I'd immediately get a full refund. No way would I want to have a screen likethat for the next 3-4 years.

Is this problem EVER going to be solved by Apple?

SirCecil has had the same problems too. He's even asked for photos himself of other screens, so you shouldn't feel bad.

My iMac screen has an unnatural tinge.The bottom third of the screen is lovely and warm, almost sunny and definitely pleasing to the eye, but the top two-thirds seems to lack yellow content and looks cold and uninviting.
Should I take this back?

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.

I have a slight yellowing at the bottom of the screen myself. So I am all for accurate tests that show the problem and help resolve it. It's a pity a respected publication hasn't produced such tests and images in a professional environment.

What I'd like to see is a color, photographed with his camera, at his location, with his setup, and shown to be color-accurate across the frame. Not a portion of the camera frame, but the whole frame. Simple request I would have thought

To the original poster:

Take a photo, with your excellent camera, of any large sheet of card (in any light-toned color of your choice) and post it here for our perusal. I'd like to see an un-retouched photo that exhibits absolute tonal consistency right across the frame, that can be examined with appropriate tools. Please add something in the photo to indicate the scale of the photographed image (perhaps a pen or coin).
Shouldn't be difficult for you to do – after all, you've done it once already with total accuracy, haven't you?
Let's see it.

After several exchanges without quibble, Apple has offered to fix it. If they can't fix it yet because there is no fix, then he has the choice to keep it until there is a fix, in which case the obvious-to-all flaw will be clearly discernible and repaired under warranty, or he can now (presumably) get a refund instead, if he's within the refund period.
What is the problem with that? It sounds to me as if the customer holds all the aces.
I have had frustrating problems with Apple hard drives, Macbook Pros and other items, but I have ALWAYS received respectful service and solutions. I have NEVER felt pressured into accepting something I did not like. Never.
I have complained here even in recent weeks about hard drive noise and have even stated that there is now some minor yellowing at the very bottom of my screen. Yet I feel in no way under pressure to accept these things and get only positive response from Apple when telling them the problems. When I told them the yellowing was very slight but that I had concerns it might worsen over time , they told me they would send another and if one was better than the other, to choose the one I preferred and send back the other one, or return both for full refund.
What could be more reasonable than that?
Of course, if I behaved like a fourteen-year-old brat and told them I was out to bankrupt them and drag their name through the muck on a forum, they might have been less obliging.

I received my replacement i7 2T (Week 53) this morning. Thanks to the fact that Apple allowed me to keep the previous (Week 50) unit until after the new one arrived, I have been able to check them side-by-side for the last 4+ hours.

I considered the previous unit fine in all respects apart from a narrow line of yellowing right along the base of the screen. It faded into clean white at around the height of the dock, and above that area I could detect no yellowing at all. No flickers were experienced. I reported the yellowing to Apple, not to exchange the unit, but to make sure my observation was registered in a case history for any future eventuality. However, the last of the three personnel I spoke to that day suggested a replacement in any case, keeping the one I had in the meantime. A no-lose offer, so I accepted.

I have seen the yellow tinge problem so I don't deny its presence on some screens. But there is not one photo in this entire thread that is an even remotely accurate representation of the yellow tinge problem.

On a scale of 1 - 10, how would you rate this yellowing?

I purchased a 27" iMac 2 weeks ago, and recieved one with distinguishable yellowing. I received my replacement today, and still see yellowing, but it is less obvious.

The center of the screen appears much brighter than the edges of the screen (the 'blocked' colors shown below are from the same shade-of-grey bars).

To those who have seen both the yellow and non-yellowed screens on the 27" iMac, how would you rate this one on a scale of 1-10 (10=perfect, 1=worst yellow screen seen yet).

5 images:
1: full picture
2: image with key
3: top and bottom bars together
4: light grey bar extremities
5. dark grey bar extremities

I spoke with the Supervisor again, and he said that he was not aware of a promise to refund money if i dont like the replacement, so he had no other option, but to make me happy. So, i'll get a refund once I ship it back to Apple.

Thanks to all of you.
