Had some time to sit down with my replacement iMac and I can honestly say this week 10 model, which was supposedly pre-screened prior to despatch, is more yellow than my week 50 that it's replacing. Lucky I got it as an advanced replacement as this ones going straight back to Apple. I don't consider myself to be hyper critical or have unreasonable expectations but a screen which is over 1/3 yellow is definitely not acceptable.
As for Apple getting on top of this screen issue......all I'm saying is "my ar$e".

seeking some advice
This is my second 27" iMac, I had some noticable yellowing on the first one... this one is a bit harder to tell.. but I think it has way more backlight bleed than the last one.
Should I be considering an exchange or just getting a refund till these issues have been finally fixed? Normally for a cheap sub 200 monitor I dont care that much, but this thing was 1800 after taxes, I feel like I should be getting something a bit more consistent.
What do you guys think? Thanks in advance!
First set is at 50% brightness second set is at 100%

It looks fine to me. For the back-light bleeding, it seems nothing if compared to mine. I got it every corner of the screen and all are bigger than yours. I posted my screen pictures in few pages back. Page 63 I guess
Anyway, It's a keeper to me.
If we're supposed to believe the photo of the backlight bleed at the bottom of the picture is accurate, then what are we to make of the glaring white band at the top with its apparently glowing edges?
We know there is really no such glowing or halo around the top bar, so why would anyone think anything other than that the image is not accurate enough to draw conclusions from regarding light intensity?

Okay.
I can take these again, but this is pretty accurate to what I see with my own eyes. What annoys me is that the left side leaking is much more yellow than the rest of it.
your screen is yellow towards the bottom right.
You'll be using the machine for at least 3 years and if you don't want to look at that everyday then return it.Hi everyone,
I just realized I do have the yellowing on the right side of my screen a few days ago. And I'm very disappointed.Do you think the yellowing is enough to get it replaced ?
yes, I think that is the case unfortunately. Maybe, just *maybe* they should learn from Toyota and apologise and recall sooner rather than later?
spending that kind of cash for such a crappy screen doesn't make you happy. so rather send it back and maybe hold out for an update... I just sent mine back last week and it'll take some time before the replacement arrives. Mine had horizontal grey bands and the yellow tint...
I'll probably play cat-and-mouse with Apple too... just keep sending it back... and if the replacements still have faulty screens and rumours of new iMacs are coming out, just get a refund.
Apple Australia has said they'd refund or replace my iMac if it happens to the replacement machine... I really don't want a refund because I need to use the computer, so hopefully the screen ok.
You know those refurbs probably came from the defective iMac stockpile? With the new ones hardly getting any defect-free screens, do you think they'll replace the refurbs' screens?just got my i5 refurb today, I see the yellow tinge on the bottom of the screen
Same here in Oz. Replacing a machine would take a week as it needs to be sent back first...
Have the power supply replaced. Your screen is okay... (apart from the light bleed).
Week 10, I think its yellow
I bought an iMac today hoping for the best. Salespeople were pretty evasive about the issue when I asked casually about it.
I think its yellow, I notice it most when I'm dragging a white window around the screen.
Here are the pics. I'll be trying to bring it back for a refund tomorrow.

Can someone please check mine again, I've retaken the photos, here they are 100%/50%/0% brightness in the 3 pictures attached. This is a week 10 iMac 27" i7 which was made in Shanghai. Purchased through Apple online store guy told me all problems had been fixed. Anyway this is day 3 of using this iMac, and as I use more I find more problems, and here they are, are people experiencing these and are they considered to be a problem, consider how much I spend on this I am now looking at getting replacement as I find more problems.
1.Yellow Tinge mainly strongest on the bottom right corner looks like an L shape yellow tinge.
2.Pitch noise when brightness is not on 100%, but you cant really hear it sitting about 1m away from the iMac because some other voice is covering it.
3.Its either noisy fan or noisy hard disk, first 2 days was ok now the hard disk tends to click alot more then before. Also either hard disk fan or what so ever is noisy louder then pitch noise so I cant hear that pitch noise at all. The 21.5" iMac I got prior was alot more near silence then this machine.
4.On the 1st day my iMac was running all night, it was suppose to auto sleep with default energy saving options but, I can still hear the fan going but the screen is black. I try to wake it up with my mouse but it didnt work. If I manually sleep it I can easily wake up, seem to have problem with waking up from a long night sleep(just once so far)
5.Even without turning on the iMac, just the power pluged to a power pluge, I can hear a buzzing noise coming out from the back on my iMac is this normal?
Here are the 5 problems I've experienced so far, I may be picky but if Im spending 3500NZD on a machine Im expecting it to be perfect. Should I ask for replacement or keep this? Either way Im definitely going for an iMac so either keep or replace any suggestions?
By the way all 3 pictures are taken at night where the room lights are all turned off, taken with Sony WX1 if that helps you guys decide upon the pictures.
Thanks in advance

Well, my first Mac (and it hasn't taken away my excitement mind you as I am very much a Windows user by default - but it took me all of about 1 hr to be impressed by the Mac) and I have the yellow tinge. Now typing this on my 2nd iMac 21.5" which also has the tinge.
I'm in Australia and the retailer I bought mine from is JB Hi-Fi who have been VERY helpful and have gone out of their way to help me. They've even gone as far as set up a few iMacs for me to pick one to replace this replacement with to make sure I was happy. But I could do nothing to stop the astonishment on their faces when I showed that all 3 iMacs plus the 27 incher they had on display all had the yellow tinge problem.
So I've agreed to keep this one until they can get a new shipment in. Hopefully the new ones from Apple won't have the problem (anyone have any hope for me?)!

There's some yellow on yours, but it doesn't look too bad judging from your pictures (i've seen worse). But it's hard to say, it's also personal, how much does it bother you when you're working with the iMac?
I'm currently comparing iMac 2 and iMac 3, they're both week 10 and both screens look very different, unfortunately none of them are uniform and neutral. I'll post some pics later.
The high pitched noise is there, I can hear it too (both iMacs here have the faint, high pitched whistle). But as you say, it's hardly audible. It doesn't bother me personally, I only hear it when it's absolutely quiet in the room which doesn't happen very often.
The fan and hard drive are two different things. The fans should only start blowing when your machine is doing very CPU intensive tasks for quite some time and definitely not during sleep. You'll know it when they're operational since they're pretty loud (like spinning discs). The HD sound (don't know how to describe this) is not anything to be worried about, that's just part of the machine.
Both iMacs here don't produce any sound when turned off.
I think in general there are currently no perfect, uniform, neutral screens available. If you try a replacement now you might end up with another iMac which has similar or other issues. But I totally agree you should get a good machine for your money (that's why I had mine replaced, twice). It's a difficult choice. I also remember over the years none of my Macs were flawless, they all had 'something'.
My 3rd iMac was delivered on friday as a replacement for iMac no 2. Since I have them both here, I took some photos side by side. Both are week 10 models made in China. Both @ 50% brightness, same color profile. Photos are unedited except crop/resize.
The displays have a very different feel. Left iMac (nr 2) clearly has yellow on the right side from top to bottom, iMac nr 3 (right) has a yellow tint overall.
Perhaps in looking for a solution Apple has increased the yellowness of the screen to prevent the spots from standing out? But even iMac 3 (right) seems to have an increased yellow area on the left of the middle.
I'm currently undecided on which one to keep, or returning them both.

yep, yours is yellow... if you would prefer a replacement i suggest they set up their macs and let you pick the one that doesn't have yellowing since the ones that are defective would end up being returned by customers.
yours looks alright but except towards the very bottom, judging from the photos. it looks fine until the bottom edge of the grey block as the yellowing looks intense...
Mate, are you in Brissie? I doubt they'll do that at my closest JB HiFi. I really do appreciate they actually acknowledged the yellowing on all of their stock machines...
I got mine off the online store via virgin blue's velocity rewards site just to earn some mileage... but I guess it'd be better to buy at a physical store this time. I'm waiting for my replacement -- dunno why but Apple AU/NZ needs those defective computers back before sending out the replacement... it'll take about a week...
wow. so this is what the firmware update did, just trying to cover up the problem... you should change the colour temperature to match the left screen and see if you notice the yellowing more clearly. My wild guess is that it would, and you should just return both and wait for a newer replacement.
No mate, Rockhampton. Yeah can't say a bad thing about them - have the best service out of ANY electronics shop I've been to.
The guys at JB are telling me they have a new shipment coming but Apple won't tell them when (which is usually the go with Apple so I'm told by others) - so they are guessing in the next 1 to 2 weeks.
Any word on the newer iMacs? Does it still exist in the fresh stock since Apple have now acknowledged the problem?
Apple is aware, but won't acknowledge officially. When will they learn this is an exact repeat of Toyota's recalls (except this time Steve Jobs won't be grilled with questions).deemer76 said:
I can imagine all the returned computers because 99% of people who have problems with yellow screens have returned them, and will keep on returning them. Read a few pages of this thread. The other 1% either doesn't realise or is too late to return and tells everyone else to live with it since they can't do anything about it.
Peed on screen hey, remember that Simpsons mapple episode?
If you read one of the recent replies, Apple is aware of this issue and has released firmware updates. They warm up the screen's colour temperature to disguise this problem. There's an elephant in the room, hello?
My first iMac was a week 9 and it had the yellow tint towards the bottom, PLUS 2 horizontal grey bands (like a poor quality photocopied document). I'll be receiving my replacement sometimes this week sent from Shanghai via Sydney.
While a yellow screen is totally expected, I think it'll be a newer batch. I ordered mine as soon as the delivery time on the site dropped to 24 hours (week before last).
I was in the Apple store yesterday and they put a new screen in my 21.5" (this is the 4th ive had now) and it still had noticeable yellowing in the corner and bottom. I was in the store for 2 hours and 1 hour the evening before before they gave in and took the machine back for a refund.
I WILL NEVER BUY APPLE AGAIN.

My machine is quite weird, I just checked when the iMac is sleeping you wont hear any buzzing or pitch noise from the back. However when the iMac is turned OFF you will hear a buzzing pitch noise from the back. I tend to think my yellow pitch looks like a L shape on the bottom right corner.
I think I might go for a replacement but it sucks here they taken in the replacment one then gimme the new one feels so stupid without machine
well done, a sensible person.
you should have asked them for something for the inconvenience.
I'm definitely eating crow. I was one of the iMac 27" owners who said they did not have any display problems.
Then after a few weeks I thought I saw something - reading text at the bottom of the screen looked different than at the top. Then last week it became very apparent that the bottom and especially the bottom right was clearly yellow tinted. The grey bar test definitively demonstrated it.
I got a refund. They did not refund the sales tax. Is that typical?
I can't leave OS X and don't want to build a hackintosh. I think I'll get an 'entry level' Mac Pro and hope that the 24" LED cinema display does not have these problems. Now just waiting for an update to the Mac Pro.
This iMac model appears to be a real lemon - literally, yellow color and all.

Successfully returned! The manager originally wouldn't confirm over the phone that they would process my refund, but after very minimal pushback from me, they agreed to the refund over the phone without even seeing the machine.
The salespeople told me to check back in a few weeks and that the floor models didn't seem to have problems so there is a good chance I'll get a good one next time. I checked the floor models and they both had slight yellow tinge, though with the bright mac store lights it is pretty hard to tell.
I am just going to sit it out until this is all resolved.
Jeez... I've been doing more reading around the net, this is a really huge problem isn't it? Surely Apple must be losing money over this?
Let me know how you go with your replacement mate. If the replacements come in here and still have the tinge, I think I'll be switching to a MacBook for the time being until these issues are resolved.
I got my week 09 i5 last week and am very happy with it. No yellow, no noise and no dead pixles. Some small amount of led bleed but to be expected and only noticable when the screen is totally black.
