Just called Apple about the yellow tint issue I have with my imac i5 and was offered to return it to MacConnection or get it repaired. I asked about on-site repair and the lady told me if i have AppleCare then they can have someone on-site. :(

I really don't want to return it to MacConnection, it took me 45days to get it.

arrrrrrrrrrg!!

Sir Cecil, whilst you may have a small point regarding the photos, why not do people the courtesy they afforded you when you had issues with your first two iMacs? Your comments are just inflammatory, crass, vulgar and TBH you come over as a prize class d*c$head.

This kind of argument is ridiculous and I don't know why people use it anymore. It takes a mere thirty seconds out of one's day to type a post on an Internet forum, and assuming that a member spends "hours" antagonizing people is baseless and pointless to assume.

I think both sides are acting a bit immature about this whole thing. This is a forum to discuss Macs, not delve into petty personal insults and other inanity. Go up to the local high school if you want worthless drama and teenage insults, but if everyone could leave it off of this forum, it might make it a bit more fun to read, not to mention considerably less aggravating for lurkers like myself who actually like to hear thoughts about the iMac over squabbling such as this.

tl,dr: Keep it on topic and stop being a bunch of little kids.

For the time it takes to make 1-2 posts, he could've taken a picture. That's just some excuse. The poor guy has low self-esteem. It's so obvious.
 
Hi everyone! Long time lurker, first time poster.

Got my 27" i5 iMac yesterday. Week 52 model with some yellow originating from the bottom-right corner and 8(!) dead pixels in the iSight camera.

Called Apple support today and they're going to send me a replacement. Replacement's ETA: February 2. Apparently two weeks of shipping time is currently a common occurrence. I'm still hoping they'll be able to fix the problem in the meantime.

I'm from the Netherlands (europe) btw, so I hope it doesn't have any implications shipping-wise. It probably has, but I guess I'll just wait and see.

P.S.: don't feed the troll. :)
 
Which Hardware is at Fault Exactly?

Hi. It's a good thing I haven't bought the iMac yet. From all the tests and things that's presented itself. It doesn't seem to be the GPU, glass, software, driver, firmware or CPU. But it seems to be a hardware problem. Which exactly is that hardware?

Is it the LED used? As we know white LED which has that disadvantage of tending to become bluish or maybe yellowish instead of white. Is it because the current is weak on the side of the LED that it becomes yellow much like an old incandescent bulb when it's not in it's prime anymore then that means there's something wrong with the circuit, maybe there are capacitors or resistors that are not up to spec?

Electronic engineers who are members here, do shed up your hypothesis please:) Let's help Apple fix this.

Happy new year and merry Christmas. Thanks in advance.

Gbu,
Alvin

Yesterday, I went to BestBuy and wanted to buy 27" iMac but it's sold out. It's not available in stock. But the co worker told me that there will be a new model of iMac. He suggests that it may be a little more bigger. Probably, 32". Do you know? So I guess I will have to wait for the new model.

I was in a BB today and so I had to check out the iMacs. The 27 " one had a good screen It was a week 41. I overheard an employee tell a customer an iMac could not take more than 4GB of RAM. The sales people don't seem to be very well informed.

What I noticed in the very good reviews of Dell's Ultrasharp U2711 (which is rumored that they are using the same LM270WQ1 panel as the 27" imac) is that they are using CCFL as backlight.

I'm getting to believe the guy who have made the remark in the past that the cheaper or low quality white LEDS have something to do with it.
 
Mine has the yellow tint issue, just slightly at the bottom, which is ok I think, not going into critical work(for the moment).

What worries me more is that all of a sudden (at least I started noticing it after getting a lighter wallpaper) cloudy (condense?) marks have appeared on my left top.

I had a first matte Intel 20" Imac that had the same problem, but that was after 3 years, so I had to live with it.

I've seen a clean screen in BB as well. The guy said it was very old or from the very early batch.

Can't take more than 4G's? Sounds like they dont/didnt have the 4G+ machines in stock and tried to steer. Unethical. I hope you corrected him.
 
21.5 iMac purchased on Black Friday. Serial Number starts off with W8947.

Definitely noticeable when Gmail or TextEdit are open.

Sorry if this has been recovered already, but 42 pages is really too much to go through for me.

What I want to know is, does the yellowing really worsens over time? Is this common with yellowing? If not, what is this claim based on?

All info is appreciated!

I've had my iMac for almost four weeks now and its slight yellowing hasn't changed. I think what might happen is that some folks don't notice the yellowing at first but when they do finally notice it they assume it must've suddenly appeared or gotten worse.
 
I have had my i7 since mid-November. The yellow gradient has not changed since the first time I turned it on.

Difficult to tell, I have my i5 for 6 weeks now and I was under the impression that it is a bit worse now then 6 weeks age. But I also feel it hasn't grown the past few weeks. So this is very subjective :).

I also feel the yellow tinge is a bit more after I have used the computer for some time. When I switch it full off for a night or so, the yellow tinge is less after I started up again.
 
My replacement just prepared for shipment

I was hoping the delay rumors were true but mine is prepared for shipment so I guess I'll still be a member of the yellow club.

What makes you think they didnt fix the problem? I dont think it would take the manufactures that long to fix the problem weather it be the hardrive or screen. To me it would only take a couple of days to get it right, because they know what the problem is, all they have to do is correct the problem. But i guess we'll see, or maybe they were backorder on parts and thats what the delay was all about:(
 
I Purchased a brand new 3 ghz dual core imac 27" two weeks ago and have noticed a yellowish tinge at the bottom centre of the display "only" after reading this thread today. For me personally it's not a critical issue as I primarily use the imac as a multimedia solution with the screen around 8 feet from the viewing position.

However, I've cast my vote for the record

@poobear,

That comment was added when there were about 20 or so different people reporting that the effect had worsen, whether it was within a few hours, a day, or a week. Some even have swore that it did. If I were to count again now, there would have been at least over 50 different reports that claim the effect does indeed worsen. Some of these reports cite that they had made sure they could not see the yellow while doing the same test, and then later on they could see it clearly.

Here's an example from one of the more recent posts:

PaoloS said:
I'm almost sure the yellow wasn't there since day 1.

After a first repair (high freq noise), having been alerted by this discussion topic, I went through the whole set of tests in http://imac.squeaked.com/ but found nothing, even if I was, so to say, looking for defects.

Unfortunately, less than a month later, I cannot avoid seeing the pale yellow (similar to nicotine patina) in the lower/lower-right part of my screen, even without running ad hoc tests.
It is sufficient to look at this very web page with Safari in a maximized windows to notice the difference between the higher-left and the lower-right part of the screen.

My suggestion is to keep an eye on it, while at the same time trying not to become paranoid
If you're not sure the yellow's there, it probably isn't: should your screen begin yellowing, you'll have no doubts about it.

For some pictures of yellow tinged screens, you might want to have a look at https://forums.macrumors.com/threads/824940/

Good luck, Paolo

Of course whether this is really the case, or whether if it has to do with environmental factors (such as temperature, surrounding light sources, the colors displayed on the screen itself, etc) we could never really know for sure. Even if that is indeed the case for a particular display it would still be very difficult to deny so many reports.

While not entirely related, there were people that had a similar problem with the previous generation, 24" Aluminum iMac, also stated that their screens have gotten dramatically worse over year(s).

I am also aware of screens with the color temperature tinge remaining exactly the same in the span of over a month or two. In the end I would encourage you to read through the threads (and especially the threads over at Apple's support discussions) and then make your own personal judgement on this one.

I have updated the original post to reflect that the conclusion that I have came to previously isn't a very concrete one. I apologize that it was worded in such a way.
