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

[TennisandMusic]

Well, I have a feeling the uniformity issues will never be resolved. I've been doing a little monitor research, and found something.

Someone in this thread (See Thread) mentioned they had tried THREE of the 24 inch LED cinema displays...and never got one with uniform color. That means

A) This problem has existed for some time
B) Apple has known about it all the time
C) Since it is still present in Apple products, they really must not care.

Let's think about this...if the LED monitors from June had this issue, Apple has had months and months to sort out the issues on those products. One would easily assume these QC measures would apply to the nearly identical iMac monitors. Instead, problems are just as prevalent on these products and it is now nearly 2010. This can only mean that Apple will probably NEVER fix the QC issues on this machine, or that the tech in the monitors prevent them from ever being 100%.

Now the problem is, if I want desktop power but refuse to buy the currently way overpriced Mac Pro...then what the heck Apple?

The problem with this logic is that they are actively marketing the iMac's "beautiful display" with its "perfect picture with superb color consistancy".

If they knew this not to be the case, then that makes them liers.

False advertising is illegal.

How is that a problem in "logic" when the results point to exactly those conclusions? Do you have any other explanation?

Someone else mentioned in here the inherent problems in white led backlighting, vs rgb led backlighting. He claimed this could NEVER be fixed. Now look at the results we are seeing, and look at what people in that other thread from half a year ago are saying, in regards to both the cinema display and the use of white led backlighting.

I don't really think my logic is the thing that is faulty here...

Yet there are people with the 24" ACD without the yellow tinge. Either way this is not looking good. Apple is likely going to fix this in silence sometime in the future, if at all.

I have included some photos (of yellow tinge on a 27") by Big iMac in the main thread.

Hmm...are there? How many, and can we see posted pictures? We have yet to see any posted pictures of a perfect iMac, and frankly I don't think many people bought the 24" lcd anyway. And if the few who are complaining, then what? If Apple had sorted uniformity issues on their LED ACD's, why would we be seeing the same issues now, half a year later on the iMac when it's the exact same tech?

Just for the record, I have an i5 I bought Tuesday (week 48). and I don't really have a yellow tinge, but I DO have a blue tinge on the right side of the monitor. It is not uniform at all, and now I fear the iMac's will always have this issue. Exchanging seems to be futile.

But now the issue is...how do I get a decent OSX desktop? If these iMac's do not work as advertised Apple literally has zero reasonable choices. I'm really starting to think Apple cares nothing about it's customers...

This is not an LED LCD panel issue. I also own the 24" LED LCD for the powerbook, no problems at all.
It's a screen manufacturing problem. There are perfect working displays out there but they are the first models.

There's at least one more mention of the 24" LED not having this issue in the same thread.


Anyway I feel the same way as you do about Apple's desktops. I will not settle parking the 27" quad core and use another display as the main screen.

I'd suggest that perhaps they care MORE about their shareholders.

Well if it were a manufacturing issue, I would wonder why Apple would not have sorted it out by now. Also, I see many references to white LED's being inferior to rgb LED's but if this is solely a color issue, I see no problem with the iMac's color. It looks incredible. If only it were freakin' uniform...

I would strongly consider a Dell 30" monitor, and a Mac Pro, but not only is this much more costly, I have no idea when the new Mac Pro's will be out (or how much they will be!)

I will probably just return every two weeks until I get a working and uniform machine. Hope I don't get too annoying.

Didn't someone in this or another recent thread here post that he was told they would not take any more of his machines back after his second one, and his third then arrived with a cracked screen? (They took it back anyway - hard to argue with an obvious exterior physical problem resulting from poor packaging.)

This scared me off ordering another 27 - if Apple is getting ornery with people and starting to refuse returns, then you don't want to order one of these while these defective units are still shipping. By the time they fix it, if they do, there'll probably be new Pro and/or MBP units.

Dunno, I've read stories of guys doing 6-7 exchanges so...who knows. If they tell me that I would just ask for a refund and do something else. No way they can stick you, legally (right?), with a machine that was bad. I'm pretty nice in situations like this, so usually the people are willing to help. But we will see...

Also, my "superdrive" in this one is going painfully slow. Trying to copy over a DVD and the stated time is TWO HOURS. I put the disc into my laptop, and it correctly stated 10 minutes. It's actually going to be faster for me to do that and then do a network transfer. No idea what that is about, but that is pitiful...

Well, this is the reason why I try not to buy rev. A hardware, or at least I try to wait a bit before ordering, to see if any major problems are reported. Ultimately you are taking a chance in any scenario - problems can develop in later revisions, or don't appear until a few months into usage.

But this time I don't have a choice - I need a desktop badly. As it is, I'm pushing it, and postponing ordering the i7 to January 14. I'm hoping that by then, they'll have most of the obvious problems licked. I'm especially wary of the flickering screen issue, and also this yellowing problem.

Perhaps expecting them to diagnose the problems, engineer a solution and re-work their manufacturing/assembly process all by January 14 is a bit optimistic, but I really can't hold off longer than that - especially that I'll be ordering from re-sellers which means 2 extra weeks of waiting for the shipping, potentially putting me into February before I have the i7 in my hands.

Anyhow, one slightly optimistic trend, it seems that the newer built quads - weeks 49-50 have fewer problems. I hope that trend is real and not an illusion. It means they are making progress. We'll see in the coming weeks if there are as many complaints with later builds. Anyone else have a sense that the most recent builds seem to have fewer problems, or should I put down the crack pipe?

Pass it along! A lot of earlier buyers didn't see problems until a week or two in - too early to know if the people who have just gotten them are any different, IMHO, and in the absence of clarification from Apple, you'll never know if/when they fix anything or what it was.

Oh boy. Well, there's only one thing to do: wait for reports to flood in. Perhaps in the next two weeks or so. Mostly we need the numbers to ramp up - it's silly to draw conclusions from just a few computers, and there's not enough of the 49&50 weekers to have a decent sample. But by January...

Those screens look really disturbing.

I'm no professional but I would've noticed it right away, and it would annoy the hell out of me.

Yellow...

It's been forever since I've posted here, and was hoping for my first post back to be a good one. Unfortunately, I took delivery of a 21.5 iMac two days ago and it indeed has the yellow tint at the bottom. It is subtle, but as some here put it so succinctly, you can't "un-see" it once you know it is there. I actually noticed it without the test pattern posted here, but I used it to confirm the issue. It doesn't seem as bad as some of the others I've seen posted, but it is aggravating.

Note that mine is a refurb; one of the early 21.5 iMacs to hit the site. Basically I gambled and lost. I knew about the potential issues, but I figured Apple would do a better job testing that they did. Be forewarned; this particular problem apparently can skip right through the refurb process. I have no idea why it was returned in the first place, but the rest of it seems fine.

Not sure what to do at this point. It would seem that the odds of getting another bad one are pretty high; it might even be worse. My other concern is that although I have an Apple Store close to my home, the fact that it's a refurb would likely mean I have to wait for them to ship me another refurb. I don't know that for sure, but I could understand Apple not wanting to hand be a brand new iMac for $200 off. I don't like the idea of being down a computer for what could be a couple of weeks, but I already transitioned my old G5 to the kids. I've never had a bad Mac before, and I've had my share of them over the years. In fact, I don't ever think I've had any bad computers. Bummer; maybe I was due


Oh well; just another data point I suppose. I'll have to figure it out over the next couple of days. If there are still those out there that still thinks these problems are isolated, I suggest they put down the bong and do a little more digging. I was surprised to see just how many people have had the problem, and how prolific the post were on sites other than this one. Even the Apple Support site has some pretty drawn out threads on it.

Good luck to all!

Trust me, I saw it at the first gray power up screen the first time I used it.

Anyone complain to apple about having a yellow tinge on their QC 27 inch imac more than once?

From all the posts on this forum, I'm guessing it could take even 3 or 4 machines to get one without a yellow tinge.

I know, right! That's why I've been hesitating so much to take it back for a replacement. That and the fact that I'll have to go at least two weeks again without a decent desktop computer...

That's why I'm waiting till January to return it. Hopefully they'll have the issue straightened out by then, and there's no point in rushing back when Apple extended the return period to Jan 7th for all purchases made after Nov 1.

Week 47, 27" Core 2 Duo.

Very slight yellow tinge in bottom third that I only noticed after seeing this thread. Most evident in bottom left area.

I spent a good deal of time reading this entire thread and one other and I have some question about how to approach replacement for this issue.

1) My iMac was purchased from MacConnection. I also purchased the AppleCare plan from Amazon. If I wish to get a replacement, should I call MacConnection to start up the process or directly call Apple?
2) When I send back my iMac and get a new one, will I be sending it back to MacConnection and receiving a new one from them or will Apple take over since this is a technical issue?
3) I already cut the UPC code on the shipping box to mail a rebate. Does that affect the right to replace the iMac?
4) I see this "14 day" period mentioned several times, that you can get a replacement within that window. Does that apply if you bought it from a reseller like MacConnection and where is this mentioned? I skimmed my Applecare leaflet and see no mention of this.

Thanks for any info.

Why don't you call MacConnection and ask them? You'd get the "real" answer right away instead of a guess from an anonymous forum member if/when someone even decides to respond.

FWIW, the 14-day return period mentioned throughout this thread is for items purchased directly from Apple.

Good lord, Google is your friend. It took me literally 30 seconds to find this information. Besides, that only applies to items purchased directly from Apple.

Cause they're closed on weekends and I'd like to figure this out this weekend if possible.

If you're just returning it, you'll still have to pay the 10% re-stocking fee.
