I have ran all updates and firmware within apple update with no luck :apple:

Going to call Apple for a replacement!

[DoFoT9]

yeh unfortunately these things happen. take it straight back if you arent happy with it. ask for a different production week.

[Gregintosh]

I'm kind of confused. Are you saying this Mac was manufactured one month in the future in July of 2010?

My calendar says it's June 2010 right now. Maybe I've just been watching too much Doctor Who.

[aliensporebomb]

Sssh! Dr. Who is in this thread!

So I just got one of these and all I can say is when I booted it my jaw dropped in awe over how great the screen is.

BUT....how do I know if I have the "yellow tint issue" or not? My own Acer 23" screen has a more yellow tint than this thing. Ideas?

[newhere]

Just finished talking with apple support.


I have paid full price via apple web site for my first apple computer, they asked me for a refund FIRST or a replacement, I mention to then that I have paid full price and expected a fully trouble free imac, and that i could get a new imac from a reseller much cheaper, they wouldn't refund anything!

So, I requested a full refund, I will get a new imac via apple reseller and save about $300 dollars or more 

cheerssssssssssssssss :p

Be careful going to a reseller. Apple is very easy on returns. Not sure all resellers are.

now i am confused. you think going to a third party reseller will get you a better machine? sure it is cheaper($300+ cheaper???)

What makes you think it will be any better? Same people make them ya know ;)

Sounds more like you were a dick and they would rather give you your money back vrs dealing with more of you attitude.

How did u get them to do this I'll be returning my second one in a couple weeks and I actually asked if I could keep it until the update. They said the best they could do is give me 30 days to switch it out or get a refund

More reason not to buy an iMac until they have updated it to the newer revision.

Never be a Revision A owner. Just like iphone 4 with the antenna problem which will absolutely be fixed in iphone 5.


Remember A stands for "All the trouble with a new design"

And B stands for "Better design with all the lessons learned from last revision"

To the OP:

ALL of the iMacs have yellow tint to some degree. It's inherent in the design. Please take a look at the iMac patent for the LED backlit system and you'll see that Apple even states the lack or diminished color uniformity found within this new technology. That a dispersement of color will be evident. The process Apple has engineered to implement it has created these yellow-like blotches.

Apple is placating their customers with replacements, however, some of the replacements have actually been former returns, evidenced by the scuffing and other indentifying clues.

If you've been following the board, no one has really recevied a perfect iMac, devoid of any color inconsistences. They ALL SETTLE. Please understandthat before yopu put yourself throguh a long frustrating cycle of return/replace/repair - all to no avail. Often, they have MORE problems. not less.

You need to either accept this fact or look elsewhere. The yellow tint problem is not going away. In fact, I now belive that the Rev. B (soon to be out in the Fall) will also contain this same flaw. It is just the technology, for now.

Best of luck in deciding what to do.

May I possibly suggest, that like the iPhone 4. The issue may be inherent in the "design" rather than the technology. And Apple won't change the "design" as it costs too much to do.

I don't really accept that all screens that use led backlighting have to suffer slight yellowing towards the bottom of the screen.

I can however accept that due to a less than perfect design (led layout/diffuser) that this may occur.

[newhere]

I was very polite on the phone with the support people and the cancellation department, they called me if I would like a replacement and get a $150 discount and a free printer.

POLITE IS THE KEY :D

[newhere]

I just receive my second imac 27, this is worse that the first one, on the top left corner, on the middle and on the right hand side all along.

This is my first switch to mac, i am so disappointed, should i ask for a refund and wait for the new imac or just ask for a replacement again....another two weeks waiting :mad:

[Piggie]

And this my friends is why you should never (unless it's a portable/mobile device) put a computer and a screen in the same box.

Perhaps one day Apple will see sense?

An ideal solution (that would probably keep everyone happy, give users more choice and save Apple a hell of a lot of money in returns) would be to have the iMac look roughly the same as it does now, but have the computer un-clip and come away from the back of the screen (be means of a connector bar)

So, (in theory) you could have the Mac in a plain grey rectangular box that connected onto the back of the monitor screen to make it into one unit.

If either part failed, then either part could be replaced.

If done right, even giving the possibility of unclipping your iMac box from the back of your 24" screen and clipping it onto the back of a 27" screen.

Thats a decent idea, but aesthetically speaking, apple would never go for a rectangular box mounted to the back of the monitor. Apples all about the unibody design and streamlined form factor, even if it does rack up more substantial costs when something goes wrong.

I'm as anal as the next guy.

I used to be a graphic designer for chrissakes but quit that racket when I realized I could make a lot more money doing the I.T. thing.

My 27" screen is about as perfect as I could want. No yellow blotches.

I've seen pictures of the blotches online but it kinda sucks that so many of you
are experiencing this to some degree.

I'm sure mine might have some somewhere but if it's there I don't notice it.

[aki]

Yeah I got a 27" a few weeks ago and my screen is fine, or at least fine enough that I don't notice.

[Twols]

I have the same issue with my 2 week old iMac i7. A kind of yellowish tint at the bottom of the screen. Looked today at some macs in the apple reseller store, they have the same "issues". The bottom is warmer, especially if you open a light grey image.

Should I let apple fix it? Or is this color difference "normal" for 27 inch iMacs? For 2k it can not be "normal"...

For the one billionth time, there is no fix. (not directed at you,; just in general)

This is inherent in the design. You either live with a little yellow or go elsewhere.

Please look at the iMac patent for the LED backlit screen. Apple states that these color inconsistences are normal.

Reading between the lines on that link.

It does sound like what they are saying is:

As we try and cram a computer into the same case as a screen (unlike almost anyone else) then the monitor will get extra hot in places, and due to this we will get colour variations on a LED backlit display.

If the display was separate from the computer then this would not happen.

Am I reading this wrong?

[Btom]

......

Some people claim "perfect" screens. The root cause of the yellow tint (and to some degree other colors) was not made public, but it has likely something to do with the used light dispersing method.

On the bright side there is a number of large screen LED TVs on the market completely free of the problem, so lets hope that Apple buys one and learn, how this is done.

Don't Apple make separate monitors that use the exact same screens as fitted in the iMacs?

I know everyone else will disagree, but I do wish Apple would make an iMac but have the computer in a small/smart aluminium/glass box separate to the monitor.

And no, I don't mean a mini mac or mac pro.

It is not the same panel (24"). I don't recall any tint complains on those, though...

What you think of is a "Mac Pro Light". It would be nice, but eventually it would be very similar to Mac Mini, I think they don't want to compete with themselves and eat their own Mac Pro and Mac Mini sales. Just MHO.

Are all these returns sold off as refurbs, or once back at factories might they be turned around (with same screens) as new units?

They are obviously good enough to be passed by quality control as new units.

I have the same problem, disappointing... I actually sent mines in for repair, because of yellow tint and deadpixels. Got a replacement (brand new imac), on June 21th 2010, and guess what it also has yellow tint, even worse then before.. I have it on the bottom right side..

I've got the 21.5" iMac.. Why do iMacs suffer with this issue? I've bought a lot of monitors in the past when I was using a PC and I have to say I've never encountered a yellow tint issue...

It can only be down to two things if you think about it:

1: Heat (due to a computer squashed right up against the back of the screen and hotter in some areas than others)

2: Due to their being a computer squashed right up against the back of the screen the backlighting LED layout needed to be arranged in such a way as the make everything fit in.

There is no other reason why LED's if they were distributed evenly across the back of a LCD panel would be any different in one area of the screen than any other.

The fact that this yellow/discolouration seems to be always in the same areas of the screen tells us it's some design or heat issue that must be due to getting everything to fit in the one box.

Unless all the Apple stand alone LED backlit monitors also suffered from the same discolouration in the same areas.

Still, some people claim (CLAIM!!) they have a "perfect" screen.
I suggested some time ago that yellow tinters should not be replaced, but returned for cash. The next step should be purchase of a new one (exercise only for the willing, i.e. eternal optimists). This could break the vicious circle of "my third replacement is worse than the first computer I got". Just could.
I really hope Apple will shape up and solve the problem. Unless they are currently focused on an iPhone G13, or something....

It's pretty normal, Apple is not the only one doing it. It's pretty hard for us to get evidence that could actually hold against Apple in court of law plus what would we get? Maybe some money but that wouldn't stop Apple from doing it. Under the fancy appearance of Apple, there is this not-so-nice side. It's just one company among others, all trying to do as much profit as possible

Still, some people claim (CLAIM!!) they have a "perfect" screen.


I was one of the first people to own the 27" i7 and I ended up getting one replacement for a yellow screen and then I returned the second one for a refund....At the time I thought the problem was widespread on every iMac even though there were claims of "perfect screens"

Some of these recent perfect screen claims were from professional photographers so maybe things are getting better?

The percentages of people complaining about yellow screens is so small compared to overall users that either were super sensitive to it, we all have horrible luck to get so many bad replacements OR the "perfect screens" out there really aint so perfect.

Because I really would love to have a 27" quad core and thinking that Apple by now has solved the problem (or at lease has made it better), I just bought another 27" i7.

Wish me luck!

There's something to be said for being "told a problem" and being hyper sensitive to discovering it on your own.I have not a clue what to look for in the screen yellowing and missing pixels.My i7 looks great and I expect it to stay that way.

I think that people are looking for things. Not saying that yellow screens don't exist, as I had one full replacement and then a screen only replacement. However, in retrospect, i think that I read a little too much of this forum and began looking for inconsistencies that may or may not have been there.

I think that Apple did a great job in handling this, as any television manufacturer would have told you to take a hike after the first replacement. The LCD technology is varied, and if you can't deal with that, then either go CRT or Plasma.

I had to return two because they were just unacceptable.

A imac can cost more that $3.400 hardware! People have the right to demand perfection from a premium priced item in a world where Apple is several years behind in the latest tech hardware and overprices for it.

My screen wasn't yellow but it was making the high frequency loud "dog whistle" sound that was almost deafening. I returned it today to the Apple Store for a full refund.

Color consistency on any modern LCD TV screen (including LED) is very good, otherwise they simply wouldn't sell. Just drop by to your friendly BestBuy and have a look for yourself. No problems with availability of anti reflection coating of the screen either.

I think that once you 'think' that you see something, you continue to see it no matter if the screen is perfect or not. Stare at a stuffed animal long enough, and it will move...lol. Its a shame as those people won't ever be able to enjoy their purchase.

That a dispersement of color will be evident. The process Apple has engineered to implement it has created these yellow-like blotches.

Apple is placating their customers with replacements, however, some of the replacements have actually been former returns, evidenced by the scuffing and other indentifying clues.

If you've been following the board, no one has really recevied a perfect iMac, devoid of any color inconsistences. They ALL SETTLE. Please understandthat before yopu put yourself throguh a long frustrating cycle of return/replace/repair - all to no avail. Often, they have MORE problems. not less.

You need to either accept this fact or look elsewhere. The yellow tint problem is not going away. In fact, I now belive that the Rev. B (soon to be out in the Fall) will also contain this same flaw. It is just the technology, for now.

Best of luck in deciding what to do.

Granted, there is a bit of a discrepancy between marketing and reality, but the Apple iMac page specifically says this (http://www.apple.com/imac/design.html) about IPS displays:


IPS technology.
The iMac display is designed to look great from almost any angle. A technology called in-plane switching (IPS) makes this possible. Whether you’re sitting in front of the display or standing off to the side, you’ll get a perfect picture with superb color consistency and no loss of detail.

I suppose one could argue that "superb color consistency" doesn't equal "perfect color consistency." One could also argue that many of the displays sent to customers (including myself. Three times.) don't come anywhere close to being described as "superb."

I expect better from Apple.

I think the golden standard we should use is an average large screen LCD TV set (also using IPS technology). Without all the "Superb", or "Perfect" hype, they simply display uniform white, or shades of grey. Period.

Not making excuses for Apple here but you really cant notice the tinge unless your looking at an all white screen or the screen test.......(or Macrumors) .

My bad i7's ALL had yellow tinge but when I had an image opened in lightroom or PS I couldn't see any difference in colors to my other LCD IPS monitor.

I doubt that 90% of the users wouldn't even have noticed there screen if it had not been for that screen test. I have seen so many posts from people that didn't even notice until they took that screen test.....

I agree, that the yellow tinge is not a show stopper for most. Hey, I'd even say that 90% of the people don't really realize the laptop they use everyday have a TN type display and wouldn't tell it from an IPS, unless pointed to specific features and allowed to directly compare.

On the other hand I still would like to know why my computer screen may be missing 5% - 15% of blue at the bottom, or could have a 10% lower brightness band along the bottom edge of the screen, or 15% lower brightness in the corners. My LCD TV clearly doesn't have these.

My 52" Samsung has developed clouding in one corner. You can't tell it at all when the LCD is on, and its really a beautiful picture. However, after the set has warmed up, and if you are looking at a black screen in a very dark room, you can slightly see it. I called Samsung and they told me that unless it reached a certain degree of issue, they don't replace them. 'Degree of issue' is certainly subjective, and can be determined by Samsung at will. Will I buy another Samsung...oh yeah. In my opinion, they have some of the best looking LCD's on the market, and blow away the competition IMO.

Point is, that with the LCD technology of today, its not perfect, and maybe it will never be. As a consumer you can either continue your never ending quest to find the perfect LCD, or accept that and move on to something else that you are happy with. I'd refuse to keep exchanging out my LCD panel every time there is a small issue. What a pain and inconvenience. I'd rather go buy something else that I'd be happy with. If every manufacturer replaced an LCD panel because of the slightest discrepancy defined by the end user (me), either prices would shoot up for the overall end user, or you'd see that company go out of business, and they won't let that happen.

I'm not saying to settle if you without a doubt have an issue, but to be so sensitive that nothing will appease, that's not a reasonable.

I just read in the other thread that some guy was raising the gamma rates in Photoshop so that he could identify where the yellowing was on his screen. Good grief.....now we're getting into OCD land.
