IMac :: Help! IMac 21.5" (Late 2009) Showing Slight Yellowish Tint!
Jul 24, 2010
Hey guys! So just a few days ago, I received my iMac, and boy do I love it. A definite upgrade and improvement from my old Acer Aspire 3680.
But despite this, I have noticed that my iMac does have a slight yellowish tint at the bottom to corners. I just arrived at my desk, and the login window (I keep a password lock) had a slight yellowish tint when I woke up my iMac from sleep . I then noticed that the bottom two corners had a slight yellow tint to them. I verified this via the MacRumors Forum post, and I was able to find it out by making my desktop background white. Again, it may not seem noticeable at first, but if you examine it closely, it becomes apparent.
I've already called my local Apple store and one of them said that don't know about this issue (?) and that they could schedule an appointment for me. I declined because I have to have me parents take me and I'm pretty sure that I can't handle the load of carrying a 20lbs. computer w/o dropping it (yikes!).
So here's the big question, should I go to my local Apple store or call the Apple hotline when it's open (currently closed at the time of this thread)? I don't want to sound like a lunatic or someone that just wants to get a better iMac for free. Again, it's slight, but considering that I do movie editing and Photoshop work

So I got a brand new iMac 5 days ago and I connected my dell 24" (2407) to it.. I seem to have a yellowish tint.. I tried to calibrate it and it still seems to have it on there... On my pc the dell has a perfect screen.. Yesterday I go to turn on my new iMac and it wouldn't turn on.. I kept on pressing the power button and it wouldn't turn on.. So I unplugged the power cable and put it back in and nope didn't work... so at this point i am upset i pressed it really hard and it turned on.. So i turned it off and pressed the button again and it seems like it is working again, but why would it do that in the 1st place??

It seems that the xBench results for the new 21.5 iMac (base model) are about the same - and maybe a tad bit lower - than my late 2006 20" 2.16 Ghz iMac (score: 140.8) My Geekbench score is lower - c.2900 - it seems, but not by as much as I thought.
Can this be? Is my machine just as fast as the new base models? I've always found that my 2.16 was a bit pokey, sometimes take 15 secs to launch Entourage or Word and 5-10 secs to launch Safari. Opening documents takes a while as well. I was thinking of upgrading, but these speeds are not encouraging.

early 2009 Intel iMac 24". OS 10.6.8.Â
Working in Excel today, I was highlighting groups of cells with color when the entire screen suddenly had a pale grey-green tint. Can still see colors beneath, but everything tinted (not just the Excel window, but the entire display). White, of course, is most dramatic. The Dell monitor beside it is fine.Â
I've recalibrated color a half dozen times (have always had to do that to get the Dell and iMac screens as similar as possible). It's impossible to get white on the Mac. Rebooted several times, including hard boot, zapped the PRam, ran Permissions Repair and Disk Repair from the startup CD. Installed Temperature Monitor to see if there's a heat problem, but I could not find normal temp values anywhere on the Web, so that was something of a bust. Temps attached below in case there's an educated set of eyes out there....Â
Ran some online tests, too, for color distortion, dead pixels, that kind of thing, but nothing reveled.Â
I've been all over the Web looking for some guidelines, but most posts at apple and elsewhere seem to focus on later-model iMacs with the yellow lower screen problem when new (It's not that) or panic screens of wild colors, stripes, and the like. This is just a grey-green tint that covers the entire screen, rendering whites grey-green and colors muddy.

So, for some reason when I have a secondary display connected to my Mac Pro, it will sometimes randomly get a yellow tint. Turning it on and off again will fix the problem, but then it'll only be a matter of time until it randomly gets a yellow tint again, usually when the display gets focus.

I have a mid '09 macbook pro unibody and just managed to spill a coke on the keyboard. I immediately grabbed the closest thing, a throw, and mopped up the coke before grabbing a tshirt and trying to blot the rest. As of the first 5 minutes of the spill, no problems. What should I do? The left control, option, and command key's backlight now has a yellowish tint, I assume from coke.

i just bought the imac 21.5 inch with ati radeon 4670 and the base spec. after few hours of playing with this new toy. i realise that when you press the shutdown button, it will put the imac to sleep instead of showing the shutdown/restart option that i have on my macbook. Is there any way to make it work like a macbook power button. secondly, whenever my imac wake up after sleeping, the fan will run faster and automatically went to sleep again. this issue just keep repeating itself. i have no choice but to shutdown the imac and boot up again. Thirdly, i try the machine on WoW and i realise that the sound is rather choppy

I've been playing StarCraft II the past couple of days and noticed the fan for the first time since I've gotten my iMac (which was in November). So I touched the top of the screen and it was burning hot. Is this normal? I really haven't heard the fan until playing SCII, so I'm not sure if my iMac has always been hot.

Since I use my machine a lot for photo work, this new feature on the refresh was nice. Question is does anyone know if it's easy to swap the card reader out of the 2009's for the new SDHC reader?

So I have a 2009 iMac.Earlier this year, I upgraded to Lion. A little while after this upgrade I started running in to an issue that is now making my computer unusable. When working on graphic or labor intensive activities I am receiving Red Green and Blue pixels around my screen (see picture below) Shortly after this happens, my screen freezes and becomes unresponsive with these pixels still up OR it will completely glitch out, blinking and causing the whole screen to go crazy. Things I have tried so far, rebooting my system from scratch, replacing video card (not cheap )

I'm not sure what the culprit is because the night I downloaded the last update of 10.5.8, the circuit for this room also blew. I don't know if it interrupted the download or not, as I wasn't paying attention. However, the next morning I woke up to the gray screen and it never booted. I finally was able to boot it up and the hard drive had a name like kjkldfjkjdkljafkjadkj. I renamed the hard drive and ran disk utilities on it. It needed to be repaired, so I installed the installation CD and used disk utilities from it. It says everything is fine. However, the hard drive now does not show up under Devices when using Finder. Also, everything seems to be a lot more sluggish now.

Alu 24" 2.4ghz when they first came out with aluminum, got it at the store. since august 07 My imac had a small yellow tint, i noticed, when i got it and it was not worth anyhting screaming about, i also noticed it had bleeding issues ath the bottom and sides. I wanted to return it or trade but i was convinced out of it.
Now i noticed that from left to right their is a prominent yellow tint streaking it's way across and fading around the half way point.It is irritating and sad to see this display on this mac was ok, at first but it is geting slightly worse.I have apple care, can i trade this/replace it at an applestore, or would they need to fix it?

i went to clean some smudges on my screen today and noticed that there are some spots on the other side of the screen's glass... this there for anyone else? It's pretty freaking annoying. This machine should be perfect.

Now this is my first ever Mac after being dragged into the Apple world by my iPhone and iPad. I love it, everything is a joy to use and i've been surprised at how quickly I have adapted to the world of Mac.
Anyway when I got it home on the day I noticed a spec of dust under the glass. Called Best Buy but surprise, surprise they had sold out of the model I had. No biggie I thought, I will get it looked at one day.

So I took the hefty plunge and purchased the 27" i5 from a local Apple Retail Store, believing that Apple would have finally resolved the yellow-tint issue from over a year ago, or at least it would appear in much less iMacs as it has sorta died down on the forums.
Anyways, opened it last night, and continued copying over files to it today, only to notice that it has a slight yellow-tint issue towards the bottom 1/3 of display.
I've already made a genius bar appointment......I even purchased Apple Care on it, so the total was around 2.5k, and I'm hoping for them to allow a swap for another brand new unit? Is this likely, or will they just simply wave me off to a repair or refurb route. After dumping so much $ on it, and even purchasing Apple Care, I wouldn't be satisfied for anything but a straight exchange to a new unit.
Also, will they allow me to open it up right there and check to see that it doesn't have any display issues as well?

I have read the many many threads on the Yellow Tint issue although i am concerned about buying a 27" i5 Imac as i've been saving for a while. I'd be really disappointed if i end up with a screeen with the yellow tint issue.
What i would like advice on is the following:-
Has the reason behind the yellow tint issue been found and has it been resolved?
Would waiting for the next updated Imacs be a better option as i am not in a major hurry to buy my imac although i would prefer to buy it sooner rather than later considering the time i have been saving.

On my white iMac (Late 2006, 20" C2D 2.16ghz) I've almost filled the puny standard 250MB HD and am planning to have an authorized repair shop replace the drive. (They quoted me $30 plus the cost of the drive -- is that a good price?)Question: what drive should I put in there? I'm planning to go with a 1TB/7200 RPM drive, but can I or should I go bigger? Faster? Which brands to use, or to avoid?

I think it worked at one point, but sometime around the point when I set up Fusion with the partition, Windows Aero turned off and is no longer an option in the display settings. I installed this driver with the modded INF to see if it would do anything, but Aero is still not an option. I also have issues playing some games in Fusion, while they work fine in Boot Camp.

Specifically the hard drive fan runs at 1600rpm and the optical fan always runs at 1350 rpms.
Those fans run faster than my 2007 24" 2.4ghz iMac.
Somehow I figured with the cooler running ddr3, 9400M igpu and better cpu architecture that this new 2009 20" iMac would be dead silent because the fans would barely have to run. Or at least be less noisey.
But that's not the case.
Anyone have any fan speeds to report on new iMacs? Particularly the 20" model?

I have a 27" iMac purchased last January. Every time the computer wakes up, the display activates with normal coloring but after a second "shifts" into a different color profile with a blue'ish tint.
All software updates have been applied. I've reformatted the computer twice since the initial purchase. Problem persists.
I'm well aware of the yellow tinge problem with 27' iMacs, but based on my research of past posts the blue color shift has only been a problem with Macbooks.

I hate to complain but this just sucks. After dealing with multiple repairs with my 24" iMac, I got a 27" as a replacement. I always keep my iMac just a bit over half brightness. I have the same problem again! why the same issue is occurring and what should I tell apple if they can't fix it!

I just got an IMac G3 running OS X and OS 9.2.2. I am having monitor problems with it, the monitor has a slight red color on the right side and if there is a light colored box on the screen I get almost a run effect going to the right. This happens in OS X Tiger with all the updates, OS 9.2.2. I also have all the firmware updates, an external monitor looks great.

When the computer is sleeping or if I turn it off but the plug remains in the electrical socket, when I get very close to the machine I hear a slight crackling noise, as if the internal adaptor is making a slight noise. I don't hear it from any normal distance, and other than the buzzing phenomenon when brightness is below 50%, no other symptom. Is this normal for this model. I believe that the external adaptor for the 30" ACD made a louder but similar noise as well unless unpluged.

I have a 15'' iMac G4 with 800 MHZ processor and 768 mb ram. I woke it from sleep one day when suddenly everything had a violent pink tint to it. I had no idea what to do. I've replugged-in the video cable, messed with Colorsync, blew dust from the internal monitor port. I don't know what to do!!

I see all these complaints about i7 iMacs, does the yellow tint affect Core2Duo models? Is the tint an effect of a MB/CPU issue or a display problem?
