How common is this? I prefer darker backgrounds and this may be an issue.I'm over the yellow and the buzzing, but this too? Don't take me the wrong way - I love my Macs but I can't say I'm crazy about this..See attachment. Ignore the image noise, the big spot that bothers me is on the top to the right.
View 8 RepliesI have not seen any posts comparing these two symptoms together, but I am wonding if both exist on the same screens, or if they are infact seperate issues. I returned a 27" iMac i7 because it had both slight yellowing and terrible backlight bleeding. I have seen multiple machines first hand (3 Core 2 Duos week 41s) at different stores (Apple and Best Buy) that had no yellowing and no backlight bleeding. I won't get into how to check for yellowing, you can read about that issue here: [URL]
But to check for backlight bleeding is both easy and impossible not to see if you have it. To check for backlight bleeding, a quick way is to bring up a site like http://www.blackle.com/ or any other black background, and check for an inconsistent white glow on the edges of your screen. I had serious backlight bleeding in the lower corners of my screen, which happens to be where the yellowing was happening. I don't know if they are related, but hopefully we can determine if there is any correlation here.
I did order a second machine, because I know Apple knows how to make a 27" iMac with a perfect screen (as advertised), since I have seen 3 of them in the wild. Hopefully they will be back to the quality that they had is their early production units very soon.
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?
So I got my 24" Cinema Display 2 weeks ago and just noticed this backlight bleeding on the bottom right and its really pissing me off when I watch movies or use frontrow.Does anyone know the best way to go about with an exchange or something?
View 9 Replies View RelatedI've had my new 13" MBP for about a month now and I am noticing what looks like backlight bleeding spots at the bottom of my screen. It is most noticeable on the bottom left and appear blue-ish on a black screen at maximum brightness. It is getting irritating when I am watching movies at night. I have the 9CBD screen. Others have said they have no problems with this screen model. So is this normal or is it a defect? If it is a defect, what can I do to fix this? My 14 day grace period is over, so I'm assuming an easy exchange at the Apple Store is out of the question?
View 6 Replies View RelatedI've got an 27" i7 which has got a significan amount of light bleedthrough from the LED backlight in the upper right side of the screen, about 5 inches from the far right. I don't have access to the display currently, but will take a photo when I get home.
It's not an annoyance when the screen is displaying bright colours, but when the screen is supposed to be black, the amount of bleed is quite visible (this is bleed down into the screen, not through the joins/seams of the unit).
Very much similar to the examples shown in this thread:
[URL]
Specifically like [URL] except for being on the top right side of the display.
Does anyone else have these issues? I realise that it is impossible to get it perfect, but this could turn into an annoyance for me, and just want to know if anyone else has a similar issue.
I also dont' want to run against Murphy if I have to send it back, as the one I have isn't suffering from anything else...
I have recently bought a new i7 27" imac and when the imac goes to slep it seems to crackle/buzz very very faintly.
I phoned apple who told me to do the following:
Turn off the imac.
Hold down ALT, CMD, and R, and then hold the power button.
Then still holding ALT, CMD, and R press the P key.
I've owned my iMac for a little over a year and I started having a weird buzzing noise coming from a hard drive fan. Downloaded iStat, everything runs at idle speeds (hard drive fan at 1200rpm), so the speed is not an issue. Sounds like a mechanical problem. Also downloaded FanControl, and once I increase the fan's speed to 2500rpm, the buzzing noise goes away, but now I can hear the fan It kind of defeats the purpose of having the expensive computer, that used to be virtually silent. I am in remote location in Alaska, where we don't have Apple store and the only way to fix is to ship it to mainland. Apple warranty is over, but I still get additional 1 year of coverage from Amex credit card, but I would much rather prefer to to fix it myself. Any suggestions on possibly replacing the fan myself? I am really debating whether I should ship it to Apple and trying to go through American Express with warranty. That would be complicated and I would end up without a computer for a few weeks.
Late 2008 iMac 24'. 3.06 GHz, 2GB RAM, 500GB Hard Drive, NVidia GeForce 8800GS.
I sent an email to Steve Jobs about my yellow tint 21.5 iMac issues (three exchanges, all affected, resulting in a refund). I got a call from Dena at Executive Care within 24 hours.
She said they are aware of the problem and do not know how widespread it is. According to Dena, the issue is not resolved and that ordering a new iMac will not result in a fixed display.
She said the engineers are working on it now and they are not sure if it's hardware (most likely) or software related. Further Apple stores cannot do repairs because they haven't determined what the issue is.
I bought a second hand iMac G3 off eBay for a pretty good deal, and am trying to figure out where the buzzing is coming from.
It doesn't come with any CDs so I don't think I can do a hard wear test, but I've noticed it is happening even when the display is off, and is in sleep (although it gets less audible in sleep).
Another thing I noticed is that in OS X it will stop after a while of not using it, despite the screen being on and still showing the image, is this the hard drive stopping? When I go and touch a key or move the mouse it starts again.
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'm curious what your experience has been with getting a new replacement either from Apple directly or the reseller. I bought mine from MacMall a few weeks ago and it seems to have a bit of the yellowing as well as 20 or so dead/stuck pixels in the isight camera and now I'm thinking about trying for a replacement. I spoke to an Apple rep earlier today and he is working to see what he can do for me but apparently Apple sales weren't wanting to allow me to just swap for a new one through the normal channel everyone who buys their iMac directly from the Apple Store gets. The rep is going to call me back on Monday and let me know what he can do for me. MacMall will allow me to return and rebuy supposedly
View 1 Replies View RelatedI 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.
Just received my new imac today and everything is perfect, quiet drive, no stuck pixels excellent apart from some bad backlight bleeding which can be seen on black screens. It's particularly bad at the top and the sides.... Does anybody else have this and should I risk sending it back??? I have a 52 inch lcd sony and that doesn't suffer at all from back light bleeding...
View 20 Replies View RelatedI have a 1.83 GHz Intel Core 2 Duo iMac that has developed a vertical yellow line in the display that won't go away even when restarted. It's like a 1 pixel column of dead pixels right in the middle of the screen. I think it's still under warranty. Is this something that can be fixed under the warranty?

View 3 Replies View RelatedI just received my new imac 27, i7 (28-06-2010). I ran the screen test, unfortunately my screen has yellow tint issue. I have ran all updates and firmware within apple update with no luck. Going to call Apple for a replacement!
View 24 Replies View RelatedWhile me and my friends were trying to figure out possible causes of this issue on LED screens, someone came up with the brilliant idea that the problem could be caused by the sound speakers. His recently LED TV had the same problem. He found out that what was causing the yellowish tinge on his TV were the Sound Speakers. Volume speakers use magnets, so the magnetic field was screwing up the colors on his tv tending to yellow.
After having removed the Sound Speakers the yellow tinge disappeared in about 2/3 hours. I tried this on my led screen laptop with a magnet I had in the kitched, and guess what! It worked, color changed, not for yellow but it changed for sure. The Sound Speakers on new IMacs are near yellow tinge, that's why some people are getting it worse. I've reported to apple. Faulty design Quality Control. If you have his tell us if you're using internal or external speakers. This may lead us to more clues.
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?
View 24 Replies View RelatedI have a week 50, i7, 2TB Imac. It has a very distinct yellow "tinge", and the Bluetooth does not work properly. Every time I reboot or start, the "Bluetooth setup assistant" starts, which I have to force quit. The wireless keyboard and mouse work fine, but I can't add either of my two bluetooth headsets. They pair, but when I try to activate them, it goes to the bluetooth settings screen, where it says that bluetooth is "off", despite the on checkbox being checked and the keyboard and mouse working. I called support and they had me do a bunch of things, the last thing being reinstalling the OS. Didn't work. So now I need to call them back. I have two problems, the yellow screen and the Bluetooth. Should I ask for a replacement? I see that a lot of people have gotten a replacement just for the yellow screen problem. I have two faults.

View 7 Replies View Relatedi bought the 2009 refurbed 27"er and returned it 3 times due to yellow screen problem. for the 4th replacement they decided to send me the new model.
i have the 3rd and 4th replacements sitting here side by side.the 3rd replacement, which has a yellow corner is light years better than the new one.
the new screen doesn't have yellow corners...it's a perfectly consistent yellowish brown tone.
the older one has a yellow corner, but is much more illuminated and very balanced white. the max brightness of the new one is only 3/4s of the max of the old one.i tried configuring it to no avail.
are all the new models like this?it's quite a bit snappier, but the screen is worse than the last 3 that had yellow patches? it almost seems like it was a return and it shipped from cali rather than asia?
I have a 24 inch imac and i am connecting the viewsonic VG921m (19'') monitor using the mini-dvi port.

So I contacted Apple this morning regarding the LCD Backlight Bleed on my iMac (24", early 2008, 2.8 ghz) They made me reset the PRAM, which I figured wouldn't work, and the issue is still there.
They say it'll have to go in for servicing, and I live nowhere near an Apple Store, so they gave me the location of the nearest London Drugs. Am I going to get the same quality of service as I would from an Apple Store? And what is the exact process that they use, do they just replace it with a new LCD?Also, he said that it will be covered under Applecare unless it is ruled as accidental damage, he said that much of the time, the issue is caused by pressure on the back of the case, and that if that was the case, it wouldn't be covered.I can't really see how this would cause it, and I haven't ever put any pressure or anything on the back, but i did buy the iMac used, what are the chances of this being ruled accidental damage?I have the bleed in all four corners of the screen, if that makes any difference.
I'm new to this forum and I just bought a new iMac 20" 2.66GHz, I turned on my computer and noticed a weird sound (buzzing or humming noise) not loud but loud enough to here I notice when I messed with the Brightness it went away is there something wrong with that or is that a known issue?
View 16 Replies View RelatedI've got two iMacs in my posession currently from getting replacement machines. Both have screen issues as follows: iMac A - dead & stuck pixels, feint grey horizontal bar running along bottom portion of screen, bottom left corner has noticeable backlight bleed. iMac B - dead & stuck pixels, yellow tinge in bottom portion of screen. So here are my questions. Which iMac should I keep and submit for repair? (does it matter and why or why not?) How does the actual repair get done? For example, if I submit iMac B for repair, could I end up with a grey bar or backlight prob like in iMac A?
Are there multiple layers to the display when they fix specific issues? For example, let's say the dead pixels are on one layer while the yellow tinge is on a different layer, or are both issues on the same layer? I ask because if there are two or more separate layers, there is more of a chance to mess up so I may want to submit the iMac that has the least amount of issues.
Lastly and most importantly, has anyone submitted their iMac for screen repair for these issues and got it back 100% repaired? (no dead/stuck pixels, yellowing, grey bar, backlght bleed) These are #4 and #5 in terms of the number of replacements I've gotten now and I'm sick of it so I may opt to go for repair on either of these existing machines instead of going for replacement #6. But do you think a 6th replacement would be better than going for repair on either of these? Or not?
My wife has an iMac (I don't know any other way to identify it e.g. model number), and she has this 3rd party calibration software that I'm trying to use. I am not used to a Mac, and I cannot find the display settings for the monitor. There are no buttons on the monitor, and when I go to preferences, I can only find the brightness control. I've googled this and cannot find a clear, simple answer. I have used every version of Windows (currently on 8.1 on my PC) and it's easy for me on that platform. I suppose it's just that I don't really know how to navigate Mac OS.
