Dark spots on display iMac 5k (Late 2014)

The same problem I have with me and my brother on iMac 5k Early 2014!

I have an iMac 5k Early 2014, 2 iMac 5K have the same problem,

to me is less dust, with her brother's unbelievable!

It all happened after a year, when we lost a guarantee from Apple, the whole family all use Apple devices, after this, Apple will never again see my 1 cent! This is a shame, we have paid more than 3,000 euros per piece!

All of their devices I hung up for sale, since that's why! iphone 6, iphone 6 plus, iphone 7 plus, macbook air, macbook pro, ipad air 2, imac 5k!

After cheering from the iMac 5k, after a year of disappointment, at least all of their services are charged too expensive! 2017 is the year of Apple failure! trust me on this!

I have the same exact issue. I think Apple should do an out of warranty repair because this is due to a defective hardware. Here is the picture of my late 2012 iMac.

The 2 bottom corner are affected. It is only obvious when there is a white background. Very irritating that this beautiful machine has a permanent mark on it.

Same issue here. I have an iMac 5K 27 inch late 2015 model. After 13 months of my purchase, I observed grey smudges at bottom right corners of my screen, and they are visible if I open a light colored window. It's a bad luck as this machine is not in warranty anymore.

Apple should consider this issue seriously as this should not happen with a machine which is many times costlier as compared to other brands's desktops in the market. A consumer buys an Apple product because of the trust on its quality, not just because of its brand name.

Apple have issued me with a warranty exception and are undertaking the repair for free. Suggest anyone experiencing the same fault call AppleCare and refer them to this thread and hopefully you'll get a similar outcome.

GOOD LUCK!! its happened to 3 of my imacs - including the late 2013 with “ new “ housing. Apple does NOTHING to fix this- mine seems to show up weeks after Applecare expires- I paid 2300.00 for a POS and they want 600.00 to replace the lcd ( the only solution ) but its not a permanent one- same issues occurs after a few months. COMPLETE DISGUST with Apple

Yes, I am. My Apple Premium Reseller gave me 3 Years warranty when I bought my Imac in May 2015. You would think I’d be lucky, but the reseller says this is “cosmetic damage”, which is not covered by their warranty. I won’t give up though.

Good to hear! My Apple Premium Reseller gave me 3 Years warranty when I bought my Imac in May 2015.

Did they replace your screen already?

Same here, but after going through this complete discussion thread, it seems like nobody has yet got any permanent solution to this..... don't know what to do now? Do anybody know if this causes any harm to the display functionality or if it continues to grow?

I just looked at my receipt and my applecare ran out a few days ago. Rotten luck

Think it would be worth checking in with apple regardless?

Yes. This is obviously an Apple fault. Don't take no for an answer. In Australia we have laws that apply to defective equipment that is "not fit for purpose". See what your country offers.

I've just had the same issue here in the UK.

The iMac is 2 only years old (late 2015) and therefore out of warranty with our consumer laws. I was quoted £520 to replace the panel in the Apple Store.

I had to jump through hoops with several online chats and calls to Apple Care who eventually agreed to cover the cost of the repair. The repair was completed within 7 days.

Looking at this post and several others it seems this issue is quite a widespread. The technician in the Apple store said that they don't see this very often which I didn't really believe.

They didn't explain the cause but I'm assuming it's probably caused by either insufficient insulation from the speakers or a fault in manufacturing with the panel.

Although I'm grateful for Applecare for covering the cost of my repair, I really think that a repair program should be initiated for anyone else with the exact same issue. The defect seems to be apparent in all slim models since 2014. In the models before that, the screen could be easily removed and cleaned on the inside.

I was going to buy my daughter an iMac for her birthday but until either the cause of the issue is rectified in future models or there is a repair program in place, I don't think I can in good conscience buy another iMac knowing that it will be case of 'when' and not 'if' the panel becomes defective.

I had this happen in the first 6 months of having my iMac, got the screen replaced and it showed up again on the new screen a few months later.

I waited in the very last month of my Applecare running out before taking it in, since it takes close to 2 weeks to get back.

And now it's happened again! At this point I'd just really like to get to the bottom of what is causing it. I was wondering if it could be the speakers causing it because today was the first time since I had it last repaired that I think I've played anything over the internal speakers.

Magnetic fields from speakers are not supposed to damage LCD panels.

I’ve had a look at images of the internals of an iMac and the dark marks always occur in the panel in the exact same location of the speakers at the bottom left and right corners.

It seems pretty obvious that the issue is caused by insufficient shielding from the speakers over time.

It’s very unlikely that it will happen by playing music on one single occasion.

I guess it would have been difficult for Apple to test the effect of the speakers being next to the panel over a long period of time when they probably are only able to test new devices over a period of a few months.

That being said, they really need to own up to having cocked up the design and set up a repair program for damaged panels.

Hi Rapheal, I got no responses from anybody so I did some research and have established that it's dust that's entered the iMac on the intake vents at the bottom of the computer and has got stuck in between the screen and the LCD. The only way to remove it is to take the thing apart and I certainly don't have the skills or the confidence to do this, but see the youtube video:
