    I just noticed something that looks like stains/clouding/darker zones in the lower corner areas on my 7 month old iMac 27" (late 2015). What is going on, can anyone advise? IMG_2663_S.jpg IMG_2660_S.jpg

    I guess it is repair time, I contacted Apple Authorized service, and they said they will have to replace the screen assembly. Bad thing is it needs to stay in about 15 days.

    15 days without your computer and who is going to compensate you for that? And what if the problem comes up again after they replace the screen?

    I know it is too long, it is my main machine. I asked if they can shorten the service time. I am still under warranty for another 1 year and 4 months (2 years where I live). If the problem comes again, it better be during this time.

    Not for nothing, that time frame is usually the worst case scenario and they tend to turn around repairs faster then that. I think they say such a long time frame just in case something happens or there's an unusual back log of work.

    Mine's been replaced (over a year ago) and looks like that again. It's a late 2012 model.

    Same thing with mine. Bought a late 2013 27", had these dirty dusts inside the screen and after the replacement, it came back again. It is actually between the LCD and the white filament. It is repairable on older iMacs (magnetic), the later models need to have its full screen replaced. Thought the geniuses at Apple have fixed this flawed design.

    The last two posts are not very comforting. I am wondering how is that even possible, as anywhere I looked it is said that the glass and the LCD panel are fused. If they are fused, aren't they supposed to be sealed properly so that no dust or other particles can get in-between? I looked at the ifixit tear down, and examined the display assembly. I could see black tape around the edges, with some visible gaps - if that is the seal, there is no wonder why dust gets in. Has anyone ever attempted to un-fuse the glass and LCD panel? How are they fused - are they glued together?

    It's a major reason why the iMac isn't a fully functional professional machine. If you rely on the screen, and this happens, you can't easily swap out the screen. Bye bye goes the computer. Unfortunately, Apple appear to have abandoned, or demoted the Mac Pro to yesterday.

    Well, OK, but it is unthinkable to manufacture such an expensive 5K screen that allows for dust to settle in-between the LCD and the glass. It is beyond my comprehension.

    This is insane... madness.
    Whatever it is, it is just not right. When you manufacture a display assembly where the LCD is "fused" to the glass, NOTHING should be able to come in there.

    I am taking the iMac to service tomorrow. It is a 250km drive one way. This will be the 4th trip I am making for this iMac: 1st to buy it; 2nd to take it back because the camera was not working; 3rd to take it fixed... and I will make a 5th trip to take it after it is serviced now. All in all, it will be 2500km travel for this iMac for the 5 trips.

    I feel you. That's the problem of owning an iMac, you can't service it yourself. I still find it amazing how this problem isn't as well pronounced as the problem with the latest 5K LG monitor.

    The LG 5K stand-alone display problem with WiFi router. LG is also the supplier of iMac screen.

    FYI, the screen assembly was replaced, and it took 15 days.

    I had the exact same thing on my late 2012 21.5 iMac, it started showing after a couple of months, how it's possible if it's laminated, at the beginning I thought I could ignore it but it got worse I decided to send it a week before 1-year warranty end. Got the screen replaced, it took over a week. But a year later it got the same, and now I have to live with it, and it is so annoying. I was thinking about getting the 5K 27 when it will have vega graphic, but for that much money and the screen needs to be replaced every year, you can get max 3 years warranty, I would like to keep the computer over 5 years.

    Mind, this doesn't always happen.

    I had the clouding in my 2008 (IIRC) iMac, tried to fix it myself and ruined the machine completely. I have a Hackintosh now. Lovely thing. Cost me €1300 including screen. Anyway. Husby's 2011 iMac has no problems whatsoever. No dust at all. It's concerning to read that those issues STILL pop up in new models. Maybe the iMacs are so thin because they smoke a lot of cigs?

    Just had my screen replaced on my 4 year old iMac (late 2012)
    Took my machine in on Monday to my local Apple Store and it was ready for collection the next day.
    My display was replaced free of charge under EU Consumer Law

    How? Why? Can you tell me more, please? I thought it's 2 years here with the EU Law.
