Dear All,
I bought my iMac last August, less than a year, but I found there are many black or grey shades in my iMac. Yes, it is "in" not "on." It is not on the surface. One can clearly see the "dirt" is behind the front glass of the iMac. It spreads all the way on the top of my display.
Seeing is believing, and these are the pictures, though not very good:
Worse, it is not the first time. I have another iMac, and it has the same problem right in the middle of the display.
For your information, these two iMac's are not in the place - one is at home, and the other is in office. Also, they are not used by the same person. Therefore, the reason is unlikely to be misuse or accident.
Does anyone has the same problem? I hope I can just fix it by myself instead of sending the iMac's back to factory to repair.
Thanks in advance.

Mac Pro, Mac OS X (10.6.6)

    I have the same thing on my early 2008 iMac. Mine appeared right about the time when my HDD died and the screen developed a dark shaded spot right over that spot. I suspect it was heat.

    I would take it in and see what they say. Some people get lucky, but at my local Apple everyone appears to be abusing their products and they do what they can to not help if it costs them money.

    My 27" late 2009 iMac has gone half dim on the left side. I am not experiencing "dirt" however half of the display is dim, the other bright. It also flickers, which is just as annoying. I am very frustrated and going to take it in to the Apple Store this Sunday. Based on previous 27" display topics, I'm almost leaning towards asking for my money back. This is just ridiculous.

    You will not get your money back unless it has been 14 days or less. The dimming effect sounds more like a backlighting issue. However, you should take it in.

    What you're seeing is fingerprints on the back side of the glass.


    You can remove the glass with a couple of suction cups (it's held on with magnets and guide pins), it can be removed easily.  Once removed, simply clean both sides of the glass.

    I am experiencing this issue (left side dim), and am looking for answers...

    Do you have a mysterious white powder on the back of the computer? A fine white powder on any electronics nearby. If so, we share the same problem. Something is leaking out of the computer (electro-statically, I'm assuming). I want to know how dangerous this is to our health! I've had this stuff in my apartment now for 6 months. I've been breathing this crap!

  • Doug Metz Level 2 Level 2 (325 points)

    No...  I don't have any mysterious white powder.


    Maybe the people upstairs spread talcum powder on the floor to stop the boards creaking, and it's falling on your desk?  </sarcasm>


    Seriously, if you've got powder coming out of your iMac, you really should take it in immediately... don't wait half a year.
