Currently Being ModeratedFeb 3, 2010 8:12 AM (in response to Smash1031)I too have the same problem. The marks appear to be on the LCD directly in the top left of screen and appear to be growing. Did you get any resolution on your issue?21.5 3.06, Mac OS X (10.6.2)
Currently Being ModeratedFeb 3, 2010 3:56 PM (in response to Shaun Ragnauth)I have it here too. With me it's very complicated though. I had screen problems on two earlier iMac incarnations (a 20 and a 24'') and both were replaced over two years when multiple replacement screens did not prohibit a recurrence. I can understand why they would question my environmental conditions and indeed warned me that if this newest imac ended up having "dirty, smudgey" stains they would not replace it again. I am not a naive or new Mac devote though and I promise you it is not environmental (no nearby cooking, well ventilated, not near a window, non smoker, etc) so I fear I will be on the far end of credibility when I call. On both previous iMacs and their myriad replacement screens it was on the upper left side. This stain of 1.5 inches is on the right side- right of the top center. I do not want to accept this new blemish. d27'' 3.06 iMac, Mac OS X (10.6.2), A Time Capsule, Airport Express, and iPod
Currently Being ModeratedFeb 4, 2010 8:43 AM (in response to Shaun Ragnauth)I haven't contacted apple care yet (extremely busy), but when I do I'll post my experience on this thread. If you do please post your experiences as well. I have a feeling it's related to the "northbridge" heatsink. The upper left hand corner will get pretty hot when in use for a period of time. I just hope this is not a design flaw. We shall see.

Currently Being ModeratedFeb 5, 2010 5:12 AM (in response to swapnonil)Just discovered the same thing on mine, top right has smudge marks from the inside. I also have a slight yellow tint on the screen at the bottom. I really don't want to give the machine in right now as it works beautifully apart from the screen no other issues. Though this is new machine just 2 weeks old its serial number is that of a week 44 one (India does not get a lot of love from apple). Thinking of waiting for known resolutions (for both the tint and the smudges) before taking it in.iMac 21.5, Mac OS X (10.6.2), NVIDIA GeForce 9400M graphics
Currently Being ModeratedFeb 16, 2010 10:04 PM (in response to swapnonil)I have also noticed what look like heat streaks growing at the top left and right of my 2009 24" iMac screen.
The aluminum frame gets so hot at times that it's too hot to touch, except very quickly. Especially in the upper left corner, where the fan blows the excess heat.
I believe these screen streaks are actually burn marks made by the heat. They were not there at first, but they continue to grow as time goes on.
My fans all run at the correct default speeds for this model, but I believe the frame gets way too hot, and I think my screen has been damaged from the heat.
I am going to report this to Apple as well, and will report back with any new info.

I have a 21.5 iMac bought in November 2009.
There appears to be numerous greyish smudge marks behind the glass screen on the top left hand corner.
Can someone please post a picture of this anomaly?Unibody 15" MBP - Mac mini - iPhone 3G, Mac OS X (10.6.2)
Currently Being ModeratedFeb 17, 2010 4:03 AM (in response to DCIFRTHS)visible on the top right (sorry about the bad picture quality its the best my phone can do). these are from the 21.5" iMac.
Currently Being ModeratedFeb 17, 2010 10:34 AM (in response to greenthunderleaf)Same problem here with iMac 21.5 bought 1st Dec 2009.
With a week or so marks appearing in top left corner spreading inwards, and later more appearing around all edges.
Casing does not get hot, only mildly warm after long use. It looks like a static smear of very fine particles. Gradually increasing.
Still within the 90-day warranty, contacted Apple. Guy said he could only deal with software issues and gave me a number for local reseller who could deal with hardware problems.
Called them, they said this problem is not covered by warranty, I have to bring the machine in and there will be a charge to clean the inside of the screen.
Not happy. Very not happy. Is this going to be a regular trot for me?
And if I buy the AppleCare warranty - does that still not cover having these design defects rectified?
Not going to go away quietly on this. These machines don't come cheap.iMac, Mac OS X (10.6.2)
Currently Being ModeratedFeb 17, 2010 10:43 AM (in response to IanSn)But it should be covered in warranty ? no ? I don't think theyre stains on the inner side of the glass, more likely burn marks on the screen or something. A screen replacement is the fix I think, which is covered. I'm not sure however I haven't given mine in, I do not have the time at the moment. I had requested a refund via email instead and haven't heard back from apple, and my dealer wasn't happy when I mentioned a refund, they're more than willing to fix the screen though and said its covered.

Currently Being ModeratedFeb 17, 2010 11:01 AM (in response to greenthunderleaf)At this point I don't know. Just reporting what happened.
Not in London at the moment so there's no store near me, bought it online.
Have to keep hassling Apple. Don't understand what this 'not covered by warranty' is all about.
Things are meant to be 'fit for use' when they are sold, or money back. That's the law.iMac, Mac OS X (10.6.2)
Currently Being ModeratedFeb 17, 2010 11:47 AM (in response to IanSn)Have the same problem with my 21.5" iMac purchased just after release in october.
Didn't notice it in the first two months (had a dark wallpaper) but the smudge streaks, left corner, are getting worse.
I had the same problem with my old 20" iMac, matte screen, but that happened after two years (no Applecare then).
Guess I have to make a call soon, bummer.iMac 21.5", Mac OS X (10.6.2)
Currently Being ModeratedFeb 17, 2010 12:22 PM (in response to swapnonil)I recently bought a second-hand 24" iMac (less than a year old) and noticed the same screen staining being described here. Yesterday I took the glass screen off (surprisingly easy) and repeatedly cleaned the inside of the screen with a mixture of white vinegar diluted in warm water and also a light mix of window cleaning fluid. It took about four goes at cleaning, putting the screen back on and checking the results, removing and repeating the process. I can honestly say that so far as I can see the results are perfect. Whether this state lasts or not remains to be seen.iMac 27" 3.33Ghz, 8gb RAM iMac 24" 2.66Ghz, 4mb RAM, Mac OS X (10.6.2), iBook 14" iPod (3rd Gen)
