iMac Intel Core2Duo Mac OS X (10.4.9) 20" - 2 Gigas Ram - 256 Vram

hello xiti, and welcome to the club!
Looked at your picture, looks exactly like my screen, and again the lower left corner. I'm thinking about having my display exchanged next week, but I'm afraid unless Apple acknowledges the problem and changes the material of the rear display cover, those dark spots are always going to come back sooner or later. I asked several local Apple Authorized Service Providers recently, they all claimed to have no knowledge of this issue.

The club, yes… I would prefer to not subscribe ;-))
I"m agree with you, I'm not hurry to send it to apple if they can't fix definitively the problem ;-( The end of my guaranty is 10/2007 so… But now, I hesitate to take an AppleCare ?! Maybe is it that Apple wants ;->

I have the same problem , too

Weird marks on the screen , but no cleaning gets rid of it

This is the last integrated mac I will ever buy , it's a mac mini via my Sony bravia or a Mac Pro from now on.

The whole integration thing may save on space but there's too many inherent limitations in the whole idea behind the all in one imo.

Mine has the same problems too. Will probably get it replaced before the warrenty expires, but i've had this issue before on my ti powerbook and the repacement screen was a disapointment and had a red hue to it.
So hopefully thier not replacing the screens with B grade parts?
I think its a heat issue? Would like to no more!!!! 🙂

"So hopefully thier not replacing the screens with B grade parts?"

Hi Mac Adict!
Does your warranty state that replacement parts will be new parts? Mine doesn't.

in the mac spanish forum one user has cleaned this dark areas, you can find a guide of imac screen cleaning in pdf with photos.
its seems that the hard disk or the processor heat are causing this dark areas, but it can be cleaned openenig the imac with isopropylic alcohol.

Could someone translate this document ? 🙂

I have exactly the same problem... but i have my iMac for more than a year, so its out of warranty. Anyone had it fixed by Apple when the product is more than a year old?

If your iMac is out of warranty and you didnt buy and register AppleCare for iMac/eMac (or something similar) before the end of the warranty, the Display replacement will be very expensive.
You could wait and hope that Apple offers a general repair extension program for concerned customers, but no one can promise you this will really happen, time will show.
You could also ask in one of the local Apple Stores, if you have one near to you, or via phone call.

I am joining this unwanted club. Se we are at least 14.

And you are right Steve310, this might be caused by the heat. When i touched my screen, it's warmer than other corners.

My iMac 20" core duo is one month to due the warranty. I am going to ask my nearest apple store, if they willing to give me a replacement.

Is there any DIY solution fir this problem?
My warranty is a month away, and i need my iMac. If i send it to Apple support i won't be able to work.

the same here, small grey spot in the down left corner!

i have iMac only one month so i have warranty.

but, will that fix the problem? will it happen again?

is this happening on every single iMac, or these are just exceptions?
if this is happening to only few of them, what caused that?

cheap manufacture? China? Error in assembling?

I have this issue on my 24" c2d iMac in the upper right screen (my right when facing it) and a bit to the left of the camera. I'm taking it in this morning. It started about 3 months after purchase.
I see this link has good pics of the fix process.

I printed it off and am taking it with me. I'm nervous as heck cuz if they replace, I don't want a screen with dead pixels, etc.

I've got the same problem on my Aluminium Imac 24", but its a right gray spot in the middle of the screen. It measures approximately 20cm...

😟
