iMac 27inch Display - Dark on left side :(

http://www.macrumors.com/2013/10/29/apple-hit-with-class-action-lawsuit-over-fai ling-27-imac-displays/

I have the same problem - left side of the screen is dark. This happened after the warranty expired. Very disappointed in apple as I use all their products.

Add me to the list. 27inch iMac 2.7 GHz Intel Core i5, left side flickering and waiting to go out completely. Purchased through applestore with Barclay card...still paying it off. 120 days after warrenty and Genius bar said they couldn't help me. Offered to wave labor and charge $500. I refused. The funny thing is that i tried showing them the posts about the 2009 imac that expieirenced the same problems...didn't read this thread till i got home. So i guess 2009 -2011 27" iMacs are having this problem. 3 years worth of computers with the same screen glitch and they still refuse to admit its a factory defect. Apple needs to recall these and fix the $10 plug that appears to be the problem.

Another one to add to the list, mid-2011 machine bought in mid 2012 [and still under Applecare] has just started doing it this evening. Woke it from sleep and a few minutes later screen brightness dropped, which I found odd because I have the auto-brightness thing turned off. I was running a program that has a dark background, when I minimised it, I realised that actually, it was only the left side of the screen that had dimmed. Put it back into sleep mode, left it a few monents, woke again and screen back to normal, for a few more minutes, and then dimmed on left again. It is now dim, but once or twice has flickered briefly back to bright. I guess I better book an appointment with the Geniuses... just what I need, lugging 27 inches of mac through a shopping centre. NOT HAPPY!! Especially if they have known about this issue for this long.

Yes, that's exactly how mine started. It will get progressively worse, until the entire left side is too dark to even see anything clearly.

I finally brought mine to the Genius Bar in San Francisco, and I was given a blank stare look as I described the problem, and even included a link to this message thread. No sympathy at all. I was told it would cost over $500 to replace the screen. The other option, I was told, was to buy a new computer. Nice.

I asked, "If I pay $500 to fix this now, will it happen again in a year?"

More blank stares.

I wish they would have looked at this message thread so they could at least fake some sympathy.

When I get the final repair receipt, I am going to post it on every social media site I belong to and warn everyone not to buy one of these 27 inch iMacs.

just what I need, lugging 27 inches of mac through a shopping centre. NOT HAPPY!!

Niote, that since it's covered under AppleCare and if you're within 50 miles (80 KM) of an Apple repair station, you might be eligible for an onsite repair since yours is a desktop machine (depends on where you're located). Available in the US, for sure.

Me too....27" iMac. LCD screen replaced once during warranty period. Now 1.5 years later, the second LCD flickers on and off, then goes dark on the left side. Can't afford a repair.

Apple don't care about their customers - that I'm afraid is a fact of life 😟

Same crap with my 27" Mac in Sweden. Out of warranty and I'm too scared to open it in case I make it worse.

The Apple store said they had never heard of this problem...BS! What a joke!

Same HERE IMAC 27 INCH in uk have it from 2011 july just gone dark in left hand side, is apple gonna take care of this problem?????

Same here iMac 27" Mid 2011 Intel Core i5 2.7 GHz in the UK, I have had the unit since November 2011 and I have noticed the problem has got worse over the last year. I refuse to pay for a repair due to this been a manufacturing/design fault IMO.

It started with the top left corner of the display going darker than the right hand side, over time it has got to nearly 50% of the screen being dark (left hand side).

This is my first iMac and I can say I loved it but to me this is pathetic compared to my Windows machine thats been running since 2007 without ANY issues what so ever!!!

I truly hope Apple do something about this, surley with all the stuff on the Internet regarding this they must accept liability for this rubish.

Apple come on admit that you also have a problem with the i5 generation running the Radeon 6770M graphics card!!!!

OVER TO YOU APPLE.

ONE NOT VERY HAPPY CUSTOMER!!!

Put me on the list. IMac, mid 2011, 2.7 GHz Intel Core i5, AMD Radeon HD 6770M 512 MB. Darkened lower 1/3 on the left hand side of the screen.

Add me to this list too - iMac 27inch bought May 2011, 2.7GHz Intel Core i5, AMD Radeon HD 6770< 512Mb.

The brightness on my screen has been flickering for a while now and sometimes the screen would just go black. It has now started to randomly go dark on the left side. It seems that the left side of the computer gets too hot and the screen starts misbehaving...

I've rang my local Apple store and explained that this forum has a whole LOAD of people on with the same issue with iMacs purchased mid-2011, so I can't understand for the life of me how this is not a known problem by APPLE!!! If we are prepared to pay over £1300 for a computer, we'd bloody expect it to work for more than 3 years please... I have been told that if I pay to get it fixed, and they do realise that this is a known problem, they will reimburse the cost of the repair, however I really can't see why I should have to pay for something which is a technical failure on the manufacturers part and something that is affecting many other people!!

For the moment I think I will buy a non Apple monitor and screen share my iMac, which is a rediculous thing to have to do to a computer which is only just 3 years old and cost nearly £1400 to buy!!

Apple please read and respond...

Add me to this list - 27 inch, Mid 2010 3,2 Ghz Intel Core i3. Left side of screen is getting darker by the day. Do the right thing Apple.

I'm adding myself to this list too.

I purchased the iMac just recently from a friend and found that the left half of the screen was darker than the right. I took it to the Garden State Plaza store for repair, I was happy to pay a fair price to get it to work properly since this was a pre-owned machine that I purchased from a friend for a good price.

When I got to the store I told the tech right away that this 27" iMac was part of the class of devices covered under the GPU repalcement program and that the most likely cause of the problem was the GPU and the logic board. I was told they would look at it and make the necessary repairs. After 4 days the store called and I went back in to pick it up. They had replaced the LCD. When I arrived at the store and the tech powered up the iMac in front of me I could see that the screen was now bright across the full width of the screen but now had a bright 1 inch stripe of washed out color all the way around the perimeter of the screen. I was a little confused because they said it was done, but obviously it was not. I assume the tech didn't bother to actually look at the screen before he/she marked it off as complete.

My wife and I had to wait 35 minutes for a 2nd tech to be brought to us to look at the screen, who looked at it and who then called on his manager to look at it as well. We had to wait another 15 minutes for the tech manager to look and he saw what everyone else did, a big bright stripe that shouldn't be there. We asked them what they had done and they claimed that they tested the Backlight and found it to be in order, so they then replaced the LCD. They indicated that they would have to keep the iMac for several more days until parts came in.

4 days later the store calls me back again telling me the iMac is ready, come pick it up. I arrive at the store and as soon as they power the iMac the light stripe is still there. The tech failed again to check on the screen before marking it as complete. I was furious at this point. I had wasted two 1.5 hour drives to get to the store only to discover that they had not done their job. I had paid the store $580 for a repair that they hadn't done properly.

Now the crazy part, the tech du jour tells me that they are going to replace the logic board and the GPU. If you recall, the first thing I told the first tech who received my iMac 2 weeks prior was that the logic board and GPU were most likely the issue. They asked me to leave the iMac again to that they can replace the GPU and logic board, and that it would be ready sometime soon. I actually had to ask the tech to put notes in their system to request they QA the monitor before calling me so that I don't waste another trip. I would have to drop another $200 to fix do this repair which would bring my bill up to $780. Again, going back to the beginning, I am happy to pay for the repair, I purchased this computer knowing it needed to be repaired, so it has not been a question of money. It has not become a question of time, I am losing far too much of it because of Genius Bar incompetence.

I have decided that at this point I am going to ask to speak with the store manager to tell him how dissastisfied I am with their Genius Bar staff and the overall experience I've had with this repair. It's not the cost or the work required, it's the fact that twice the store told me they had repaired something and failed to properly test and verify their work before calling me and having me drive 1.5 hours roundtrip just to leave the store empty handed.
