I made this subject like this so people can easily find this thread and comment.

 

Exactly as it says, my iMac 2011 27inch i7 purchased in Feb this year,

about 2 weeks ago the screen started to flicker,

but now the bottom left side of the screen is darker than the rest of the screen, sometimes it will start to flicker again and then (when the room is quite) I hear a noise like a florescent bulb illuminating and the screen comes back to its correct even illumination for a while and then it can happen again any time.

 

I spoke to Apple today and of course they said bring it in and we will have a look at it and if it needs repair it could take upto 10days, which i don't like the idea of.

 

 

 

I know there are plenty of posts on this subject but i can't see any recent ones that can answer my 3 questions:-

 

1. Has anyone seen this problem this year ?

 

2. How long did Apple Store take to repair the fault ?

 

3. What was the actual failure, i'm guessing it would either be the display or the graphics card ?

 

 

Cheers..

    I have had exactly the same problem with my imac 27 inch i3 purchased new in November 2010, with these display problems starting 5 months after purchase.  Entire left half (although more so at bottom left) of my screen suddenly becomes darker, usually after a few seconds of display flickering.  I have not yet contacted Apple but will do so before warranty period is up.  Did you have your problem resolved and find out what it was due to?

     

    Thanks,

    Andre

    And another one! This one bought in February this year - I think its a ' mid-2010 ' version so it seems a problem. Back to Apple with it  I guess - its not very good is it?

    I brought my iMac to an Apple Store about a week before the end of my 1 year warranty period.  The display was replaced free of charge and I was able to pick up within 1 day so was very satisfied.  The display works well again.  Hopefully won't run into the same problem; I bought AppleCare just in case to be covered for another 2 years.

    I just had the same problem occur.  Bought the 27" iMac in June 2011.  It's been flickering for a few weeks, the left side of screen just went partially dark.  Seems like a common issue.  Hopefully it will be replaced as should still be under warranty.

    I had the 27" display replaced last year. Took four days. BTW, if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

    My 27" iMac, bought March 2011, has just developed an intermittent screen flicker, and occasional reduced screen brightness.  Very disappointing and annoying.  

     

    A newish problem after purchase, may well justify requesting compensation under the UK 'Sale and Supply of Goods Act 1994', I believe.

     

    We are NOT impressed!

    I have had the same flickering issue, intermittent for months with occassional full black-outs, and now the monitor has a full dark patch (basically making this computer unusable). After speaking with Apple Support, I now have to lug in the computer for unknown repair, I am not happy!

     

    Does Apple expect you to just stop working and shut down your business for four days? Apple should be more communicative with their customers (I've been an Mac user/purchaser since 1991) about what the problems and solutions are.

    If you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine. You didn't provide any details, but there are only users here, so we can't tell you what Apple expects. That's for you to determine.

  • skullcat Level 1 Level 1

    Thanks Baltwo, but unfortunately after speaking with a rude Apple support rep, the only option for me is to lug the machine over for a repair.

  • baltwo Level 9 Level 9

    Rude? I've not had that experience. I'd call back and ask to speak to a supervisor, then report the poor behavior.

    I'm having the same screen flicker problem with my mid-2011 i7 27 inch iMac.  It began about a month ago with just a very occasional flicker.  Now it's four or five times a day at least but the left side hasn't gone darker yet.  Guess I'll have to take it in to the nearest Apple store. 

     

    I've also noticed that the overall brightness at the middle settings is now considerably darker than when I first got it.  I've had to boost it to about 75% instead of just over half.  100% looks the same as when it was new.  Strange!

    Sounds like I have the same issues as everyone here, I purchased the i5 27"  this past spring,  it was

     

    supposedly the first batch of the updated versions of 2011, it too has been flickering the past few weeks, the

     

    entire screen would dim slightly then brighten back up, while using it this evening the entire LEFT half of the

     

    screen went dim and hasn't returned to full brightness.

     

    Also about the same time the flickering started , I noticed that shortly after I put my monitor to sleep it would turn itself back on

    Update:  OK, now my left side of the screen is also going dark when it flickers, same as everyone else.
