New iMac 27inch screen flickering/tearing/shutoff

I have been experiencing some problems with the all new iMac 27inch display.
At non-fixed intervals i will get one of the following:
Screen distortion/flicker somewhere random in the screen (feels like it is more in the lower part) that looks like a horizontal bar of about 2-3inches just popping in and out of the screen.
Screen will go completely black for a second and then come back on. Sometimes 2-3 times in a row.
Somebody else already made some video-clips about these problems, I am experiencing exactly the same behaviour.

Just to not that in the course of writing this post my screen has flickered 13 times and has gone black 2 times.

I received my 27" iMac three days ago and ever since i got it out of the box and turned it on it has done the same as the video shows.
Last night i watched a 30 min programme on BBC iPlayer and the 2-3 inch white lines kept popping up every few seconds horizontally across the screen. The screen also went black momenterally on 6 occasions.
I cannot believe after three days that this problem is so bad. I spome with Apple this morning on the Apple Care line and they told me to:
1. Shut down and take out power cord for 20 secs then turn back on.
2. Shut Down and then hold down "D" when turning back on which performed a hardware test...
Both had no effect.
Luckilly i am still within the 14 days of recieving my iMac and they are sending out a replacement but i am worried that this machine will have the same problems...
Is anyone happy with theres and is anyone not experiencing this problem... There seems to be a big issue here???

    Hi Brett L,
    thank you for the coordination of this helpful thread. Are you Apple? If yes, please allow me to ask you three questions:
    1) The Display Firmware stopped for over 90% the flicker issue, but what has this Firmware changed exactly?
    2) Is Apple preparing a fix for the yellow tinge?
    3) When will it be save to buy a new iMac?
    Thank you for your efforts.
    Hello Citrus.
    Excellent questions.
    I hope that Apple will authorize Brett L. to provide us with some clear, honest answers to them . . . although, as I pointed out before, it would seem by the latest messages that have been posted in this thread -- that is, the *original thread* -- that through their actions, Apple has already provided us with their answer -- and solution -- to the yellow tinge issue; and that is the replacement of the LCD panel.
    As to what the most recent display firmware update did, I am doubtful that Apple will allow Brett to reveal that kind of information, but we can be hopeful.
    As far as when it will be safe to purchase a new iMac, I seriously doubt that Apple will say anything which would suggest that it is not safe to purchase a new iMac now. What company is going to say "Don't buy our product now. It's not safe"?
    For my part, I have now contacted Apple regarding the issues that I am having with my 27" iMac, and I will wait over the next few days to see how things play out. Based on the testimonies of others here, I don't expect Apple to disappoint. I have the confidence that they want to leave me a satisfied customer who will continue to purchase their products in the future.

  • IMac 27inch screen flickering

    The left bottom side of my 6 month iMac 27inch gets flickering and darker, and if I press on the screen, it gets the correct lightning. What should I do? Is there any way to repair this by software? Or do I have to call apple care? thanks

    Flickering would be covered by the warranty. I would recommend buying AppleCare though, you can find it discounted by doing a little searching. For example on Amazon I see it for about $130.00

  • IMac 21" late 09: Slow, screen flickering/tearing and odd behavior - the problem that puzzles everyone

    PLEASE HELP!
    My iMac 21" late -09, started acting a bit wierd a year ago. Things got worse rapidly, it got slower, the screen flickers/tears (see link below), short moments of lost internet connection, lost connection whit the keyboard (might be keyboard that is broken), almost overheats when gaming and odd behavior on some webbsites whit galleries and/or videos.
    Let's begin whit the screen: it's not vertikal lines or major distortions, just a subtle horisontal line that "wanders" from bottom to topp and some lagging from time to time. Looks like this: http://cl.ly/3i2W2o3S1D2T
    The wierd thing is that hi-res does not mean more "tearing". Yes the lagg and risk of tearing increases, but the connection seems to be: lots of movement=tearing. So a pixeld 240p video of people dancing can be way worse than a news debbate in1080p!?!
    Lost connection whit internet and keyboard rarely happens and is probably due to something else, but thought that was good to have in mind.
    Odd behavior: galleries ex: when browsing images on Facebook in fullscreen, the image sometimes jumps around in the beginning and when clicking on next the same picture might appear again or just nothing at all. When scrolling down overwiewing a gallery, the updating stops and you can't scroll down further. This problem appers mainly on FB, deviantart also acts a bit wierd but there is often small issues whit image sites. Doesn't help to switch browsers either!
    Videos: Youtube is horrible to use, stops loading, dosen't start loading, erases everything loaded (grey bar disapears and reloads), refuse to switch ressolution and suddenly stops the video like it was done! "ehh.. wasn't this 2min long? Not anymore, now its 34sec!". Mainly a Youtube problem but many similar sites can be a bit problematic to use.
    NO, it's not the HTML-5 problem or any standard flash issue and using a different browser dosen't help!
    Worst is the fact that most of these errors are not constant! One day your watching youtube or mabey a movie in VLC, a bit laggy, but almost no problem. Next day **** brakes lose and after 2hours of struggling you are ready to stabb yourself in the face!
    What i tried: Most easy buggfixes that might cause the above problems, updating most things, Switched from OS X SL to OS X ML, complete reinstall and some things i probably forgot by now. Then went to MacStore for repair, they didn't find anything wrong and said it worked fine after the standard diagnostic/repair program!?! Went home and everything was the same! Went a second time to MacStore, same result.
    So I'v reinstalled a few times and it seems to improve the Mac. But 2-3weeks later every error is back, even if I barely installed or downloaded anything!?!
    Any idea what this could be? Or is the graphic card broken and MacStore has a blind, inbred muppet as a technician?

    No I didn't. The first time i explained the problem thoroughly and thought that they just couldn't miss such a visual error. I was wrong. The second time the technician wasn't there so i showed the above clip to the salesstaff and explained everything onceagain. Later the technician called me and we talked for 10min.
    Btw, the problems always "manifests themselves", just varies between strenght and frequence.
    But all other issues aside, what could cause the tearing of the screen as seen int the above clip?

  • IMac 27inch screen shutoff

    hi my iMac 27inch screen shutoff automatically. Sometimes I can wake the screen up again but sometimes I can't. Sometimes the screen just turns back on after a few minutes. I sent it back to the place I bought it. They say the either the motherboard or the screen is broken. I have to pay something around 800 dollars to repair it. It almost half price of the computer. Is there any other solution to my problem? 

    Only if they are wrong about the screen or motherboard being broken.
    How old is it? And you did not get apple care when you bought it?
    Had you gone to system preferences>energy saver and adjust the time before the screen sleeps?
    The "turns back on" kind of is a bad sign for you though... Sorry I am unable to help at ALL.

  • Which new Imac 27inch model is better?

    I was looking to upgrade from a MacBook Pro to the new Imac 27inch. I was looking online and saw that the lower 27inch 2.9 ghz model runs the same or a little better than the 27inch 3.2ghz model. Does anyone know if this is true and does anyone have some suggestion on which model to get?

    Both are Intel i5 CPUs so, the 3.2Ghz CPU should be faster.
    If the 2.9Ghz i5 CPU model was tested with the Fusion drive, it may have been faster, but that would mean that the 3.2Ghz CPU model would be even faster with the Fusion Drive, too!
    Purchase the best and fastest iMac you can afford.
    Plus, with the 3.2 Ghz CPU model you get the faster 1GB VRAM GPU.

  • 24" iMac Silver - screen flickers

    Just pulled it out of the box today. I can't operate at anything less than full brightness or the screen flickers. I can't find any other posts on this one. I see a lot of other related issues. Anyone having this issue? Did it go away?
    I can't lose this machine to apple for repairs.

    same for me, When I try and use the main system brightness control at the lower levels the display tends to have uneven strips that are lighter and darker.
    its like if the monitor turns on and off very rapidly, like high speed blinks, i use an app called SHADE, it dims the monitor (dont now how) the screen dont flicker anymore and its free

    Unlike other solutions, Shades doesn't change your display settings, and won't screw up your monitor's colour profile.
    BY THE WAY, MAYBE ITS A PROBLEM RELATED TO THE FREEZING IMACS DUE TO THE ATI GPU
    fine app, right price

  • Imac 2009 screen flickers in lion

    It's back!  Since upgrading to Lion, the infamous 27" 2009 iMac screen flicker has cropped back up.  Its not so often, and usually not too long after it wakes up.  Anyone else seeing this?  What to do?

    Actually, I've just noticed that it also flickers if I tap the right spot during the BIOS bootup (gray screen when laptop first turns on). Disabling the SMS in MacOS didn't make a difference, so I'm going to assume it's hardware and get that logic board that's troubling everyone else replaced...
    Thanks for your help...

  • New iMac 27" screen issues!!!

    Does anyone experiences this situation on their iMac with new "Screen LaminationProcess" ? 
    After leaving a white image still for couple minutes on the screen (Example: Web Site), a sort of halo remains.... This is noticeable when I working on applications with gray GUI's like Adobe Photoshop, Aperture, iMovie... pretty much any application.
    I am kind of upset because the computer is only 1 month old and I just noticed this problem. Besides, there are some awkward brighter spots on the edges of the display… it seems like there is a leak of light from the inside out. That cannot be shown on the screen shots but they are bery anoying when watching a movie... ;(

    You really should call AppleCare first.  Let them be aware of the problems you are having.  You will get a case number.  Keep it in a safe place.  It just may come in handy if the exact same problems crop up in the future after your warranty runs out.

  • IMac freezes, screen flickers, simply power fails or restarts when visiting Javascript "heavy" pages in safari

    For the last couple of updates in Mavericks I'm having an issue on my 24" iMac (early-2009).
    Whenever Safari wants, it makes the screen show some graphical glitches and everything but the mouse are inoperable and that only to the extend of moving the cursor, because clicking doesn't do anything. Some other times the machine just crashes, on some few occasions it has even told me there was an error and has send an error report at apple.
    I tried disabling all 4 of my safari plug-ins and reseting everything in Safari, but nothing changed.
    Then I started playing around with detecting what might be causing this, so I have come to the conclusion of it being a JavaScript (or JQuery?) issue.
    Since I'm a programmer and a web-designer, I tested it on a few webpages created by me and I soon noticed that if I try to stretch out the usage of let's say a slider by clicking fast on the "next slide" it caused the issue.
    After that I checked and saw that indeed the more JavaScript calls a page has the more the chances of Safari "crashing" (I'm using quotes, because not once has simply safari crashed, that would be an improvement in my case!).
    All other major Browsers (Chrome, Firefox and Opera) don't seem to cause this issue, neither has this happened on any other occasion but when I'm working on Safari.
    Any ideas on what might be causing this and/or how to fix this?

    BTW, do you have any third party RAM installed? If yes, try removing and check for issue.
