Q: 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.

iMac 27inch 3Ghz 4GB 1TB ATI 4670, Mac OS X (10.6.1)

    Some seem to have hopes when next week there's a "press meeting" from Apple (introduction new products?...iSlate??..tablet?).
    I sure hope that one or two questions will be asked considering the iMac problems.

    Just talked to Apple.
    My replacement i7 iMac (originally scheduled for delivery january 14th, then changed to january 21st), has now been delayed for the 3rd time. This time its been scheduled for delivery on january 28th, arriving somewhere around february 4th.
    I asked if the problems with the iMacs had been resolved. She said they had, and the new iMacs are all fine.

    Thanks for that info Ady-baby.



    MistaSmiff was also told by someone at tech support that the problem was solved.

    But I think that we will never know for sure if this is real until Apple issues a statement saying it as found the cause and fixed the problem.



    Until then, one can only hope to get a good unit when going for an replacement.

    Many users here have been told that there replacement units would be Ok and then receive an other faulty unit.

    Sorry to disappoint you all, but my week 47 i7 iMac received in mid November is still going strong
    No flicker
    No Yellow tinge
    No dead pixels (screen and camera)

    PERFECT!

    @atlatnesiti

    There is nobody on this form thread that would be disappointed in learning there are problem free iMacs out there. We all want one and are waiting for more positive reports before we purchase again or send our iMacs in for another repair.

    If your intent is to post snarky self serving remarks please go away.

    My point exactly Gille!



    Different responses from different service people!

    That's not a confirmed solution.



    Until there is an official confirmation of a solution, we are left hoping that we will get a good unit when we go for a replacement.

    I visited the Apple store in Charlotte, NC this week.
    Staffer had the gall to tell me he had NOT heard anything about the worldwide iMac flicker debacle. Even as a returned 27" sat on the Genius bar from a replacement swap! LOL.

    Forget it! There's no taking to the guy. He posted that he was not posting again several times & keeps on coming back. He has no friends! He's lonely. But instead of trying to help & make some friends, instead he brags about his so called perfect iMac to tries to shove it in our face. He's very immature. He claimed I couldn't read once, but he needs to use spell check. In the post where he claimed I could not read, there were 3 misspelled words.

    Simple solution - Get It fixed or replaced

    What is the recommended course of action. As stated before, I just got my week 2 imac a week ago and got the flicker yesterday. Should I open a case with support, go to the apple store? I can't really afford to send it back and wait 3 weeks for a replacement since I've got a business to run. Is it a good idea to open a case now and wait to send it back until the problem is really fixed or just wait until the problem is fixed to open a case?

    Thanks for your feedback.

    In my previous post I let the group know that my iMac was sent in for repair and I was told by the Apple tech that they could not repair it. They also I formed me that a replacement could not be guaranteed at this time to not have problems. As I stated earlier, I will wait a month, see what the good people on this thread and others like it are reporting, and then I will purchase again.

    Once more. If you have a perfectly working iMac please tell us; this is good news. We are Apple fans and are not bashing Apple. We all want iMacs, but we want iMacs like yours with no issues. Please keep this thread productive and informative and not insulting.

    Get life, get married, have some kids, forget spell checkers and relax
    BTW: My i7 - received in mid November is PERFECT.
