    Hy everybody!

    Since a week I'm experiencing some issues on my 27" iMac (mid. 2011).

    There are three strange things that occur.
    • Screen flickering.
    • Vertical lines (blue or gray)
    • Vertical lines magenta transparent
    • White screen
    • Black screen

    It all started with a first screen flickering, and after a reboot it worked again. Now, I'm getting screen flickering and right after vertical lines. Sometimes they're blue, sometimes gray. as of shortly i was able to get to the login-screen and after entering my password, the flickering and the vertical lines came up. Now the flickering starts as soon as the login screen or the rotating circle appears.

    What I've done so far:
    • Reset PRAM
    • Reset SMC
    • Start up in save mode (at first i was able to boot up here, but now i cannot)

    Btw. I'm out of warranty :-( I'd like to fix that myself if the problem is not the logicboard

    I'v made some photos and videos to show you what I'm exactly talking about.

    I'd say something is failing on the hardware side of things and your only option is to take it into Apple for diagnosis and repair.

    Understood, but if it is hardware (and the odds are extremely high it is) then there's nothing else for you to do. Live with it as best you can, or have Apple work on it.

    If you bring it in, at least you can get an estimate of the cost and then decide if its worth the repair or time for a new computer.

    Hi ad-on-is,

    Either GPU or Logic Board. Like maflynn said, take it to an Apple Store. Even though you're out of warranty they'll be able to diagnose the issue and issue you a repair quote. That way you can decide whether or not it's worth repairing. If you don't want to go ahead with the repair quote then you can get it back unrepaired.

    Plus the whole affair is free of charge so it's definitely worth doing.

    Cheers.

    Unfortunately, there are no "Apple Stores" in Europe, which offer such services free of charge. They're just so called "authorized Apple reseller" and they account a charge for nearly everything. for diagnostics 100€ (130$) :mad:

    May I ask where you're based, please? I'm in the UK and there are quite a few official Apple Stores pottering around. Hopefully we can find something near you.

    it's similar to what happened with mine (late 2011 27" iMac). Mine was also out of warranty. Transpired the display was broken and needed to be replaced (they tried replacing the backlight board first, but that made no difference).

    Total cost to me was £450 :(

    It's a known issue with 2011 27" iMacs (search the Apple forums). Apple, however, have yet to acknowledge it.

    Had same screen issues with my previous 2011 iMac. Lucky I was under Applecare at the time. Definite hardware issue. First Apple replaced power supply, but still not solved. Next was screen replacement, still not solved. Then graphics card, still no luck. Then they were going to replace the logic board, but before this happened, the gave me a new iMac in exchange.

    Could be one of several things and unless you have it diagnosed, it will be hard to tell what is wrong. The money a reseller charges up front may look like a lot, but in the end it is better that having something replaced and still having the issue. Which will cost you more in the end if it does not solve the problem.
