    My 24" LED Cinema Display is going black as well. I'm driving it with a late 2008 Macbook Pro. An SMC reset seemed to help but then it went out again. I connected my wife's newer MBP but that laptop isn't working with it either. The computers recognize it and I can move my mouse and documents into the dark space but it's not lighting up. $1000 buck for LEDs that are supposed to last forever? I don't know. My laptop monitor was flickering as well and the firmware update seems to have fixed that but not the display as I was hoping it would

    Hi, II think I have the same kind of problem.


    I have a Macbook Pro 2009 and a Cinema Display 2009 MiniDisplayPort.


    Since 1 week, one day my cinema display works, and the next day I have a black screen on my cinema display. My cinema display is not detected by my macbook !!


    What's the problem ?? I cant use my cinema display !

    Update to previous post. I took my 24" LED Cinema Display to a repair shop. They replaced the logic board, $100 part plus one hour labor. It seemed to be working for two weeks but now it is black again....It will show a brief flash of light when plugged in and sometimes an SMC reset will get it working momentarily.


    The only other option offered was to replace the power cord. Anyone having luck getting these to work?

    I had exactly the same experience. After 3 returns Apple exchanged for a new 27 ".

    I think you should print this discussion, take to your Apple contact and begin to insist.

    The 24" monitor had problems and Apple should acknowledge this by at least exchanging ones that don't work.

    I had this problem (MBP 13 inches) and an Apple Thunderbolt Display that it started but suddenly went black and on again with flickering and glitches. Tried the SMC and PRAM reset and nothing improved. Then installed the latest Thunderbolt firmware update and it worked.


    Thunderbolt Display Firmware Update v1.2

    "false alarm". I thought that the firmware update solved the problem as I was not having more blackouts, but today the problem just re-appeared.


    Apple, this is unacceptable. SO many people having this problem with your Displays. Actually, I have another one and it just went black completely (they claim that the main board fried). 2000$ wasted. I usually love your products but these displays has turned to be the worst choice ever. I want my money back or are least a solution!

    This problem has happened to me with my 2 LED Cinema Displays for a while now; I've just gotten used to it because I'm busy and it only goes blank for half a second. It's as if it just needed to blink.


    It only happens on one monitor -- both are connected to a Mac Pro (the Darth Trash mode), running Yosemite -- but swapping the monitors did not change it. That is, it doesn't matter which monitor I use. Either one will go black, but only one of them: the main one that the menu bar is on.


    I use extension cords, of course, because the %$#@& Apple monitors shipped with a built-in cord that's too short to reach the Mac Pro unless I hide the Mac behind the screens (I won't). I tried a longer cord that fails to carry the USB, so I had to go with a shorter extension cord. USB works, but my main screen blinks out.


    When I swapped monitors to test, I swapped only monitors. That is, I plugged the same USB devices into display #1 that were previously in #2. So if USB is causing it, that might explain why either monitor goes dark when it's swapped.... or maybe it's the ports. I gotta get back to work now.


    The same monitors were previously attached to my earlier Mac Pro (the silver box kind) and I had similar monitor troubles with that.


    I think it's caused by the extension cords, but I see no choice if I want to use 2 monitors.
