Q: 24" LED Display with 2011 15" MPB

Hey all,

I've had this 24" LED Cinema Display since it came out and have been using it with a 2010 MBP until now - I upgraded to a 2011 15" MPD (2.3 Core i7 with high-rest matte display) and now with this new MPD, I intermittently get the 24" LED display turning all black before going back to showing my display. It's happening pretty often. Is anyone else experiencing anything similar?

MacBook Pro, Mac OS X (10.6.6)

    @loyalwhite Apple gives warranty on repairs (I believe it's 90 days). So, if the same problem recurrs within 90 days after a 'repair', the problem exists under warranty of the repair. In that case they should only charge you for the initial repair until the problem is solved.

    The same thing happens to me as well. My 24 inch cinema display goes "black" for 1-2 seconds then comes back on when it is connected to my brandnew 2011 13 inch MBP. The "Geniuses" at the Genius Bar at my local Apple Store are totally worthless. They "pretend" to have no clue about this issue. Give me a break! The discussion boards are full with comments about this issue. So, how can it be that this is NOT known to Apple? Liars!!  I really don't feel like dragging my display to the Store where they may or may not be able to recreate this issue. Appearently, they don't want this to become an issue but it is. Does anyone have similar experiences? What did they do about it? Does anyone know of a classaction lawsuit regarding this issue? I would appreciate any help regarding this issue.

    I have the same issue with both of my 24" ACD.  One of them is worse than the other.

     

    I went the genius bar a few weeks ago and was told to look for a software update.  That night I updated my MBP (2011 15" 2.3Ghz, SSD) with the software patch (just released) and still no help. 

     

    I called applecare support and was told that I would need to wait for another month before a fix would be released through software updates, and was told how much apple cares about early adoptors and so on.  I'm right in the middle of the busy season for my business and with a crappy display, I'm unsure what I'm going to do at this point.

     

    A class action wont get you anywhere, the 24" isn't a current product and if apple wants to say its not compatable with thunderbolt, I'm not sure we'd have a leg to stand on.

     

    How did some of the others get apple to trade up to the 27"?  Anything is better than this one....

    I talked to Apple Care. They didn't tell me to wait for a software/firmware update. I was told to drag my ACD to the local Apple Store. Well, I am not very thrilled about that. Especially since the local Apple "Genius" claimed to never have heard about the "black" ACD screen issue. I can only hope, that they will be able to recreate the issue I am having with this piece of s@#t. If not, what are my options? Does Apple really care about us users? I am starting to doubt it. I might consider seeking legal advise regarding my options.

    According to what I know its not a Cinema Display issue, but a thunderbolt issue in connecting to the display.

    Folks,

     

    I was on the phone with Apple support last night to cross off any software issues before they upgraded my case to obtain an exchange for the new 27" ACD.

    Upon "looking up" the issue, both techs that I spoke to this week although hadn't personally seen the issue themselves before, did say that Apple has become aware of it so breathe easy folks...

     

    The recent software update was supposed to resolve the issue but clearly hasn't so it is their duty to provide any  service that WILL resolve the issue...

     

    The standard process seems to be:

     

    - Ensure Software Updates are up-to-date

    - Run software diagnostics to ensure Mac OS is working correctly.

    - Run the hardware diagnostics to ensure Mac is working correctly.

    - Reinstall Mac OSX REGARDLESS of results from the above...

     

    I strongly recommend doing all of this before calling them so there are no more troubleshooting options remaining except upgrading to the 27" ACD.  Otherwise you'll be handballed from one person to another...

     

    HANDY HINT: With your 24" ACD plugged in, go to the System Profiler on your Mac and under Thunderbolt on the left, check if your ACD is listed as being connected.  Mine said 'nothing connected' but was obviously connected... THIS IS A CLEAR INDICATION OF INCOMPATIBILITY BETWEEN THE MINI-DISPLAY + THUNDERBOLT PORTS SO USE THIS AS EVIDENCE WHEN YOU CALL THEM PEOPLES!!

     

    Good luck to all!

    Yesterday I did an EFI firmware update with my 27" iMac. The 24" ACD is still flickering and having black outs.

     

    Xaidex hint is a good one, in the system preferences on my 27" iMac TB the 24" ACD is not recognized by the system.

     

    It is starting to look like the new TB ports are not displayport compatible.

    Better make some screenshots of the Appple website to make sure you can proove Apple says TB is compatible with Display Port.

     

     

     

    From Apple's website:

    "And because Thunderbolt is based on DisplayPort technology, the video standard for high-resolution displays, any Mini DisplayPort display plugs right into the Thunderbolt port. To connect a DisplayPort, DVI, HDMI, or VGA display, just use an existing adapter."

    If you've read all the threads about the 24" ACD, you may have noticed that the problem is not new, and has started before TB port. In my own case it started with a 15" late 2009 MBP. It's just worse with my two new 2011 MBP. So, in my mind, it's an ACD issue, defective design or manufacturing. Apple should replace all the defective displays, because they are not able to repair them.

    While the display may not show up under the Thunderbolt tab in System Profile (nothing connected), it does however show up under the Video/Displays tab, as rightfully so Led Cinema Display.

     

    I too have had contact with Applecare last week, after having this problem from day one, and they told me to wait even further. Also supplied me with contact information.

    I have been seeing flickering and black screens for months now with an ACD 24 and a MBP 15" early 2011. But when I connected the display through an Atlona Displayport Switch to the MBP the issue went away completely. I'm using the screen with the MAC and a PC now. I have no logical explanation for it since the switch is powerless and does not convert the signal digitally. What I did do is only to connect the video cable to the MBP but no USB cable and no power supply (using the one that came with the MBP). Haven't seen any flickering or drops so far. Maybe this could help someone. That's the switch I'm using:

    This isn't a fix, but I've found if I unplug the USB cable and only have the MDP cable plugged in, the flashing goes away!  I always got a lot of noise through the speakers in the ACD with the USB cable connected.  The camera didn't work either over the USB cable.  This all seems to indicate that the USB portion of the all-in-one cable screws things up.

    @dpedpe Unplugging the USB cable doesn't work for me, glitching and black outs continue.

     

    Let's hope Apple finds a solution soon because this is really annoying me.

    Okay, what I think now is that the issue has nothing to do with logic boards, software or LED panels. If you ask me it comes from the power supply/USB/video signal triple cable. A matter of faulty contacts and bad plugs, especially the silly thunderbolt. The cable components of the ACD can be replaced easily and are cheap. Maybe someone in contact with apple care can give it a try. My warranty expired and I'm fine with just using video with my screen. I use it with PC and Mac, PC sound connected with a separate USB cable and no flickering so far.
