Currently Being ModeratedAug 9, 2009 6:17 AM (in response to Motionworks)I have the same problem here on a Mac Pro 2,66 GHz Quad and a NVIDIA GeForce GT 120.
The problem is: the signal cable is way too short (only about 1m). After having lots of discussions with Apple support about this issue, Apple just told me to buy an extension cable. The only cable available in Germany comes from Dr. Bott, so I bought their 1m extension cable,
My screen sometimes went black before installing this cable, but with this cable installed, things got worse. Now, the Cinema Display goes black one time per minute approx.
It's just a shame that Apple completely ignores that the signal cable is too short for many people that put the display on top and their Mac below the desk...2009 Mac Pro 2,66 GHz Quad-Core Intel Xeon, Mac OS X (10.5.8)
Currently Being ModeratedAug 10, 2009 1:06 AM (in response to Mario Rasch)Meanwhile, it seems I found a solution for my problem.
I used some binders to bind together my 1m Mini Displayport and a 1m USB extension cable. Alas, it seems the Mini Displayport signal is very sensitive to interferences from other cables. So, after removing the binders I did not get any black screens so far.2009 Mac Pro 2,66 GHz Quad-Core Intel Xeon, Mac OS X (10.5.6)
Currently Being ModeratedAug 10, 2009 1:30 PM (in response to Motionworks)Alas, I have to revise my last posting: I am getting fewer black screens now, but still my LED Cinema Display goes black form time to time or show some graphical distortion... Seems I have to contact Apple support again...2009 Mac Pro 2,66 GHz Quad-Core Intel Xeon, Mac OS X (10.5.6)
Currently Being ModeratedAug 19, 2009 10:24 PM (in response to Mario Rasch)Another thread with more users having the same probem...Apple needs to fix this with a firmware update or something! Replacing the monitor with a new one does not fix the problem according to a couple of other people.

Currently Being ModeratedSep 23, 2009 9:36 AM (in response to Motionworks)i have the same problem with a brand new rig (2 weeks old). LED Cinema Display driven off video port on rear of 24" iMac. Almost like it recycles or something. Randomly blacks out and comes back to life.

Currently Being ModeratedSep 28, 2009 11:04 AM (in response to janericster)I had this problem . I think it would happen once/twice a session every few days or so. I've installed OS X 10.6. It happens much more frequently now – every day. I think it may only happen in a period after I boot up and then stop.MacBookPro 15" build 10B504, Mac OS X (10.6.1), 24" Cinema Display

Currently Being ModeratedDec 15, 2009 1:56 AM (in response to Motionworks)Hi, i'm having the same annoying problem. I have a macbook pro (jan 2009) attached and Snow Leopard updated 10.6.2.
Sometimes randomly audio stops to work on 24" Led Cinema Display, even if in System Preferences the sound is on the correct option. Sometimes a momentary black screen that turns on automatically after 2 seconds. It's difficult to find a solution, because it happens randomly.
Reading posts here, I tried to unplug the usb, tried to remove the usb hub attached rear the display, tried to change the plug from UPS to the wall socket.
Now everything works, but... how long?MacPro 2006 / MacBook Pro 2009, Mac OS X (10.6.2)
Currently Being ModeratedDec 15, 2009 8:21 AM (in response to Francob)We purchased two new 24" Apple Cinema Displays a few weeks ago along with a new MacBook Pro 15" 2.66GHz. We are using the Cinema Display's built-in mini display port to connect it to the MacBook Pro. Within a few days of setting up the computer, we've encountered the following intermittent faults:
1. Cinema Display flashes black (completely) for a couple of milliseconds;
2. horizontal white lines (1 pixel to 100ish pixels high) flash across Cinema Display.
The MacBook Pro can go for hours with no problem at all and then start a fit of flickering. The MacBook Pro's internal monitor is not affected by any of this. The problem occurs with the MacBook Pro attached to either of the two new Cinema Displays.
We reported the fault and Apple who provided a replacement MacBook Pro. The new computer is doing the exact same thing. We raised it again with Applecare yesterday and installed a Cinema Display firmware update (OS X 10.6.2). The flickering stopped for the rest of the day, but today it's started flickering again!
We also have a one year old MacBook Pro 15" 2.4GHz running OSX 10.5.8 which works perfectly (no flickering or cutouts) with both Cinema Displays.
Apple have now assigned an Engineer to our case and asked us to install some monitoring software (Capture Data / TimingSnoop). I'll update this post if/when Apple resolve the problem.MacBook Pro 15" 2.66GHz / 24" Cinema Display, Mac OS X (10.6.2)
