24 inch LED cinema Display miniDisplayPort goes black

24 inch LED cinema Display miniDisplayPort (2009) goes black with my MacBook Pro 2009.
It was working perfectly, but one day my cinema display went Black , and my cinema display is not recognized by my macbook !
And when I bring it to an Aple Store, it worked !
It seems to be a random issue.
I can't find what is the problem...
I tried my cinema display with another macbook and it works.
I tried my Macbook with antoher screen and it worked.
Please help me.

I doubt reinstalling the OS will fix your problem but that's you choice.
FWIW I found the following 6-page thread which may be a similar problem to yours but you will have to search through it for relavance or ideas (I didn't read it):

Mid-2012 MBP with 27" Cinema Display SCREEN GOES BLACK WHEN USING USB PERIPHERALS IN DOCK

I haven't been able to find any straightforward answer as to why this is happening and it's becoming one of the most infuriating things in my life, impeding my workflow and costing me unmeasurable time in waiting, rebooting, screwing with cables, etc.
I use my MBP as a DAW for multitracking live audio events to ProTools through a digital console where I work. Here's my gear list that I use every day:
Mid-2012 MBP - Yosemite, 8GB, i7 quad 2.5, mechanical hd
HengeDocks dock for my exact model machine - has set-screw jacks for CinemaDisplay power, Tbolt, FW800, USB, USB, SDcard, headphones, etc
USB wired keyboard
Anker 1x4 USB3.0 hub - I have a TimeMachine 1TB drive, 3TB project backup drive, audio interface and MIDI I/O or PT iLok, depending what I'm working on
Magic Mouse (BlueTooth)
Here's what's happening:
SCENARIO 1 - I insert the CinemaDisplay (cD) power connector and TBolt plugs into the dock, tighten the set screws, close the lid of my MBP (already logged into Yosemite & linked with MagicMouse [mM]) and stick the MBP into the dock... everything comes up on the cD and I can go about my day. At this point, I can plug the USB hub into the back of the cD and the system sees the hub & all peripherals listed just fine.
SCENARIO 2 - Install cD powercon, TBolt connector, USB3 hub, USB keyboard into the dock, close the lid on MBP (again, logged in), insert into dock... cD comes up, looks great for about 15 seconds then goes completely blank. No response from key presses, mouse clicks, threats with a hammer, etc. Then, of course, I have to yank the MBP out of the dock, which hard-disconnects the external drives (backup and TimeMachine... good for them, right?) and causes the MBP to flake, thinking it's still in the dock, then not, then logging me out & requiring a password (not a big deal- I deal with copyrighted stuff, so passwords aren't the issue).
***EVEN IF I DO NOT PLUG THE USB3 HUB INTO THE HENGE DOCK, THE cD STILL GOES BLANK AFTER 15 SEC... IT ONLY SEEMS TO LIKE THE TBOLT AND POWER... NO OTHER PERIPHERALS (fw800, USB, etc)***
It seems like the MBP freaks out when the lid is closed and there are USB/FW peripherals plugged in while using a secondary TBolt display as the main output... seems stupid... if I need a closed-lid dock, the MBP shouldn't care what I have plugged in while the lid is closed. I had the same issues with Mountain Lion & Mavericks and now it's being repeated with Yosemite.
My goal in this exercise is simply to free up the USB jacks on the back of the cD for two reasons - #1) from time to time, I have extra things to plug in and I don't want some massive USB 1x8 hub on my desk... looks stupid; #2) the bottleneck created by plugging in the hub to the back of the cD (another hub via TBolt) almost triples the time required to back up/copy files. I move files from system drive to backup drive & back VERY often due to the nature of my job... speeding up this process would greatly improve my efficiency in the matter. Why would Henge create a dock with all the jacks on it to allow someone to plug into a cD that won't frickin work with said cD? Every other dock I've found makes the user stick the MBP on a slanted, goofy-looking stand and have the lid open or something dumb like that... what I have is the setup I need... just need the USB stuff to work while lid is closed and everything from powercon & cD to USB3 hubs will work without making the cD freak out.
Any ideas out there?

Have now taken the 27" display into the repair shop and after 24 hrs got the phone call - "appears to be nothing wrong with it, will check again on Tuesday and let you know".
I can't seem to find anything on the net describing a similar problem. Everything is working fine right now with the Mac Pro connected to the older 20 inch Cinema Display. In fact, everything seems to be working about a second faster.
I was told by the local retailer that Apple no longer makes the 27 inch LED Cinema Display product and the new display, the "Thunderbolt" will not work with my 13 month old Mac Pro.
***??? In 20 years of owning Mac equipment, this is my first major "uh-oh".

Why does my 27 inch LED cinema display freeze my Macbook Pro when connecting?

Hi,
I've had a 27 inch cinema display for about 2 years now and love it.
However, a good 50-70% of the time whenever I attach my MacBook Pro, currently 15 inch late 2011, rather than waking up the MBP, it just freezes the computer. The same thing used to happen with my 13 inch MBP.
Any ideas why that is?
thanks,
TT

I finally decided to just take my MBP down to the Apple store and see what would happen if I connected it to one of their new ACDs. At 1st, the guy at the Genius Bar told me that my MBP only supported 1280x800 as a maximum resolution. I told him that was for my MBP screen, and not an external monitor. Finally I convinced him to let me connect my MBP to one of their monitors. Low and behold, looking at the Display settings pane I saw some addtional resolutions, including 2560x1600!
So, now I have confirmed that my MBP can drive an external monitor to a resolution of 2560x1600, using just the single mini displayport connection. I just have to figure out what's wrong with my ACD. Suspecting that my older ACD might not support this higher resolution, I did finally discover that my model only supports a maximum resolution of 1920x1600.
Sorry for all the confusion...

MacBook Pro, 27 inch LED Cinema Display and OSX 10.7

I do have a MacBook Pro and 27 inch Cinema Display. To improve the wireless connection I have to open the macbook. Doing so whilst running OSX 10.7 my Cinema Display changes autimaticaly to the settings of the MacBook display.
With OSX 10.6 this was OK.
Is this a bug or does anybody know how to overcome the change in display whilst opening the MacBook ?

Having the exact same issue, same set of circumstances.

How to connect multiple Apple LED Cinema Displays to MacBook Pro

I have an Apple 24 inch LED Cinema display that I run from my MB Pro. I mainly use the MB Pro+ screen for document editing.
I would like to run a second Apple 24 inch Cinema display from the MB Pro. I am presently running another monitor successfully via a Dynalink USB splitter but would really prefer to run a second Apple monitor. I have enquired at two Apple Stores and browsed lots of sites. Multiple monitors from MB Pro seems ok (as long as it's not two Apple monitors). I would be surprised if Apple is content to pass up the opportunity to sell more of these superb screens.
Grateful for any advice and suggestions

In addition to the one from Atlona, there are:

LED cinema display doesn't work under boot camp

I just installed Boot Camp and Windows 7 x64 on a Macbook Pro 2010 (6,2) with and NVIDIA GeForce GT 330M 256MB video card. The Boot Camp drivers automatically installed during the process. I plugged in my 27 inch LED Cinema Display, which works just fine on the OS X side. However, the screen was dark, as if it wasn't plugged in.
Audio does go through the Cinema Display.
I have tried to repair the drivers twice by running the Boot Camp support software. I also tried to run the NVIDIA driver installation software separately. It failed.
So, what can I do to get the Cinema Display working?
Thanks.

I found a solution that worked for me. I deleted from my USB drive the Boot Camp support software that I had downloaded from the Apple website and downloaded in its place the support software through the Boot Camp Assistant program. I ran setup.exe, did the repair option and restarted. I then went to the NVIDIA driver install application on the USB drive and ran it. This time, it worked! I restarted the computer and both the laptop display and the Cinema Display lit up.
Originally, and during the previous 3 times trying to repair the drivers, I saw the ATI graphics driver getting installed. Somehow, it appears that the NVIDIA drivers didn't install before.
I hope this helps others.

Will my 27inch LED cinema display work with the 2014 MacPro?

I have two 27 inch LED cinema displays I bought in 2010 I think. I want to know if I can use both displays with the new cylindrical MacPro? My displays have mini display port connection and are non thunderbolt. I know that I cant daisy chain the monitors because they are NOT thunderbolt, but will I be able to connect both to the new MacPro's coming this December?

Thanks TurboStar for your excellent comments and suggestions. I have pre-ordered that Apple 27" LED Display now off Amazon.co.uk... it will be in stock on the 21st March.... and I look forward now with anticipation to getting my hands on it and more importantly my eyes... now that I have read your resounding approval of the 27" compared to my tired and jaded 30".
Interesting your comments about the new MacPro also... I think I went OTT when I bought my last 12 Core MacPro (32GB RAM + 512GB SSD)..... it cost me in total €8,800 ($12,200) which was mad money.... it's doing a great job.... but I don't work with video or video games, just Quark, Illustrator and Photoshop... so not sure if the 8 Core or less would have done the job just as good... I just wanted the best with what I thought was the most horsepower so I could take on any task. I will wait and review more with the New MacPro.... maybe the 6 Core is the way to go... and pump up the SSD and RAM....
Thanks again.
Regards,
Anthony
PS. Have a grrreat Paddys Weekend!!

Does your new 27" LED Cinema Display buzz?

Got my 27 inch LED Cinema Display yesterday: very nice monitor.
However, I have noticed a feint buzz/ticking coming from the bottom right of the monitor when the brightness is set high. Just loud enough to be VERY annoying!
Is this a feature of the monitor? Does anyone else's new 27" Display have a buzz?

yes, the reason it sounds like the electromagnetic interference that induces tones in speaker drivers (such as the microwave energy from cell phones) is because it is essentially the same mechanical action... which is a resonation electromagnetic coil (which will produce tones at whatever frequency it is vibrating).
The specific tones that it is producing are dependant on the electrical properties of the circuits attached to the coupled device - but it's probably possible that particular properties could cause the coils to create more than a single tone (just like a speaker)... on mine the tone didn't quite sound singular, but since the amplitude was analogue to the brightness i guessed that this pointed the transformer.
It used to be such a serious problem in inductively coupled conductive devices that it could shake the devices to pieces. These days it's only really an irritation in terms of noise - but it remains necessary to design the structure and housing of these devices to dampen and minimise these vibrations.
In much larger transformers the noise is very noticeable (have a listen the next time you pass an electrical substation).
... i could be wrong but it's a common problem in electronics and i think it's likely.

I have a macbook connected to LED cinema display. The display started to flicker. The display turns black for a second or two. Sometimes I restart macbook and display. Sometimes it helps.

same issue, either your wiring or display itself is going bad. for me, it was the display but luckily still under warranty

Under Windows 7 Ultimate x64 and Boot Camp, my 27 inch Apple LED Cinema Display checks out as a Generic PnP Monitor and is shown as NOT HDCP compliant. I haven't been able to find any kind of an .inf file to use. Does anyone have a solution?

I am having this same issue. Im not sure if this is the cause but I think this is keeping PowerDVD Ultra 11 from playing back Bluray under Windows 7 / Bootcamp

LED Cinema Display (27-Inch) and the new iMac (late 2012)

Does the LED Cinema Display (27-Inch) work with the new iMac (late 2012) as a second monitor, and if so, which cable do I need?

It will work. Plug its Mini DisplayPort plug into the computer's Thunderbolt port. No adapters needed.

HT1338 Today when connecting my MB Pro Retina Display to my 27" LED Cinema Display instead of mirroring (which worked fine in the past) both screens are black with a large arrow cursor. I'm unable to resolve this. Anyone have a similar experience?

I think what may be your main issue here is that the 2011
server has the Intel integrated HD3000 and is is struggling
to run both a Thuderbolt display and a second monitor.
When looking at specs for Thunderbolt Display, it is stated
that the 2011 Mini Server can only support one. Adding that
Dell monitor with 1920x1200 display may just be too many
pixels for the HD3000 to handle.
You may want to try setting the Dell to a lower resolution
to test the theory to see what happens. It is however,
possible that any additional monitor when using the Thunderbolt
display may over tax the HD3000 graphics.
FWIW personally, I have been running a 2011 Mini Server w/ Thunderbolt
display for almost a year now without any issues. However, I don't
use a second monitor.

Difference between a Apple LED Cinema Display (27" flat panel) and a Apple Thunderbolt Display (27-inch)?

May i know the difference between a Apple LED Cinema Display (27" flat panel) and a Apple Thunderbolt Display (27-inch)? both products look the same to me, even the prices are the same, but the name of the product is different. Its so confusing! I want to purchase a secondary display for my 21" iMac, but idk the difference between the two.
furthermore, another question i have is, is 27" the largest display i can get? is there larger ones (just the screen, not the computer)?
please help, thanks!

One has thunderbolt capabilities, the other doesn't.

No you can get a larger one. Maybe not an Apple one, but certainly another brand.
