Cinema Display not detected

I got my 20" Cinema Display back from repair today (backlight problem) and now I can't get my MacBook Pro to detect that it's attached. While it was at the repair center, I used a CRT as a second monitor. So today, I just closed the MBP (didn't shut it off, which I think is what cause the problem), disconnected the CRT, connected the ACD and opened the MPB back up. Completely black screen, with the little LED on all the time.
So, troubleshooting:
- The MBP still detects the CRT
- ACD is detected by both a G4 and G5
- A different 20" ACD is ALSO not detected by my MBP
- Reset NVRAM and SMC
- Booted MBP in safe mode
- Booted MBP from startup CD
- Tried various resolutions while the CRT was connected, thinking maybe it was stuck on one that's not compatible with the ACD
- Moved and recreated the com.apple.windowserver.* files
I'm running 10.4.9 and here's what the graphics/displays info says, WITH the Cinema Display connected:
ATI Radeon X1600:
Chipset Model: ATY,RadeonX1600

Been messing with this for four hours, and I still have a blank display. Any other ideas? From one thread someone mentioned replacing the logic board fixed a similar problem.
MacBook Pro Mac OS X (10.4.9)

UPDATE:
I just got back from my visit to a mac genius. Of course Murphy's law was in full effect! With my MBP connected to the cinema display in the Mac store, everything worked as it is supposed to.
Well, I rush home thinking that maybe mine would now work - - no luck! He did suggest that I try connecting analog with the provided dvi-to-vga adapter. This suggestion DID work! BUT, I want my video digital! That is why even though I was happy with the iBook G4 that I bought last year, I wanted digital video + expanded desktop!
I think I will make another reservation with the Mac Genius, but this time, bring my monitor. Will keep you posted...

20" Apple Cinema Display not recognised after upgrading to OS 10.8.2 (Mountain Lion)

20" Apple Cinema Display not recognised after upgrading to OS 10.8.2 (Mountain Lion).
Hello Apple! Anybody there? How long does your community have to wait for a solution?
The same problem has been unsolved for months now. No statements from Apple either.
I was told today to wait for 10.8.3. This might solve the issue. I can not belive my ears.
My MacBookPro 4,1, Intel Core 2 Duo with 2.5 GHz Processor and Graphics chip: NVIDIA GeForce 8600M GT, will not talk to the exter. 20" Cinema Display ( Model Number A1081 ). The screen stays black. Resetting the PRAM did not help. I removed the 'com.apple.windowserver.plist' and the 'com.apple.windowserver.OE35739etc,etcxxxxxxxxxxx.plist', but that did not help either.
Any other solutions, or do I have to downgrade or give up on Apple Computers alltogether after using them for over 25 years?

I found out that I needed a $100 mini displayport to dual-link dvi adapter to make my $30" cinema display work with my macbook pro
http://store.apple.com/us/product/MB571Z/A/mini-displayport-to-dual-link-dvi-ada pter?fnode=51
When I found out that solved the problem, I took it back because that was too expensive for a stupid adapter, and it still didn't work perfectly.

Older Apple HD Cinema Display is detected but no picture

Forgive me, as I know this is an often-asked question but I have searched and can't find a response that fixes the issue.
Yet.
So I have a Mac Pro (circa 2008) that works fine. The Apple Cinema Display is even older from about 2004 (I think).
Everything was working fine and I was video editing and Photopshopping to my hearts content.
I had noticed that recently the display would not come back from sleep without rebooting the computer.
So that might have been an early clue.
Then this morning I came home from taking the kids to school and the Mac Pro fan was running loud and no image on screen.
I rebooted the computer. This time the monitor displayed black and white vertical lines.
"Oh joy," thought I.
I rebooted again.
This time nothing but the heart of darkness.
Nothing.
I reseated the video card (as that has been a culprit in the past) and rebooted. Still no image. Did all the PRAM, unplugging the computer, waiting a minute plugging back in, plus all the other keyboard tricks one reads about. Still no joy.
I then tried the monitor on my MacBook Pro to see if it was a computer issue or monitor issue. No image from the MacBook Pro either.
The Macbook Pro did detect the display though and showed it along side theMacbook Pro screen is the Display Prefences.
I also ran the MacBook Pro in Traget Mode to the laptop so i could run diagnostic checks and repairs uisng Apple Utilities and Disk Warrior. No problems were detected on the Mac Pro (tower).
I then connected a Samsung monitor (that the kids watch Netflix on) and that worked fine on both the laptop and the Mac Pro tower.
So I have isolated the cause to the Apple HD Cinema Display. The video card and other hardware tested out fine.
Any thoughts on a fix or what the issue might be?. I can get by with Samsung as I am on deadline - but would rather have my trusty Apple Cinema screen back.
Many thanks.
And good karma to all who give it a head scratch.

Yeah I use my screen saver more often now and yes it's the white windows and desktop icons that ghost the most not horrible and my warrant is a few years past. The genius is wrong to accuse you that's just plain silly. The first apple 30 inch I bought had green lines and after a few trips to the store they sent it off to be repaired but in the end I think I got a different monitor back. Three and a half years later this started to happen. It's like short term burn and it's pretty subtle. I'm an audio guy so if I were a graphics person and this was my main rig I would be more upset. I just hope it does not continue to get worse. I have an older 22 inch with the clear plastic and it does not have the issue. It only starts to do it after it's been n for few hours.
Good to know I'm not the only one, thanks for posting.

Internal display not detected. "Detect displays" option now gone...

Hello!
My MacBook Pro will not detect any displays. After going to sleep a couple of nights ago, and bringing the computer out of sleep, the display would not turn on; even though I could hear the computer wake up and the fans turn on.
I hard-reset the computer and the display still would not turn on after the power down. Was able to connect to my computer through my wife's MacBook through "Share Screen", and everything is working except the display. I immediately backed up my data realizing the system was working fine (not a hard drive issue, hooray!) other than the display. I tried connecting my computer to an external display and did a restart with the lid closed and the computer would not detect the external either.
Through share screen, I then went into the Display Properties and to my surprise noticed that the "Detect Displays" button has disappeared! Furthermore, when I go into
"About This Mac > More Info... > Graphics / Displays"
Nothing is listed for the screen! On my wife's MacBook it lists the LCD's resolution and other information, but not on mine. Also, under "Display Connector", hers says "Status: No Display Connected"; where as mine says nothing at all, its blank underneath the words "Display Connector".
I reset the P-RAM and that did not help either. If I could I would do a fresh install of OSX, but I can not see the screen so I can do that either.
Is there any way I can reset the computer by any other means?
I also don't have an issue with taking this computer apart, as apple care is expired, and I've done my fair share of take aparts before.
Once again, the computer is starting up and working, but the screen is not being detected or turning on. Everything else works. I called apple and they wanted me to pay $50 for an over the phone troubleshoot, or to take it in to the apple store (an hour away from here) and possibly pay $300 for it to be fixed. AHHHH!
Thanks.

OK, I am confused...can you see an image on an external display or not?
The torch/flashlight trick will tell you if the backlight is out and you are still getting an image and it is a display problem. Although dead backlights are less of a problem with the LED backlit displays.
In your last post you say "If I could at least detect an external...", this leads me to believe that you are not able to detect an external display. With this assumption, it looks like the video card, which if memory serves me correctly is on the MLB and would require replacing the MLB.
If you are able to get an image on an external display, then we are back to the display as the problem.

Built-in camera in Cinema Display not recognized after SL Install

Is anyone else having this problem? After installing the Snow Leopard upgrade, my system no longer recognizes the Cinema Display build in camera, not in iChat and not in Photo Booth. Help!

What I've done is create a new admin user account in System Preferences Accounts pane
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8235.html
after upgrading to Snow Leopard. The new account is using default settings (for Snow Leopard), so it is a good basis for comparison tests. Your issue would be a good use for it.
After creating that new admin user account, log out and log in to the new account. Try the thing that does not work, in the new account. If it works in the new account, the problem is not technically Snow Leopard, but some conflict with something in your existing pre- Snow Leopard user account. It might be some user preference file that you have to trash or some background process that is conflicting, but you can focus troubleshooting on your normal user account as the cause.
If it still does not work in the new account, then the problem is likely to be a bug in the overall system, or a hardware issue.

23" Cinema Display not working. Please help!!!!

I recently purchased a dual 2gHz MacPro Tower and a 23" HD cinema display (both factory refurbished by Apple). Everything worked flawlessly. Then...
I was away from my computer for about a week, during which time both the computer and the monitor were powered down the entire time.
Now my CPU boots fine, and I can hear it responding (when I raise and lower the volume, etc.) but the ACD won't fire up at all. The light on the front isn't blinking or anything, and I'm just wondering if there's anything I can do (I've already reset pram, replugged everything in, restarted several times, etc).
I've also done the ULTRA obvious stuff like brightening my display (which does nothing). I don't know how a less-than-a-month factory refurb that's been off for a week could go kaflooey, but any advice is greatly appreciated.

I'm having a similar problem although it may be USB related. It started with my 2 year old 23" display not waking up when it and the computer (3 month old 15" Mac Book Pro) were asleep overnight. The first two nights this happened I'd restart everything and it'd all be fine. The next couple nights I noticed that if I just unplugged the USB cable from the display into the computer, it would all wake up and function just fine. Today (the 4th day or so, and the day I finally have time to research what the problem might be) the display won't start up at all. There is no indicator light (and never has been in these situations) on the ACD. According to my Display menu bar and my system profiler, my computer definitely recognizes that the monitor is attached (although this was not true the first time the ACD acted up). My mouse also acts as thought the ACD is online... I have now adjusted brightness, and unplugged absolutely everything and replugged it all into a different power source. Still no go... Haven't had a chance to buy a new brick, not really sure that'd work for me... any ideas?
If it were the brick- based on what I've seen on the back of my ACD, it doesn't even look like you can disconnect the cord?
and just a side note... in exploring this problem i noticed that you can choose what the power buttom on the ACD actually controls in the Options menu of the Display System Preferences... is this only for older OS's? because my display preferences has absolutely no Options menu in it...
Thanks.

20inch cinema display not working via ADC?

Heres the specs on my Mac
Dual 450mhz Gigabit Ethernet Model
OS X 10.3.9
1.38GB SDRAM
ATI 128 video card -----> now nvidia GeForce 4 MX
The Story:
I have had my G4 since it was new. I bought it with the 17" Studio Display and it has worked fine. and still works fine with both video cards mentioned above. I bought a used 20" Cinema Display. I saw the display working off an ADC connection before I even paid the guy. I brought the monitor home and tried it out. It loaded to the grey apple screen and then went blank. After some research I found out the ATI 128 only supports up to 17" display. So I got a nVidia GeForce4 MX, put it in my machine, fired it up and I get NO DISPLAY AT ALL! I plugged the 17" back in and it works just fine.
Also the guy I purchased it with threw in the apple DVI to ADC adapter, so I plugged the monitor into my Powerbook 1.33mhz and everything works just fine in mirror and dual display modes.
I am stumped. Can anyone help?
Thanks,
Jus

Hey guys,
I don't know if this will help, but here goes. I bought my 20" Cinema Display with the first G5s to come out ~ 9/2003. Lightning came in on my G5 thru the ethernet port and it wouldn't boot up. Frustrated, I unhooked everything and let the setup sit.
About a month ago I bought a G4 off ebay. It had a video card that had a DVI and VGA port--I guess it was an aftermarket upgrade. I was itching to try my 20" Cinema Display on it. So I bought the Apple DVI to ADC adapter ($99 thing). Hooked it up and sweet, screen real estate for days!
Came home a couple of days later, woke the G4 from sleep, and the Cinema Display stayed blank....f*!
I was p**d! I spent nearly $1200 for the thing, plus $99 for the adapter. I tried unplugging and plugging the adapter/display/G4 per the adapter instructions, still blank screen.
Well, today I had 3 different 22" LCDs in my newegg.com shopping cart and was ready to fork out $200-$300 for a new LCD with a DVI connection. I was convinced it was the adapter. So I thought I would try to hook the setup up 1 more time before I pulled out my debit card. I looked at the instructions again, and noticed apple pictured plugging the power cord into the adapter box first, then plugging the power cord coming from the adapter into the power source, then plugging the display into the adapter box, then plug the DVI cord from the adapter into the G4s video card (DVI-I port), then finally plug the USB cord from the adapter into the G4.
I powered up, and low and behold, I worked!!!
I'm typing this post on my 20" Cinema Display right now.
Only two things I can figure is setting the G4 and display to sleep is no good. The display and/or adapter seems not to work well with the sleep function. So I set System Preferences to never sleep for the display and the G4. Second, could there be a sensor where the power cord plugs into the adapter box? That's the only step I did different this time.
Sorry so long winded but if I can help out i want to 'cause I know how frustrated and sick I was about a having a kickin' $1200 display on the blink.
It could be just a coincidence, I'll repost if the Display goes blank again.
peace,
Danny

LCD 20" Cinema Display Not Working on MBP

Hi people!
Somehow, the Apple Cinema Display (LCD) of 20" isn't working when I plug it to the MBP (late 2011). The monitor remains black after pluging it. Sometimes is detected by the MBP, and sometimes it isn't. Quite random thing. Same hapens when I'm in Windows, through Bootcamp. The weird thing is that I've never had this problem before and it was like being each time more often that the monitor isn't detected. Nowadays, it seems that it won't work. However, the minidisplay port is okay, as well, the monitor.
I use the monitor for work, so this is delaying my work each time more. Please, I need a solution for this since my physical existence depends on this.
Thanks,
Ø3

UPDATE:
When I plug the external monitor into the MBP, the MBP automatically switches to the discrete graphic card, but the external monitor keeps black and also, the mouse pointer doesn't move to the second monitor, like if it wasn't really detected, even if the MBP automatically switches to the discrete graphic card.
Please, I need help with this.
Thanks,
Ø3

Apple HD Cinema Display not working

Hello everyone, I bought a used Apple HD Cinema Display a few months ago and I have been using it with no problems in Leopard with my white macbook (late 2007). I have recently installed XP using bootcamp (the display was not connected at the time of install) and now I am unable to get the display to work in XP. All I get is a black screen. Can anyone help me with this please? Are there any drivers that I may need to install in XP to allow it to work?
Thanks!

24" LED Cinema Display not working with Mac Pro

I have a Mac Pro (2 x 2.4 GHz Quad-Core, model identifier MacPro5,1) purchased in late 2010 and a 24" LED Cinema Display. The Mac Pro has three video ports--a full-sized DVI and two mini DVI. When I plug the Cinema Display into either of the mini DVI ports, I cannot get a picture, although the iSight camera works fine. If I plug another monitor into the full-sized DVI port the computer believes that is the only monitor. The Cinema Display works fine with my MacBook, so there is nothing physically wrong with it.
Is it not possible to use this monitor with a Mac Pro without an adapter, even though the Mac Pro does have mini DVI ports?

Apple 23" Cinema Display not supported by Windows Media Center Edition PC

Well I'm learning the hard way and of course that is through experience. I just found out after purchasing my 23"Apple Display and talking to the Apple Support Tech is that Apple does not support the Cinema Display with PC's,
Wish Apple would be more transparent on this issue prior to a costly purchase. For example on the Apple site listing the Display in system requirements:
Windows PC and graphics card that supports DVI ports with full single-link digital bandwidth and VESA DDC standard for plug and play setup
Well I have a Windows PC with a Nvidia Graphics card just as the system requirements state. Yet my PC will not adjust to proper resolution for the Apple Display. The graphics card works fine. Its a driver issue where the Apple Display is not compatible with Window Media Center Edition on Windows PC's
So in conclusion the system requirements for Windows PC's that Apple is stating For Apple Cinema Displays is not correct. The system requirements need also to state that the Apple Cinema Display does not work with Windows Media Center Edition (MCE)
Hope that helps for any users with Windows Media Center Edition thinking or already have purchased an Apple Cinema Display.

Well,
Here is the latest from Nvidia Customer Care educating users on the DVI port on the Nvidia GeForce FX 5200:
"...The basic difference you will see in these ports are in their Physical appearance. The DVI-D has less pins compared to the DVI-I port connector. Also the Apple 23" Cinema Display will work at a resolution of 1920*1200. But this graphics card that is Geforce FX 5200 will not support this resolution of 1920*1200. It will support only till 1600*1200. So that's the reason you were having the issues were you were not able to adjust the resolution"
So I ask, which Nvidia GPU card can I substitute for the current one at a reasonable price? I don't need dual link, so single link would be sufficient for my application . Here is some more helpful tips from Nvidia support. Hope this helps other users, utilizing the Apple 23" Cinema Display"
"...go for a Geforce 7600 GS graphics card which is a AGP 8x compatible graphics card. This graphics card is just 129$ graphics card. Please visit the given link to know about the details of this graphics card."
http://bfgtech.com/7600GS_512.html
And now for the final conclusion of what you need to know regarding DVI ports. Evidently Nvidia uses a term called normal DVI port. I've never heard of that term in the literature in shopping for a graphics card and checking the specs. I guess you need to look for the specific term single or dual link specifically. If it doesn't say that, then what I can gather it is a normal DVI port...whatever the heck that is?
"...Yes let me inform you that the Geforce FX 5200 graphics card does have one DVI port and one VGA port. But these single link and Dual link DVI port is totally different compared to the normal DVI ports. As you wanted to connect an Apple 23" Cinema Display to this graphics card. So for this you will need to have a graphics card which will have a Single link or Dual link DVI ports not the normal ports. So to support an Apple 23" Cinema Display, you will need to have either a Geforce 6 series or the Geforce 7 series graphics card. That's the reason I gave you the list of graphics card which comes with Single or Dual link DVI ports, not the normal ports."
Oh well off to the market to pick up either a Series 6 or Series 7 Nvidia Graphics card. The Nvidia Customer Care team was very helpful and replied to my inquires very quickly through email.
Hope this long drawn out expose helps others who might have issue with connecting their proud Apple 23' Cinema Display to their PC

Macbook Air hdmi display not detected

Hi, my 2011 Macbook is not detecting my hdmi display - the screen flashes blue briefly but no display is detected in system preferences or anywhere else.
Any ideas?
+I am using a mini display port to hdmi adapter with the thunderbolt output and I've tried rebooting with display plugged in and my osx is 10.7.5 Lion.
Any help appreciated

Actually I fixed it in the end by getting a new cable, it turned out that for whatever reason my cable was not up to the job.\
I found that a cheap £5 one piece thunderbolt male to hdmi male cable off ebay did the job well and it was my two piece - thunderbolt male to hdmi female attached to a standard HDMI to HDMI cable which caused the problem.
Seems like HDMI can be quite fussy and either it works or it does nothing, no in between.
So my fancy mac now works great with my cheapo alba hdmi tv i paid £25 for and carries both sound and video!
(I don't think I'll go back to windows if I can help it, not after using a mac. Once you've had a mac you realise what a pain in the a*s windows is .. I hardly ever feel like punching my mac )

2005 Apple Cinema displays not able to show movies with new iTunes

ITunes is giving me the following error when trying to watch movies on my 2005 Apple Cinema display(s).
The selected movie won’t play on one of your connected displays.
This movie can be played only on displays that support HDCP (High-bandwidth Digital Content Protection).
Try moving the iTunes window to a different display. Make sure the entire window is on the supported display.
I called the Apple support, they said my displays can not support HDCP. Can anyone else comment on this?
Is this true to the best of your knowledge?
Is there anything I can do to make my movies play again? Other than buy new monitors of course.
Thanks...

Hi,
Highlight one of the applications that cannot be updated and click File> Get Info. Make sure you are signing-in to the iTunes Store with that Account Name shown in the Get Info window.

24in LED Cinema Display not charging MBP Late 2011

Hello All,
My new Macbook Pro (Late 2011) will not charge when connected to my 24in LED Cinema Display. The power indicator on the menu bar says "Not Charging" and the LED in the magsafe cable is dim. Is this a known limitation of the older Cinema Displays?
Thanks,

I had the same problem. I found this
https://discussions.apple.com/thread/2006045?start=0&tstart=0
.. which suggestes "wiggling" the magsafe connector a little. It worked for me.

24" LED Cinema Display not working on new MacPro with GT120 graphics card

Dear All,
I have recently purchased a new Mac Pro Quad (2.66 GHz, 6mb DDR3 1066 MHz RAM) with a 24" LED Cinema Display. When powering up the computer for the first time, the display was blank. I swapped it out with a 23" Cinema HD Display, and it worked fine, so I thought it might be the LED Cinema Display itself. However, when I tested the LED Cinema Display on my MacBook (Model 5,1; INTEL Core 2 Duo 2.4GHz), it worked like a charm.
Has anybody seen this behaviour? I'm assuming that it's a software issue (since the GT120 DVI adaptor works with the Cinema HD Display, so the mDVI adaptor should be good). [I also rebooted and wiped the PRAM and NVRAM, to no avail.]
Any and all help would be appreciated.
Best,
Drew

Thanks for the reply--I've done that before, for sure.
An odd thing did happen when I reset the PRAM & NVRAM a second time--it worked. Maybe I did it wrong the first time? Anyway, it's working perfectly now. Many thanks.
