Display black

My laptop display has gone black and I cannot find any means of getting it turned back on. This problem has occurred intermittently in the past and I have been able to get it back on by closing the laptop and then reopening it and all is well.
I was using the laptop in a VERY bright room where it was difficult to see and hit the display brightness key to see if that helped; all went black and nothing I have done seems able to help.
Any ideas or suggestions, please?
Thank you.

Your are close--don't give up yet!
You can access the Displays part of System Profiler by doing control-click with the cursor anywhere in the Finder; you get a contextual menu--one choice is "Change Desktop Background." Once that opens, you can click "Show all" at the top to get back to the main SP screen to select "Displays."
Sounds like you are in video mirrored mode. Hit the F7 key to toggle between mirrored and extended mode. This should automatically make the external usable. When in extended mode, System Preferences > Displays gets an extra tab--"Arrangement"--that lets you customize the monitors. You simply drag the representation of the menubar in the SP window to the representation of the monitor you wish to be the main one. Although the internal doesn't work, the system will probably think it's there and give you the proper options
My 17" PBG4 is currently connected to an older 4:3 aspect ratio NEC 19" CRT but I have it in extended mode and both monitors have proper desktops. The NEC has the menubar and the built-in has some palettes and Stickies I need but don't want on the main screen.

  • 27 inch thunderbolt display blacks out after Thunderbolt Firmware Update 1.2

    Bought 2 new 27 inch TB displays for two different machines and after a couple of days the Thunderbolt Firmware Update 1.2 appears on my Mac Pro with one of the displays installed. So I install the firmware update.  Now my display blacks out periodically and I keep getting Graphic Display Errors with a request to sent the errors to Apple. Running a 32 GB Mac Pro (late 2013 circular style) I have three monitors connected (two 20 inch cinema displays and the new 27 inch display). This machine is supposed to be able to handle three 4k monitors or 6 standard TB displays.  I've seen the posts about the blacking out with this monitor but I didn't have any problems before the firmware update and now I've got them pretty regularly.  I had the blacking out problem on an earlier monitor and took one of the monitors back and Apple gave me another one and this is the replacement.  Same problem, but this one only started after the update. I'm hoping someone from Apple reads these messages and can let me know what's up.
    BTW, I also have an older 27 inch Apple monitor that ran perfectly on this machine so I'm disappointed that I spent all this money and now get the blacking out issue.

    I have my Thunderbolt display connected to my MacBook Pro and have been experiencing the same issue, getting worse over time.  The folks at my local Apple store did not know what to do about it.  So, I looked around and tried different thing.
    The one thing that seems to be working is to System Preferences > Build-in Display > uncheck “Automatically adjust brightness.”
    I hope this helps.

  • Adobe Photoshop CC + Lightroom CC are displaying blacks with a green tone.

    We did a monitor calibration a couple days ago with an EyeOne, same we have used many times and all went well. But now we have noticed that Photoshop and Lightroom are displaying blacks with a green tone over them. If the image is saved and viewed in it's folder it looks fine. All the settings in both programs are fine, both set to sRGB to match our camera profiles. It seems as though they are actually correct, just displaying wrong on the monitor. Has anyone else had this problem and know what we can do to correct it? Thank you

    i cant believe this problem is still happening. same exact issue here. photoshop cs6 and CC run like **** on my macbook but run smooth on windows 7 on the same exact hardware, macbook pro 2.5ghz core i5, 16gb ram and intel hd 4000. ive talked with applecare about this, adobe support (who hasn't called me back twice now) and no response on how to fix this. its absolutely ridiculous that we are having to go through this much trouble to get this problem fixed. ive brought it up over 5 times now and no solution except for the usual suggestions (turn off hardware acceleration, delete your preferences, yada yada). same hardware, mac osx photoshop cc lags, windows photoshop runs fine.. something is wrong with the mac version of photoshop cs6 and CC adobe please fix this as soon as possible.

  • Why does slideshow created in Elements v12 display black

    A slideshow created in PSE v11 plays back correctly on my Windows 8 computer, but running a slideshow in PSE v12 on the same computer in the same session displays the slides as black. There was a suggestion that the photos are at too high a resolution to playback, but I am using the same photos. I even created a slideshow with only three images that were about 1 meg in size each -- same problem.  There is no error message and the audio does play.
    I imported into the Organizer (PSE 12) three different video formats: wmv, mp4, and m2ts. All three played correctly. It is the slideshow created with PSE that displays black.  What needs to be updated? What steps can I do to correct the problem?

    I think the difficulty is that because it doesn't affect everyone they can't recreate it and so can't fix it*. If you want to report it the place to report bugs is at http://feedback.photoshop.com (this is a user-to-user forum so Adobe won't see it).
    * Mind you with a release cycle of only twelve months it's very rare to see any updates other than to Camera RAW.

  • Display blacks out

    so on my ibook g4 mid way through using it the screen blacks out (there is a very faint glow) this is happening more regularly now and atm as a temporary fix i just close the lip and open it.
    iv looked through some forums and it seems like a problem that i cant fix myself...
    but i was wondering can i just connect the laptop to an old display i have? or that display black out as well.
    any help would be great, thanks.

    Welcome to Apple Discussions!
    When the display blacks out, can you shine a flashlight through the back and still see your desktop? If so, you likely have a problem with the back light or inverter or possibly a cable, which will affect the built in display. Since you can see your display at times, I imagine that the graphics chip itself is still working OK.
    Is your old display an external display? If so, it should work.
    Good luck!

  • DISPLAY Blacks out sometimes

    Most of the time when I sit back down at the computer desk my display black out for a second. The light turns of, but it comes right back on. Someties it does it several times before it stops. I know thta there is alot of static in my apartment. Does anybody know anything about this? If so, is there anything I can do to prevent this?. It is pretty annoying. Any help would be appreciated.
    Oh yea, the display is a Starlogic

    I have a Mac Pro, and a Mac Mini. I have owned tha Mac Mini for about two years. I have found the same issue with my mac mini. I do believe that it is normal, and it has something to do with the shared memory. I ran it for over a year as my main Mac, and I experienced the very same thing. I don't think it is anything to worry about, unless it happens over and over. My Mac Pro does it form time to time, although very very rare. It also could have something to do with the display, analog vs digital etc. I believe the digital signal experiences very short interrupts every so often, and that in my experience is normal

    There is no Apple here, this is a user to user forum.  When you said you restored, then you restore as NEW?
    If you restored as New and still the problem persiist, then it time to take a trip to the Apple store.

  • Image displays Black

    I have an image that displays black on the slide in my Captivate 4 project when it is published. I have attached both the slide and the image properties.

    Hi again
    Methinks it's time to save the image as a different format. Perhaps .GIF, .JPG or .BMP.
    Once in a blue moon I have an issue with PNG format. But by and large they simply work. Note that some applications use .PNG as their native format. Adobe Fireworks is one example. And in Fireworks you may use different layers like in Photochop. Sometimes the additional data isn't easily understood by other applications such as Captivate. I know Adobe RoboHelp HTML has similar issues with PNG format.

  • HT5219 Apple thunderbolt display blacks out and blinks

    Hi,
       I have a macbook pro (2.5GHz Intel core i7, 16GB RAM and 10.8.5) for which I use Apple Thunderbolt display as my extended monitor and almost everyday after connecting my external monitor for 3 or 4 hours, Apple thunderbolt display blacks out and starts blinking or displaying weird colors on every blink.
    To stop it from doing that, I have to disconnect and reconnect my thunderbolt display.
    Is this is universal problem or something wrong with my macbook pro ?

    I've got two 27" Thunderbolt displays hooked up to my Mac Pro. Both displays blank out irregularly multiple times per hour.
    I've exchanged one of the displays for a brand new display and the problem continues.
    I've updated both displays using the firmware update a few months back and the problem continues.
    I'm using separate Thunderbolt cables rather than the built-in cables and the problem continues.
    Bullocks.

  • Early 08 Mac Pro display black on start up!

    Hi
    I have an early 2008 Mac Pro with what looks like a faulty ATI Radeon HD 2600 XT.
    There has been a longstanding issue with my 30" Cinema Display going blank (black) during a restart. It happens about halfway through startup when the spinning wheel is on screen. The white LED on the display lights solidly. The Mac appears to boot up normally and I can shut it down blindly using key commands.
    Occasionally, unplugging the display and then re-plugging it brings it back to life but animation such as Dock magnification then becomes very jerky.
    I've zapped the PRAM, reset the SMC numerous times. Both have occasionally bought the screen back to life but the problem has always re-occured. I've removed the graphics card, cleaned the connectors and then replaced it.
    The issue has remained through a complete reformat and installation of Leopard and then Snow Leopard plus numerous OS updates.
    The Mac almost always starts up normally first thing in the morning. The problem seems to get worse throughout the day, i.e. the longer the Mac has been on, the more likely the graphics are to fail on restart suggesting an overheating issue perhaps?
    I would send the Mac in for repair BUT... it is stuff full of 3x Pro Tools PCIe cards and I REALLY don't want take them out OR send it in with the cards in place. (Please note: the problem was occurring long before the Pro Tools cards were installed.
    So... my question is, does this sound like a faulty ATI Radeon HD 2600 XT? If so, I'll try and get a replacement. (Any idea where in the UK? I've searched everywhere!)

    Your Mac uses a default setting to fire up the display and set a start-up picture. Halfway through the boot-up process, it switches to the stored System Preferences. This file may be damaged. A re-install (keep my preferences) would not fix it.
    I suggest you boot up in safe mode (hold down the shift key all the way through startup) and use System Preferences > Displays
    ... to change something about your display, so that it will re-write the Preferences files.

  • External Display Blacks Out

    I have MacBook Pro 13" (early 2011) hooked up to an external display. With Snow Leopard this setu worked fine. But after upgrading to Lion the external screen constantly blacks out. I've seen some suggestions saying that it might be the adapter but, as I said, this setup worked fine in Snow Leopard so I find it unlikely to be an adapter issue.
    Does anyone have any suggestions on how to fix this problem? It's extremely annoying.

    This has been fixed in one of the latest OS updates.

  • External Displays Black Background

    I work with two external displays and yesterday I unplugged my MBP to go to a meeting. When I returned and plugged my monitors back in both their backgrounds were black. They work fine and I can drag applications into them and be displayed but I can't shift the black backgrounds.
    If I open system preferences it launches fine and if I select Desktop & Screensaver the panes launch in all three monitors and display their current background. If I change the background it changes in the preferences pane but not the actual display. If I mirror all monitors it displays fine on all three. The only inconsistency I've noted is that when adjusting backgrounds the pane on the right hand display adjusts the background in the central (primary) monitor. This right hand display is also the actual laptop with the two external display positioned to the left.
    Obviously not a critical issue but I would love to get to the bottom of it.

    Hi rossmatt06,
    If you are having intermittent issues with the external displays connected to your MacBook Pro, you may find the following article helpful. In particular, if at all possible I would test with different adapters to try to rule out an incompatibility.

  • A new 23" studio display blacks out from time to time

    Just got this great new display. Once a day maybe, the screen goes black for about one second, then pops back up.
    What could be causing this?
    G5, single processor   Mac OS X (10.4.7)  

    One thing to consider, maybe you accidentally move the mouse into the sceensaver hotspot and then once it starts to black out, then you move the mouse to turn off the screen saver and it seems like it blacks out?
