Random screen blackout 2009 24 inch Cinema Display... HELP.

Random screen blackouts with 24 inch Cinema Display (purchased 2009). Never used with anything but same Macbook Pro (2009). No hardware changes on MBP. Just started June 6, 2012. Super annoying. Anyone else having this issue? Recommendations?

Hello, Ertjie.
The link titled Download the 24-inch LED Cinema Display Update from the kb/TS4045 article worked for me when I tried it today. Click the "Download" link I post here or try the one in the kb article again. Perhaps it will work for you now?
However, I note that the kb article expressly states that this firmware update:
...is only intended for use with and will only install on the Apple 24-inch LED Cinema Display while the display is connected to a Thunderbolt-enabled Mac. (EZ Jim emphasis added)
If your Mac is really using Mac OS X (10.6.8) as shown in your initial topic posting, your Mac may not be Thunderbolt-enabled. If so, contact Apple or your Apple-Authorized Service Provider for help.

After iOS 7.0.2 update: Freeze on lock screen, blackout & unresponsive for 5 min then the phone restarts itself

Happened after iOS 7.0.2 update a few times (2x this morning): Freeze on lock screen, "blackout:" unresponsive to any buttons pressing, after 3-5 minutes the phone restarts itself and works again... (1) May I ask what can I do? I am trying to reset it and recovering the data from backup. (2) Can a virus cause this problem?

To rule out a software issue, set it up as new device without using the latest backup.

If it does not charge normally after that, you'll have to get it serviced, the problem might be hardware related.

Screen blackout running Windows 7 in Bootcamp

I've just upgraded to the latest Lion on my iMac 8,1 and the latest version of Bootcamp running Windows 7. Now I get random screen blackouts, which require a complete shutoff of the machine. I suspect it might be related to the new NVIDIA driver. Any thoughts?

I have a similar issue which first occurred today. I was using Windows, and had been logged in for several days, when suddenly a relatively small blue box appeared in an otherwise black screen. I didn't have time to read what appeared in it. I started up in Windows afterward and the start up process seemed normal, i.e., all was visible in the OS and I could enter my password. But, presumably after accepting the password, I only received a black screen. This continued until I used the power button. After briefly pressing the power button, I could see the mouse pointer and a spinning icon and the computer would then shutdown. I hadn't been installing or updating any software in Mac OS or Windows before this incident.

My iphone4S suddenly became totally screen blackout, I try to call it from my other cellular still its ringing how can I open it?

To all concern,
My iphone4S suddenly became totally screen blackout,I try to call it from my other mobile its still ringing at the vibration still working how can I fix it,please help me Apple Communities

Try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose data by resetting.
If this does not work, connect in recovery mode to your computer and restore, explained here:

Unpredictable screen blackout when gaming

After about 4 years of owning my 21.5" intel iMac, I started randomly experiencing screen blackouts while playing mildly graphically-intensive games. These blackouts did not effect the actual computer, but the display flickered a little and then went black, and required a shut down and unplug. While blacked out, pressing the brightness button would make the screen show itself once or twice, but after that it remained off. This usually happens 5-10 minutes into a game, and is extremely annoying. This started happening yesterday and has happened about 10 times now. What can I do to stop this from happening?

Welcome to Apple Support Communities
As you mention your iMac screen was flickering, it may be a GPU issue. The same thing happened to me a few years ago and my iMac started flickering all the time after some days.
I recommend you to make a backup of your files onto an external drive and take the iMac to an Apple Store or reseller to get it checked. Maybe it is not a hardware problem, but it is better to be sure about this.

IMAC 27" random screen blackout

my 8 month old iMAC 27" quad core machine recently started to "black out" Screen goes black for no reason and the only remedy is to hit the power button - usually twice. This will bring the system back to where it was, all open APPs etc. will be exactly where you left them. I also tested the speaker volume up/down keys to see if the "system" was still functioning during a screen black out. THe CPU etc. is still avtive as the speaker volume when maxed out will "beep" at you.
I called tech support - they had me do some special resets of power control and PRAM - no luck
I took the system into Apple store for Genius Bar appointment - 2 hours of running the mac in the store, of course it did not black out....however, they ran other diagnostics and ran a bunch of utilities, graphics etc. to max the RAM and CPU load, heating up the system but still nothing happened. they suggested I reistall the OS by doing a hard boot and holding down the command key to prompt me to re-install the OS from the "cloud". This did not solve the problem either.
I then took the system back to Apple and told them to fix it or replace it. They kept the system for 5 days, and replaced
item 661-5948 Board, Logic, 2.7GHZ, Quad Core i5
item 661-5967 card, video, AMD radeon HD 6770M, 512M
item 661-6615 LCD panel 27 inch with BLC
and labor: TOTAL COST $1183.32
This was all under the first year warranty so I did not have to pay for this out of pocket. If you look at the list of repairs, they effectively gutted my iMAC except for the HDD and enclosure. Ahhhhh at last I thought I would be back to a fully functional iMAC. Two days after getting home and just browsing the internet the blackouts started again.
Once the system blacks out the first time (which appears to be a completely random amount of time) it will then black out more frequently after hitting the power button.
It's time to call Apple again and demand a new system, wondering if the iMAC LCD crystal / video components are suffering from a manufacturing defect....as it seems the new components they replaced are suffering from the same issue.
APPLE - would appreciate you recognizing this problem and working on resolution.
thanks,
Share holder and completely converted MAC power (family) users!!!!

Hi, I hope you find this information useful:
A few years ago, we purchased iMac 27" 11,3 (Mid-2010) (with i7 2.93Ghz, ATI 5750 1GB VidRam, etc.) for our offices and software development team. They were originally shipped with Snow Leopard and worked as expected and without any problems. However, a year later, we upgraded to Lion and all of machines immediately exhibited the same problem: the screen would go to sleep by itself and would require a hard reboot or sleep on/off. (Only the screen was asleep and the rest of the iMac continued to function; this was confirmed by screen sharing to the machine.)
Due to the severity and impact on our business, we immediately contacted Apple and their genius bar staff in New York/SoHo. They were unable to determine the root cause, so they replaced all of the logic boards, video cards, and screens, and got us back online asap. This resolved the problem, but we were curious to know why. After days of rigorous testing, we concluded that the issue is caused by a bug in MacOS. Specifically, faulty Kext files (Kernel Extension files extend the functionality of the MacOS Kernel) for the ATI drivers. So, why did the replacing the hardware work? We think that the Kext files that were released and distributed with Lion (and later MacOS versions) correctly supported the newer hardware revision of the replacement components, but not the older ones.
If you're experiencing this problem, short of replacing the components or waiting (for another 3+ years) for Apple to hopefully fix their OS software, you can lessen the effects and be able to recover faster by doing the following: (Please bear in mind that these are not permanent fixes.)
Turn on "Hot Corners" and assign one corner to "Put Display To Sleep". When your screen goes to sleep, move your mouse (which still works) to that assigned screen corner for a second, then move it again. This will wake your screen. You may have to do this a couple of times, but it's much faster than a hard reboot or a sleep on/off for your iMac.
Turn the brightness of your screen to a low setting (10%-15% of the total brightness).
Turn on screen sharing, so you have a last resort method of accessing the machine.
If you're not convinced that it's a MacOS software problem, then do what we did and see for yourself; install Windows 7, Windows 8, or Linux via Bootcamp or as the only OS on the iMac. Those operating systems and drivers worked flawlessly for us; the bug does not occur and the screen does not go to sleep, but if you dual boot and switch back to MacOS, the bug reappears because the iMac is loading faulty Apple MacOS software.
Good luck!

How to on my screen blackout on iPhone 4s

My iphone 4s screen is blackout and on voice command at the same time

Hello, luv_rossy.
Thank you for visiting Apple Support Communities.
This sounds like screen curtain may be enabled. Screen curtain is a feature that allows display privacy. To disable screen curtain while VoiceOver is enabled, you can three finger triple tap the screen to disable this feature. You may need to press the home button once in order to process these steps. If you wish to disable VoiceOver, see the link in the article below.

Iphone Screen blackout

IPhone 3GS
IOS5
the Phone is blackout but still receiving calls.
reboot with 'power'+'home' buttons, the screen displays icons but very dark and can hardly see it. I checked brightness: auto mode is on.
Any help is much appreciated.

In order to fix KERNAL PANIC... force the iPhone handset into DFU mode (recovery mode)...
1. Force device shutdown.... by holding the power and home button.
2. Now hold down the home button for 10 seconds and then still holding the home button connect the iphone to the computer, release home when you see the itunes symbol or after around 10 further seconds.
3. At this stage you can connect it to iTunes and then do a factory restore.

Macbook-Screen Blackouts

I have a Macbook and I have had it new since this past Christmas. Every once in a while the screen will go black for a few seconds and I just have to wait for it to restore itself. I haven't found a pattern that causes it; sometimes I'm online, sometimes off, it can be hours after waking from sleep or sometimes it happens just after I've entered my password and hit enter. I'll see my desktop briefly then there's a blackout and it takes me back to re-enter my password and unlock it from screensaver. Is there a fix for this?

Either the inverter is flaky or else the connection between the inverter and the backlight lamps is intermittent. Either way it is a hardware problem and will have to be returned to Apple for repair. If you still have a warranty, the repair will be free of charge.

Macbook 13 inch mid 2009 Screen Blackout

The screen on my 13" macbook keeps going black. It will come back sometimes if I adjust the screen position or decrease and then increase the screen brightness. These fixes are not lasting long enough anymore. I unplugged the inverter and plugged it back in as suggested, but the problem remains. How do I confirm if where the problem lies? Is it the inverter, the inverter cable, or the backlight??

Hello alicia_mari and welcome to Apple Support Communities,
" It will come back sometimes if I adjust the screen position"
Now that's the symptom of a bad backlight cable.
" or decrease and then increase the screen brightness."
I have a MacBook with exactly the same problem. Run the brightness all the way to zero and back one step and it would run like that for a long time. Increase the brightness and it would go black. I swapped out the logic board, inverter board and the problem followed the display so I'm assuming bad backlight.

Equium A60 screen blackout but an image is still visible

Purchased this laptop as it was supposed to be reliable. After 18 VERY basic use the screen started to black intermittently until 3 months ago it failed completely; I now use an external flat screen(had that for 4 years! no problem).
Now I have noticed there is still an image visible on the A60 screen. I have been told that the backlight may need replacement or I read that possibly the FL Inverter? needs replacing.
Can anyone suggest how I overcome this problem especially as I am told a replacement screen might be as much as a new laptop. PS One of the keys also failed-never happened before on any keyboard since using computers when they first came out.
Any help welcome. davee

Yes, you suggestion is not bad. It could be really an FL inverter fault. This little part is not very expensive and can be responsible for your problem.
But I think you shouldnt replace this part yourself. I think you have no much experience in such replacement and therefore you should ask the technician for the help.

Qosmio G20-127: Screen blackout after closing the lid on Vista

Hi,
I have Qosmio G20-127 and I've recently installed Vista Ultimate Edition (32-bit). I managed to bring everything to its place (except the magic buttons, but the drivers are not out yet), but I have a problem that is seriously making me reconsider going back to XP MCE.
When I close the lid of my computer the display naturally goes off, but when I open it up again it does not turn on, but it stays black. And I can't make it turn on again no matter what. I have to turn off the entire computer and that is quite impractical.
Funny thing is that after restart for about 20-30 minutes I can open and close the lid normally, but after a little longer work on the computer the same problem occurs.
The problem persists even after I turned off every action remotely connected to closing the lid.
Does anyone have any solution?

Hi J,
thanks for your help but my BIOS update won't install. I get the message "[Error] BIOS Update is not supported OS. Unsupported OS or service pack is installed."
About the powersaver, I didn't install additional powersaver program as I was told it would conflict with Vista's Mobility Center (FranciscoJr's Guide to installing Vista), but all the options regarding closing lid are turned off (Do nothing option).
There are two more new things I observed and might be indicative of the problem, but I don't know what to make of it.
1. When I close the lid I hear 'disconnected device sound'
2. And the screen sometimes comes back if the s-video cable (leading to my tv) is plugged out (usually it was always in coz I use Q20 as a media center as well)
Of course that made me think that it might be a problem in Graphic Card, but I've installed the most recent driver.
So now I'm pretty much clueless as what to do.

How to squash a nasty screen blackout bug

Hi Mac experts,
I've been trying, without success, to squash a nasty Mac bug that causes my screen to black out during work or causes it to never wake up after sleep, the latter being more frequent. It's supremely annoying since it interrupts work a couple of times a week and, embarrassingly, happens more often during public presentations, possibly due to the 2nd screen. In some cases a single hard reset revives the MacBook, in others I have to reset several times for the screen to become accessible again. When the bug happens, the OS is still running (key feedback sound, keyboard backlighting can be adjusted) but the screen is completely black.
It's been an unfixed bug through several OS versions from 10.8, 10.9, to the latest 10.10 (Yosemite). The usual remedies suggested in forums did not work (see below). I'm out of ideas here, hopefully you are not.
My specs: MacBook Pro Retina 15'', purchased 2012.
My recent crash reports can be viewed here: https://drive.google.com/folderview?id=0B_EEMeI_SbKxMlZSVHhXdm1QZWs&usp=sharing
I have tried the following:
udpates did nothing; crashes under all OSs (10.8, 10.9, 10.10)
reinstalled 10.9 fresh and migrated my data; still bugged
startup in Safe mode (disables kernel extensions); crash on the same day
adjusting the energy prefs (disable switching, deactive all additional wake up conditions); did nothing
SMC and NVRAM resets did nothing
This is a bug shared by many users. Apple obviously is not fixing it. One user reported that in his specific case it wasn't a hardware issue. Replacing the motherboard did nothing (http://bit.ly/1E5cEAR). Here are some related reports: forums.macrumors.com/showthread.php?t=1722832 (2014-4; solution: detaching from ext. screen before sleep), discussions.apple.com/thread/6014780?start=0&tstart=0 (2014-03; not resolved), discussions.apple.com/thread/5665501 (2013-12, not resolved), discussions.apple.com/thread/5548226 (2013-11 to 2014, not resolved), forums.macrumors.com/showthread.php?t=1553654 (2013-03; solution: removal of Bresink driver), bit.ly/1wdVO1C (2012-8, problem w Bluetooth, fixed by OS update 10.8.1),..
I hope somebody has a suggestion. Looking forward to your expert insights.
All the best
