Screen turns black during use

Ok I had this problem before, took it to Apple..They fixed it. Now my computer it doing this again! I had a couple windows open, then all of a sudden my screen turns black. The keyboard light was still on though. So I think the computer may have gone into sleep mode?! Can someone comment on this? Then I pressed the power button to shut the computer off. I tried to restart it. I got to the login page, typed my password. Everything looked fine. Then I tried opening safari and the computer screen turned black again.

"Ok I had this problem before, took it to Apple..They fixed it. Now my computer it doing this again!"
Take MBP back to the repair shop & tell them it's still "broke." If the original repairs were done under warranty, I would call Apple Care first so that they can research your +original repair case number.+
Have you checked your Energy Saver settings?

Screen turns black while using safari

While in safari, the screen turns black & returns you back to home. Appears to only happen on larger sites with lots of data. Getting worst now. Almost happens everytime we're in safari(WIFI). All other apps work fine. I have an Ipad (1). Cleared history & did latest update. Still a BIG problem. Any other advise. Please advise.

If you have cleared the history, cookies and data, you have pretty much done all that you can. Other users are reporting this same "crashing" behavior with Safari.
The only other thing that I can think of that MAY be of some help is to quit apps that are running the background. Few apps really do run in the background, but it doesn't hurt to try this and see if it does any good.
To close apps - Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus (-) sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Some have suggested that if you are using iCloud - try turning off Bookmark syncing and that has helped somewhat.
Apple has announced an update to the iOS that is supposed to be released soon, hopefully they will address this issue in the update.

Does the screen turn black during an Apple Hardware Test?

My iMac screen has started turning black randomly. I searched the forums for advice about what to do an have tried
1. Unplugging everything and rebooting after waiting a while.
2. Resetting PRam (3 times.)
3. Running AHT.
The last test is running at the moment and I set it to Extended mode having noted that the test would probably take over an hour to complete. After five minutes the screen went black and I'm wondering how to tell when the test is complete and if this is normal procedure or a result of the original problem.
I know that the test is still running because I just heard a fan briefly surge, but pressing the keyboard or clicking the mouse does not wake the display.
Will I get some audible indication when the test is done, and if not how should I proceed since the only way to shut the computer down seems to be to hold the Power button for an extended time, or to pull the plug. If I have to resort to these options is there a way to view whatever results the AHT test determined?
Thanks for any help.

Thanks for responding. Could you say whether or not I can expect a notification of the end of the test. I had to shut down the computer using the power button because the screen remained black 90 minutes after the test started. I couldn't see any results for the test I did.
If this pattern continues would you try reinstalling the OS before sending it off for repair?

Sections of screen turn black after using LogMeIn

We had a customer call in yesterday and we used LogMeIn to help her out with her email. Today she called in again and we used LogMeIn again, but this time as soon as we connected some areas turned black. After the connection ended and she rebooted, there are still black areas.
http://i7.photobucket.com/albums/y297/mstrswrd06/blackareas-1.png
(The exception is the parts bloched out with mosaics)
I can't figure out how to fix this. If it was Linux then I would try resetting the X Server settings or go through the window manager settings or reinstall the proprietary driver if one is used. But this is a Mac, so I don't know. Any suggestions?

Not to solve your issue directly, but have you considered using ScreenSharing? It's built it and works quite well.

Screen turns black during video call on Xperia Z

Me too....i am using xperia z....any update on this matter.

alexrx - I was not sure what the test is supposed to do.When I clicked on the Proximity Test in the meny I got a black screen that said "Proximity switch ON". It did not change if moving the phone around.
I did not know where the proximity sensor was located - but a little google helped me along. For others who might find this post - it is located in the upper left corner. Having a screen protector covering the sensor I decided to remove that and it seems to work now. So a dirty screen protector seems to have been the root cause of the issue.
Thank you for pointing me in the right direction :-D (I wish the guy at the Sony support chat had been able to do the same...)

You need to plug the iPad into your computer that has iTunes installed on it, and activate it.

Im using my Ipad 2 and sometimes when I try to look a photo on facebook te screen turns black

Hey !
I was using my Ipad normally when I tried to look some photos on facebook and suddenly the screen turns black, but everything else works good, i just need to press "back button " and I can turn to Facebook and the screen looks normal.
I would really appreaciate if you can help me.

The ! turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
What version of iPhoto? Assuming 09 or later...
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

(Mountain Lion) suddenly the screen turns black, and I have to use the switch to turn it on. And, the screen turns to zoom, and the only way to turn to normal is to close the window and start all over again?

Does the screen go black while you are using the machine? ...or after it has sat idle for a bit?
If it happens while you're using the machine, check to see if a hot corner has been set for sleep. You can do that here: System Preferences > Desktop & Screen Saver > Screen Saver and click the button labelled "Hot Corners..." in the lower right.
If it happens after a bit of idle time, that's normal sleep behavior. The delay can be adjusyed here: System Preferences > Energy Saver.
In either case, pressing any key on the keyboard should bring it out of sleep.
Re zooming -
If this happens while in Safari, and you are using an Apple Magic Mouse, a default setting applicable to it is that a soft double-tap on the mouse will zoom the Safari window. A second double-tap will bring it back.
If it is the entire screen that is zooming, Control plus scroll gesture on the mouse will zoom the whole screen. Repeat with the opposite scroll gesture to bring it back.

Hi, my photoshop screen turns black as i try to use the transform tool

hi, my photoshop screen turns black as i try to use the transform tool

Welcome to the forum.
Can you please provide us with the version of Ps, and also your OS's version?
When the GUI goes black, or begins acting wonky, the first course of action is usually to trash the Preferences.
The second is to check the version of the video driver, from the nVidia, or AMD/ATI Web site, and download, then install the latest for you model of video card, for your OS version.
Good luck,
Hunt

Screen turns black after loading services

Hi
After an update with pacman, then screen of my laptop turns black during boot. At first the screen is working, showing the services that are loaded. Then it turns black. In a flash it shows the messages again, but then it stays black. This happens both in the multi-user.target and in the graphical.target.
I tried:
1) Downgrade the nouvaux driver
2) Full system update
3) Switch from nouvaux to nvida driver
4) Uninstall gdm
But this did not help.
The graphics card is a nvidia GT 650
Below are the folowing log files:
1) pacman.log
What could I try to get the screen working?
Cheers,
Sjoerd

Screen Goes Black During Startup (after login)

Hello,
I have a 2005 Mac Mini PPC OS 10.4.11. This is the first problem I've had since purchasing the computer. This problem popped up out of nowhere. The screen goes black during startup just after I login into my account. I can hear the hard drive spin like it is finishing the startup process. The monitor power button blinks green.
I'm using the digital video cable. I tried switching to the VGA cable but the screen then goes black before the login screen.
The computer will startup in Safe mode.
I've tried Disk Utility (repair disk and repair permissions), Techtool Pro, Drive Genius, ColorSync Utility, Reset Pram, installed latest OS updates, and even re-installed the System twice (once because I removed all the Extension files and then the computer would not startup at all).
I've also tried removing cache files, plist files, startup files, preference files, and some or all of extension files.
The only applications I have recently installed were QuickTime Pro and a .flv movie player; both about a week before this problem started. I tried to uninstall them but could not figure out how.
What is the problem? How can this be fixed?
Thanks.

Howdy. I have Had the same problem as you in regards to a ViewSonic Monitor and the Mac Mini. This is my post:
Monitor failure when switching resolutions
Using Displays with the Mac mini, Apr 1, 2008, Replies: 2
Running 10.5.2 on Mac Mini G4 1.42 Ghz with ATI Radeon 9200, 32 MB VRAM and ViewSonic VX922
When switching resolutions from 1280x1024 to 800x600 or vice versa, the monitor will cut to black and the power light on the monitor switches from solid green to flashing green. Only by combinations of powering down the mini and starting it up again with the monitor on or off will bring the monitor back to life. This problem makes it difficult to play World of Warcraft amongst other games. Any feedback in regards to this problem would be appreciated.
Thank You!
At this point, I am unable to switch Monitor resolutions. If I do, the monitor goes black, and I have to power everything down and wait a while before I can restart.
I've resigned myself to not switching resolutions, but I'm wondering if you've had any luck.
Thanks for your time!

Screen turns black suddenly, then re-emerges within a second

Hi,
here's a new strange issue with my new Asus Eee PC: Recently, and perhaps it's because some updated packages, the screen turns black totally without warning, and shows up again as if nothing has happened. That is, no matter what I currently do, at any time the screen turns completely black (not even dark or something like that) for just a second, and appears again simply. Nothing strange can be noticed, my session just continues as if this didn't happen.
I haven't had any success finding the triggers for that behaviour, it seems so accidentally ... be it browsing the web, right after session startup and everything else. What I've noticed though is that it happens only a single time within a session and both on battery and on power.
Graphic chip is an Intel Mobile 945 GME, and I'll add my xorg.conf as soon as I can. Strangely, there is no note in Xorg.0.log either.
What I'm currently doing now is checking whether this also happens in a GNOME session. Sounds strange, but the first time I've noticed this behaviour is with Openbox, and the last days I was using only Openbox. Still I don't know whether Openbox might cause this problem.
I'd be very glad if someone could give me some hints on tracking down this issue. Perhaps this also happens at someone else's machine.
Gratefully,
Leye

Good to know that there are other people with the same issue as well. As long as I use Openbox, I've deactivated gnome-power-manager, though I hope this will go away with new updates. In the meantime, deactivating gnome-power-manager is o.k.
I don't know though what you should do if you rely on the whole GNOME desktop.

T400 Screen turns Black/Gray and System Freezes.

My screen turns black or gray and the system freezes.
The only way to fix it is to restart the system by opening all forms of power supply (adaptor and the battery).
Sometimes it works fine for a day or two, sometimes only for a few hours.
I think the problem has something do with my graphics drivers or some other driver from Lenovo.
I have used Lenovo Thinkvantage Toolbox to check for hardware errors and it shows that everything is working fine.
I have updated all drivers but still the problem is there.
I still have warrenty period left.
I bought my system 2 years ago and have never had any problem untill this one.
My system specifications are given below.
Model: Lenovo Thinkpad T400 2764 CTO
BIOS version (Latest?): 3.18 (latest)
OS loaded (ex. Win 7 64bit): Microsoft Windows 7 Ultimate 64-bit
Lenovo default OS: Microsoft Windows Vista Basic 32-bit
Updates from TVSU completed? Yes.
Updates from Windows Update? Yes.
Power Manager Version: 3.25
RAM installed (brand and 1 x 4gb, 1 x 2gb, 2 x 2gb?) 2 x 2 GB
Model of discrete card: ATI Mobility Radeon 3400
Any error notification? No
3rd party application installed for the graphic card? No.
Any particular application which is running on the time this issue arises? No.
Running on battery? AC? Docked on station? Error occurs in any state.
Any solutions?
Anyone had similar problems?
Thanks.

My problem seems to be similar. Sometimes my screen also turns black unexpectedly and the notebook freezes completely! In some cases I see a bluescreen of death and in some very few cases it restarts automatically. If it does not restart automatically I have to hold down the power button for some seconds to turn the notebook completely off (so that the "power on led" left to the "battery led" is not illuminated any more). Thereafter it is possible to start the notebook again. So unlike user 400 I do not have to remove any connected power sources.
The issue seems to occur out of nowere and seems not to be related to the use of a specific software. My system is up to date with lenovo drivers and windows update, exept the BIOS, which I updated the system two times since the problem exists since more than half a year!!
I also give my system specifications below:
Model: Lenovo Thinkpad T400 2767 WC8
BIOS version: 3.16
OS: Windows 7 Professional x64
Updates from TVSU completed? Yes. (exept newest BIOS)
Updates from Windows Update? Yes.
Power Manager Version: 3.25
RAM installed 2 x 2 GB (bought and placed by loenovo reseller)
Model of discrete card and integrated card: ATI Mobility Radeon 3400 and intel mobility 4 chip
Any error notification? yes, entry for bsod or kernel-power-issue in the system protocol (but no specific error)
3rd party application installed for the graphic card? No.
Any particular application which is running on the time this issue arises? No.
I use my notebook with AC connected, with battery and most of the time in the advanced mini dock! Since a few days the error never happened when the notebook was docked! So I thought it is a power issue or has something to do with the graphics card.
But now I found out, that the issue might be related to the wlan card! This is because I never had a wireless lan connection when the notebook was docked, since I use a LAN cable. But a few days before I had to use the wlan while my notebook was docked and the error occured after some time. Furthermore, as far as I remember the issue never occured when the wireless lan was switched off and not docked, but I will check that again.
The issue also never occured when I booted windows in safe mode.
@400
Maybe you can check if it is the same for you with your wlan? Maybe together we can find out what the exact problem is. I want to find out what is the problem to get it fixed by lenovo. Until now they alwas said, that they had never experienced such an error.
Please keep on reporting.
Thanks for any help
