Screen blacks out during install of 10.6

Just installed Snow on a Mac Mini and a first gen Intel MacBook Pro. In both cases I lost the video part way through. On the Mac Mini I had to do a restart and the install picked up where it left off. The MacBook Pro had a screen image but no monitor back light, so I had to use a flashlight to go through the install process again in order to see the cursor and screen instructions because I interrupted the install with a power button restart. If you experience a black screen but can just barely make out something on the screen, DO NOT panic and decide to restart. Get a bright light on the screen and you should be able to see the progress bar after you wake up the screen dimming. Before you install set your screen dimming to never. Hope this helps.

It happened this morning again. Attached a picture I took of my MacBook when it went dark. I have to close the lid to sleep and wake up again to regain brightness.

Mac Mini 2011 screen blacks out during heavy screen activity

I have a Mac Mini 2011 i5 2.3Ghz with Intel HD video. It's connected to a 30" LCD 2560x1600 (Dell WFP3008) via mini-DP to DP cable and a 22" LCD 1920x1080 (Samsung LCD TV) via HDMI to HDMI cable.
For the first few weeks I had it connected to the 30" only and it was fine. Then I hooked up the Samsung as a second display and the problems started.
The problem is that the Dell blacks out briefly, then comes back. It is not "drawing" the screen black, the signal to the Dell gets disrupted momentarily so the monitor has no signal so it goes black. Then it resyncs with the signal and the display is back. This only happens to the Dell, during the disruption, the Samsung image stays put. I know it is a signal disruption because the Dell shows a displayport icon showing that it has just resynced to that input.
The problem happens more frequently when more things are going on; like if I have a window or multiple windows playing video, then the disruption happens more. If I disconnect the Samsung, it happens less. It could even happen if a web browser window taking up a large portion of the 30" screen does a full page update, it will disrupt. If I am running Adobe Lightroom, it seems to happen more also.
When it happens it seems like messages like this appear in the console, although i can't say they are directly correlated:
6/1/12 8:28:46.000 PM kernel: IOSurface: buffer allocation size is zero
I'm thinking perhaps the mini is running low on memory since the 2560x1600 is pretty high res and then add the 1080p screen and stuff being updated, perhaps it runs out of memory and disrupts the signal while it garbage collects? Pure speculation.
Has anybody else seen this and have any clues on how to resolve it? Thanks.

I should clarify that when I say perhaps the mini is running low on memory, I mean low on shared video memory, since the computer has 16GB installed. I'm not sure how to view or test shared video memory allocation.

My imac's screen blacks out during booting

MY imac froze and restarted recently, then when i got into the computer it froze and shutoff again. This time when i tried to turn it does one of a few things... 1 it only gets to the Apple logo then blacks out, 2 it goes to the place i requested by key commands, or 3 it has the Apple logo, then a loading bar that only loads for about a second and only reaches a very very small fraction of full capacity, then lastly goes to a spinning loading wheel that lasts 5 seconds at most then it blacks out once again.

We do not know which iMac or what OS X your on, but that sounds like a hardware problem.
Run the Apple Hardware Test, as per > Using Apple Hardware Test and report the results either here or to your local Authorized Service Provider.

Screens Blacks out during Remote Desktop

I have a 2008 iMac running Yosemite (up to date) with a boot camp partition with Windows 7 (fully updated). Running in Windows 7, I start Internet Explorer 11 and go to my company's remoting website and initiate a remote desktop connection. While there everything works great but at random intervals from a few minutes to about 40 minutes the screen suddenly goes black and I cannot get it to be visible again. I end up having to power down the computer by pressing the power button for about 12 seconds and restarting.
In ONE case, I left it running in Windows 7 overnight and it was black by the next morning, though in that case I was trying to power the computer down, but instead of powering down, the screen brightened up.
This is VERY irritating. I have tried turning off Windows 7's screen saver which had no effect. I have also tried minimizing the remote desktop connection and moving around some windows thinking the original non remote window might be timing out somehow, but again no effect.
Anyone have an idea of what I could try. Note that in OSX, I NEVER see a problem. When running in Windows XP in Parallels, I also never see that problem. On my other computer (MacBook Air) I have a parallels Windows 7 virtual machine and I don't see the problem there either.
Thanks.

My screen blacks out during phone use.

Wondering if anyone else has had this issue ...yet.
Started on Friday 1/20 while watching a you tube video, thought it was going through a random reboot.
Screen barely powered on while trying to fix then randomly starts back up.
Happened again Saturday while on Facebook. Did a battery pull.
Then again Sunday using Facebook, once again.
Just curious though... anyone else?
Also, if I have to take it back to the store for the issue that should be covered by factory warranty are they good with in store switch of a new phone?
I used to get those when I had my En-V2
Don't know if smartphones have different ways...
Thanks

Limelemoneez, thank you for sharing your concerns with your device. I have not seen this issue with the Nexus so far. Since this seems to happen mostly when using the Browser and web applications, have you tried clearing cache from your Browser? If not, try this first. Open your Browser, press the 3 dots to go to Settings, choose Privacy & Security, clear cache. If you have installed any antivirus applications, please uninstall those. Also, if you notice this started after installing a new application, please uninstall that app also.
If this issue is still occurring, then I suggest completing a factory reset. This will erase all data from the device and reset to factory default settings. Since this phone does not have an SD card, I would recommend connecting to your computer to backup personal info like pictures, videos, etc. Also, check your Gmail account to make sure pictures backed up.

Screen Blanking Out During Phone Calls - Solution

Previously I noticed many posters complaining about a problem with their iPhone screen blacking out during phone calls. I think I may have found the solution, or at least a solution. I have been advised by the Apple Store technicians that the case I use (and indeed, many cases that are sold in the Apple Store), are so opaque that they block the sensor found near the earpiece. This is the sensor that tells the iPhone screen to black out when it is next to your ear, and to light up when it is away from your ear. Because it cannot sense through the case, it still thinks it is next to your ear and hence keeps the screen blacked out. And sure enough, when I took my iPhone out of the case, the problem disappeared.
Now here is the question - has anyone got experience with a good case that does not cause the above problem? And those who do have a problem case - have you been able to return or exchange it with the manufacturer?

You have this product - which is specifically designed for the iPhone 3G?
http://www.iskin.com/revo2_features.html
This is the case I've used with my iPhone 3G for the last 6 months or so with no problem.
There is an iSkin Revo for the first generation iPhone, which is not designed for the iPhone 3G since the proximity sensor and light sensor with the iPhone 3G are in a different location than the location for these sensors with the first generation iPhone.

Screen blacks out after latest itunes update installed

last year after installing an update for itunes my screen blacked out. it then intermittently worked for a few days before failing permanently. this was later fixed by replacing the inverter board. i didn't suspect the two events were linked. however, yesterday i got the latest update for itunes and again a few minutes after installation my screen blacked out! deja vu... it seems unlikely but is it possible the screen fault is caused by updating itunes?
this morning the screen is working again and i have run system restore to undo the installation. fine, but when i try to open itunes it starts installing again.

Thats odd. Not sure what this error means, but you could always try repairing disk permissions, that seems to solve most of the random errors that occasionally pop up on my OS X macs. Load the OS X install dvd into the drive then restart your machine holding the C key. choose english as the main language. Then go into the utilities menu and select disk utility. Click on your hard disk then click the repair permissions button. Once completed, restart the computer into OS X. Then try your screensaver again. If this doesnt work, post again and I'll take a closer look at it.

Since installing yosemite my computer/screen blacks out, but still running

Since installing yosemite last week, my computer/screen blacks out, but still running. I have since rebooted everything, started from scratch and utilizing my external drive transferred all files/apps back. Did not help, in fact it is getting worse. Computer screen blacks out every 5 min or so and have to power up again. Also, continue to get Java message updates even after all have been updated over and over again. Any suggestions? Thanks!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Random laptop screen Black out / Turn off .

Hi,
first of all my laptop is : HP Pavilion dv6-6160se Entertainment Notebook
to the problem now
A few days ago my laptops screen started out of a sudden shutting down/turning black( no lights at all ). This was happening while using the laptop at random. The screen had no lights, and if i use a flashlight on it there is nothing. like its turned off completelly.
Before this happens. Ths behavior varies. Sometimes it flickers from my desktop to a black screen then back on and some times not. Most of the times screen changed to a radom color (green mostly) then becomes black/shuts down.
NOTE: The laptop keeps runing, i can hear the videos playing so it probably isnt a gpu chip or gpu issue , music and games.
I searched the web for all kind of reasons that this could happen and tried some of the fixes .
Here are everything i tried and all or the details i could accumulate in past coupe of days:
1. If the screen flickers , blacks out and then turns back on i get a message that gpu drivers have stopped working and recovered ( on both amd and intel ).
2. If the screen blacks out, on rare ocasions if you close the laptop lid and let the laptop go to sleep , when waking up screen works again ( noticable due to screen moving)
3. I tried installing 4 different drivers all with clear install. ( didn't work)
4. I tried to to recover system with restore point. ( didn't work)
5. I tried to lower the screen brightness. ( didn't work)
6. tried this trick:
Turn off laptop
Remove battery
Hold the power buttong for 30-45 seconds
Plug-in the charger ( dont put the battery in )
Turn on laptop and see if it works.
Very Noticable details:
7. Since on of the rare fixes requires to move the lid i tried shaking the screen a bit or pushing it slightly to different directions. This actually does the trick and turns the screen back on ( i am right now typing this after using this "trick"
So, with this one as a hint there are a couple of stuff i have in mind but i am not sure and need help since i am not a technician.
a) There is a loose LCD cable and when i type a little vibration moves it and ends up in a black screen.
b) I read that if you use a flashlight and you cant see your desktop it means its a bad inverter.
c) Can the inverter have a lose cabe instead of the lcd ?
That's all the feedback i could give you that i can recall now.
Currecntly the screen looks ok ( maybe its the certain angle it has after i moved it so i would aprecciate a fast reply before it goes black again
EDIT: Tried to play a game for a few mins and i got the black screen again. Closed the lid so the laptop goes in sleep mode then opened it and it worked. Just for the records.
EDIT#2: Just tried to play a game again. got the blackscreen, shaked the screen a bit and it worked but for the 1st time i get the message " Application has been blocked from accessing graphics hardware" , Can it be that its the GPU after all or maybe drivers?
EDIT#3: Tried to play a game again and it seem to trigger the issue . ( i am currently running the laptop with only the intel drivers installed)
thanks in advance
Sincerely,
Ntas
P.S. Please feel free to ask me any question if you need more information, i am not a laptop expert but i know more than the average person
This question was solved.

Hi @Ntas
I have read through your post and it seems there are a couple of possibilities, and I noted that you have already tried several of the things I would normally suggest.
I will however post some of those links anyway for you to review, it is always possible there may be something in one of them that may have been missed or may inspire an idea of the cause. Since you mentioned that sometimes just moving the screen will cause the problem or make it disappear, that does seem like either a loose connection or maybe something like pressure on a part of the display causing the issue. Of course that last part may just mean the display is on its last legs, but hopefully not.
First I will give you a link to the service manual, to help you check the connections. Just be careful to read the sections on precautions, to protect yourself and to prevent any other damage.This manual is also useful in that it lists all the compatible parts, so if the display is defective you could use this guide to help order a compatible replacement if you choose to do so.

Screen blacking out?

I am curious to know if anyone else has had an issue with their screen blacking out while using the number keys during a call? This has happened four times to me, and I called Verizon, but thought maybe I had put my finger on the on/off switch by accident. However, this happened Saturday again, and I was SURE I did not touch that area of the phone. Please let me know if this has happened to you so we can document this issue with Verizon/HTC.

I am having the same issue. It blacks out or the screen flashes like it is "waking up" but doesnt fully wake up. It has happened on and off over the past two weeks. I thought it was due to a message coming through or a call but that's not the case. I will have to bring it in to see if it should be replaced. I am also experiencing ALOT of dropped calls. I have reset the phone but the issue happens as soon as I try to make the call again..... It driving me nuts.

Help Screen blacked out in 64 bit apps in CS5

I recently installed Production Premium CS5 and the AE/Premier Pro/Photoshop 64 bit apps have a portion of the help screen blacked out. I have spent 5 hours on phone with Adobe technical support and they have been unable to resolve. Has been escalated to level 2 support. Essentially the search box in left frame and the top of the main page consists of all black. This makes it impossible to see what has been entered in search box or where the tabs are to click for various options.

Issue was resolved by removing all Adobe Applications, including non CS5 programs like Presenter, AIR,Captivate, Acrobat and then reinstalling Prduction Premium CS5. After using Control Panel to uninstall applications, used Adobe's clean programn http://kb2.adobe.com/cps/829/cpsid_82947.html to remove all reminants.

My screen blacks out and computer starts up again due to an error. Anyone any suggestions what could case this?

Hello nattygrimm,
I was looking into the issue you are describing and found a great resource to try and fix the issue without having to re install the OS. It is an article called Mac OS X: How to troubleshoot a software issue found here: http://support.apple.com/kb/HT1199.
I recommend starting here:
The first and easiest test to try is to see if the issue affects a different user account on your Mac. Each user account has customized preferences and other items stored in its home directory. You'll first need to create an additional user if one does not already exist (follow steps a-h below). Then, log out of the current user and test the issue in the new user account.
If this resolves the issue, there may be an issue with a file in the home directory of the original user account.
From the Apple menu, choose System Preferences.
From the View menu, choose Accounts (or choose Users if using Mac OS X v10.2 or earlier).
Click "+" (or click New User if using Mac OS X v10.2 or earlier).
Give the new user a name and short name.
Mac OS X v10.3 or earlier only: Click the Password tab, and give the user a password.
Mac OS X v10.3 or earlier only: Click Security.
Select the checkbox for "Allow user to administer this computer". This makes the user account an administrator.
Click OK, or quit System Preferences.
Work your way down the article as needed.
All the best,
Sterling

Intel-based Macs: Resetting the System Management Controller (SMC)

Does anyone know how to solve my Ipad from blacking out during apps?

My IPad is blacking out during apps and going back to the main screen. It will do it in Outlook, Internet as well as games. Does anyone know how to solve this problem?

Sometimes its bescause you have to much memory being used up. Id try:
1. Double tap the home button to bring up the bottom. Hold your finger down on any app until they wiggle. X out of any apps you are not using.
2. Reboot. Hold the home and power button at the same time. Ignore the red slider. Until the screen goes black and the apple logo appears.
Try your game or app again. I know if you have a bunch of stuff running in the background, and run a game like infinity blade or a high processing game. The app will close on you.

The Screen blacks Out

When I try making a call the screen blacks out for a min and then comes back after a while. Sometime it goes black for a second and comes back as well. What could be the problem?

That would be a good plan. Just connect to iTunes and select "Check for updates."
