Why is part of the screen blacked out?

I'm using Acrobat.com from my desktop on a computer running Ubuntu.
I attach a screenshot of my desktop with Acrobat.com running.
Can I get rid of the black box at the top left?
Thanks.

Thank you for your post. Never seen that one before. Officially, support for Linux is limited... have you by chance looked over these instructions?:

Not sure what version of Ubuntu you're using. Let me know, and I'll try someone here for escalation.
Any other linux folks out there know how to help?
Cheers,
Michelle

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."

Updated to Mavericks and I get the upper left quarter of the screen blacked out on Time Machine. This means that I can't see the files. Any suggestions for getting rid of the black square?

Ive tried disconnecting and reconnecting the Time Machine. And I've tried rebooting the iMac, but I still get the top left hand quarted of the screeen blacked out. I can scroll back through the back-ups but the back square means that I can't see the details of any file.

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, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in 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, reboot as usual (i.e., 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.

Macbook pro screen blacks out

I just bought my first Mac. I have noticed since I received it a couple weeks ago, that the screen blacks out occasionally. I am pretty sure this mostly happens when I am in Safari. Any ideas why? This will happen with my ipad 1 every once in a while too. It will black out and revery back to the home screen.

You should take it into the store as it certainly could be a hardware problem. In my case, however, i didn't notice it when I was on Lion, noticed it on ML, and then haven't seen this problem again since downgrading to Lion.
Since your problem is intermittent, it might be hard to produce at the store. So, you might want to try to capture it on video before you go to the store so you have something you can show them.

Screen blacks out after a few seconds and won't return to normal state.

I have the 30 gig ipod photo that i got about a year and a half ago. Whenever I look at the screen to access music or anything, the screen blacks out like there's a screensaver or something and won't return back to normal. Even after I reset it, it stays normal for a few seconds and then blacks out again. The backlighting still works so it's just a bright black screen and I have function of the click wheel because it clicks everytime I move up or down. I already tried restoring it so I am all out of options. Anyone PLEASE HELP!!! Thanks
Steve

This happens rarely but consistently! I't seems to happen about 5% of the time waking from sleep. It MAY be more prone to happen if I had been moving with it in my bag, but it can happen at any waking time after any duration of sleep.

Windows XP mouse halted and screen blacked out!

When I boot up with boot camp and dragging some windows size (like IE or Excel). The mouse pointer halted and after a few seconds the screen blacked out just like the machines is turned off. However, I discovered that the system is still running. I can perform the shut down action by input from the keyboard.
The problem does not exist when I start windows xp through VMware Fusion.
Did anyone encounter the same problem??
I just bought the iMac a few days.

Thanks for your reply, I have a wireless mouse/keyboard & called manufacturer to test both & they told me to plug the wired ones in & they did not work & the laptop has no plug for wired ones because those have rounded ends, laptop has wrong size/shape usb ports, so there is no way to test them on laptop, so now I'm hoping you or someone has an idea of what to do next, thank you for your ideas.

E6-00, Screen blacks out as soon as a call is rece...

I'm posting this on behalf of a friend who has asked me to take a look at their E6-00 which has a problem that when a call is received the screen blacks out instantly and therefore she can't see the caller display.
I've read elsewhere that it is an issue with the proximity sensor on the front of the device but nowhere states if there is a definitive fix for the problem.
This did not happen prior to the phone being upgraded to Anna. I have since upgraded it again to Belle in the hope that this will remedy the issue but it's still happening.
Can anyone advise if their are any OTA updates or downloads that will sort this out or is it just a "live with it" firmware flaw?

Try do the soft reset (Restore Factory Settings in the Settings). If it still doesn't work well, try to do the hard reset. Before doing this, please create a backup as the hard reset will remove all your files.
If the hard reset does not even help, you may have to take the phone to the nearest Nokia Care.
Let me know if it works.
If I have helped you in any way, give me a kudos!

Nokia 2610 Screen Blacks Out

could someone please let me know how to stop my 2610 screen "going black" after about 25 seconds. It seems to be a sort of power / screen saver mode.

I have the same problem and have set the both power saver and sleep mode off, but still the screen blacks out.
Any real solution ?
Thanks
I think thats the power save mode which is a builtin feature of this phone, i have a nokia 2626 but it doesnt seem to have this. maybe if a firmware update can take care of this issue
the conenctivity of 2610 is fine but 2626 isnt connecting either by Nokia pc suite or Mobimb 3.2

Screen blacks out!!! HELP

hi! everytime i use itunes visualizer full screen (the new one on itunes 8), after a short while, the screen blacks out. it's not sleeping or in energy saving mode because if i tilt the screen enough, i can still see the screen display, just that there's no backlight on the lcd. really weird, and this has happened about 3 times already. i had to lower the brightness and bring it back up a few times before the screen would restore to normalcy.
what's wrong? should i send it in for repair?
cheers!

Sounds to me like an issue that requires service.
You can arrange online service here.

Or if an Apple store is near you, take it there and have them check your iPod.

Why is my iPad 2 screen black? How can I fix it?

My brother just dropped our iPad 2 and when he picked it up the screen was purple. He then turned it off and when it was back on it was all black. I can hear the lock sound when I lock it it's just that the whole screen is black. The funny thing is he dropped in on a carpet from not a very great height. So how can I fix it? Please don't tell me to reset/turn it back off because I have tried this multiple times. I haven't tried restoring it though. Will that help? Will appreciate all advice. Thank you greatly!

My first instruction may well be exactly what you've done but I want to ensure that we're talking about the same thing.
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

14" iBook screen blacks out

This is the third time it's done it today and the 5th time ever. My AppleCare ran out the middle of March, so I guess they are right on in determining when it's time to get a new computer.
When it blacks out, it just goes immediately, no flickering, no warning whatsoever. I can still see the desktop underneath the black and I can still move the cursor. I don't know anything what the insides are like, but the apple light on the top of the case goes out when the screen blacks out.
When I closed the top and opened it again, it brought the screen back up right away. But this last time, it took a few closing and openings to get it to come back up, making me think it's going to get worse.
Last week was the first time it ever went black. I initially thought it was falling in to sleep mode and held down the power key to get it to reboot. I'm pretty sure sleep has nothing to do with it, but I set my display to not go to sleep at all today to find out. It's blacked out twice since.
I don't use a screen saver, it's happened on battery and power adapter. Other people have mentioned the fan not running, I can't remember ever hearing my fan run or else it's just so quiet I can't tell the difference between it and the hard drive.
My iBook is a late 2004 model 14" 1.33 and, I just upgraded to Tiger (coincidence?) There have been no other problems to speak of other than the keyboard losing letters, battery needing to be replaced and the usual airport glitches. It hasn't been dropped or spilled on. Any suggestions on how to fix this and what I might be looking at when/if taking apart the screen?

It sounds like you might have a bad inverter cable, especially since it is affected by the position of the display. I think this is just a mechanical failure of the cable caused by many openings and closings of the display.
You might check out the troubleshooting section of the ifixit site and read about the inverter cable and see if it sounds like what is happening to you. I gather it is a real job to replace it. Ifixit and Powerbookmedic would be two good resources:
http://www.ifixit.com/
http://www.powerbookmedic.com/
Since the job is considered very difficult, I'm not sure there are any instructions on how to do this on these sites. But there is another manual that might be helpful:
http://node123.cit.geneseo.edu/~stratton/ServiceManuals/
This is just the index. You will have to find the one for your iBook. Powerbookmedic also has a good manual.
It may also be possible to repair the cable, but I don't know. Spudnuty is the real expert here, and hopefully he will see this and be able to offer you more specific advice.
Good luck!

Black plastic part under the screen is loose (MBA 11,6)

The black plastic part under the screen is a little loose. If you press with one finger you push it in and it will move a bit. Anybody else got this problem?

Hi, was it covered under your one year warranty, I opened my Macbook Air one day and heard a crack, when I looked in the back of the computer the hing had broken and something was hanging out of the back. When I tried to close it the screen turned green and then went off, so I took it to repair however was told it probably wasn't covered on the warrant. From googling the issue it appears that many other users have experienced the same thing. I'm assuming if enough users complain it will eventually become covered!
