My display starts up with a black screen or fades to black after being on.

So just recently when I would turn my mac on, it starts up with just a black screen. The computer is on just no display. Sometimes it will take multiple times of restarting the computer to get the display to come on. When the display is finally on and working fine I found out that if I touch the top of the iMac near the iSight the screen will then slowly fade to black. And of course, the only fix is to restart. Anyone have a similar problem? Unfortunately I didn't purchase the extended warranty and my computer is one month past the 1 year mark. Thank you.

Restart the computer with the Option, Command, P, and R keys held down, and release them when you hear the second startup chime; this clears a setting which causes it to start up into verbose mode each time.

Start your iMac with the original DVD that camera with the system. Then open disk utility and repair your hard drive, also repair your permissions.

How to start MacAir with frozen blue screen and no light on keyboard?

How do I start my MacAir with frozen blue screen and no light on keyboard?

Hey 7manya,
Thanks for the question. I understand that you are experiencing an issue with your MacBook Air frozen on a blue screen. The following resource provides some troubleshooting steps that may help to resolve your issue:
OS X Mavericks: If you see a blue screen at startup
http://support.apple.com/kb/PH14061
If you see a blank blue screen or a blue screen with a colored pinwheel when you try to start your Mac, but starting up doesn’t progress, you may have a problem with damaged or incompatible startup items or software.
- If you are starting up from a DVD, it must be a disc that came with your Mac or OS X retail package. Discs from other Mac models may not work with your Mac.
- Restart your Mac in safe mode. If the Mac successfully starts up in safe mode, choose Apple menu > Restart to see whether the Mac will restart normally.
Start up in safe mode
- If you see the login window prompting you for a user name and password, but starting up doesn't progress, you may have incompatible login items.
If you think you have incompatible login items
- Repair your startup disk or disk permissions using Disk Utility.

T43p black screen, back for a few after standby

hi,
i have a t43p, and recently, the screen has been going black after just a few moments of being on, between 1 and 7 minutes, average about 2-3 minutes. in the black screen, sometimes i can still see (dimly) what's going on 'behind' it.
i've recently installed 2 updates to antivirus/security pieces of software, and after that some issues/malware/1 trojan were found. i was thinking that may have been the problem. but they'\re supposed to be quarantined, and i reinstalled & rescanned everything, and i still get the same problem. but while a scanner is running, my screen stays up a lot longer (closer to 20 minutes) and in between, it'll often go to a screensaver (still, while the antivirus is running) and i'm able to function normally at that time. but now, scanning again, at 32minutes, my screen finally went black again, and to get it back i have to fold my laptop down almost to closing, have it sense hibernation, then it comes on fully. and then it goes straight to standby. after i see the little hibernating moon light by my battery come on, i press the 'fn' button to wake it up, it takes me back to the username screen, then i press my name and i'm back to where i'm started.
and now, during this same scan, i just did all of this after 32min of being ok, and as soon as i completed the process of hibernating to wake up, it lasted only 30 seconds, then went back to black. i'm going through the re-animation hibernation technique again now to get it back up.
i've tried running pc doctor, no problems, although i didn't get through everything, b/c of the blackscreen all of the time. but i did get through all of the video section, and a few others connected with the processor and other components.
right now i have the newest ad aware running the scan and avg 2012 as my root antivirus.
also, recently i tried running a game (sims 2) and it told me that directx wasn't found/ needed an update. i thought that was funny, b/c i've run that game a few times w/no problem, but i went and found the most recent update from the microsoft site, and end user something or another...i can find the whole name if it's necessary. after that install/update, the game ran fine and things were ok. that was about 2 1/2 days ago.
the screen just went black again, after 1.5 minutes of being ok.
thanks for your help and reading all of this. i'm trying to be thorough so you can have some good info to fish from.
take care and i hope to hear from you soon,
jt hendrix

Hi,
I don't own a t43p, so there may be any issues I'm unaware of, but in general, it sounds like either a bad inverter, or screen assembly. The fact that you can see images faintly is significant, it means your backlight isn't working, but the question is, did it turn off because the system told it to, or because it's failing. I'm not sure which.
First thing I would do is disable the "shut down display" option timer for both battery and AC power. I'd also disable the "close lid", changing it to "do nothing" when the lid closes. At very least this may let you cycle the inverter switch (magnetic switch in lid that turns off screen when lid is closed), so you can avoid going to sleep/hibernation. I do this with all my laptops because I like to be able to close the lid without it stopping.
Now if the problem persists, and cycling the lid closed/open turns it back on again, then my best guess would be the inverter. They aren't very expensive, but requires some disassembly of the lid, or you can get a used complete lid assembly, that would be the easiest and fastest way to fix it, but I'd wait until some of our other members can suggest anything I may have missed, or perhaps one may have a lid assembly...
Good Luck

HELP!! Black screen on my MacBook Pro after leaving open and on for over 8 hours.

Hi everyone,
This is the first time I'm using the discussion board as I haven't had any problems with my MacBook Pro since I bought it in November 2010. However, yesterday, I left my laptop on and open for over 8 hours without realising. When I came back to my laptop it had a black screen that just wouldn't go away. I pressed all the buttons on my keypad to wake it up but this didn't work. The caps lock key lights up when pressed and the volume button makes the clicky noise when turned up and down but the screen is still black. I have tried turning the laptop on/off using the power button several times. When it starts up it makes the usual sounds and I can hear that it is on but the screen is still black.
I do not use my laptop for anything complicated. I really only use it to browse the web. I hope someone can help me. I have tried to make an appointment with the Genius Bar but there are no available appointments at my local one. I'm not a mac expert and don't understand technical words so please speak in layman terms otherwise I won't understand. Any help would be greatly appreciated. Many thanks

Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
Kernel Extensions in backtrace (with dependencies):
         com.apple.GeForce(6.4.0)@0x82ac4000->0x82b7afff
            dependency: com.apple.NVDAResman(6.4.0)@0x834a0000
            dependency: com.apple.iokit.IONDRVSupport(2.2.1)@0x82fd3000

            dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000
Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. They should be more than willing to install a new logic board at no cost. I have no idea why this faulty GPU is making the headline here on the MacBook Pro forum so often now - could it be because Mountain Lion is just bringing the issue to a head more readily? I don't know - I only know that we're seeing more and more of these kernel panics of late.
Good luck,
Clinton

Phone stuck in recovery mode complete black screen will not turn on after recovery and update there was an error and now computer and itunes will not recognize the phone....Anyone know what I can do to get the phone recognized again when it cant be turned

Phone was not updated on time so it automatically shuts off and you get a plain black screen until it is recovered and updated. Well when i did the update and recovery I received an error. I went through the steps to fix the error, I had to restart my computer and now the phone isnt recognized on my computer or in itunes. The screen is still completely black so pushing the home button and plugging in to computer still does nothing. Device manager shows nothing in usb port, and apple mobile device software is installed and running. Any help?

Hello agardner37701,
I found some steps you can take when your iPhone is not recognized by iTunes when in Recovery Mode. I recommend reviewing the steps in the section titled "If the device is not recognized while in Recovery Mode" under step 5 in the following article:
iOS: Device not recognized in iTunes for Windows

My screen flickers/fades to black

Screen flickers, sometimes fades to black screen completely, have to hold down power/home button at same time for a few seconds until Apple icon shows back up and sometime it doesn't. Any solutions to this??

First I would buy the correct charger from your local Apple Store or Apple reseller. If that doesn't solve the problem and if the machine is covered by warranty or AppleCare (yes Apple warranties are transferable) make an appointment at your local Apple Store and take it in.
Good luck,
Roger

Black Screen on switch to tty after install proprietary catalyst-hook

After Install the latest version of :
catalyst-total 14.9-1
from AUR I can startx and login to x sessions, But I can'nt switch to tty right after that executing startx and entering into X Also after suspend.
When i pressing C+M+F2 or even logout from X Session Then i can'nt access to tty consoles and just a black screen appears and nothing work even my mouse.
I have followed wiki and some forum workarounds to this issue for example disabling KMS or put vga= kernel param on grub,...but none of them dose'nt solved the problem!
I have a ATI 6470M card :
# lspci -nn | grep VGA
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Seymour [Radeon HD 6400M/7400M Series] [1002:6760]
also I have installed following:
linux -> 3.16.4-1
linux-headers -> 3.16.4-1
xorg-server -> 1.15.2-1
Any idea? please.
Sorry for my english

I also use a Samsung N220 and found two ways to avoid this issue:
intel_idle.max_cstate=0 as a kernel boot parameter
disable CPU power saving in BIOS settings

MBA Black Screen - and ALWAYS is black (will not boot into OS)

I've read and done everything. Many are saying they are able to get a restart and change settings - but I can not get pas the black screen at all. I continue to do a hard restart, it goes to black screen. I use the control-option-shift-power, and it powers back to the gray screen, then black again. I do the command-option-p-r and it goes to gray screen then black. I can't get it into the OS to even change the settings.
I even tried the connection to a TV and it also is black. This is a constant cycle to the black screen.
I don't know what version the OS today, but I know I have updated once in the last 30 days, but not in the last 2 weeks (manually, I have not).
Any advice to get to the home OS screen, so I can adjust settings?
2012 MBA

OS is 10.9.2.
I booted into command-r to get to the Time Machine backup from Jan 25th of 2014. I have a screen that I can see, but when I restart (I have not restored from backup), it goes back to black screen. I AM WONDERING now if I should just restore, then work on the settings for the black screen ??

When shutting down from Start button with Firefox running, screen freezes, will not complete shutdown and I must manually shut down. How to fix?

win 7; 32 bit OS
Firefox 23.0

Thanks for posting back. Glad Firefox continues to work.
Most programs try to do a bit of a cleanup routine as they closedown so it is usually best to close them down properly.
You will presumably have options to make the computer sleep, that needs power; or hibernate, that needs no power but may need spare RAM memory.
* http://windows.microsoft.com/en-gb/windows7/sleep-and-hibernation-frequently-asked-questions
No doubt you have already discovered
* You can opt for Firefox starting with home pages or starting with the last opened Windows. <br />Even if starting from home pages the History option usually allows the last open windows and tabs to be reopened
**[[Startup, home page and download settings]]
* If something goes wrong Firefox tries to give you the ''embarrassing'' screen with options to select what opens from last time.

How to get rid of a black screen on an HP g62 after disk corruption check?

I recently started up my computer and got a disk corruption error and I let it run through and it started up normally. Yesterday I got the error again and let it run once more and found that the laptop was deleting files. Now when I start it up all I can get through to is the log in screen and when I log in all I see is black with a cursor. Could it be a virus? I have an HP G62 with Windows 7. I recently found that I needed to update my virus protection but it wasnt urgent. Please help.

Could you please give me the exact model number of your notebook?

Black screen on Satellite A100-712 after Bios update

I bought a new Satellite A100-712 and i did a bios upgrade, everything went well in windows and when the laptop got restarted it is stuck on the black toshiba screen which is displayed when we switch on the lapto.
Any suggestions please, I would be very thankfull

> i doubt toshiba didnt verify the drivers properly for all models
Sorry but I do not agree with you. BIOS update is very sensitive part of notebook upgrade and exactly there Toshiba must be 100% sure that everything works well. As I said in my previous posting I have updated BIOS on two WXP delivered A100 notebooks. One with number PSAA9E and other one with number PSAA2E. BIOS update on both units was successfully finished and I can confirm that offered BIOS on Toshiba download page is the right one.
Which model is your A100 (PSAxxx)? I have made BIOS update on PSAA9E because of VISTA OS installation. What is your reason for BIOS update on your A100?

My display starts up with a black screen or fades to black after being on.
