Flickering Powerbook Screen then goes completely black

My powerbook screen has started flickering and then goes black. I can still see faint images on the screen, so it has not died. When it does go black I can get it to come back on by holding the the screen dimmer button down and then taking the brightness back up. The same thing will happen almost instantly. Any ideas?

Hi, I had exactly the same problem. It lasted over a year, when I positioned the display horizontally it worked fine or when I placed a laptop against a wall or something that would very lightly push the screen from the back (even a finger touch). Sometimes the display found its good position and could stay without any support for few days. So it didn't make me go repair it immediately and I kind of got used to it. Until last week when it flickered for the last time, stayed black a no pushing or no dim button would help and made me overcome my laziness to drive to Apple center. It cost me 500 shekels in israel to repair, it's around 150 USD. The repair report says that board inverter was exchanged.

    Try starting your iMac with the original DVD that came with the machine then launch disk utility to repair your hard drive.

  • Laptop screen goes completely black but shows that it's still on

    Hello everyone, i'm in need of serious help!
    I bought this laptop over 2 years ago (October of 2008 to be somewhat exact). It's a Windows Vista Home Premium, with service pack 2.
    its an HP pavilion dv7 notebook pc
    processor: AMD Turion (tm) X2 Dual-Core Mobile RM-70  2.00 GHz
    Ram: 4GB
    system type: 64-bit operating system
    im assuming the video card information are as follow:
    name: ATI Radeon HD 3200 Graphics
    chip type: ATI Radeon HD 3200 Graphics (0x9612)
    DAC type: Internal DAC (400MHz)
    total memory: 1914MB
    memory: 3836MB RAM
    page file: 2163MB used, 5732MB available
    current display is 1440 x 900 (32 bit)(60Hz)
    directx version: directx 11
    with that being said... here's my dilemma...
    Each time i play the video game, "World of warcraft", my laptop's screen goes completely black but it shows as if though it is still on. I can't see the screen but it shows that it is still on by the little lights on the bottom of the screen.
    I took my laptop to a family friend who knows a lot about computers to see if they can fix it for me. They told me that everything was running fine, everything is okay, the ram, memory, graphic card, everything passed the test, and it was not over heating... there was nothing wrong with my laptop. They THOUGHT it could be the motherboard, so they tried it, but in the end, it wasn't. Unfortunately the problem was not solved.
    I played World of warcraft on this laptop before. When i first bought it. It ran smoothly and gave me no problem whatsoever. I'm clueless is to though why it's giving me problems NOW.
    Could anyone please please pleaseeeee help me? i have given up already. I have done everything i could. Please help me! i believe i have done a total one 1 or 2 system restore to factory settings, the 2nd one was recently (probably a month ago) and i'm not sure if maybe perhaps i needed to DL something else? i have DL all the updates that microsoft offered to me when needed and when it was necessary, but this particularly problem was never fixed.
    someone please help me! Thank you so much!

    erichon99,
    I think i may have found MY solution but i have yet to test it out... No one helped me. No one at all. I took my PC to a family friend company and they did everything for me: ran tests to see if my laptop is up to date with everything, removed graphic card and put a better one and nothing still. They thought it was my mother board but they ran tests again and everything on my laptop past the test. My graphic card was fine, ram was perfect, memory was perfect, everything everything on my laptop was perfect. They couldn't find out what was the problem. I took it to best buy and not even them could help me. When i was about to give up, my fiance, he did some research and found this guy on youtube who does LIVE recordings and answers people's questions. My fiance asked the question and he got serveral responses. Out of 10, i would say about 2 or 3 of them mentioned, "it's the power cord" the rest said it might be virus, or a card is not working properly, etc. You can give it a shot (buying a new power cord) those who told my fiance that it could be my power cord, said to get those power cord that has a fan in them.
    I think this makes sense because my screen goes black only when i'm playing a game. even when i play cityville on facebook it goes that black screen, but it doesn't go black, it does that pixelated, rainbow, warning bar, thingy (i hope you know what i mean lol) and when i touch my power cord to my laptop it is BURNING hot. What i do is, when my battery is fully charge, i disconnect and play my game, and to not lose any docs i left open, i close my games, and plug back in. I've been lazy to find another power cord lol i guess i should start now, huh? lol
    i hope this help. I would say (if you've done everything like how i did) buy a power cord that matches your laptop, but with a FAN in it (i was told it's the best and you'll never have that problem of freezing or whatever)

  • My iPhone screen is frozen on white light (then goes to black).  I tried to reset with no luck.  The phone will ring but can't pick up a call.

    My iPhone screen shows only a white light when on, then goes to black. 
    I tried to reset, with no success, and I
    synced to computer again, with no luck either.

    Try to set it up as new device, explained here:

    First without using the backup, in case it contains corrupt data.
    If it works after that, use the backup to restore from.

  • IPad goes completely black while using it, comes back in a few seconds

    iPad goes completely black while using it, comes back in a few seconds battery doesn't hold charge either

    Try a Reset [Hold the Home and Sleep/Wake buttons down together for 10 seconds or so (until the Apple logo appears) and then release. When the screen goes blank then power ON again in the normal way.] It is 'appsolutely' safe

  • My screen saver goes to black after a few minutes of running...any idea why?

    I've got a brand new macbook pro. I just did the set up of the screensaver which draws from a pictures folder.  The screensaver starts like it is supposed to but after a very brief time of running the screen just goes to black...no more screen saver.  Any suggestions for what I have set wrong or what I need to change?
    Also, when I'm loading a batch of pictures to my machine from my memory card is there a way to go through them and easily delete the ones I want to trash in a large screen (ie in preview or iphoto?)  I don' see a delete button of any kind.  For example in Micorsoft Office picture manager there's an 'x' and if you want to dump the picture while you are previewing them all/editing you can do it right from that screen.
    Thanks in advance for any helpful suggestions!!  I'm a newbie to Macs (20 year PC user) and a little lost at the learning curve!

    From the menu bar, select  ▹ System Preferences ▹ Energy Saver. Set the Display sleep slider to an interval longer than the interval at which the screensaver starts. For example, if the screensaver starts after 10 minutes, set the display to sleep after 20 minutes. You'll then get 10 minutes of the screensaver, followed by a blank screen. You can set the slider to Never, if you like, but that will waste a lot of energy over the life of the machine.

  • Equium A210 - the screen just goes completely blank

    Hi there,
    I've recently purchased this laptop and I am generally happy with it. However a few times, the screen just goes completely blank (black screen) preventing me to do anything. I end up having to turn it off manually and restart it. Does anybody know why this happens or has anybody else experienced this problem?
    If not how do I get this problem to Toshiba, is there a specific e-mail address?
    Thank You for your help,

    I have registered similar issues on different notebook series running Vista. Its no matter what series it is.
    Im sure its a Vista issue and should be solved with the new SP1.
    But note; the SP1 is not official released and I would recommend waiting till an final version was published.
    I read that the SP1 beta version makes some troubles and is not fully compatible with some drivers.

  • I am having problems with my macbook pro and the dock.  About every fourth time I start the computer, the dock flashes on and off, then goes completely off and all I get is the spinning ball with brief moments of the cursor.  But the computer locks up.

    Do you have Parallels installed by any chance?  There is a known problem that causes symptoms similar to this.  You do not need to actually be running Parallels at the time and nothing in ActivityMonitor would point to Parallels.  An update corrects the problem:

  • My screen on the imac starts to load then goes to black screen when turned on

    how do I reboot my desktop as when it turns on it starts to  load then it goes to a black screen

    I had the same issue with my 2008 iMac and Apple support walked me through a fix ...
    1. Shut the computer down by holding the power button for 10 seconds
    2. Restart the computer and press shift at the same time until you see the progress bar start moving
    3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.
    4. After a moment, you should see the spinning beach ball
    5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).
    Apparently it's an issue with an automatic update that never quite got past the login screen.
    If this doesn't help then try reinstalling whatever version of OS X you are using.

  • Everytime I start to install Windows into my bootcamp partition the screen goes completely black after installing.

    Hi All,
    I'm using an iMac late 2009 ( Processor 3.06 GHz Intel Core 2 Duo, $gb 1067 MHz DDR3, ATI Radeon HD 4670 256 MB) with OS X 10.8. I've Boot Camped my Mac Book pro so I'm familiar with the steps to do it.
    I've made a partition and downloaded the windows support data to an external hard drive. So I'm at the part where I'm installing windows (I'm installing Windows 7 Home Premium), everything goes smoothly and it installs everything but when it restarts and gets past the loading screen everything goes black and nothing happens. it doesn't get to the point where I put the serial number or set the time.
    I thought it was an issue with my OS X so I removed the partition and re-installed my OS X 10.8. Then I've tried re-Boot Camping and installing windows but still no luck!
    Anyone have any ideas on what I could do next? Any help is most appreciated

    Why it would be OS X?

  • IMac G5 boots, and then goes to black screen

    This is not my iMac, but a friend who is using this that she got from here son who upgraded to an Intel iMac. The hardware is a G5 20 iMac. I don't have any more information since it wont power on....or have the installation disks...
    The symptoms are that the machine will power on, "bong" show the blue apple screen, then the spinning lines and then suddenly a black screen and nothing more. I booted to single user via Command-S and ran fsck to ensure the disk was clean. Ir reported no errors, but halfway through the check the fans came on full. Only having experienced an Inetl iMac's fans, they were very load. When the fsck finished (with no errors) the fans turned off again. When i exitied the shell to reboot, the same thing happened again. Black screen and not repsonse.
    The fact that I can get to single user shell and check the disks points to most of it working, but I'm confused as to why it gets no further.
    ANy help would be appreciated as she want to migrate from her current PC based workflow to a more reliable(!) one, but this isn't helping....
    Thanks,
    Jimmy

    Thanks to the responders for their input. I was fearing the worst. However, it looks like the issue wasn't as serious as a broken capacitor. I don't understand why the following worked, as it's not as if the machine was always not working, but just started.
    As part of the diagnostic process, the back was opened and then the memory reseated. After reboot this still failed. Then Command Option O F to get into open firmware and then
    reset-nvram
    set-defaults
    reset-all
    and the machine rebooted and came up again.
    So far there have been no problems, but it looks like this was the fix.
