I Start up iMac -- i hear it but display screen remains black?

Try starting your iMac with the original DVD that came with the computer. Then run Apple Hardware Test. If you are not able to see the screen you will need to take your iMac in for repair.

  • IPhone black screen does not show anything, but I can hear that the device works. I hear the lock open the screen and hear the iPod but the screen remains black

    IPhone black screen does not show anything, but I can hear that the device works. I hear the lock open the screen and hear the iPod but the screen remains black!!

    It's happened to me before as well. Try holding both lock(top right) and home buttons simultaneously until u see a slight flash of wight then just reboot it normally. If that doesn't work try restoring your device from itunes

  • Our brand new quad core imac will not start up.  We hear a drive and fan noise but the screen remains black. Any suggestions?

    The computer shut down on its own while we were gone and will not start up again.  When we press the power button we hear drive and fan noises but no chime and the screen remains black.  Any suggestions?

    A pretty common thing for computers that have been shipped is a RAM chip becoming dislodged just enough to cause what you are describing. Try re-seating your RAM chips. Basically just pull them out and push them back in. Take a look at this article if you need some direction on this: http://support.apple.com/kb/HT1423

  • My iphone 4s is charged and I can tell that its on but my screen remains black. Are there any tips that can help before taking it in to the apple store?

    I've already tried turning it on and off as well as pressing the sleep/wake and home button together to restart but nothing has happened :/
    This is also the second time its happened to my phone as well, the first time it miraculously turned on by itself after an hour

    Hi katherian!
    I have an article here that can help you troubleshoot this issue:
    iPhone: Hardware troubleshooting
    http://support.apple.com/kb/TS2802
    Will not turn on, will not turn on unless connected to power, or unexpected power off
    Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
    Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    After at least 30 minutes, if:
    The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
    The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
    Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
    If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
    If the display turns on, go to step 4.
    If the display remains black, go to next step.
    Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
    If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
    Thanks for using the Apple Support Communities. Have a good one!

  • My Imac 27' screen is shutting off for no reason. The Imac is still running but the screen is black and stay like that. Is there anyone else with the same problem, and does somebody know what is this?

    I had my Imac27' for about 1 year (I bought it january 2011) , and it worked fine. But two days ago a problem started. The screen is turning black suddently, and it stay like that until I reboot it. It's not cool. The first time it happen it was hafter a very long days of video editing, I tought it was to hot. But now I just started up the Imac and 10 minutes later it happen. And now  I transfer my desktop on my second screen, because the one of my Imac is constantly shutting of. What is this? Can I do something about that?

    I´ve came across with the same problem and when I look out for solutions I found out that basically I had Three options
    1.- Dim the brightness to the first 2 dots (that is the limit for me, anything above that shuts down again my screen)
    2.- Replace an expensive part of the screen (about $900)
    3.- Try with an external monitor to see if the problem was the screen or something else
    What I did was to plug my flat screen to my mac with a Mini Display Port to VGA Adapter
    http://store.apple.com/us/product/MB572Z/B/mini-displayport-to-vga-adapter?fnode =51
    And… Problem Solved! now Im going to buy a Monitor that gonna cost me less than half of the replacement parts, my main monitor will keep siting down if i dim it above the 2 dots but at least I will have the other to work properly
    So that´s that, I hope someone finds this helpful
    P.S. Sorry if my english it´s not that good

  • I was watching movie trailers in itunes and now I can hear it but the screen is black

    I was watching trailers while waiting for a movie to download in iTunes and now the trailers have sound but I see no images.
    Help!

    I think the key word here is "was". You can try a reset. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. The phone should reboot. If this does not work, then it is possible that the hardware has failed. Make an appointment at the Genius Bar at Apple or the Authorized Apple Service Provider.

  • IMac g5 screen remains black when turning on

    My iMac 2.0 gz ppc g5 froze up while net surfing. I turned off power strip and when I turned computer back on all I hear is the fan running, the power white light is on but the screen remains black. Am I in some weird sleep mode? Or worse? I' m running 10.5.8

    Try rebooting in Safe mode:
    To start up into Safe Mode (to "Safe Boot"), do this:
       1. Be sure the computer is shut down.
       2. Press the power button.
       3. Immediately after you hear the startup tone, press and hold the Shift key.
          Tip: The Shift key should be held as soon as possible after the startup tone but not before.
       4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
    During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
    During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
    To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

  • HT201177 When I turn my computer on, I can hear it starting up but the screen stays black.  Anyone know how to fix this?

    When I start up my compute, I can hear it starting up but the screen stays black.  Has anyone else had this problem and found a fix?

    If you press the caps lock key does it light up? If it does then this indicates that your system is booting but the display is either not recognized, is not displaying any video, or the display is displaying video but the backlight system is not lighting up. As long as you've tried turning up the brightness then there is not much you can do other than take it in for a diagnosis. If you have a very bright flashlight you can turn on the iMac and then shine the flashlight onto various areas of the iMac display to see if you can see any faint images on the display. If you do then this indicates that the display is displaying the image, but the backlight is not turning on for some reason. It doesn't change the outcome, but at least you can assist the technician who is troubleshooting your iMac.
    Please let us know what you find out.

  • My imac turns on.. but the screen doesn't!

    I woke up my computer from sleep one day by using the mouse and then it brought me to the desktop... then it froze. So, I simply did force shut down by pressing the button. Now when I press the power button, computer turns on (I hear the fan and CPU turning on) and the light on the bottom right corner lights up, but the screen doesn't show anything; it remains black. There is no dong startup sound or apple logo startup or anything. I tried doing the PRAM reset (that did nothing since I can't see the screen anyway). I have no warranty or anything. Can someone help me with my issue? Thanks.

    Did resetting the SMC help for you? Or have you found another solution.
    I ask because the iMac I have is doing exactly the same - the disk spins, fan makes noises, white sleep light comes on (permanently) but the screen stays black.
    Resetting the SMC did not work for me plus I also tried removing the RAM and re-inserting - still no joy.
    I also tried the thing where you plug the power cable back in while holding the on off button in - in this case the fan just went onto maximum speed until I turned the iMac off again.
    Any help will be appreciated.
    Thanks
