    Intel OS X 10.7 iMac has white screen and three-alarm sound, won't start up

    The 3 beeps during start-up are telling you that the RAM is bad.
    If you can access the RAM modules, you may try taking them out and putting them back in, perhaps it's only bad contacts.
    If that doesn't help, you'll need new RAM module(s).

  • 21" iMac getting white screen and does not boot up

    Hi All!
    This is my first time to post here but have been using Mac OS since 2009.
    I am having issues with my  Mid 2011 iMac 21". I keep  getting a white screen and it does not boot up.
    I am a bit technical so I have done all the necessary steps as below:
    1. Powercycle the system (Shutdown, unplug for 10 seconds and replug) = No go
    2. Reset NVRAM several times = No go
    3. Went to Safe Boot = Vertical white stripes on blue screen appears
    4. Tried booting on Recovery Disk = Vertical white stripes on blue screen appears
    I'm thinking my video card is faulty now.
    Any help guys? I hope my hard drive is not fried
    What's worse, my 3 year extended warranty just expired last June and it's only been 3 months

    First i can't send it back becuase it didnt have a warranty i purchased it on ebay. second the guy didnt send the install disks with it as he promised i have tried to follow up with him with no luck so hes been reported to ebay. and due to current buisiness expenses cant afford the new software. is there anything else i can do to at least boot the thing so i can figure out whats wrong with it. and has anybody experienced this before and if so how was the issue resolved. soooo frustrated as buisiness is at a stand still till this machine works. p.s.it has osx leopard latest version.

  • 20" Imac has white screen and freezes at start-up

    my 20" imac will not start....help...All I get is a white screen and tone at start-up then it stays white. I tried hooking up a bootable firewire drive and pressing the alt/option key at start up nothing. I also tried the command/option/p/r at start up, it will reboot to the same screen. I also tried running the hardware diagnostics at start-up...no response. Computer was purchased on Nov .4 2007, warrenty just expired.
    Help......Please....

    I had the exact same problem today. My iMac 20" (iMac 8,1) would't boot any more, staying stuck on a white screen immediately after the normal start-up chime. Nothing worked (no safe mode, no DVD boot, no disk selection icon when starting with alt pressed, no Apple hardware test, no parameter RAM reset, power management chip reset had no effect, no verbose mode, not even open firmware).
    I browsed the forums, but what I found didn't help, so I was about to stop trying and have it fixed by Apple. But my son told me he had noticed that after "a long time" (he's 4...), a folder with a flashing ? would appear. I figured that wouldn't happen in case of a severe hardware failure, so I tried one last thing: I hooked up an old PowerBook in target disk mode via Firewire and restarted the iMac. I tried several times (with and without alt pressed), but nothing happened (when pressing alt, a functional mouse pointer would appear, though).
    Then I restarted a last time and left the iMac sit there on its white screen for about 20 minutes... and that's when the miracle happened: it finally booted off the target-disk mode PowerBook's system!
    I ran Disk Utility, which saw the iMac internal HD as disk2s0 (or something like that), and launched the disk repair process. After about three error-ridden verify-repair cycles, the green ok message finally appeared and the volume mounted as if nothing had happened. I rebooted off the internal disk without a glitch, and I still have to find damaged or lost files.
    I guess I was lucky that my HD problem was benign enough to be cured by Disk Utility. But even if that had not been the case, at least I'd have known that the HD failed, and maybe I could have saved some files using recovery software. Whatever the case, if you've got an external bootable drive, it's definitely worth trying before handing your iMac over for (usually horribly expensive) repairs.
    Good luck!

  • My iPad air2 has white screen and does not switch on

    My iPad Air2 does not turn on. Has a white screen with a black apple logo.
    Tried charging it for several hours but nothing happens.
    The problem started when the battery was drained.

    Hey bwzdragon,
    If your iPad will not start up completely, I would suggest that you troubleshoot using the steps in this article - 
    If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on - Apple Support
    Specifically -
    If your device gets stuck during startup
    When starting up, you might see the Apple logo or a red or blue screen for a long time, or your device might restart again. Try these steps:
    Make sure that you have iTunes 12 or later on your computer.
    Put your device in recovery mode.
    When you get the option to restore or update, select Update. This will reinstall iOS without erasing your data.

  • Ipod touch has white  screen and not responsive

    ipod touch has white screen and not responsive, pls. suggest solution

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

    Hi aldamtgf,
    Thanks for visiting Apple Support Communities.
    If Messages is only displaying a white screen when you open it, first force close the application using this method:
    Double-click the Home button.
    Swipe left or right until you have located the app you wish to close.
    Swipe the app's preview up to close it.
    These steps come from this article:

    If Messages still does not open normally, restart your iPhone next:

  • My MacBook Pro 13 won't start has white screen and beeps

    I used my MacBook pro lastnight and worked fine. Tried to turn it on this morning and it won't start. Does sound like it is going to then before login screen shows ur goes to a solid white screen and beeps every 7 seconds. Need help school is about to start again.

    Check this out.
    I think you have bad RAM, so either you've recently put in new RAM, knocked some RAM loose from the socket (really hard to do), or the RAM went bad (maybe).
    You might need to see a real tech.
    Upon further review, I think your MBP has a serious problem.  You need to take it to an Apple Store for repair.  If you bought it within the last 12 months, you will be able to get warranty service, as long as you're not at fault. 

  • .AVI file has white screen but does have sound...

    I have an .AVI file someone sent me which by using QT Pro shows just a white screen but does have audio.
    I have Perian installed and it didn't help with the white screen. I have opened it fine in VLC player, and a couple of other media players but my issue is that I want to import the AVI file into iMovie so I can make it into a DVD. However, if I import it into iMovie, it will be the same white screen with audio.
    I have searched the web far and wide to find a solution and most are saying it could be only viewable in QT on a PC of all things.
    Is there any components out there which will help me with this problem? Any other suggestions?
    Any help would be greatly appreciated.
    Regards,
    RB

    But when I selected the problematic AVI file it too appeared with a white screen w/sound in MPEG Streamclip. So I realized it wouldn't help me either.
    A white screen usually means the selected video codec is not compatible with the actual file. Normally, I would run a conflict test. Based on your previous posts regarding the compression formats in use and the video codec attempting to perform video playback, my first guess would be that the Perian component is trying to decode a DivX (possibly v5) file. I would probably either temporarily remove the Perian component and see if the AVI file plays or remove and then replace the DivX component (if the latest one is already installed) and see if this changes the component access order so DivX is called for video playback. If you have an older DivX component installed, there may be a conflict issue. (Remember to close QT while removing/replacing components so the list will be re-initialized before making a playback test.) If all else fails, try posting a sample file so we can see if the problem can be duplicated on other systems/configurations.

  • My new iPod touch has a white screen and does not reset

    Just bought a new iPod touch and I got a white scree and cannot turn it off. I have tried reset via the power and home button but still have the white screen.

  • 5th Gen iPOD has white screen and beeps when center and menu button is held

    My ipod was perfectly fine until I downloaded iPod Updater 2006-01-10...now, my ipod has a white screen, won't turn off (white screen stays on) and when I hold the center and menu button down, it does a 3 syllable beep. I've done the switching the hold button back and forth; resetting my ipod; restarting my PC; un-installing and re-installing both the itunes software and the ipod updater and still no working ipod. I am atleast trying to restore it to factory settings, but, I get an error message on the iPod updater screen. Can anyone help? Thanks!

    everybody listen to babara hall, genius, it takes a while but reset it one more time using menu and selct and while its off for a few seconds push selct and play/pause, hold it for a long while, then let go and you'll see the apple logo and everything will go back to the way it was before.
    p.s. thank you so much, ipods working great now, glad someone knows what there doing instead of apple,lol

  • 6th gen ipod nano has white screen and won't go into disc mode

    My ipod nano has a white screen - it will play music, and it is recognized by itunes. It won't enter disc mode. I can't seem to find any other helpful steps to follow online other than put it into disc mode and restore it via itunes. When I attempt to put it into disc mode holding power/Vol down together the screen will turn back, but when I then hold down Vol down/Vol up together while the screen is dark it just goes back to white screen. I did plug it into the computer and restore it via itunes, and the screen is still white.  Any ideas?  Thanks!

    Hi LizS5,
    It sounds as if you have already done much of the troubleshooting suggested in this article, but I would suggest you work through it in order to get your iPod nano back up and running -
    iPod nano (6th generation): Hardware troubleshooting
    http://support.apple.com/kb/TS3474
    Specifically -
    Try putting the iPod into disk mode:
    Reset the device (press the Sleep and Volume Down buttons simultaneously until the display turns black—about eight seconds).
    When the display turns black, hold down the Volume Down and Volume Up buttons simultaneously until the device enters Disk mode.
    While the device is in disk mode, sync it to iTunes and try to restore.
    And if the issue is not resolved -
    My issue is still not resolved. What do I do next?
