HT3964 I have a white screen, nothing happens, I have a iMac. What can I do?

iMac doesn´t do anything. only the white screen , when I put it on. what can i do?

Repair/verify doesn't fix anything when you use Disk Utilities from your installer dvds or lion recovery partition?
Did you remove all additional firewire and usb peripherals?
A smc and pram reset has no effect?
Booting in safe mode doesn't work?
Try running Apple Hardware Test.

    Hello onemeeks,
    If your iPod is unresponsive, it may be best to run through the following troubleshooting assistant:

  • I dropped my iPhone 3G and now there is a white screen that will not go away.. what can I do to fix this?

    Okay so I dropped my iPhone 3G today and ever since it has been stuck on this white screen that has stripes on it. I have tried holding the home button with the up volume and the power button for a while and that didn't work. I also tried just the home button and the power button. I also tried taking it apart to see if something was loose but nothing was. PLEASE HELP I don't want to get rid of my iphone!

    Applecare+ for iPhone covers two instances of accidental damage for a fee of £49 per claim (in the UK).

    If you don't have Applecare you can usually get a refurbished unit from an Apple Retail Store cut price - though they may not have any 3 models in stock and you may be 'forced' to upgrade to a 3GS.

    … the funny thing, this article and all other profound advice been found on the net, miss to mention a very basic advice:
    first of all, a MC is clip as any other !
    … sounds perhaps a bit … too basic , but  - as an amateur like me, and using MCs almost any day - you should keep that in mind for your workflow.
    After creating a MC, which can be done in seconds!, you get a single clip in the Events browser - and you should treat it as any other clip:
    select parts of it, add it to your timeline, you can add it to secondary (for pic-in-pic for example), you can split it, shift it, nudge it, ...
    aaaand you can select a diff. perspective = camera (or mic…), without losing synch.
    I'm noticing, people spend way too much time in the multi-track timeline view of an MC, in hope, this gives them back those 'tracks' FCPX doesn't offer (for good reasons...)

  • My Ipod suddenly has a white screen and will not turn off.  What can I do?, My Ipod suddenly has a white screen and will not turn off.  What can I do?

    My daughter was playing on her Ipod Touch when the screen went white.  It will not turn off or do anything.  Has anyone else had this problem and know what may work?

    The same thing just happened to my new ipod today while i was trying to use an app. A lot of people say that it is caused by an ios update, but I let the battery on my ipod drain until it turned off.  Once i charged it, it turned on and is working normally again

    Boot from the installer disk and start again, you did backup before you started this, right?

  • The gmail stopped working in the ipad; when i touch the screen nothing happens, other apps are working

    THe gmail stopped working; when i touch the screen nothing happens, cannot use any funtion with gmail, but other apps work normally

    Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps from the tray before doing the reset
    If it is the gmail app you are using, you might also try deleting and reinstalling it. If you are using the built in iOS mail app, you can try deleting and re-adding the gmail account.

  • I am trying to download snow leopard, but with around 46 mins to go, a message appears saying, my coup is going to restart,it does but with just the apple logo,and white screen, nothing else,can anybody help? jib.

    i am trying to download snow leopard, but with around 46 mins to go, a message appears saying, my coup is going to restart,it does but with just the apple logo,and white screen, nothing else,can anybody help? jib.

    I think we need more clarification.
    What do you mean by "download"? Only updates are available as downloads, the System software has to be installed from a DVD.

  • On boot up, just white screen with logo and windmill.  Forever! Can't get out.

    On boot up, just white screen with logo and windmill.  Forever! Can't get out.

    Backup in case your disk is failing.  (Post back if you need instructions on how to do that w/o booting OS X.)
    Start up in Safe Mode;  http://support.apple.com/kb/PH14204?viewlocale=en_US
    If it boots reliably in Safe Mode then it is probably a software issue.  Post back for more instructions.
    Reset PRAM: http://support.apple.com/kb/PH4405
    Boot in Recovery Mode.  (Hold down the Command (⌘) and R keys as your computer restarts.)  Run Disk Utility.  Click on the upper left system disk icon.  Does S.M.A.R.T. report “Verified”?  If not the disk is failing and will need to be replaced.  Click on the icon underneath and indented to the right, usually called “Macintosh HD”.  Repair Disk.  It should finish normally with a green OK message.  If it does not try to repair it again. 
    If it will not finish with the green OK message then use Disk Utility to erase the drive and then reinstall OS X.  (Be sure you have a backup before erasing the disk.  Post back if you need instructions on how to do that.)
    If it repaired all errors and is still not booting normally, reinstall OS X.
    If it is still sick after all these steps then the disk probably needs to be replaced or it could be a disk cable.  You replace these inexpensively and fairly easily yourself or take it to an Apple store for them to do it for you at a higher cost.  If it is still under warranty or AppleCare have Apple do it for you for free.  You may want to have Apple check the health of the system and disk before repairing it yourself.  Post back if you need instructions on replacing the disk and/or testing the disk cable. 

  • HT2452 White screen at startup and stays?? How can I get past this?

    White screen at startup and stays?? How can I get past this?

    Safe Boot is perfoming a disk integrity check and repair process which may take a long time. Let it complete, though if the startup disk requires repair to begin with, it is likely already in a failed state.
    If the Mac eventually starts, take that opportunity to back up your important data if you have not already done so. It may be your last.

  • I want to update my applications I keep on entering the password and it keeps asking me about it and again I enter it and nothing happens although it is correct I can download new apps but can't update the old ones

    I want to update my applications I keep on entering the password and it keeps asking me about it and again I enter it and nothing happens although it is correct I can download new apps but can't update the old ones

    Then you will need the password for the old account in order to update the app.
    apps are tied to the apple id that was used to purchase the app.

  • I just got one of the new iMac.  following the on screen instructions to do migration assist.  I guess it connected via wifi to my old iMac.  now it seems to have stopped.  what can I do to not mess it all up?  how long will it take on wifi?

    I just got a new iMac.  was following the onscreen instructions to do migration assistance and I guess it connected to my old iMac via wi fi. It never instructed me to connect via firewire.  Now it seems to have stopped.  what can I do that won't completely mess it up?  how Long will it take to do over wi fi?

    Your new iMac does not have a Firewire port so you ned this adapter:

Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Reinstalling OS X Without Erasing the Drive
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list.  Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
    Reinstall OS X: Select Reinstall OS X and click on the Continue button.
