  • I reset my iPod touch, now the logo blinks on and off screen with no response

    I reset my iPod touch, now the logo blinks on and off screen with no response

    Try:                                               
    - iOS: Not responding or does not turn on           
    - Also try DFU mode after try recovery mode

    - 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.
    - Try another cable       
    - Try on another computer                                                       
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • Why does my image blink on and off when using selecton tool

    why does my image blink on and off when using selection tool

    This is due to the hardware acclerated drawing not working properly because your graphics hardware doesn't support it right. This is usually resolved by updating the graphics driver to the latest version. If this is not possible, turn off OpenGL in Preferences --> Performance.

  • My iphone went dead and now has the apple logo blinking on and off

    my iphone 4 went dead and now has the apple logo is slow blinking on and off when it's plugged into my computer. I cannot stop it. Tried a hard restart but nothing happened.

    Morning blgarratt,
    Thanks for using Apple Support Communities.
    If it is showing the Apple logo with no progress bar or a stopped progress bar, for over ten minutes.
    For troubleshooting on this, take a look at this article:

    Hope this helps,

  • Display blinks on and off

    I'm using two displays with my G5. The primary display recently started blinking on and off when I used any "busy" web site, meaning a site on which images constantly change or text automatically updates. The problem occurs in both Firefox and Safari, although it seems to occur more frequently when I use Firefox.
    There's no issue with the secondary display. If I move the browser window to that display, I can browse all sites without problems, regardless of the browser I use. Also, when I quit the browser on the primary display, the blinking stops; it doesn't occur when I use other applications.
    A self-test of the primary display checked out OK, and the problem persists even though I replaced the monitor's cable. Coincidentally -- or not -- the problem occurred after I installed Leopard on the Mac.
    Any ideas about what's happening or what I can do to diagnose?
    Thanks.
    David

    Thanks for the response.
    The problem (which I just noticed occurred in Entourage also) resolved after I reversed the monitor connections. I then reversed the connections back to the original configuration, and the problem has not recurred (at least so far), either in the dual-display or single-display configurations.
    The only thing I can think of that may have had an effect is that the primary monitor, connected digitally, ran an auto-reset function after I switched the connection to analog.

  • Desktop icons blink on and off; computer won't boot

    I was recently trying to view a quick time file on a dvd when I got the message that some components may be missing to view the file. I downloaded the components from Avid and put them into my quicktime folder (Library>>>Quicktime folder).
    When that didn't work, I removed the older component that had been in the folder and tried to to view the DVD again. This time I was unable to even open Quicktime. I tried to return the "old" component back into the Quicktime folder, but kept getting an error message. Something along the lines of "an unexpected error occured."
    I then attempted to reboot the computer. That's when the trouble really started.
    My computer now gets to my desktop; all the icons blink on and off, and then the computer seems to try and try to start. I assume that the component I removed was in the start up sequence, but a) I don't know for sure, b) I, of course, can't get on to find out, and c) even if that is the problem, I don't know how to fix it without getting that error message.
    Has anyone experienced this problem? Any thoughts? All assistance will be HIGHLY appreciated. Thank you.
    LHT

    Restart your machine with the Command and S keys held down, and enter the following commands:
    mount -uw /
    mv /Library/QuickTime/ /Library/QuickTime_old/
    exit
    Your computer should then continue the startup sequence; if it finishes starting up, the components you installed were responsible for your issue. My own /Library/QuickTime/ folder is empty, so the folder doesn't contain anything critical.

  • I am trying to download a variety of files and when it is finished, the Mac freezes up and the task bar continues to blink on and off. I have to go into Firefox and actually quit the application to continue. Any help is very much appreciated

    I am trying to download a variety of files and when it is finished, the Mac freezes up and the task bar continue to blink on and off.
    I have to go into Firefox and actually quit the application to continue. Any help is very much appreciated.

    are you backing up files, or doing a Time machine backup, either way, the Time machine will STOP when finished and show "last backup at XXXXXX"  meaning its done...... OR if when transferring files, it will show a progress bar on your desktop and vanish when files are copied.
    Open up the Hitachi drive (your G drive is made by Hitachi, and the best made by the way).....and see if the files are there.
    a MORE VISUAL way is to open the hard drive file, and drag and drop files INTO the Gdrive and you can see them visually be copied there as you do it.
    To see your HD on your desktop GOTO  FINDER......PREFERENCES....then GENERAL TAB.........check the box marked HARD DRIVES.........then your Gdrive will appear on your desktop........open it from there,  and DRAG and drop files from anywhere INTO the Gdrive....... easy visual way to see the files being copied into the Gdrive.
