  • White Screen after start up chime and Apple logo, any common issues/reasons?

    Hi all,
    I have a 2011 quadcore i7, 4GB RAM MacBook Pro which has recently and suddenly developed this annoying fault. A perminant white screen after the Apple logo and spinwheel. I have removed the hard drive (from my early 2011 MacBook Pro) and did a clean install of Lion (10.7) and I know the harddrive is fine and functional as my Mac Pro is able to boot from it and works perfectly, put the same drive back into the MacBook Pro and same, start up chime - Apple Logo - Flash, screen stays white. So its not Harddrive and most likely not a software problem (as the drive has been whiped and OSX reinstalled.) Any thoughts that it may be a bust motherboard or graphics card?
    Already tried:
    Safe Boot
    Single-user Mode
    Verbode Mode
    Resetting the NVRAM/PRAM
    Wiping and installing OSX
    Disc recovery
    Internet Recovery
    Many thanks in advance

  • Starts normally, white screen after start up

    I connected it through HDMI cable to my TV and still, there is a white screen on my TV as well. It's a G61-409CA

    Some windows files are corrupted or it contains a virus.
    Try entering safe mode:

  • White screen after start up

    When is switch my machine on my display works fine, i pop in the password n then its white i tried pressing "cmd + option + escape " it shows no finder so I'm guessing its the finder problem as it wouldn't load . Is there a way to get the finder back to working conditions ? .
    I tried disk
    Utility but pressing "cmd + R " during start up it says my hardrive is ok .
    Please help

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
         a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 10
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 11
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 12
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • TS1587 Hello, I downloaded an ntfs systemfile from tuxera and used it to convert a usb stick, my imac froze a while after so I turned it off the on and now I have blue vertical lines on boot up and the a white screen with lots of tine blue symbols, need h

    Hello, I downloaded an ntfs systemfile from tuxera and used it to convert a usb stick so I could put more than the fat32 4gb on, my Imac froze a while after so I turned it off the on and now I have blue vertical lines on boot up and the a white screen with lots of tine blue symbols after, mouse pointer moves but thats about it.
    Have used R and cmd to get a menu up but once I choose one of the four options my mouse is rendered useless and I cant get any further, have downloaded, to another usb stick recovery disk assisstant and am trying to use that in conjunction with the lion option on the previously mentioned screen, computer was responding really slowly and has now frozen on the terms of software license agreement (maybe the last hurdle!) can anyone pleeeeeease help!!!!!??????

    It's likely that the boot drive is failing, or that there's some other hardware fault. Run the Apple Hardware Test.

    Even if the test is negative, you should make a "Genius" appointment at an Apple Store to have the machine tested more thoroughly.

  • HT201406 i have a frozen ipod touch the screen has multicolored vertical lines and is non responsive any ideas?

    i have an i pod touch which appears to be frozen it has multicoloured vertical lines on the screen and is non responsive has anyone had the same probs

    If that does not work:
    Try:
    - iOS: Not responding or does not turn on
    - If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • I have vertical lines when printing even after changing cartridges.

    I have vertical lines when printing even after changing cartridges. There are no lines when copying, faxing or scanning, only printing. I have cleaned the glass, scanner and even dusted where the toner cartride slides in.  Any suggestions?

    Sorry but I have worked on laser printers for over 20 years and never encountered your issue.  That is of course if you are explaining it correctly.  When you make a copy to be printed or print a reports page from the printer or send a print job to the printer, if in all these cases you get the line, then yes the issue is either the toner cartridge or the fuser.  If you make a copy to be printed and it prints without the line (Put original in adf, press copy button and print should come out), then you have one weird unit since it does not make sense since the print formatter on the unit whether making a copy or printing from the computer or unit itself uses the same hardware.  Now to test if the printed copy has a line then just put a sheet of paper on top of the feed tray and do a self test from the printer.  When the back edge of the paper enters the printer, quickly open the toner door to stop the printing.  Remove the toner cartridge and look at the image below.  If the defect is present the toner cartridge is the issue and if the image below does not have the defect, then the fuser needs to be replaced.  Best I can do.  Good Luck.

  • I have coloured vertical lines about a quarter of the way from the left of the picture when using my apple tv 2. Anyone got any idea what is causing it. Have done a reset but still same. ATV2 is only a month old.

    Just to make sure, try a different set of cables. If the problem persists, have the unit replaced by Apple.

    Howdy carliosa,
    If your iMac is not starting up normally you may need to do some checking to make sure things are working correctly. I would suggest starting with the steps in this article -

  • I have red and green vertical lines on my screen

    I have two red and one green thin vertical lines on the screen of my iMac. Is there anything I can do or do I need a new graphics card, or God forbid a new screen?

    What model iMac? Could be a failing video card but maybe not. Is it that way on every screen, startup to shutdown, any time the screen is lit?
    Do you have an AASP nearby? Time to have an estimate made. Fixing it will likely be very expensive.
