iMac 27 "5K retina 3.5 ghz has left half of the screen is black right is normal

My iMac (retina 5K, 27 inches, end of 2014) 3.5 GHz Intel Core i5 did twice the same. The left half of the screen is black. All the right side works to the login screen.

Someone at - it ideas? The last time this happened my hard drive has failed.

I called AppleCare, they said I should have donee that reset a SMC and rest of the STROLLER instead of restarting it. (I'm not convinced that the man knew what he was saying because the screen was frozen at the connection). He said I should wipe my hard drive and reinstall the OS. Then if it happens again, I could call for help.

The computer has been running a backup time machine during this period. I heard him running. The last time this happened my hard drive has failed.

You have any ideas?

John,

Have you tried all troubleshooting such as resetting the PRAM or the performance of the Diagnostics of Apple? If this isn't the case, that is where I would start. If you get anywhere with either of the people, then you probably have a hardware problem that leads to a repair. If you bought AppleCare and the computer is still covered, then call them.

    P.S. I noticed the left hinge connecting the screen with a keyboard part is a little loose... And screen resolution is affected is I move the screen

    PLEASE HELP ME...

    It's the material. Can you connect to an external monitor? If the output is OK outside then we have reduced to a bad display cable or a bad screen. Much more likely the latter.

    Try resetting your device. This will not erase your data stored on that device.

    • Press and hold the sleep/wake button
    • Press and hold the Home button
    • Press and hold both buttons until the display turns off and on again with the Apple logo on the subject.

    Alternatively, you can go to settings - general - reset - Reset all settings

    If that doesn't work, restore your device to factory settings. Please note that this will delete the data on your device.

    Take a look this Apple Support article: use iTunes to restore the iPhone, iPad or iPod to factory settings - Apple Support.

    As a final step, try recovery mode. Turn off your unit, then plug it to your computer with the hold home button. Hold down Home button until you see the logo of iTunes on the screen of your device. After that on your computer, you should see the iTunes window saying that your device needs to be restored to factory settings. Click Restore.

  • I just cleaned the gills vacuum in my desktop iMac computer and removed and cleaned where is ram and now my iMac does not illuminate and the screen is black. My external hard drive turns on and I can hear it running, but that's all. Any ideas. I'm devasta

    I thought I was doing the right thing, but now it is clear that I was not properly clean even if I was very gentle. Why the screen lights up or really light up at all. Completely black and the keyboard does not light either. Someone has an idea? Thank you

    Unfortunately, vacuums are very statically charge and their use within electronic devices is usually not a good idea. It is very possible that the discharges of static electricity has damaged your iMac.

    I hope that you unplugged the iMac before cleaning. Make sure that the iMac is reconnected.

    Hold the Apple store nearest to the assessment of the iMac.

  • My Macbook has big bumps and the screen does not close.  Can it be fixed?

    Previously, a fallen friend my 2013 non-retine Macbook Pro 13 inches on one floor wood to six feet in the air.  After the landing, my laptop proceeded to bounce back, and when I picked it up, he had a gargantuan tooth in the DVD player (see these images: http://imgur.com/a/CDg3R). I also noticed that the screen closes nor completely, even when I press on toward the bottom.  Y at - it repairs I can do?  Or is it better for me to buy a newer, more stylish mac?  What is the least expensive?  Thank you!

    Bend it back... with care. We could break it. Even if you do not, the result will be ugly... but it will be a character.

    Or is it better for me to buy a newer, more stylish mac?

    If you want to know whether it pays to pay Apple to fix it, the answer is that such a remedy will be almost certainly economically unjustified. I suggest Flex things up, so that you can continue to use it.

  • Qosmio G10 has vertical lines on the screen

    I have a G10 which I use for the last 15 months since I bought it.
    However, there are now 4 vertical lines on the screen, 2 Purple (magenta?), 1 yellow and 1 cyan. Other than these lines there are no other problems, it never fell down or something like that.

    The lines are still there, they do not change in any way and are always in the same place. They appear on the screen at first power up, before the Qosmio logo lights up.

    They have not all appear at the same time, they all appeared individually in the past two months. I've seen the last of them disappear briefly, then stay on.

    I guess that my screen is dying slowly, I guess to be an expensive item.

    Any advice thrown my way would be greatly appreciated!

    I took a picture of the screen you will find at:

    http://www.imagebucket.NET/images/lldata/displaylines.jpg

    Note: the photo was taken with Media Player full screen on a black image, just to clearly show the lines)

    Hello

    I suggest you connect an external display to check if it's a graphics card or a display problem. If cela pipes appears also on the external screen then it could also be a problem with the graphics card.
    If these lines do not appear on the external display while the display of the laptop has a malfunction.
    However, this does not change your situation. I recommend you contact the Toshiba ASP to solve this problem.

  • How can transfer emails to another account, but only at certain times of the day (after that reception has left and before the start of the next working day)?

    I run a private school. The receptionist left to 1800 and begins at 0900 the following day.

    How to receive email between 1800 and 0900 to my private account, but not the e-mail during business hours?

    I guess that you have a computer with Thunderbird installed.
    I imagine that you have a profile with an e-mail account that is used for the activities of the private school and the receptionist has access to this email account, if you don't want the receptionist to see your personal emails.

    I would approach this by creating "User accounts" on the computer.
    Thunderbird would work in all user accounts.
    A standard user account could be used by the recepionist which would profile with business e-mail address account.

    The main account of the "Admin" user, accessible by entering a password, have your profile and your personal email to your personal email account.
    Then you can connect to your user account, open Thunderbird and access/download your emails whenever you want. Output of Thunderbird and your user account when you are finished. The receptionist will not have access without knowing your user account password.

    Alternatively, if you use the same user account:
    If you have created another profile and added a new existing for your personal email address, then after 1800hours e-mail account, you can leave the profile used for the account of the company and open the profile with your personal e-mail account to download emails. By offering you this profile nearby and open the profile of the company before 0900hrs, then it works as expected.
    If you use the same user account, it is possible, if the receptionist knows how to open your profile and read emails. Thunderbird password manager may be used to protect access to your e-mail account password, but not stop playback of downloaded emails.
    So why it is preferable to use "User accounts" as described in the first option.

    Then perform the following steps:

    • Click on the orange top left Firefox button, then select the 'Options' button, or, if there is no Firefox button at the top, go to tools > Options.
    • In the Firefox options window, click the Advanced tab, and then select 'General '.
