Horizontal blue lines are appearing on white screens.  Can I fix this?

Horizontal Blue lines are appearing on my screen whenever the background is white.  Is this something I can fix?

Hello Eliza,
Thank you for the details of the issue you are experiencing with your display on your MacBook Pro.  I definitely understand your concern with this.
I found an article with steps to troubleshoot issues with displays.  This article is for internal and external displays, so you can skip any steps referring to an external display.  I recommend reviewing the full article, but this step specifically stands out to me:
Reset the system
You can reset the Mac's parameter RAM and SMC.
You can find the full article here:

Thank you for posting in the Apple Support Communities.
Best,

  • Many of my recently uploaded photos are horizontal when they should be vertical, and vice versa.  I've corrected all these on my laptop but in my iPad and i Phone photo streams they are still mixed.  How can I fix this?  Thanks.

    Add the corrected ones to your PS - PS contains only what was added to it - changes made are not applied to the PS - you have to re add the updated photos

    First, try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."

  • (Yellow) Highlights appear black. How can I fix this?

    Today I woke up to find that I can't read the highlighted parts of my PDFs because they suddenly appear black. I have a Mac. Any suggestions as to how to fix it? Many thanks.

    Hi Anubha Goel. Thank you for your response.
    No, the document was not sent to me, and it happens with all my PDFs.
    MAC OS: 10.6.8
    I already tried what you suggested. Still looks black.
    Another weird change: when I select a line or two, instead of the selected
    part looking blue (as it did before), now it looks black and the letters
    look orange.
    Thank you.
    Regards.

    You have not provided any useful technical information like system specs, error messages or whatever. We don't even know your exact product version.

    Hi, my wife uploaded new fonts to her macbook and now can not see any writing on her screen, can I fix this?
    System fonts deleted accidentally. Does anyone know how I can fix this please?

    Thanks Mike,
    Absolutely right. I restarted in Safe Mode. This enabled me to see the actual text on the screen. Then I backed up. Then reinstalled. All fixed.
    Thanks again,

    You don't in the condition it's in. You will either have to get the phone replaced by Apple or pay a 3rd party to repair it.
    there seriously should be more than two ways to solve this other wise apple is useless and we will never buy another apple product.
    Seriously? It's physically broken!

  • Video clips imported from an iPhone into iMovie ver 6 are rotated 90 degrees; how can I fix this or avoid it?

    Video clips imported from an iPhone into iMovie ver 6 are rotated 90 degrees; how can I fix this or avoid it?

    iMovie works best with uncompressed audio. If your track is MP3 or AAC, you may get better results by converting your track to the AIFF format and then using that in iMovie.
    You can do this in iTunes. Go to iTunes/Preferences and click the General button. On the General page, click the Import Settings button. Choose IMPORT USING: AIFF ENCODER.
    (note: remember what you changed it from so you can change it back later, before you import another CD)
    Now, in iTunes, select your track. Then click FILE/CREATE NEW VERSION/AIFF VERSION.

    Just thought I'd let you know.  Our suspicions were correct, it was the OS. After I installed Snow Leopard (10.6.8) all the problems were corrected.  I also updated the RAM from 1 gb to 6 gb. The mac is working all around better. Sorry it took so long to get back to everyone. My superdrive had pooped out. Rather than replace it I got an external drive from OWC connected with firewire 800.  So far everything is running very well, as far as I can tell this external drive is better than the original superdrive. My superdrive has always acted funny, infact I returned the first mac I got after a week because its superdrive was also malfunctioning. Anyway, all that to say everything seems to be fully functioning again.

  • I can not perform software updates or download any programs. They appear in the download box as images that are not recognized. How can I fix this?

    I can not perform software updates or download any programs. They appear in the download box as images that are "not recognized". I thought maybe my antivirus software was setting up a firewall, but I have disabled it, so that's not the case. Any suggestions as to  how I can fix this?

    If the downloads are gone, it's possible that Windows is removing the downloads based on security policies set in IE. I realize that sounds strange, but it's related to Firefox's feature of submitting downloads to your virus scanner and marking them as having come from the internet.
    To test this theory, you could try disabling the scan feature. I assume you have good "real time" antivirus protection which checks every file saved to your hard drive. (If not, you really should get that, and you can use Microsoft's free [http://windows.microsoft.com/en-US/windows/products/security-essentials Microsoft Security Essentials] for now until you have time to review all the available choices.)
    (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
    (2) In the filter box, type or paste '''scan''' and pause while the list is filtered
    (3) Double-click '''browser.download.manager.scanWhenDone''' to toggle its value.
    Firefox now should ignore Windows' download security. Does it change how Windows handles the file?

  • Why are my photo images pure black?  New photos uploaded are not viewable and are 100% black.  How can I fix this?

    Recently my photo images are 100% blacked out and can't be viewed at all.  Also, upon editing a few photos Aperture got bogged down and then image turned 100% black.  I am now aftraid to open or edit any photos, and fear I have a virus/bug that could be damaging my photos.  What can I do to fix this?

    Hello hjerge,
    After reviewing your post, I have located a piece of information in the Aperture manual that can help in this situation:

  • Links in my e-mails are not working. How can I fix this?

    Several e-mails that I opened today that had a link to go the another site Firfox did not allow this to happen. I clicked on the link and nothing happened, it when nowhere.

    If the AOL account is grey out that means you are using that account as the primary account on the phone; when you setup the phone for the first time it asks for an email address, this is the primary account and cannot be deleted without do a hard reset.  To do a hard reset go to setting tap about and tap reset your phone.
    I would recommend using an Outlook/Live account instead and then use the AOL as an email account only.
    No need to shutdown apps the phone does great app management but if you need to and if you are running Windows Phone 8 just hit the back arrow till you get to the start screen.  This means that all open apps are closed.  If you are running Windows Phone 8.1 tap and hold the back arrow and you will see all the apps running and you can hit the (X) to close them.

  • After upgrading to iOS 5, my synced photos are not alphabetical.  How can I fix this?

    I have around 2,000 pictures in my camera roll and around 4-5 albums.  Before, all my pictures were sorted alphabetically, but after this upgrade each album's pictures seem to be in a random order.  Any ideas on how to order them the same way they are on my PC?

    I'm afraid you'll have to wait until both Apple and the makers of your games/apps upgrade to new versions.
    Apparently there are still some issues with iOS7 that are being dealt with and the same with some apps.
    As for going back, I don't think you will be able to get this information from these forums...
