Strange flickering on MBP screen as folding shut

I'm hoping someone can explain this, or at least let me know if they have the same problem.
I have noticed that as i am closing my macbook pro screen (not shutting down the mac but folding shut) that the screen does some funny stuff. When the screen is closed past about 45 degrees the screen has issues and any dark colours (mainly blues and blacks) seem to flicker a red-ish colour.
i dont know whether this has always been happening, however i havent noticed it until very recently ad had the thing for about 6 months.
its very strange and can only guess its prob with the graphics card driver or something. i have searched the forum and cannot find any posts relating to this so i hope its not my mbp!
any advice or info would be greatly appreciated.
thanks

I have also recently noticed the same problem with my MacBook Pro, just in the last month or so. I have only had the computer for 4 months. I have also noticed the same problem twice in the last week when I opened the lid of the computer to wake it from sleep. In both of those instances, horizontal flickering lines were present for about 10 seconds before the screen returned to normal. I'm concerned that it could be a problem with the screen connection to the base of the computer since it seems to happen when moving the screen. On the other hand, I have not noticed these same anomalies when using Windows XP through Boot Camp.
I also plan to take the computer in to the local Apple Store following the holiday season since I'm also having a problem with my superdrive, I will bring it to their attention then. In the meantime if anyone else has been having this problem and has spoken to Apple about it, please enlighten us.
Thanks.

  • Strange flickering lines across screen, opening Photobooth makes them go away?

    Hi everyone,
    I've been having a very strange problem with my 2011 Macbook Pro 15" for quite a long time now. It's basically flickering lines across the screen, and the screen 'folds' in on itself, squashing the display vertically and stacking them on top of each other. Sometimes it's terrible, sometimes it's bearable. Sometimes the screen goes completely black. It's super weird. Here's a photo I took my phone, as I screenshotting shows nothing out of the ordinary:
    The really really weird thing is that when I open Photobooth, as in the apple webcam program, the problem completely goes away (until I quit it). I had hoped this was a software issue, so I backed up and formatted my hard drive and then installed a fresh copy of OS X - and the exact same thing happens! I barely made it through the system setup!
    I beg, someone help me!

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac. 
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. 
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    Launch the Terminal application in any of the following ways: 
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) 
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. 
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click the line of text below to select it:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit 
    Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open. Post the contents of that window, if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    { sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook; } | open -f -a TextEdit 
    This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3
    launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}' | open -f -a TextEdit 
    Step 4
    ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null | open -f -a TextEdit  
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 5
    osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit 
    Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

  • MBP strange flickering blocks of multi-coloured lines on screen

    Hi
    over the past few weeks when awaking from sleep my MBP 13" (mid-2012) has had this problem <a href="http://s1204.photobucket.com/user/sjwhite26/media/IMG_0035.jpg.html" target="_blank"><img src="http://i1204.photobucket.com/albums/bb404/sjwhite26/IMG_0035.jpg" border="0" alt=" photo IMG_0035.jpg"/></a> i.e. blocks of multi coloured lines flickering on the screen.
    You can use the machine, but its incredibly annoying and and reboot gets rid of it.  My issue is that it is happening more and more.  I also have the issue when the MBP won't always wake from sleep when using the mini display port attached to my screen.  This is viewable on the laptop's native screen as well as the dell screen.
    Any help would be appreciated.  I've tried all the PRAM etc resets.
    Thanks

    Let the battery full drain. After charging for at least an hour try again. Include thises suggestions as necessary.
    iOS: Not responding or does not turn on
    If still problem time for an appointment at the gensiu Bar of an Apple store.

  • Strange scatches on the screen (mbp bought 3 weeks ago)

    Welcome to Apple Discussions!
    It's kind of hard to see what these are from the picture you linked, but I would definitely bring it to Apple's attention on a brand new Mac.
    Good luck!

  • My late 2011 15 inch mbp screen shuts down and don't turn on

    My late 2011 15 inch mbp screen shuts down and don't turn on. Sometimes goes down after it gets in the sleep mode but another times it goes down when i'm working on it. The battery lights and the magsafe light still work but the screen doesn't respond, i have to shut down the computer and only after a couple of tries to turn it on i the screen wakes up. Also, sometimes when i turn it on the screen gets fragmented, like in the image. Does anyone have any solution? thanks.

    Please make a Genius Appointment and take it in for service.

  • MBP 13" late 2011. when I turn it on it goes to an update screen then just shuts down

    Lately I had problems  when I recharged the battery, charging is constantly interrupted... And now, when I turn it on it goes to an update screen, then just shuts down.  O.S: MAVERICKS
    PLEASE  HEEEELP!
    P.D: Sorry for my english.

    LaCalle,
    you can try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, select the First Aid tab if it’s not already selected, then press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it get past the update screen now?

  • Strange mark on my screen

    Just noticed a strange marking on my screen when it is turned off, I've tried to clean it off with various products, but it appears to be grease-proof.
    Anyone know what it might be or how I might go about getting rid of it?

    Take the MBP to your local Apple Store or an AASP.  Let them deal w/it.

  • MBP Restarts and or shuts down when you close it.

    When I close the my MBP and open it the screen is black only when I press the space bar or power button my MBP either restarted or shut down. Is there a way to fix this and is this a normal thing?

    Hello,
    Try resetting the SMC Controller (http://support.apple.com/kb/ht3964), or the NVRAM (http://support.apple.com/kb/ht1379).
    Hope this helps!

  • Screen goes black, shut the lid for a few minutes, open the lid the turn on chime comes on and the screen comes back to life. The computer itself has continued to update just no screen. After a few minutes goes black again. Is logic board going bad?

    Screen goes black, shut the lid for a few minutes, open the lid the turn on chime comes on and the screen comes back to life. The computer itself has continued to update just no screen. After a few minutes goes black again. Is logic board going bad or graphic card issue? Trying to decide if computer is worth repairing as it was made in 2007.

    It does sound like you might have a faulty video connection. See if you can make a Genius Bar appointment at your local Apple Store.

  • Using Cinema Display with mid-2010 MBP, post-Yosemite:  corrupted MBP screen

    For a couple years I've been using a 27" Cinema Display attached to my mid-2010 MacBook Pro 15".  The dual-display setup works great for my home setup.
    However, since upgrading to Yosemite, the MBP display often completely corrupts and reverts to complete gibberish, with fragments of the UI and desktop littered all about the screen.  Dragging a window over to that screen usually "redraws" it sufficiently enough to keep working, but soon the problem re-appears.  The screen of the CInema Display (my main working area) never corrupts, only the MBP screen.
    My setup worked great in Mavericks, but something in Yosemite isn't driving both displays properly.  Can anything be done, aside from downgrading to Mavericks?
    Andy

    I am having this exact same problem.  2010 iMac with NVIDIA GeForce 9400 256MB.  I have it hooked to a 30" display through a DisplayPort to DVI-D adapter.  The 30" is fine, but I have graphical corruption constantly on the main iMac screen.
    This all started as soon as I updated to Yosemite a couple days ago.

  • Gray screen, flashing folder with question mark

    My macbook pro was working normal in the afternoon...  I closed the computer lid and returned a couple hours later to a gray screen & flashing folder with a question mark.  When I hold the option key down at startup I only get an internet recovery mode.  I plugged in my airport time capsule and was able to boot from it.  I used disc utility check and everything checked out ok.  I used my ESET NOD32 Antivirus and it checked out ok.  Finally, I went to start up disc and restarted my computer from the Mac HD.  This also worked without problem.  Afterwards I disconnected my airport capsule and restarted the computer as a final test.  Unfortunately I am back to the flashing folder with a question mark.  What do I do?

    See:

  • Strange Spots on Glossy Screen

    Hi, I am currently using a late 2006 Macbook, it has never given me any problems and it works great. Recently I noticed that there are these strange marks on my screen. They look like the normal screen except, it is slightly brighter, they look like smudges. I have a feeling that this might be the glossy coating coming off, but I can't be sure.
    I am no longer covered under Apple Care

    Smudges? I have the same problem except i have little black dots in my screen

  • Desktop restart shows flickering black/white screen, then black. Could not restart. Anyone else with this issue?

    Have the PRAM battery looked at.  It may be all that is needed.

  • My MBP 13 does not shut off

    Hi everyone, my new MBP does refuse to shut off or restart. I have had it for less than two weeks. It gives me a message that some applicattion is running (different applicattion, depending on what i have been using). In force quit there is nothing, It looks it is not able to extit Finder. I need to shut pressing the power switch every time. I read a previous discussion but I have nothing running in backgroung, no time-machine, no peer-to-peer, no external device.
    Any clue?
    Anybody things I should try to give the machine back to apple?

    I'm trying to help my Dad; he has a new MBP and it won't shut down properly for him either. We've used the myriad of keyboard shortcuts and they work for a while and then they don't work anymore.
    I read a technique elsewhere on the web that could maybe work (No guarantees-don't hold me to this; it's just something I read by googling this topic). Turn the laptop off, unplug it and take out the battery and hold down the power button for 2 minutes - then connect the laptop with the power cable without the battery and do a few restarts - this may cure it I've read. But I can't be certain of this and holding down the power button seems suspect to me so....
