Serious video related display lock up problem

I have a serious issue when playing any video (youtube, DVD, video chat, etc.). The whole computer locks up and the video on the screen freaks out. When I say freaks out I mean it scrambles and flashes and the sound starts looping on what it playing at the time of the malfunction. Video will work for a few seconds to a few minutes before this happens. The only cure is to restart the computer because all functions are locked. This ONLY happens during video playback.
My aluminum unibody macbook 2.0 is only a few weeks old. Any help is appreciated.

Hi Simon,
I am an ACMT and the issue you have described sounds remarkably like an issue I am dealing with at the moment. Playing a DVD intermittently causes the display to become scrambled and the sound does exactly as you have suggested. I have spoken to another ACMT (Apple Certified Macintosh Technician) who also had this issue. A replacement LCD and Logic Board did not fix the issue. I am currently testing my machine with some known good ram. The GPU accesses the main ram in order to draw the image. If the ram is faulty, it could lead to exactly what you have experienced. I will let you know how I go. So far the machine has successfully navigated 3 sittings of the same DVD without issue. Stay posted.
Regards,
Ben.

  • 'Preparing Video for Display' causing render problems

    I have a DV-Pal sequence, with a few crops, burn effects and transition, so I've got a lock and render everything, but every time I do about 3 mins later a dialogue box pops up stating 'Preparing Video for Display' with a little percentage bar. Once it's 'Prepared Video for Display' (whatever that means??) all my rendered effects revert back to an unrendered state.
    Has this happened to anyone else and how can I stop it?
    Much Thanks, Matt

    Quit Final Cut Pro. Go to your Render Files folder and trash the contents of the sub-folder there that has the same name as your project.
    Next step:
    Deleting FCP Preferences:
    Open a Finder window. Set the view mode to columns:
    Click the house icon that has your name next to it.
    Click the folder "Library" in the next column.
    Find and click the folder "Preferences" in the next column.
    Find and click the folder "Final Cut Pro User Data" in the next column.
    Move the files "Final Cut Pro 6.0 Prefs", "Final Cut Pro Obj Cache" and "Final Cut Pro Prof Cache" to the Trash and empty it.
    When you have a stable set of preference files, download [Preference Manager|http://www.digitalrebellion.com/pref_man.htm] to back them up. If you have further problems, the backup can be recalled and you can continue working.
    Re-open your project and render again.

  • The sound on all of my game apps and my alerts has stopped working. Still works for Netflix, Hulu, YouTube... Anything video related. Anyone else have this problem or know what I should do to fix it?

    The sound on all of my game apps and my alerts has stopped working. Still works for Netflix, Hulu, YouTube... Anything video related. Anyone else have this problem or know what I should do to fix it?

    If you lose sounds for keyboard clicks, games or other apps, email notifications and other notifications, system sounds may have been muted.
    System sounds can be muted and controlled two different ways. The screen lock rotation can be controlled in the same manner as well.
    Settings>General>Use Side Switch to: Mute System sounds. If this option is selected, the switch on the side of the iPad above the volume rocker will mute system sounds.
    If you choose Lock Screen Rotation, then the switch locks the screen. If the screen is locked, you will see a lock icon in the upper right corner next to the battery indicator gauge.
    If you have the side switch set to lock screen rotation then the system sound control is in the task bar. Double tap the home button and in the task bar at the bottom, swipe all the way to the right. The speaker icon is all the way to the left. Tap on it and system sounds will return.
    If you have the side switch set to mute system sounds, then the screen lock rotation can be accessed via the task bar in the same manner as described above.
    This support article from Apple explains how the side switch works.

  • Apart from the lock button problem in iphone 5 the display brightness suddenly goes blank and becomes normal after locking and unlocking the iphone. The Apple service centre in India is denying to service the iphone as it was purchase in USA even thoug it

    Apart from the lock button problem in iphone 5 the display brightness suddenly goes blank and becomes normal after locking and unlocking the iphone. The Apple service centre in India is denying to service the iphone as it was purchase in USA even though the iphone is in warranty.

    iPhones do not have an international warranty.  Warranty is valid only for the country of purchase.  This is most likely because different countries require different iPhone models.  Not reasonable to expect all countries to maintain stock for all models.

  • Display and camera problems... related?

    Dear Folks of Apple Support Communities.
    Recently i have started to experience a rather disturbing issues with my screen, and that made me remember of the problems with the camera.
    I have MBP retina early 2013 and. well, it is known fact that screens on this particular model are not exactly brilliant... The same could be said about the camera, which has simply tuns of blue noise! But the screen was acting pretty Ok for some time now, there always was a minor image retention, but as i had nowhere to fix this, i had to live with it. But recently the screen started to turn GREEN! Yes that emerald shade, almost like cartoon green!!! That happened to it once before, but was not so intense, well at least i was able to see something... But the other day i was completely blown away, when i turned on my mac and i sew bright-bright green screen with absolutely no picture... Why does this happen to a £2000 product i have no clue! Now it has an uneven colour (the bottom corners are blueish, and the sides are somewhat darker).
    Is there some way to resolve it? Or should i ask for the screen replacement (and the camera with it as well)?
    I will be in Glasgow starting from september, so i will have an Apple store near by... i just don't want this to happen anymore, it is really scary.
    Many thanks . Anna.

    You should not be having those type of problems on a brand new Mac.  Did you call AppleCare about this?  If not why not?  
    You have 90 days of free phone tech support from Apple on top of your one year warranty.  Strongly suggest that you use it before you lose it!  You already missed your 14 day from the date of purchase to return your MBP for a refund or an exchange.

  • 15" Retina Display Locking Up

    My retina display locks up constantly now. It has 16gb of ram, 500gb SSD. I can view the file and run the time line but when I try to export the file is races the processor and eventually locks up. Is anyone else out there with Retina Display having the same problem? I have updated the Cuda drivers. This is Premiere Pro CC (2014) on Yosemite.
    This is insane! I'm open to try options.

    Hi Brian,
    Have you tried running through through these?
    - Sign out from Creative Cloud, restart Premiere Pro, then sign in
    - Update any GPU drivers
    - Trash preferences
    - Ensure Adobe preference files are set to read/write
    - Delete media cache
    - Remove plug-ins
    - If you have AMD GPUs, make sure CUDA is not installed
    - Repair permissions
    - In Sequence Settings > Video Previews, change the codec to one that matches your footage
    - Disconnect any third party hardware
    - If you have a CUDA GPU, ensure that the Mercury Playback Engine is set to CUDA, not OpenCL
    - Disable App Nap
    - Reboot
    Best,

  • System Freeze under 10.7 (not video related..)

    I'm experiencing problem with system freezes that are not video related.
    I've had several instances so far whereby my system freezes (the mouse cursor still reacts, but nothing is selectable) either at the Finder or the most recent when browsing apps in Launch Pad. The only fix is a hard restart. The only similarity to some of the posts re video is that my mac employs graphics switching, and I assume this is utilised when launching Launch Pad?
    Doing a hard restart also starts Spotlight reindexing my HD. Something which was only done a few days ago when Lion was installed. Doing a normal restart at this point stops Spotlight indexing when returning to the finder.
    Is anyone seeing the same behaviour on thier systems and has anyone found a cure? I've read that resetting the PRAM has helped some.

    Okay, (I think) I've found a way around the first annoyance - there's an option in Time Machine preferences to lock documents after a certain length of time. Even though I never use Time Machine (I use an easier alternative) this option still controls things. Turning off that bit (it's on bit default) made thinks better.
    I've yet to find a way around the second problem, any help will be appreciated.

  • Quicktime Video on an LCD Projector Problems & Refresh Rate?

    I'm having an issue and don't have a lot of experience with this but hopefully someone has some insight.
    When i play back video (formats including DV, DV50, HDV, PRORES422 / interlaced or progressive / frame rates of 23.98 or 29.97) in full screen using Quicktime Player (version 7.4.5) and Present (Shift CMD F) to a projector, the video plays and looks good, with the exception of during certain portions of the video (generally, with a lot of motion), i see either a flicker or what appears to be a scan line, tear, or a trace that scrolls vertically up the image. The flickering/trace is consistent with regard to a particular portion of the video, though when i adjust the refresh rate for the projector, the behavior of the flicker or scrolling trace changes (say at 60hz, it scrolls slowly up vs 85hz where i see mostly flickering/tearing of the image or multiple traces scrolling up). I've tried 3 different projectors, and every combination of screen resolution and refresh rate with no success.
    I should point out that when i play these videos full screen on a cinema display (20in or 23in) i don't see this behavior at all.
    So, i have a few specific questions:
    1. Is anyone familiar with this behavior and any solutions?
    2. The projector is connected with a VGA cable and DVI adapter. Might a DVI cable resolve the issue? Is the behavior a result of the analog input? (The cinema displays are connected via DVI and don't exhibit the behavior)
    3. If it is a projector issue, any recommendations on a good projector for presenting video played back from a computer?
    Thanks in advance for your help. If i've posted in the incorrect forum, please do direct me to the right place.
    Shane

    Just a fast reply... something to think about...
    Use 60hz, most lcd are 60hz. Check you resolution specs for the projector. If the native resolution is 800x600 use that setting if higher use that.....
    If your using the lcd as a secondary display try setting the main display to the same specs. Sometime a mismatch between the two displays can cause problems.
    Go with the lcd spec settings that's the main priority and the main display isn't.

  • Video is displaying in negative

    I have an intel iMac 17" bought in February. My kids logged on this morning to find that the video is displaying in negative, like a film negative. I first thought that maybe they downloaded some kind of skin or little app that let you change the look of the interface, but after I booted up WinXP in Parallels I found that XP was also affected.
    I then tested to see if the OS itself was defining the color-reversal by taking a screenshot, then printing it on a color printer. The color print came out normally. This suggests that the video card is the problem. If so, how do I fix it? I did check Software Update to see if there are any upgrades I need to install. The only thing that appears is the iMac EFI Firmware Update. I am going to run this now, and if this cures the problem somehow, I will post that the problem has been resolved. If not, then the problem still exists, and I would appreciate any help or suggestions to fix the problem. (This is the wife's Mac, and she ain't happy. Know what I mean?)

    Here is more research.
    After installing the EFI Firmware Update, the computer rebooted, and came back to the login screen. It was there that I realized that the login screen and background displayed just fine. I logged in to the main user, and I saw the screen initially flash with the correct colors, then immediately turn negative.
    After seeing this, I created a new user with full Admin privileges, and logged into it. The display was normal in the new user. So this appears to be some kind of preference problem, possibly a corrupt preference. But which one? Anybody know what I need to delete or change to fix this issue?

  • Need help with rendering my files..."preparing video for display."

    I don't know if I sent something to the trash folder from Final Cut, but for some reason all of my files in the timeline are unrendered, and every time I render them a message appears saying that it is "preparing video for display," and then they are unrendered again. What is this? Did I send something to the trash folder that keeps doing this? Is it a settings mode? Does it have to do with the space on my drives?

    I'm having the same problems.
    A friend of mine told me to trash the render files and re-render my whole project. He finds it some times gets rid of some of the glitches when you render along the way in steps.
    I trashed the render files and of course the project says I need to re-render which I do. I can save the project, close it, and when it opens I get the "preparing video for display". Once that's done it has nothing rendered at all.
    So I re-render, and its fine. I tab to another window and then back and it gives me the same message, completes and all my stuff is un-rendered.
    So now I have a project that every time I render it can't save it or somehow it deletes the render files if I tab out of the program.

  • FCP freezes at 'Preparing video for display'

    Hi
    I am experiencing a problem opening 2 of the fcp projects I've been working on in the last week. When opening everything seems to work fine, I see all the sequences opening, but when the 'preparing video for display' window appears it stays forever and I have to forcequit the application.
    Opening FCP without existing projectfile works fine. Also opening different older projects. Just the 2 recent projects are experiencing this problem. I still worked on them yesterday night and didn't do anything strange after.
    Also the Autosave Vault files are having the same problem.
    I've been trying to delete preference files but nothing works.
    Who can help me fixing this urgent problem. It would cost me days of work to redo the edit. And the frustrating thing is that I can already see them appearing but not touch them!
    Thanks a lot

    Dear Luca, thanks for your answer. Just before you wrote, all of sudden, after trying many times, one of the projects opened.
    I will see what happens in the next hours and write again when the same problem comes back.

  • Which MacBook Pros are safe to buy used and not recalled for video graphics/display failure (due to overheating)?

    I've had some bad luck with MacBook Pros lately. I bought a 2010 model but it was effectively a Total Loss because of a vehicle accident. From searching with Google, people have reported logic board failures. Who knows if mine would've failed, too.
    Then I bought an older 2009 MacBook Pro and that eventually failed due to the graphics chip failure. There was a recall on it but the problem occured JUST after the recall period expired. I don't have a microwave solder lying around or a proper setup to fix the problem myself.
    Now, I im in the market for a used MacBook Pro, as a gift (I can't afford a new one right now) (with the luck I have, I'm basically done with them but the person wants one).
    I've seen some 2011 models priced quite attractively, which caused me to do a quick check and find that the (early) 2011 models also have video graphic failures. I don't get it. I understand paying for the name, but the name also has to have reliability and you don't hear about video graphics failures from some of the more well known PC manufacturers..just saying.
    I'd strongly prefer to not purchase any retina models, if at all possible. I want a mechanical SATA HDD and an optical drive. I oppose proprietary components -- as I understand it, the retina models make it nearly impossible to upgrade.
    Which used MacBook Pros are safe for purchase? In other words, which ones do not have recalls or are susceptible to video graphics/display failures? I don't want to put the money down for one, only to hear it kicked the bucket and it needs service and is out of warranty.
    Thank you for your time.

  • MBP Core Duo Checkerboard display lock-up

    I am having a frequent issue with my MBP that I just received in January.
    Right out of the box, the screen froze, and I had to force the machine off.
    Now, I am getting a checkerboard display or complete display lock with any of these scenarios:
    1. Cold-boot the MBP, locks up at the login screen. Need to restart again.
    2. Awake the MBP after being asleep for 20 minutes or more.
    My dealings with customer support have been frustrating. Their latest suggestion is for me to wipe the hard drive and reinstall the O/S. This seems like a "using ashotgun to swat a fly" approach.
    I don't want to waste my time in reloading third-party apps, so before I try this, has anyone tried this approach and have it resolve their display issues?
    From what I'm reading on the Net, the logic board is the suspect, but the support folks won't listen.
    Help!

    I have been having the same problem with my macbook for months now, i have tried everything.
    I've called customer care....who frankly couldn't care less, so am taking it into the apple store today to have a apparent genius have a look.
    To be honest, i wish i had just bought a normal windows based laptop as i dont need all this hassle.
