Video distortion on cold Macbook Pro but not on warm one

Hello,
my mid 2010 Macbook Pro shows a very weird issue lately.
When i boot up from a cold state (physically cold like first boot in the morning) it shows some
screen distortion and hangs (mostly at the user selection screen).
Mouse is responsive but i cant click on anything.
The screen distortion is basically some kind of pattern between good and not good "small tiles"
of screen.
The weird thing is now that if i turn off and on a few times (2-3) it goes away. As soon as the Macbook
gets warm the problem disappears. It wont come back during usage until the Macbook gets cold
again.
One more thing, the distortion seems to be sensitive to physical movement of the Macbook.
That means if i shake or twist it, the distortion changes a bit. Doesnt go away completely though.
Many thanks for any suggestion what to try.

Did you purchase AppleCare? If so, you'll still be under warranty. If not, you'll have to pay for any repairs. Because it sounds as if you have a graphics card problem.
If I were you - warranty or not - I'd take the machine to your local Apple Store or an AASP and have them run extensive diagnostics. You need not pay for the diagnosis but if it is your video card they will have to replace the whole logic board which can be quite expensive.
But take it in and have it diagnosed, at least.

  • Why are some songs distorted on my Macbook Pro but not on my iPhone 4?

    I purchased the new Patrick O'Hearn album through my iPhone 4 (latest iOS) with the ITUNES app. When I got home and synced the phone with my 2008 Macbook Pro (Lion with latest patches) and began playing the album through my desktop speakers, some passages of the music seemed distorted or over-driven. At first I suspected a poor digital encoding of the music, or problems with the cable or speakers. I plugged the cable directly into the headphone jack of the iPhone and the music played perfectly, and without distortion.
    So, the problem is the MBP, or iTunes. Can anyone offer suggestions to remedy this?

    I had Sound Enhancer checked. When I removed that option the distortion was still there but was reduced.
    I played several similar songs (same artist, same levels, similar composition) that I have had for a long time and found no distortion at all. The old songs had been ripped from the CD to MP3 format or purchased as MP3 from Amazon.
    So it doesn't appear to be hardware related (MBP, cables, Speakers), but instead may be encoding (AAC) or DAC related to differences between MP3 and AAC.
    Still looking for a solution.

  • My simpletech external hard drive shows up in disk utility on one macbook pro but not my other one.  how do i fix this???

    I have two macbook pro computers.  My external HD was reformatted on one of them from a PC to MAC.  It shows up just fine on this macbook.  The other macbook, I cannot find it.  Ive tried in disk utility and Ive tried to see if it was hidden.  Cannot access it.  What can I do to make it show up?

    Mac's with OS X 10.6.4 or earlier can't read exFAT, so if it was formatted with that (or OS X Extended J) ) and the other Mac is running 10.6.4 or earlier or is even older, it can't read the exFAT format or HFS+ format, perhaps only HFS.
    You'll have to settlle for FAT32 (MSDOS) with a MBR Partiton map to be fully compatible with all computers, but you can't have over 4GB sized files with FAT32.
    You can try OS X Extended, no journaled, just for the Mac's, but MBR with FAT32(MSDOS) would be preferred. PC and Mac of all types.
    Before you change anything, remove all the data off the drive first.

  • Why does a utube video show on my MacBook Pro, but not on my iPad?

    Hello,
    My MB Pro runs Mavericks, ver.10.9.4, my iPad is an iPad4 ver. 7.1.2 (11D257), Model: MD512B/A, 64GB Retina.  Browser: Firefox ver 32.0.1
    I use iWeb 3.0.4 (601) to run my website: http://www.lakesweddingmusic.com
    On my website, I have three uTube videos, which run perfectly fine on my laptop, but one of them - the first one on the site, with the picture of a bride - refuses to load on my iPad.  I have used exactly the same method for importing the HTML code for all the videos, yet the first video just will not appear on the iPad for some reason.  I have no idea why this should be the case.  When I first uploaded the video to uTube and imported the code to iWeb, it worked for a while, but now - nothing.
    Any help would be most appreciated.

    Apparently my first response was off in left field.  The DVD player has its own code.  My recommendation is to change the code when it asks.  It is possible that the disks that play correctly are region-free and the ones that don't have a region code.  If this does not work, you still have four more changes available; you won't be stuck with the new code.

  • I keep getting kicked off of my wifi with my MacBook Pro but not with my IPAD?

    I keep getting kicked off of my wifi with my MacBook Pro but not with my IPAD, what do I do?

    Hi, mmayers.
    Sometimes a simple power cycle of the router can correct the issue that you are experiencing.  However, the issue could be a little more complex.  Wi-Fi routers need adjustments to settings periodically for optimized performance with the constant progression of wireless device technology.  Below, I have included two articles.  The first article will cover basic Wi-Fi troubleshooting.  The second article covers the recommended settings for current Wi-Fi access points.

  • USB Card reader works on MacBook Pro but not Mac Pro

    I have a random "All-in-1" card reader from Quantaray. I'm trying to mount my CF card because it takes forever and a day to import HD video directly from my Canon 5D Mk II.
    It works on my MacBook Pro (Mid 2010). Both computers are running 10.6.8. All I have to do is plug it in and it appears on the desktop on my Macbook. But not on my Mac Pro.
    I've already tried resetting the PRAM and SMC. No dice
    It shows up in the System Profiler under the USB High Speed port as a usb card reader but I can't find it anywhere; not even in Disk Utility.
    Any ideas?
    Thanks

    jaypie77,
    First, you must identify the application that created the file. If it truly was Macromedia Flash, fine. Once you know which app created the file, make certain that the same application exists on the Mac Pro. If it does, set the file to open in that application: Open a Getinfo window for the file, then use the "Open With..." dialogue to choose Macromedia Flash (or the correct application) to open the file.

    4. Turn on your iPad and test print.

  • Canon printer WORKS in MacBook Pro but NOT in Chrome/ iPhone 6 after iOS 8 update

    Canon printer WORKS in MacBook Pro but now NOT in Chrome/ iPhone 6 after iOS 8 update. The printer worked previously with NO PROBLEMS. The printer is online & connected to the WiFi, not issues.

    You probably would get better answers in either the iPhone or iOS forums. This is for Macbooks. I've asked the hosts to move it.

  • Transferred a video from phone to macbook pro but sound is not working.

    I transferred a video from my phone to my macbook pro. the transfer was successful but the sound is not working on the computer, totally mute. the video is playing on quicktime player. the computer sound is on. the video was working fine on the phone and when i transferred the video, if this makes any difference or anything, the phone's media volume was on full.
    I very much appreciate the help and feed back, thank you!

    I have this same issue and have been struggling with it for a while.  I really just need to get it into Apple Store to be fixed most likely - but avoiding the hassle and time needed to do so.
    Things I've come across:
    Something inside of the headphone jack is not right, such that it randomly thinks headphones or some other type of optical audio device are plugged in.  you will see a red light inside the jack occasionally when it happens.
    You might try doing PRAM and/or SMC reset ( http://support.apple.com/kb/HT3964 )
