MacBook Pro :: Screen Distortion On SR 2.2Ghz - Video Linked
Apr 9, 2010
what I imagined was a documented 8600GT nVidia issue with my SR MBP (purchased in April 2008 without Apple Care, d-oh), turns out to be a different issue altogether. The display gets distorted and it seems as if the LCD needs a v-sync controller. I have posted a video of it here[URL]. If I move the LCD slightly the distortion will go away. But it inevitably returns after a while. It gets unusable for that period of time. Oddly enough I can go hours without this problem manifesting, and then hours when this problem doesn't go away.
My recourse has been to connect an external monitor to the MBP, and it works great that way. So I am pretty convinced that it is an LCD/Cable issue as well. The Genius seemed to believe it was an LCD issue as well, something about the cable being torn or stretched or something. He quoted an amount ~$650 to get the whole assembly changed. Here's my dilemma: this is my work machine, and I can't afford to have it gone for a few days/week. Is there anything I can try at home before handing it to Apple for repair... like try and reseat the cable... I have opened the MBP in the past to replace the HDD. Should I even bother to get it repaired, if I can't fix it myself, or should I just save the money and get a new MBP?

whenever I'm listening to music or watching a video after a while the audio will drop out, stutter, or become horribly distorted. If I pause the video or music for a second then start playing it again the output will be okay for a few seconds to a few minutes then stutter again. If I leave it stuttering the output will either eventually go back to normal or just stay stuttering or muted. Once or twice I've got a 'you need to restart your computer' kernel panic error (log attached/linked to below) and twice my computer has seemingly randomly restarted itself.
I know it's not an issue with my connection as it happens on locally stored files as well as streaming media. I know it's not a hard drive issue as I've had the problem across two different hard drives (I used the Migration Assistant to swap my stuff from one HD to another, presumably bringing across whatever causes the problem). I've had it with two sets of RAM as well. It happens whatever web browser (for streaming media) or music/video player I use for local files. If I restart the computer I get a longer period of time before the stuttering starts, and it gets more frequent the longer I leave my computer running - a RAM issue maybe? These screengrabs where taken either during or shortly after the stuttering had taken place. This top output is after a particularly bad stutter: and here is a log following a kernel panic: [URL]

My two previous older macs have been perfect to me, but this new MBP I5 model is giving so many issues lately. Every once in a while, my computer's graphics (I am assuming) goes crazy, and I get this pixelated distortion that's right in the middle of my screen that's about 2"x5" on my 17" screen. This happened just earlier, while I was using Safari. However, even after closing all of the Safari windows down, the distortion will still be there, and will stay there regardless of what I have or don't have open. Logging in and out will fixes the problem, and everything goes back to normal for the mean time. Any one ever experience similar problems or know what I could do to see what's going or fix it?

I bought my MacbookPro two years ago, september 2007. In june 2009, as I didn't need the computer for some time and the warranty was about to expire (it's "two" years in the European Union, the second isn't covered by Apple, just by the physical store you buy the computer at) I thought I'd take the computer to be checked, because it had had two problems for some time: the Superdrive won't record dvds (it never did) and lately the left fan was very noisy when it turned faster.
It took a lot of time but they replaced the superdrive and the left fan. However after the replacement even though the fan is fine, the superdrive wouldn't still work with dvds, of which I don't care anymore because this is the big problem: Since then, the screen sometimes gets crazy and does as in the video I link to: [URL] It all stops when you move the screen a little. Furthermore sometimes a vertical line appears like half an inch from the left border when moving the screen. It all appears randomly................

My MB started doing this really strange thing where the screen gets all weird and distorted when scrolling. There are photos to show what's going on.
I have 4GB of OWC memory installed, but this was happening before I installed that so I can kind of rule that out.
Has anyone else had this happen, or know what causes it. I've tried all of the usual fixes like a fresh Leopard install and combo updates.

Sometimes, while watching a streaming video on my Macbook, the audio begins stuttering and tearing (that's the best way I think to describe it). Pausing and refreshing the tab is useless, and, usually, closing and reopening the browser is equally useless. This problem is not limited to just one steaming site -- issues occur on Youtube, Hulu, Megavideo etc... For about ten minutes (though sometimes longer), the audio across all programs on my Macbook does not work properly until the problem mysteriously solves itself.

I recently got my MBP and I noticed there's a issue with headphone audio distortion. When I plug in my earphone or headphone without any sound playing, there's a clear whining noise like zi zi zi sound which is really clear, sounds like old 80s radio noise. When I play the music, of course it was covered by the sound of music but it really bugs me out knowing that I cannot listen the pure sound of my music. The volume of this distortion noise would not change while I turn up or down the volume of my MBP. I asked someone professional, he said it's a famous issue of screen frequency disturbing audio in macbook pro.

Just got a new white MacBook yesterday (MB403LL/A) and have noticed, that depending on a slight change in viewing angle, pastel colors can get really distorted, even appearing as other colors, e.g., light green->gray and light orange to pink. One example would be Google calendar when editing an event. Looking at the screen in a normal position, the background appears gray, but when slumped down in my chair it looks green (the actual color). Is this a normal problem with MacBooks or could my display be defective? I took a couple snaps with iPhone that didn't turn out to hot but illustrate the point:

I've just received a brand new MBP 15 i7 with high res. matte screen. Occasionally the screen becomes sort of distorted by red pixelated shadows that seem to depend on the current wallpaper, and also to some extent stay in the background when white background windows are opened. I have posted a picture taken by camera on Flickr, since a screenshot will not capture it. The funny thing is that I can make it disappear by closing the computer and reopen it again. I cannot force it to appear again though. Is it a driver problem? It doesn't appear on the startup splash screen or on secondary monitors. Here is the photo of the phenomenon: [URL]

I have tried to add my number to both iMessage and FaceTime but it will only allow an email address to be added. I checked my Apple ID and my phone number is there. I don't know why my phone number mysteriously disappeared, it had been linked since I got my MacBook.

I recently had to erase and install Leopard. I then restored everything from my time-machine backup. The weird thing is, before, when watching streaming videos from the internet, the screen stayed at the same brightness, regardless of whether there was any mouse movement, or touching the keyboard, or anything. Now, if I don't do anything, the computer dims the screen, as if i wasn't watching a video.

I'm trying to watch a video streamed on google chrome on my second display, which is a Samsung TV connected by HDMI to my macbook pro.
However, I can't use my laptop when doing this, if I press full screen on the video no a separate window on the TV then click back onto my macbook screen the video exits full screen.

We just updated our G5s here at the lab (QuickTime and Garageband ), and now the sound output is extremely distorted and crackly regardless if its a video on cnn or a song off iTunes. Tried Zapping the PRAM and repairing permissions, even reinstalled QT from the standalone installer on apple to no avail.

MacBook Pro
Mac OS X (10.5.1)

I have a Core Duo 2006 Macbook 2ghz, 2gb RAM, running 10.6.2 and whenever the CPU is taxed for an extended period of time, chances are I'll get some audio issues. What usually happens is that the audio will stutter for a second or so, then change instantly into a heavily distorted 'bitcrusher' output. The only way to resolve this is to restart whatever program is outputting audio. So far, this has happened in both Firefox & iTunes.

I'm having issues with audio distortion on my BLUE Snowball mic. This happened in GarageBand on my old MacBook running Leopard as well as my new MacBook Pro running Snow Leopard. I've tested mics, cables, and USB ports. Nothing is consistent.
I'm using 3 mics simultaneously. The distortion doesn't not occur in any predictable manner. Sometimes it's present from the start, while other times it doesn't happen until I'm halfway through my podcast. It's not clipping audio, more-so clicks and interference type noise. I've read some people saying there are often issues with audio drivers and USB, and others saying that it's because the power going to the mics from the USB port is dirty.

I have made a movie on iMovie HD (using a Mac Book Pro) and have burned it onto DVD using iDVD. When I play the DVD on my TV or another iMac there is distortion during any rapid movement, e.g. a quick moving arm appears jagged and lined. There is also a slight blurriness to the general picture (the sound is faultless). Why this distortion is occurring?

I have a 24" Intel iMac, with the latest version of Snow Leopard. I bought it last July and have AppleCare. For as long as I can remember I have this problem with it:
* Every 30 seconds, almost to the second, the audio from the built in speakers distorts and gets slightly louder. This lasts about half a second then goes back to normal
* It only manifests through the internal speakers, it's fine through headphones
* Rebooting makes it go away temporarily
* I've reset PRAM and SMC to no avail
* I've tried turning Time Machine off to no avail
* I've taken it into my local Apple Service Centre, they couldn't replicate the problem, it only seems to happen in my house (every room I've tried it in is the same)
* I bought an expensive power filter/conditioner, this hasn't helped at all

I am having a problem playing some mp4 files through Quicktime. When the video is played in Quicktime (or Pro Presenter 4), portions of the video turn into distorted white blocks that move with the video. It doesn't continue throughout the whole video, but I can't discern when or why it only affects certain portions. It does it every time at those places in the video. I downloaded VLC, and the same exact file plays perfectly fine in VLC and on other computers through various programs. I have only seen this problem on this computer.
Is this a codec issue? How do I fix it? The files in question are mp4 files using h.264 video and AAC audio at 1920x1080 resolution. I can play other mp4s using h.264 and AAC without any problems.
I have only had this problem with one of the companies that we periodically hire to produce videos for us. I'm guessing that it has something to do with the way he encoded the video, but I have no idea what the problem is. It's probably not his fault if it only distorts on this one computer.
Here is what the white block distortion looks like:

iMac, Mac OS X (10.6.8), 3.2 GHz Intel Core i3, 4 GB RAM

This gets asked a million times on a daily basis I expect, so sorry about that! I've read the upgrade section which is very helpful but I was looking for some recommendations / advice on what HDD&RAM upgrades to buy. I was looking at a seagate momentus (ST9500420ASG) 500GB, 7200 but when I googled the model number, the first thing that came up was a post on the seagate forums regarding incompatibility with the Mac due to the fact this hard drive has a free fall sensor which apparently conflicts with the built in sudden motion sensor. Anyone have any experience on that? I need a drive that will run at 7200rpm so this checked all the boxes for the price but could be out now? I have read the SR 3,1 will take 4GB of ram so I was just looking at the dual 2GB corsair value pack (VS4GSDSKIT667D2).

Quick question guys, I currently have a Powerbook G4 17 inch with 1.5 Ghz, 2GB of RAM and 80HD. I love it, with the full powered RAM it flies, but, I HATE ITS SIZE, i mean its not that portable. I have at home a Mac Pro so the power im looking for i have it on that machine. I wanna try and change my Powerbook before the new ones arrive because i need PORTABILITY. Is it really a big of a difference? I mean i dont need the "power" of the powerbook because i have the macpro at home. With 2 GB of RAM, will a macbook (lets say the current ones) be really faster and more efficient than my old PB G4? I like the 17 screen but i need portability so bad! what do you guys recommend?

I recently decieded to step into the adventure that is world of warcraft, and I have experienced kernel panics once every two hours or so of playing. I wonder if my ram is sliding out of place, or i should reinstall w.o.w. If it helps any, when I restart my macbook, it tells me a bunch of seemingly random coding as well as mentioning world of warcraft.

I have a network shared folder added to "Places" in Finder. I have also dragged a shortcut into the dock. The problem is that when I click the shortcut in the dock, the "stacks" doesn't pop up. Instead, it only pops up when I click a second time. After that, it works fine. It stops working after I restart the machine, so I have to click again for it to work.
So basically, it looks like when I click it the first time, it "makes a network" connection to my windows PC where the network folder is located. This looks like probable because the fact that under "Shared" in finder, the PC isn't listed UNTIL I click the mounted network folder in the "Places" in Finder.

I have a 2.2Ghz Macbook Pro 15" (2007) that suddenly can't get past the startup screen and ends up with a kernel panic and the You need to restart message. Happens 100% of the time now. I had Leopard on it when it started kernel panicking. I managed to boot from an external drive and installed Snow Leopard, but it started okay once or twice, then started having the kernel panics at startup again. Tried SMC reset, but no go.
I then tried going back to Tiger, thinking it might be a problem with the RAM. Tiger actually installed okay, and after it worked okay for a bit (2-3 times, maybe half an hour), I tried to install Leopard again. And got only kernel panics. And I can't install Tiger now either.
It occasionally starts up from an external disk that I use for installs (has Leopard and Snow Leopard on it), but that's not 100%. And I can't even get thru an install now. I started up with it in Firewire Disk mode, wiped the drive and cloned a system from my iMac, but even though it seemed to go okay, when I shut it all down and tried to restart the Macbook Pro, I got another kernel panic. Any ideas? I've switched 3-4 different RAM modules, and I don't think they're ALL bad. But no go. I've changed hard drives too.
Seems weird. I mean, it doesn't seem broken, as it starts up, goes thru the startup screen, seems to pause a bit and, instead of going to login, stops with a kernel panic. I assume it's HARDWARE, not software. But hardware problems are usually the RAM, sometimes the hard disk; and if the MBPro doesn't start up at all, then the logic board is probably fried. So what else can cause these kernel panics? A bad keyboard/trackpad (top case)? Bad PRAM battery?

I've been trying to keep track of how my 2ghz unibody Macbook uses its RAM, and I've been curious as to why after some time it reports that I have as little as 30 MB of free RAM left. It obviously reports that the rest is in use, but the numbers just don't add up to 1.9GB of used up RAM. What is my computer doing that is not being reported, and how do I get it to stop? It has made my machine noticeably slower. I've posted a screen shot to illustrate. It may help to know that I had been a Windows user for years. In Windows we can launch msconfig.exe to manage which programs get to run in the background and at start up, and from there we could decide to shut down programs that check, for example, for RealPlayer updates and other completely unnecessary executables. Can someone give me a run down of what I can safely eliminate from my processes in my Macbook, and therefore keep more RAM free at all times?
