OS X :: IMac 24" 2006 - Odd Pixelated Line On Screen?
Jan 14, 2010
I have a late 2006 24" IMac which has a myriad of issues. The most concerning to me at this point is the occasional appearance of a 1-2 pixel wide horizontal line which runs from 2" across to sometimes as much as 12" across the screen. It happens most often on the desktop and in firefox. It disappears as mysteriously as it appears.
Could the graphics card be going bad? Any ideas on what might be happening and how I might be able to solve this.

This is the image I get on my iMac 2.4 GHz Intel Core Duo OSX10.5.4. I have repaired permisions and removed all login items. Once I move the cursor or open up a window the screen clears behind the cursor or window etc... It freezes up at least once or twice a day...
I started up again and attached another screen, the image was normal on both screens. But alone the iMac still starts up with the pixelated screen.

I own an early 2008 iMac running Snow Leopard. A few months ago, it started getting a little buggy and running slow, you know, things you would expect from a computer that's now 2 years old. But then it started freezing and giving me "kernel panics". Of course, the first thing I did was install VirusBarrier and remove any and all viruses it could find, and I repaired the disk and disk permissions and ran all the diagnostic tests from the install DVD. Then I left it unplugged for a day, upgraded the memory from 2 GB to 4 GB and did everything a second time. After all that, everything seemed to work just fine.
Now it seems to be starting all over again! This time the virus scan only picked up a few Windows viruses on an old external hard drive and repairing the disk, disk permissions, and running diagnostics turned up nothing. I've done everything I know to do, short of taking the thing back to Apple! Right now, the main issue is this bug at startup that's really just freaking me out. Linked is a video of what happens. The apps that run at startup are BumpTop, HughesNet Status Meter (as of last month), and Brother Printer Utility. [URL]

I have an iMac G4 running 10.4.11. (not intel). When I turned it on today, it was all pixilated, little white squares in between the colored ones. I can hardly make out what is on the screen so I can?t really choose anything using the mouse. Everything else seems normal except for the the screen.

Got the iMac 27" Late 2009 (bought it when it came out). Its always had the 'pixelated' issue (see attachment) just before the login screen appears but I've never bothered too much as its not been a problem, until recently where I am getting a lot of 'Kernel Panics' (screen wipes down and locks done entirely, have to restart to get the system up and running again). I am starting to think that the screen issue is finally starting to shows its true colours. Yes, I've done the PRAM resets, disk repairs, up-to-date with all the software etc. No joy.

Let me start by saying I have swapped the ram in the computer and the problem persists. I've also tried resetting the PRAM. I have unplugged all devices except the keyboard and mouse. I have reformatted and installed OS X Leopard, Tiger and Snow Leopard. I have even encountered this issue while the computer was running from the install disk. I'm pretty sure software, ram and third party devices can be eliminated from the possible causes. The computer continues to run after the screen goes black. I am connected to it right now using screen sharing, so I know the computer is still working. Putting the computer to sleep and then waking it up temporarily brings the screen back until its next random blackout. I have opened the computer to replace a dead HD, so I suppose it is possible that I knocked something in the process, but I did that back in December and the problem is a relatively recent development. I would really prefer to fix this myself, if I could only figure out what the problem is.

My screen freezes from time to time and CPU overheats.I have increased the fan speed with SMC download but still happens 2-3 times a day when downloading or watching video, also when using SKYPE worse when using both? BBC iPlayer does not make it freeze?

I have an early 2008 Imac with an Nividia 8800 GS graphics card. It apparently failed two weeks ago, and I just got the machine back after the Apple Store replacing the card.The only graphical glitches I had on the Imac, was the faint line that would run across the screen that you could see on a white background if I left a program's window opened to long; and when using Safari, while encoding a dvd, trying to open up a new tab I would get images of whatever I was encoding in the new safari tab for half a second. Then it would correct itself and bring a blank safari page.

So I've had this computer for a while and about a year or two ago, it started giving me problems. I would hear a loud short come from the screen and then I would see a quick line appear. It started getting worse as the month went on til the whole thing shorted out on me. Now all it does is turn on and shut right off with a loud and pretty frightful shorting sound and won't try to kick back on til an hour or two later (manually anyways). I did some research online and found out that my flyback transformer on my analog board shorted out due to heat constrictions inside the machine. And when that part shortes out, it take sthe video board along with it, since those two board are conjoined together, and in turn takes the whole system out. The wierd part is when I unplug the video cord and turn it on, their are no problems, only that My screen is still off, so it's like flying a plane with no instruments. I heard there is a way to replace the inside parts of the iMac and place a LCD screen in there but I'm not sure how that works out and if it will work anyways. Plus I just read that removing the CRT can be very dangerous. Grrr. I Need some advice. I'm a college student and don't have much $$$. If I did, I would have gotten a new MacBook. I wanna bring this mac back to life cause i miss it. Is there anyway I can do that? What would I need to do?

i noticed a faint vertical line of pixels on the far left of my screen. they weren't black or colored, just faint/dim. i tried switching my desktop background, and the line was still there. i restarted my computer, and the line was still there. i shut down the computer, thinking that i would find the line there in the morning and have to take it to the apple store.
when i turned the computer on the next morning, there was no line. however, later that evening i noticed a reappearance of the line. i restarted the computer and left for a while. when i came back later, i woke the computer from sleep mode, and the line was gone.
there was no line on the computer this morning, although after a couple hours of use, i noticed that two lines had developed on the edge of where i had application windows open -- in this case, both yahoo messenger for mac. curiously, this didn't happen with other windows (finder, safari, etc).

I've had this iMac about a year now, and i have had this problem for a while but thought i'de leave it for abit and see if it heals its self. As sometimes the line is more visible than other times and sometimes it's not even there!
I have 2 pictures which i snapped with my iPhone, so i will link you too them.
The line is not majorly visible, but it is just annoying considering i payed �1000 for this iMac.
Picture1: Line overlapping my iTunes.

Picture2: Line on boot up.

I have a G4 Powerbook 1.67 that I don't take anywhere. It just sits on an iCurve as a home computer. Never been dropped, damaged, looks as good as new.
That said, the screen sometimes gives me these red moving pixels which distorts the screen image a bit (pic attached). And lately the screen has been going out at times with lines across the screen, then intermittent blackouts.

Sometime this morning the screen on my mac became very distorted (almost pixelated.) I restarted while holding the shift key and it was resolved for about five minutes, then started up again. A friend suggested it could be a blown video card? I've attached a photo.

I have a macbook Pro 13", bought in 2010. Recently my screen has been going pixelated at random times, it normally goes away fairly quick but is happening more and more. I'm wondering if it is the Video Card which needs to be replaced?

I have only recently started noticing this, it is mostly visible on the white screen at boot up but just faintly noticed it now against my background.
It is a fading black line going down the left hand side of the screen, it starts at the top kind of fades in the middle then comes out again.
I honestly have no idea what this is, i will try catch a picture on my phone soon and post it up.
Cheers.
UPDATE: Sometimes the line is clear, sometimes it is faint and even sometimes it isn't even there!

I have been having problems with my Macbook pro(5 months old) screen lately. The screen goes all pixelated and messed up, please see pictures. I don't know what is wrong and surely this can't be lag as my laptop is a pretty good model and from the most recent update.It does this randomly ever now and again but it is very concerning to me. Should i consider asking for a new mac/refund.....

I own a Mac Pro (2x2.8ghz Quad Core Xeon, 6gb DDR2 Ram, Nvidia 8800GT, running in 64-bit mode), and a 30" cinema display. I am running OS 10.6.5 at the moment as well.
What happens (and its been happening all day, rarely happened in the past), is that my entire screen freezes up for no real reason, and becomes completely pixelated and nothing but my cursor moves.
The pixelation even makes it through the force shut down and into the grey apple startup screen, the logo is pixelated there as well.
For some reason, I can't seem to reset the PRAM (no second startup chime?), and I can't seem to enter safe-mode either (shift at startup?)
Right now, the problem isn't happening, but at this rate I expect it to start pixelating very, very soon.
Does anyone have any tips?
I have AppleCare, but I need to fix this asap. I'm a photographer and a very big project depends on it (needs to be submitted by tomorrow morning).

I've had two crashes (really weird ones) since I got my mac pro 3 weeks ago. Is that too many to have and should I be worried about this?
Description: The screen distorts - I see a version of the app I had open but it's all distorted and pixelated. There are medium to small squares everywhere that imbue things w/ different colors. I can move a version of the pointer around (almost like a pointer attached to a box) but I can't click on anything. Nothing responds.

I was using my computer and it was just fine. I closed it carefully (as always) and left for a few minutes. When I came back and opened it up, the screen was completely pixelated. I turned it on and off and read several forums and tried cleaning the drives and nothing is working at all. As I've been working on it parts of the pixelation of bright colors have begun flashing a little bit. Not a lot but a little. Black doesn't seem affected by the pixelation but you can see lines in the white areas. Also when images are fading in and out, they don't become pixelated until they are at their brightest. When they are fading in and out they appear fine.The graphics card in my computer is a Nividia GeForce GT 330M. SO I'm guessing from this that the graphics card is damaged or whatever. I can't afford to have apple repair it for $400 and the nearest apple store to me is two hours away.
