I was browsing the internet on my '08 iMac when the system suddenly froze immediately followed by the screen turning to nothing but vertical lines. I fear this may be an issue with the graphics card, but would anyone be able to offer any further insight?
View 3 RepliesMy computer (24" 3.06Ghz intel core 2 duo) won't start. When I try to turn on or restart my iMac I get vertical rows of pixelated lines across my monitor on the white startup background with the apple logo and it will either freeze up or the background turns gray and I get a message that says I should restart my computer. This has also happened when restarting using the Apple hardware test (which doesn't report any errors).

does any one have any idea of what is causing the problem, and the solution?
This just started today. My computer started to get weird vertical colored lines on the screen. At first, I thought it was just the website I was on, but more and more began to appear everywhere. I unplugged my computer and plugged it back it, turned it on, and when the white screen witht he Apple logo came up, the lines were everywhere. They weren't just making vertical lines, but also squares. Later, the weirdest thing happened. I was opening a new window on Safari, and suddenly, these pyramid-shaped objects covered the screen. They were red, with a little with of blue and a tiny bit of white on them. they pointed in all directions, and the minute I moved my mouse, they dissapeared. When I hold down on the left button on the mouse and hover it over the squares and lines, about 65% of the dots dissapear. My computer is an iMac G5 from 2004 with no iSight, the model number is A1058, the software is Leopard (10.5.8), and the processor is 1.8 GHz PowerPC G5.

I have a problem with the display of an iMac G5 20". It shows up as vertical lines of small squares.
If I change screen resolution, the display will look ok for about half a second, and then it comes back again. Anyone had seen this before? (This is does not look like the usual problem with iMac and thin vertical lines.)
I've got a 2006 17" iMac (serial # starts with QP) and it's developed several bright, vertical lines on the display. Been reading around and it appears that this is not an uncommon problem. Whether this is something that can be repaired.

They started real small I thought it was just me then an hour later it expanded, 6 hours passed, it's a least 5 inches wide.. It started on the right, around where the time is shown.
What's happening? I have an early 06 iMac.
I have a 20'' iMac with a 2.4GHz Core 2 and an HD2600XT.
There are light vertical wavy floating lines visible on the screen when running Windows XP. They are more clearly seen when you look the screen at an angle, from down below you look upwards to the screen. The floating lines can be precisely seen on grey backgrounds. These lines are not noticable much, but when you closely look with grey backgrounds, they are visible.
The problem is very strange because I've tried updating the drivers to my HD2600XT, and no luck at all.
I'm not able to determine wether the problem is hardware of software related, due to the problem not existing in Mac OS X.
I have a 2.8GHz Intel Core 2 Duo 24 inch iMac in may-june 2008. I bought it because I wanted to avoid the 20 inch display problems. Somehow I feel I ended up with the wrong side of the deal. Check the snapshot please:

What would you do in my place. Would you risk getting another one, maybe a crappier one? It is ludicrous that you take part in a russian lottery when buying a fairly expensive product like a Mac.
I just plugged headphones into the headphone port on my iMac(dual core 2.4) I went to system preferences, sound, then output and only the internal speakers show up. I rebooted the machine and still, same thing.
I tried the same headphones on the eMac sitting next to it, and it worked just fine. Still confused about the iMac
I've been having this problem for the last few weeks intermittently, and occurs whenever I bring my Macbook Pro (17 � 5,2 � 10.6.4) awake from sleep, or sometimes just when I switch it on.
It is a bit difficult to describe, so here is a picture:

I have to hard-reset the laptop to fix this each time...
Do I need to send it away for repairs or is this something that I could fix myself?
For the past few days, my screen has been going in and out of being entirely covered by 1px white lines that occasionally flicker blue or something. Like, when I'm typing (as I am now) if the window is positioned one pixel off, the blinking cursor won't appear (and on my black screensaver, it looks more like it's white/light grey because literally every other 1px line is white). Well, this morning it got weird again, but it hasn't gone back to normal!
I have a Mid-2007 Santa Rosa Macbook Pro, 2.4 Ghz Core 2 Duo- LED Screen, backlight works fine and if I turn it completely down ('off') the problem persists. I have Boot Camp installed, and the problem persists when booting into Windows as well.
I looked around and tried a few fixes to no avail (slept the screen, reset the PRAM, messed with the resolution a bit).
I took a screenshot and everything shows up normal. I had to finish a paper I was working on, and the screen was getting unbearable, so I tried plugging it into a mate's external lcd and the image came up completely fine, no vertical lines!
So, what could this be, and what could I do to fix it? Could this be the infamous problem with the Nvidia 8600GT M graphics card- so would I have to get the logic board repaired!? (UGH I hope not) Could it just be a connection issue? I did install a new hard drive, a new stick of memory, and Leopard, but that was months ago! Anything else I might be missing? and I hope this problem isn't too serious!
P.S.-on a side-note, has anybody done the upgrade to the latest firmware for the fans (SMC something)? Should I give that a try (or should I do it anyway, regardless of whether it could help)? When it was released, I heard of some bad experiences, so I stayed away.

Started with 1, now there are 27 vertical lines on the screen - this interferes with photos and is unbelievably annoying. How do I get rid of them?

Hi I'm connecting an external monitor to my macbook pro and am experiencing regular vertical lines throughout the external screen. I've tried DVI-D and VGA. I've tried changing resolutions. I have taken a screen shot of the monitor but this screen shot shows a clear image. Attached is a picture of what it looks like. Hard to spot as taken with my isight. (Ignore the cable hanging down).

I've had it sent into Apple once for the horizontal flashing lines, but these are new... it's like a gray vertically striped film covers the whole screen, and unlike the horizontal lines, shaking/hitting the screen does not help.
After installing Snow Leopard, I noticed that when I select a web page from the Safari startup grid (medium 6 web pages), the screen turns white with many vertical lines. This lasts for approximately 4-5 seconds before the web page loads. Any suggestions on how to fix this problem?

My MacBookPro 15" 5.3 worked fine until today, All the blacks (rgb 0,0,0) on the screen become red stripes.
When I boot into Linux or Windows the same problem appears, so it's probably a hardware problem.
I have no expensive adaptor to connect to an external lcd screen, so I don't know yet if the problem is in the mac screen or in the cabling or somewhere else...

I have recently noticed two vertical lines (seem to be a lighter shade of display screen color) running top to bottom on my desktop. They stay on my display screen all of the time. This lovely old guy was purchased May 2006 but has every upgrade (except Lion....running Snow Leopard) and full component of memory...serves me well but I need to know if this is a sign I am losing my hardware.

Its a G5 iMac ihave been using for abt three years now. first i got the vertical stripes about two months ago and today when i tried to switch it on, it won't. I turned it off last night after use and when i tried this afternoon, it was hot and it does not turn on?
I have a G5 about 2 years old. Recently a pale pink vertical line appeared down the screen, another about 2 weeks later and today a third line appeared. They do not affect the screen's visibility, but I wander if anyone else has found a resolution to this minor problem (without having to go out and purchase a replacement.

I replaced my cracked LCD screen on my 17" macbook pro, and upon firing up you hear the chime, and the apple logo comes up just fine. Then after that it goes to horizontal lines, and no image on it. If I plug in an external, it shows up just fine on it, and if I put in the original cracked screen, I can see my desktop and everything as well.
View 16 Replies View RelatedMy 2008 Penryn White Macbook siplays vertical lines and or vertical grey/black bars on 60% of the display. This happens from when it is powered on until and including when you arrive at desktop. The space the lines occupy does not increase or shrink, they have covered the area from the moment the problem arose.
it is not the common line issue that a Tiger update solved since this Macbook came with Leopard pre-installed. The lines are still there with the hard drive removed and they are still there when I booted a live Ubuntu CD, so I have ruled out software being the cause. Also I have ruled out inverter because I would not be getting any backlighting.
So....
To me that leaves:
-The LCD display panel itself (although there is no physical damage and it has never been dropped)
-The display data cable that connects LCD to the logic board
-GPU
