Yellow Vertical Lines on Desktop

I have a 10.4.11 OS X version. I recently got 2 yellow vertical lines on my desktop display and need to know how to get rid of them. I reset PRAM and that did not work. Any advice is appreciated.

What model Mac exactly (I don't even know if it is a laptop or desktop)? Have you tried using a different monitor to see if it is the monitor?

Start up white screen yellow vertical lines

hi
when i start up my iMac it loads with a white screen with yellow vertical lines and apple logo with download bar loading then goes to white screen.

Sounds like a hardware failure. Run Apple's Hardware Test 2-3 times back to back in extended mode. If any errors appear that confirms the hunch, the ONLY thing to do is take it in for repair.

Yellow vertical line on 2009 mbp screen

I was wondering if anyone else has had this problem I have a 13" mbp 2.53 intel core 2 duo late 2009 model and the screen has recently developed a small yellow vertical line about 4 in from the right side of the monitor its obviously a screen issue because when its plugged in to the tv the line doesn't follow i have had this thing for less that two years and did not buy the apple care i have owned many apples and i'm kinda disappointed about all this especially because of how much this thing cost.

If you are in the U.S. and they won't cover it under AppleCare, these shops are often less expensive.

Your only argument might be if there is no physical damage to the machine, and you can tell them you have never dropped, nor let anything heavy lean against the machine, nor bumped the machine, nor over-extended its hinge, nor spilled anything into it. Then it might be arguably a manufacturer defect that AppleCare could cover if you still have AppleCare. If you didn't get AppleCare, let this be a caution note, that you have up to a year to purchase AppleCare to extend coverage for a full 3 years from date of computer's purchase.

Macbook 6.1 (2010) blue/yellow vertical lines and a black ink-link blob.

I have a macbook 6.1 (2010) which I noticed a few small vertical blue lines on the screen-I turned it off but today the lines had gotten much bigger and now there's a black blob on the top. My macbook is out of warrenty and there's no Apple Store where I live to bring it in and have it looked at. I've read about people having their screen replaced for free by Apple who have had similar problems. I've never dropped it and always keep it in a heavy padded case but last year I got a new hard drive installed and don't know if this will affect my chances of Apple helping me.
Has anyone had this problem?
I'd really appreciate any advice on the topic!
Thanks.

Hi...
Perhaps not so much a problem with the display but possibly the grahpics card.

Yellow Verticla Lines on my 17" MacPro

I am getting Yellow Vertical lines running down my screen on my MacBook Pro. Does this mean my screen is going bad or is there a way to repair this. It started about a month ago and now I have 3 lines - with 2 of them coming up in the last week. Any thoughts? Video card or connections between screen and video card?

Hi Anton
Yes, this is likely due to faults in the LCD or cable connection. If it's still under warranty, you should contact Apple. Unfortunately, there's no easy fix that you can perform yourself on this one.
By the way, your signature implies that you have a "G4 MacBook Pro" ... do you mean "G4 AND MacBook Pro"?

Intel iMac (Early 2008) Has vertical lines on the screen and doesn't boot.

My iMac froze up tonight, and upon restarting it there are a number of yellow vertical line segments throughout the display, and it will not boot completely into the OS. The spinning segment just stops and the computer does nothing. I inserted my Leopard disc to run a hardware test but holding D during bootup does nothing, even though I can hear the disc spin up.

Any Thoughts?

I've had this same exact issue and have had to have the graphics card replace (nvidia 8800gs).
It seems these graphics cards are defective in some way.
Unfortunately my iMac is out of warranty and I must pay 3500dkk ( 500usd ) for repair.
I'm very disappointed as to the reliability of these iMacs as I've only had it for 2 years my old iMac g4 1ghz has performed better than this and is actually what I'm using until my so called new iMac is back from repairs

Black Vertical lines and a thin yellow haze in the center of my screen

I can't seem to find the answer to this question, or one that my be a solution. I recently discovered black vertical lines and a yellow haze in the center of my ipod nano 4GB.
One discussion said I should put it to sleep for 4 hours and the lines will erase. That didn't work. What's the common cause to this and how can I fix it? And could it be because I converted it from a mac to windows itunes?

Try giving it a reset. hold down the sleep and home keys until you see the silver apple. Let it reboot and see if that fixes it.

All I see is colored vertical lines!!!

I had booted into vista and was updating it while reading about windows 7 and thinking what crap it is compared to my mac when the screen suddenly frooze and it got filled with vertical lines of random colors.
I rebooted my macbook several times but it didnt solve the problem. It did give the startup sound but vertical colored lies was all i could see.
Then I reseted my pram, reset the logic board by removing the battery and pressing the power button for 5 seconds, no use!
Upon calling Apple Care I was askied to take it to the service center. At the service center while my macbook was being checked I was busy thinking how this whole 'switching' to mac has been. I purchased my mac on July 8, 2008.
1. 10 days after purchasing my white fiber body macbook, the charger dies. I live in Mumbai, India's largest city but they have to make me wait for like a week untill the new charger arrives from Banglore.
2. In September I see a dead pixel on the LCD. Apple says untill there are atleast 5 they can't replace it!
3. In November the entier body begins to turn yellow. The bottom fiber body develops cracks. The place on the keyboard panel where the magnets connect breaks because of the magnet. Apple replaces the keyboard panel but refuses to change the bottom case saying that its not covered under warranty and that 'its written so' in the warranty (which isnt!).
4. In december i notice more dead pixels. Finally Apple arranges to send me a new macbook altogether. As the 2.4ghz white fiber body one I have gets out of stock and is no more in production they send me the late 2008 aluminum macbook 2.4ghz. wow! they also renew my warranty starting from december 08.
5. Yesterday, the vertical lines appear out of nowhere.
Accept for the fact that they sent me a much better laptop as a replacement, which shows that apple cares, the whole switching thing hasnt been really hassle free. I have come to realize that what makes apple so different is OS X and the design they give to their products. Its certainly not the hardware. Considering the fact that the charger went bad, the body turned yellow, the dead pixels on the LCD and now the vertical lines on the LED, I think apple hardware is no better than that of dell or sony. Infact, my Toshiba laptop that I'm on right now is older than my macbook(s) and hasnt faced a single hardware issue yet.
I was just wondering what would I do if such things happen (and from the looks of it, they are bound to happen) after the warranty period. The apple extended warranty is a whooping Rs.13000/-. For Rs 15000/- people buy desktop computers with LCD monitors here in India!

They have said they are gonna replace the LED panel. Also, if this was to happen post warranty, they would had charge Rs1600 for diagnosis plus the cost the LED panel. I swear to God the moment something happens to this piece of crap after warranty I am gonna throw it in the store room where i keep my junk. I'm not gonna bear the cost of a single repair and fill Apple's coffers. For now, I assume my 60 grands i spent on buying this over hyped machine is a waste.
And good this happened just days before I was about to buy the 36 grands iPhone. I would be better off buying a htc touch for 15 grands which has all the same features.
Neerav
PS. the aluminium one they sent me costs as high as 96 grands! u definitely dont expect such behaviour out of it.
Also, the guys at apple service center say this happend because i updated leopard in the wrong manner! they say i should not directly click 'install' in the software update window but should rather go to the menubar and select 'download only' and then install it! the engineer in me is confused.

Coloured vertical lines across screen - logicboard?

my pbook is 26 months old. I had the screen replaced under the exchange program recently but it wouldn't seem that this is the root of my intermittent problem.
it started about 4 days ago - the screen had what looked like a pattern of yellow vertical stitching in regular intervals across the screen - the error repeats itself until the screen is quite busy with yellow stitching. yellow on top of white but sometimes magenta on top of the blue desktop. however, it doesn't always stay there. I close some windows and refresh that part of the screen and it can revert back to the normal desktop/ dock / folder appearance. I though it might be a screen connection issue but I think that's been ruled out by taking a screenshot and that showing the corruption. I've run disk utility and disk warrior and neither can find any problem. the issue is a little random when it strikes (but has happened more regularly when connected to the internet/mail) but more randomly it goes away and the actual working of the machine doesn't yet seem affected. also, actually applying gentle physical pressure or movement can make the lines disappear only to reappear later. (a bit like when your radio isn't tuned in and by touching the dial the reception gets stronger only to go back to being a sh1te reception when you take your hand off the dial!)
would there be any value in me doing a clean re-install or resetting anything if only to confirm that it's hardware rather than software - before I join the living torment of a repair waiting list?

When i open my computer I get the white screen with apple symbol and there are vertical lines all over the screen with green pixels and after a few minutes the screen gets grey and I get message to restart my computer what happens

3 years ago I bought an IMac Desktop that I am using for a lot of things but the most important for dvd montage in Imovies and Idvd.
Now today when I opened my computer I get as usual the white screen with the Apple symbol but there were all over the screen vertical lines with green pixels and after a while the screen gets grey and I get message to restart my computer using the power button or the restart button and when I do so each time the same is happening somebody can tell me what is happening and what caused this. This computer is my work and now I have no income anymore.
On the Apple support site they are asking to enter the serial number and when I do so I get message it is wrong but it is the only one I have and I buy this computer in Cairo Egypt. I am living in Hurghada in Egypt for the moment. When I call the technical support of the shop where I buy it they are telling me that it is the hard disk or ram and that I probably lost everything on it and they are asking a big amount to repair.
Can somebody advise me on this matter. Thanks in advance

You can find the serial number either in About this Mc in the Menu bar under the , or it should be on a sticker under the foot of the machine.
If you have the install discs, try booting from them, holding down the c key and then using Disk Utility to check the drive.
You can also boot into Safe mode
To start up into Safe Mode (to "Safe Boot"), do this:
   1. Be sure the computer is shut down.
   2. Press the power button.
   3. Immediately after you hear the startup tone, press and hold the Shift key.
      Tip: The Shift key should be held as soon as possible after the startup tone but not before.
   4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
Please post back with results,
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

How I fixed the colored vertical lines on my Mac Powerbook G4 17"

Hello all,
I know that many people with a Powerbook G4 17" are suffering from the colored vertical line problem on their displays. This is were a pixel wide vertical line of color (yellow, green, purple, red, and/or blue) randomly appears on the laptop's display, usually between 24-36 months after purchase. This is also known on various internet forums as the "bridget riley effect" -- named after a painter whose art looks very similar to this effect. Many, if not all, of the laptops that suffer from this defect are 17" displays and have a serial number that starts with W8. Mine starts with W85; you can check yours by looking underneath the battery. It usually starts off as just one line, then two, then a few months pass and before you know it your screen looks like this:
This is my screen two years after the first line showed up, which was two and half years after getting it in December of 2005. Not so pretty. And completely useless without an external display, kind of killing the purpose of a Laptop. As a film editor I needed my screen to see the images and more importantly I needed it to be mobile. There's not always a screen to plug into.
I tried getting Apple to fix the problem, but apparently they're just ignoring the fact that almost all the laptops that came from this certain factory in Thailand (indicated by the serial number starting with W8) have failing displays. They delete threads and forums on their website, and try to censor and ignore the problem as much as they can. Unless some huge media blitz happens, or there is some kind of legitimate lawsuit, I highly doubt they ever will do anything about it, and you can't really blame them. They are a big business and addressing this problem with cost them potentially millions in repairs and tarnish their reputation as a quality manufacturer, and Apple's biggest commodity is its reputation. It ***** that Apple allowed this kind of thing to happen, but as things stand right now, it would be a poor business decision to fix it.
So, fellow vertical line sufferers, AKA the W8 club, my advice to you is stop holding out hope that they will pay for your screen to be fixed and get it done yourself! If you do it right you can get it done for between $60-$99. Here's how I did it.
First off, know that this is a hardware problem. There is no setting in system preferences you can change that will make the lines go away. There are failing physical parts in your computer to blame and they need to be replaced.
Second, in order to keep things as cheap as possible, you are going to replace the parts. It's actually pretty easy.
Thirdly, you are going to need a whole new display. I thought maybe if I replaced the display data cable (the cable that runs from the computer under the key board to the back of the screen) it might solve the problem very cheaply, since a brand new one only costs about $9 online. I took the computer apart, replaced the cable, but the display did not change at all. So the problem is the screen, not the cable. I needed a whole new screen, however, a brand spanking new one can cost between $350-$600. So I went on eBay, typed in my computer, and looked for computers that were being sold for "parts" or "repair." These are usually much cheaper because they are not working computers, but you don't need the computer to work, you just need the display to work. If you do this, make sure you read the descriptions. If there's any mention of display problems, move on and keep looking. You don't want to replace the display only to have the lines show up all over again a few months down the line. They wont always give you the serial number, but obviously try to stay away from serial numbers that start with W8. I found a used Powerbook being sold for parts for $63. It didn't have RAM, or a Hard-drive, or screws to keep the keyboard on, but the display apparently had no issues. With shipping and handling it cost me $94 total and three days to get it. The serial number started with V7. I'm sure with a little patience and vigilance, you can find something just as cheap or even cheaper.
NOTE: Some powerbooks have High-Res display screens, so make sure you know which screen yours has so you know which to look for.
Now, how to actually replace the display. I used an awesome website called ifixit.com. They give you detailed easy-to-follow instructions with photographs. I'll let them give you the nitty gritty of how to replace the display. Here is the actual How-to guide I used:
http://www.ifixit.com/Guide/Installing-PowerBook-G4-Aluminum-17-Inch-1-1-67-GHz- Display/258/1
The only tools you really need are a small phillips head screwdriver and a T6 and T8 Torx screwdriver (they are starred on the end, as oppose to crossed like the end of a phillips head). They say you need a "spudger" but I didn't. You can get these at any hardware or auto-parts store. Return them when your done if you are really on a budget, but you might want to take more part from this new computer in the future, so your call. You'll need to print out the instructions first, or use another computer to follow them since you obviously can't use your Powerbook. Find a flat, well-lit work space, preferably near a TV so you don't get bored while working, and use the how-to guide to switch the old display with the new one. It only took me a couple of hours to finish the whole thing, and I didn't have to pay a repair man hundreds. My display works perfectly now! It's so nice to be have the mobility of a laptop again (especially since the computer i got off of eBay came with a battery that can actually hold a charge).
NOTE: There are a bunch of screws and a few small parts that will need to be taken out while replacing the display, and its important they all go back in their proper spots. So I highly recommend you take a long piece of tape, loop it, and stick it flat onto the side of your work space. As you take out each screw or small part, stick them in order to the tape. This way nothing gets lost and when you work backwards to put your computer back together you'll always know which screw or small part is next in line and which one the how-to guide is referring to.
I really hope this helps people with this problem. This seems to be the only solution. And for less than $100 bucks, I think its worth it, especially since you now have back up parts for any other part of your computer that might fail in the future. My disc drive stopped working recently so I'm replacing it with the one that came with the computer I got off eBay; a $90 part. I tried to make this as easy-to-follow, practical, and comprehensive as I could -- for as cheap as I could. GOOD LUCK!!!

I suspect not. There are long threads with hundreds of reports, most with PowerBooks whose serial numbers began with W8 (or W85). Still there is no Repair Extension Program for this issue.
At this point, your only recourse is to discuss the issue with Apple Consumer Relations at 1-800-767-2775, if you are in North America.

Thin vertical line running across my screen ...

Out of nowhere I suddenly have a thin vertical line (yellow/blue - depending on background) running across my screen. Restarting didn't help, turning on the computer and pressing command, option, p, r didn't help either.
Anyone got a clue? I would so hate to send it in for repair

it did need repair ... ;-/. But they fixed it within 24hrs.

Imac magenta screen & vertical lines / low rez screen

iMac 21.5, just 3 months old. running 10.6.3 we now see patchy magenta tinted screen and a low resolution version of the desktop. computer seems to function as normal, screenshots of course dont show the issue. screen seems to be 'half rez' vertically showing the 'scan lines' easily
any thoughts

Hi everyone!
My Imac (Intel CoreDuo, early 2006, 24") present same problems - vertical color lines, kernel panic and finally DEATH-. Just after reading this
http://discussions.info.apple.com/thread.jspa?threadID=1580232&start=435&tstart= 0
I call Apple and a very nice guy tell me, Apple extend warranty for vertical lines problem, but only in 17" machines! I can´t believe it!
I´m pretty desperate. Someone with 24" Imac could solve the problem calling Apple?
I live in Spain, the serial number of my Imac is W8642**GN
Thank you!

Small Black Vertical Lines follow my mouse pointer AND surround all ICONS

Small Black Vertical Lines follow my mouse pointer AND surround all ICONS on my desktop. I just turned on my computer and it showed like this. I already tested my monitor and it's not the monitor.
See a picture of my problem here on my me gallery:
http://gallery.me.com/egarfias/100024
Looking at websites, it's fine the display but any icons and my pointer and things that move have these lines following! Looking at VIDEO, it's the picture is full of white and black lines though you can see the video just fine.
Any ideas? Thank you!!

I am in Safe Mode now: This is the weirdest thing: A bit from column A AND B:
The display is perfect EXCEPT for two parallel lines of 17, 3 millimeter-long black lines that follow the pointer everywhere it goes.
Get this: my current display is 1024x768, but when I change it to 640x480, the pointer and everything is perfect! (of course, I can only see a fraction of my desktop)
But then again... when I zoom in and out holding down control (in 640x480) the pointer lines appear again, but less lines. They disappear when I re-reset it to 640.
Strange.
But yeah, safe mode is NEAR perfect with the except of the cursor lines. I can screen grab my cursor though to show...

Why am I getting vertical lines below each letter I type?

I keep getting vertical lines below each letter that I type when filling in things with Firefox 4. There is one line created for each letter.

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.
* https://support.mozilla.com/kb/Safe+Mode
* [[Troubleshooting extensions and themes]]
In Firefox 4 [http://kb.mozillazine.org/Safe_mode Safe mode] disables extensions and disables hardware acceleration.
* Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
If disabling hardware acceleration works then check if there is an update available for your graphics display driver.
In Firefox 4 you can use one of these to start in <u>[[Safe mode]]</u>:
* Help > Restart with Add-ons Disabled
* Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)
