Start up has pink vertical lines then monitor goes blank on iMac

I was working on my computer when all of a sudden the screen went grey with 5 vertical pink lines appeared. I have switched the monitor off, but now it starts up with the pink lines then goes to a blank screen, what is the problem?

Sounds like a hardware problem ..
You can run the Apple Hardware Test
Or take your Mac to an Apple Store or Apple certitied repair provider listed here.

Why has my monitor suddenly begun to have a moiré pattern all over – it is even showing up on my icons on the dock? It appears to be very thin bright green vertical lines. I have a 2008 iMac which is running 10.6.8. What does this mean?

Also experiencing some funky issues with my wireless keyboard. With new batteries, it will just stop functioning. Certain keys intermittently won't work. Also the fans go on as soon as I turn the computer on - some times they stay on and sometimes they don't. Ever since upgrading the operating system - I've been having many issues with this iMac. Not happy. Any answers out there?

Thanks for your reply LexSchellings, There is no disc in the drive and I went through the suggestions you put forward on the phone with Apple support without any luck. I can put a disc in but it pops straight back out again without registering on finder.
The idea of using an external drive was to enable me to avoid the cost and loss of productivity whilst machine in repair... if I have to take it in to get the old drive removed than I might as well have a new internal drive put in, although I do worry about the reliability of these apple drives given my experience with this one coupled with my limited online research ... on line forums seem to be full of people with the same problem (although perhaps searching such forums is bound to make it seem a common problem as users with perfectly working machines are less likely to post (?)) Your reply suggests that no external drive will work whilst the existing drive is in place.
As a postscript: I do realise that this is a user forum ...my secondary question was asking if anyone knows how to put forward a case/complaint to Apple... I can't find a link on the support page that would enable me to do so and I was wondering if anyone on this user forum had any ideas/experience..

What does it mean when there pink vertical lines on the start up screen?

What does it mean when there are pink vertical lines on the start up screen on an IMac ?

It means you have a hardware problem. That could be the screen itself or the graphics system, GPU.

Can someone help me with my 27" iMac's Gray screen with 5 Pink Vertical Line Problem?

Hi there,
I'm new to the forums, but I have a serious problem with my nearly 4 year old iMac 27" model.
I was using my iMac one evening and then suddenly everything displayed on the screen gets immediately pushed to the left of the computer screen. Then after a minute, my screen turns a solid gray, displaying no dock, no header bar, no options, and the keyboard and mouse suddenly disconnect.
When I turned back on my computer, it seemed to boot up perfectly normal. The normal gray start-up screen displays:
Then it displays the Apple logo and begins to spin the loading circle icon below it. But this time it adds 5 vertical pink lines down the screen from left to right. They stay in place the entire time:
And then when the login screen finishes loading, instead of bringing up my Account and my Password text box, it displays just a solid gray screen with the same 5 pink vertical lines on it, as shown below:
I've let it set for a half hour and nothing changes. During this time the keyboard and mouse seem to be disconnected, nothing seems to work with the screen or the computer itself. I hold the on/off button on the rear, turning it off and then on again. The same process happens with the boot up, the Apple logo appears, then the spinning loading icon below it, and then the vertical bars appear and the Apple logo and spinning icon disappear.
Is this a problem with the screen that an external monitor hooked up to it might fix, or is it a graphics card problem? I didn't buy the extended warranty package for the computer and it's roughly 3 1/2 years old.
Any idea what might cause this and how it could be fixed in the cheapest way possible?

I have the same problem since yesterday evening.
My google research found this:
iMac (27-inch): AMD Radeon 6970M Video Card Replacement Program - Apple Support
Maybe this is our problem. My iMac fits into this category.

Pink vertical lines on rMBP - faulty connector??

I have pink vertical lines appearing on my rMPB (mid 2012) screen. I've had the screen replaced twice already for LCD burn in and then the second screen had dead pixels and chips in the glass. But now, a couple of months after the last replacement, I've started to get these lines appearing normally after the computer has been asleep for a while. Once it warms up it seems to become more stable, but as touching the actual screen (as in slightly opening or closing it) seems to alleviate the issue - I think it could be a problem with a cable connection or something. Thoughts??

Run Apple Hardware Test in EXTENDED MODE at least 3 times back to back. If you ran the basic test that is useless. I doubt a 5 year old machine is covered by any type of warranty however you can always check to see if there is an active recall. If there is and it's still active then take it to your local Apple Store or AASP for repair. If it's not covered as I suspect then you will have to have to pay for the repairs.

Pink vertical lines appearing on screen

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.

Hi Ocean swimmer-
Greetings and welcome to the Apple boards.
Makes sure to check the cable connections at both ends.
Which monitor do you have? If you take a screen shot do the lines still show up in the same place?

My cursor has long vertical line at times

My cursor has long vertical lines at times. When I hover over a link, the cursor doesnt' change to a hand

I don't know if this applies to LCDs, but the iMac G3 and eMac had "geometry settings" in the display preferences. If you messed up the settings, things like lines on the bottom and skewed images could happen.
I wonder if the factory geometry settings are off on your iMac? There is no way to set these with System Prefs.
I found someone asking about it here: https://discussions.apple.com/thread/3019584?start=0&tstart=0

Pink vertical line

Since last night a pink vertical line is appearing on mylaptop's screen at one third distance from right side. The laptop is still in warranty period till coming 2 months.
The line appears as soon as the pc is turned on. Though there have been 2-3 occassions when the line has not appeared on turning on the pc but since the morning the line just doesn't disappear on restarting the laptop.
I thought of attaching a screenshot but the line doesn't appear on it. Please let me know what i should do to remove this line.
Need help!

HT201406 i have a frozen ipod touch the screen has multicolored vertical lines and is non responsive any ideas?

i have an i pod touch which appears to be frozen it has multicoloured vertical lines on the screen and is non responsive has anyone had the same probs

If that does not work:
Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Another Victim of the Pink Vertical Line

This is my first macbook pro and it turned out to be a flop show. I just bought my 13" macbook pro retina display 5 hours back and I have been seeing this pink vertical line for the past few hours. I restarted, shut down the computer a couple of times but doesn't seem to help. I do not see an option other than returning this thing

Return the machine and exchange it for another. You have 14 days from date of purchase to exchange the machine or get a complete refund.
Good luck,

The screen on my G4 has a vertical line that doesn't go away

My G4 Macbook has a Vertical Line on the lower screen that is about 3 inches high. It doesn't go away. What to do??

There is no such thing as a G4 Macbook. Macbooks have only had Intel processors.
However, wether you have a G4 notebook or an Intel notebook, I would want to run the Apple hardware test to check the video circuitry. Find the original OS X disks that shipped with the system, and find the one that, in small print, says 'AHT Version x.x' on the label. Insert and reboot holding the alt/option key down. Choose the Apple hardware test, and when prompted choose the extended test. If you have either of the TechTool programs they can do similar testing. Does that point out any video issues?
