Gray vertical lines on startup

Ever since I switched to Lion and FileVault to encrypt my disk, when my Macbook Pro (Early 2008) Restarts it has Strange Gray gradients extending from the bottom and fading out near the top of the screen. It only happens after I log in, the initial log in screen is fine and they seem to go away eventually. Is this expected behavior?

Is this expected behavior?

Gray vertical line on crop

Hello! I imported a .mov clip that was shot on green screen. I cropped the clip on the left to remove some of the "non-green" elements. When I do a preview I see a light gray vertical line where I did the crop. Not sure what's going on there. Any ideas?
You can see it here:

I'm using Motion 5.0.4
Thanks!

I have seen this efect before and I don't recall there being a solution given. You might try using a B-Spline or Bezier mask to mask out the elements on the left instead of cropping. I have had good luck with that.

Am I seeing thin gray vertical lines on my 8X10 print because I am using the trial version?

Am I seeing thin gray vertical lines on my 8X10 print because I am using the trial version?

No. First check your ink levels and try printing something from another program to be sure you don't need to run a cleaning routine for your printer. Also, if you have an older printer occasionally you'll see those lines if your resolution in ppi isn't a whole number (in other words 347 ppi works, but 346.983 makes lines). That's not so common nowadays, though, so unless your printer is quite old it's unlikely to be the cause.

Iphone 5 gray vertical lines

Any ideas:
I have my mother's iPhone 5. Screen broke so we had it repaired at the Apple Store. So now the same device has a "newer" display assembly. However, all of a sudden, the screen went blank. Apple Store acknowledged the issue and replaced the device. However, two months ago, on the phone there are gray vertical lines and the touch is not responsive. The phone works otherwise except for the LCD and touch screen. The phone is out of warranty so I bought a display assembly, replaced it myself. Since it was an "LCD" issue, replacing it would solve the problem. However, even with the replaced display, the same problem persists. I still have gray vertical lines and touch screen is unresponsive.
All connectors are seated properly. Powercycled the battery. Any ideas?

don't be afraid to upgrade, it's surely an hardware problem. If that thing happens again, go to apple store, they will repair it or gave you an other one, the warranty is one year .

Green vertical line at startup

Has anyone experienced this before?
2009 iMac, happened at startup and will not bootup.

That often means there is a problem with the GPU of your iMac (it happened something similar to me: startup screen with vertical lines and then a white screen). Take your Mac to an Apple Store or reseller to get your iMac repaired.

Gray vertical lines on MacBook unibody screen!!!!?

I received my MacBook for Christmas/graduation I have had it less than 3 years. I absolutely loved this computer until now. One day I was surfing the web and all of a sudden my screen went gray with vertical lines and I can no longer use it. I'm very dissapointed considering that I have babied this computer since the day I got it and never dropped it or anything! I went to apple and they said most likely it will be batten $600 and $800 to fix it. I am a college student and I can not afford that. Apple employees have also said they have seen this before and they can't explain to me the problem Nor do they know how to fix it right the first time. I don't know what I should do I am truly upset that there is no reason this should be happening and as much as I love (loved) my Mac I'm probably just going to have to get a cheep computer that will last longer... Unless anyone knows how this can be fixed cheep I will turn my back on Mac

GPU is failing or bad cable or connection.

Blue and Black Vertical Lines on Startup then freeze 10.7.3

I have a 2007 MacBookPro. shortly after installing Lion 10.7.3 and VectorWorks 2011 I started getting vertical blue and black lines across my screen on startup. They remain with in the apple while the computer boots and the everything freezes. I tried all of the usual fixes, recovery, safe boot, reset PRAM, battery, etc. Nothing helps. When I tried to boot of a system disc I get a message sating that I need to restart my computer. Upon restart same problem occurs. 2 months ago I took the whole thing apart and cleaned out the guts. Reconnecting all cables back together, I came across, what I think is the camera cable. Since my camera has been erratic, i decided to test the problem with it connected and then disconnected. Connected same problem. Once i unplugged the camera everything went back to normal, until now. The same problem returned. I cleaned out the guts again. This time I unplugged the hard drive to try and boot off the C drive, but still get the same problem. This morning It decided to boot up. I was able to copy my essential files onto an external drive. Any one have any suggestions on repairs or what the problem may be? Hardware, Software? Should I do an erase and install if I can get it to boot off the C drive? Any suggestions would be appreciated.

Once I was able to boot off the C drive and performed a hardware test of the systems disc only to find nothing wrong??????????????? Since It booted this morning, I am working on it as we speak, everything seems normal except I had to adjust the time and date. Oh, I got a error message upon boot. I don't understand the code in it, but it seemed like the kernel was confused. I am afraid to shut it off and not be able to reboot again.
Unfortunately, no apple store where I now reside!!!!
Thanx

20" iMac screen is gray with blue and gray vertical lines after restart

Hey, I have a 20" Intel iMac that I purchased about 2 years ago. I have had no problems with it at all until yesterday afternoon. I had just woken it from sleep (no problems at all with the screen), used it for 5 minutes to check email and then left for 10 minutes only to come back to this on the screen:
http://www.flickr.com/photos/47548003@N03/4357722284/
I have tried restarting with the same result each time. The computer starts up with a gray screen that fades around the edges to the picture shown above. I am still able to use the computer with an external monitor, so obviously just the screen seems to be affected. Any ideas about what could be wrong?

Welcome to Apple Discussions.
It looks like the graphics card may be failing. If you are covered by AppleCare contact Apple immediately, if you are not I would recommend bringing it into an Apple Authorized Service Provider to be checked out.
Sorry for being the bearer of bad news.

Blue and gray/black vertical lines on start up screen.

At start up my 2008 MacBookPro brings up a blue and black/gray vertical lines covering the entire screen. It has a large image of the power button and tells me "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button". We've tried that. It restarts, makes the start up noise and gives the same prompt with the same blue and gray vertical lines in the background. Any idease on what our problem is?

Hi, my iMac Intel CoreDuo 20", display vertical lines at startup and isn't possible to log-in in the system.
If I turn off and turn on the iMac many and many times, sometimes I can resolve this problem.
Does anybody knows this problem?
Is the Ati x1600 broken or the lcd monitor??
Thanks!

Vertical lines through screen

I have 2 small gray vertical lines down my iphone6 screen and the screen and buttons in that area won't respond. Has anyone else had this problem and is there an easy fix?

Hello elaforce,
It seems your display has vertical lines and will not respond. Based on the information you have provided, it appears your iPhone needs to be serviced. The following link should help you get started with the process and has links with additional information on topics such as warranty and service pricing, battery replacement, and express replacement service.

Startup Freeze - Vertical Lines on Screen

Hi -
Running 10.4.7 on a new Macbook - since a firmware update about two weeks ago, my macbook freezes on startup - no chime... just goes to gray screen and slowly develops vertical lines. I can restart by resetting the nvram and then everything is ok until the next restart - or wake-up from sleep if I'm only on the battery.
Apple has already replaced my battery once and that seems ok now... but this start up thing worries me.
Has anybody seen this or reported something similar to Apple? seems like it would be related to the firmware update... but they aren't saying if they're hearing it from anyone else.
Thanks for your help

Hi, Altoklez. Welcome to the Discussions.
1. You wrote: "Has anybody seen this or reported something similar to Apple"If they have, they would probably have reported it on the MacBook Discussions. Have you checked the MacBook Dicussion for similar reports?
2. Run the Apple Hardware Test (AHT) that came the affected computer. See my "Apple Hardware Test" FAQ for comprehensive advice on using the AHT in troubleshooting.
3. Frankly, given that the machine has already been repaired once, I'd have Apple look at it again. If there is an Apple Retail Store in your area, I'd recommend taking it there. You may wish to call ahead to make an appointment at the Genius Bar.
Good luck!

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.

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.
