Green wavey lines on screen

My iMac 1.9 Ghz PowerPC isight has suddenly started displaying wavey green lines (horizontally across the screen) these come and go and change if you move an active window about the screen. Sometimes the whole screen takes on a pale green tinge, and sometimes the entire screen 'goes' I lose all content of screen and get white-out with some pale colours.
I have zapped pram and nvram. I have tried the re-set pmu technique. My serial number starts with W854 XXXXXX
Is anyone else having these problems? and can anyone offer any suggestions. I would really like to keep this PPC mac going as I have lots of software which won't run on intel macs.
Thank you

I, too, am experiencing green lines with my iSight camera (standalone) when I use iChat or PhotoBooth. I first noticed this happening on my PPC G4.
But now I have a new Intel Mac Pro (Dual 3.0ghz Quad / 8-core) and the iSight still displays the green lines (looks like the Matrix) on the left half of the screen only...the right side is fine. I would upload a screen shot, but don't think I can on here.
So being that it's doing this on both computers, I assume my iSight is not working properly or is broken? Any help would be appreciated.

  • Green vertical lines on screen

    dvd player sony model dvp ns57p has green vertical lines on screen.  any suggestions.  get a new playler blueray?

    Please try the steps below:
    Adjust the color settings on your TV to make sure the issue is not a simple screen adjustment.
    Make sure the disc player is properly connected. The disc player should be connected directly to a TV or Audio/Video (A/V) receiver. It should not be connected to a VCR. This issue can occur if a video signal encrypted with copyright protection passes through a VCR.
    NOTE: When the disc player is connected through an A/V receiver, you should also check the connections between the A/V receiver and the TV.
    If using A/V cables, check that the red, white, and yellow plugs are securely connected to the same colored jacks on both the disc player and TV (or A/V receiver).
    If using component cables, check that the red, green, and blue plugs are securely connected to the same colored Y/P B /P R jacks on both the disc player and TV (or A/V receiver).
    If using an S-Video cable, check that it is securely connected to both the disc player and TV (or A/V receiver).
    Try playing a different disc to see if the issue only occurs with the one disc.
    If the issue is occurring with more than one disc, replace the cables connecting the disc player to the TV (or A/V receiver).
    NOTE: When the disc player is connected through an A/V receiver, you should also try changing or replacing the cable between the A/V receiver and TV.
    Try connecting the disc player to different input jacks on the TV (or A/V receiver) and change the input mode accordingly to determine if the issue is with a particular input jack.
    Try playing another video source (such as a VCR) to determine whether or not the issue only occurs with the disc player.
    If the issue occurs with other video sources, then the problem is with the TV (or A/V receiver).
    If the issue only occurs when using the disc player, then the disc player may require service.

  • Picture Included. Mid 2012 13 inch Macbook Pro green/purple lines on screen. Freezes. Sometimes 3 beeps.

    Alright I have a Mid 2012 13 inch Macbook Pro purchased in June 2012. For about the last month, I have this issue where as I am using it random colored lines will show up on the screen (lines usually green, purple, but occasionally the issue occurs while booting and lines are black on white background). As soon as the lines appear, everything freezes. Sometimes the computer automatically reboots. Other times, it will just turn off and start beeping 3 times in a row. AT first, I thought this may be a video card error because it happened a lot when I was watching videos. However, it also happens randomly when I am just using safari/chrome with no other programs runnings. The most annoying part of this issue is that it is completely random. Computer won't act up for maybe 2 days straight during all activities (videos, surfing the web, etc). Then I will have a day where the problem is consistent.
    Also, although I think this is just a correlation, all problems started after upgrading to Yosemite.
    Picture below:
    Does anyone else with a Macbook Pro (especially 2012) have this issue? These two discussions seem to be describing this very situation:
    Screen froze, purple lines, three beeps. Help!
    Macbook Pro screen glitches, 3 beeps, NOT THE RAM

    thanks alex. I'm going to the genius bar later this week for them to get a look at the issue.
    in the meantime, do you have any idea why the problem occurs when I apply a little pressure to the bottom of the computer (under the command screen). here is a video of the situation: https://www.youtube.com/watch?v=88C34bHZAd8&feature=youtu.be
    also, i found this thread describing my exact situation: Field of vertical lines all over Macbook Pro screen? (+ freezes, beeps)
    do you have any idea of a solution from reading that?

  • IMac will not boot, green vertical lines on screen

    My iMac 27" purchased in 2012 is running Mavericks OS.  I did a software update last week, and switched on the machine for first time since then, today.
    I get 4 or 5 green vertical bars down the start-up screen with the apple logo and timer running.  The screen then goes to a grey screen and just hangs.
    Tried safe boot and nvram clear but did not work.  Will try again this evening.

  • My 06' Macbook Pro crashed with vertical, green pixelated lines and now will not advance past the turn-on screen with the apple filled with green lines as well. Then, it says to hold down the power button to restart. Help?

    My 06' Macbook Pro crashed with vertical, green pixelated lines and now will not advance past the turn-on screen with the apple filled with green lines as well. Then, it says to hold down the power button to restart. I have tried several times to get it past this point but tnothing helped.
    I have an appointment at the Apple store today, but was wondering : will all of the information and files on my desktop be lost? Or is this a logic board problem?
    Any help is much MUCH appricated.

    I'm not sure, if you're out of warrenty it'll cost quite a bit for the replacement of the logic board replacement...unless you have apple care. you could ask apple to try and recover your hard drive but i'm not sure.

  • I inadvertantly dropped my iphone 3 and now have a white screen with green vertical lines to the right.  It won't sync with itunes due to an error. What can I do?

    I inadvertantly dropped my iphone 3 and now have a white screen with green vertical lines to the right of the screen.  It won't sync with itunes due to an error. What can I do?

    Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved.
    If it does not resolve the issue, the device is permanently damaged and will require replacement.

  • Why would I get a bright green vertical line down the center of my screen after playing a game?

    Why would I get a bright green vertical line down the middle of my screen after playing a game?

    Welcome to the HP Forums!

    I grasp that you are having an issue with the display but if you adjust the position of the display it disappears.
    Here is a link to Display Quality Issues that may help.
    As you stated it goes away when you reposition the display the connection cable may have become  loose or damaged from opening and closing the display.
    Here is a link to the  HP Pavilion 14 Notebook PC, HP Pavilion 14 Touchsmart Notebook PC, HP Pavilion 14 Touchsmart Ultrabo.... Chapter 4 page 36 has removal instructions that may assist you in checking for that problem.

  • My laptop screen is glitching and it becomes green with lines

    THe screen when is moved flickers and the screen turns green with lines. And the laptop will freeze unable to do anything. Then when I shut it off and restart it makes these 3 beeping noises then stops and does these noises again.
    it is a bad problem, but can anybody give me an estimate cost to repair this issue? Please and thank you!!!

    Those three beeps indicate defective or bad RAM memory. If this is the only problem it is not very expensive (you can even install the RAM yourself), but as the screen is flickering too, I would recommend you to take your Mac to an Apple Store or reseller to see if the logic board is also affected.
    The cost depends on the damaged parts. If it is only the RAM, it is not expensive, but if the logic board has to be replaced, it will be very expensive.

  • Screen Freezes + colour distortion with Green/Pink lines, runs hot!

    Hi,
    so my computer has been running very hot recently and at first i though it was the battery, however it says it's in normal condition and has a cycle count of only 110. Then today when i went to go use one of my hot corners the screen froze and turned all grainy, producing green/pink lines all over the display. I tried force quitting and nothing work. I eventually just restarted it. This occurred two more times both while trying to stream videos online within the following two hours.
    It basically looks like one of those really old computer video games when it freezes mid-action. All the images becomes distorted and the pixels are blurred, resulting in green and pink horizontal lines all over the display. During this however i am able to move my mouse, and my computer is also especially hot during all of this. While typing i have to move my palms aways every once and while because it gets too hot.
    Any thoughts would be greatly appreciated? This has very nervous as i have a paper to write this weekend and i need my computer.
    Thank-you very much:)

    Welcome to Apple Discussions!
    Check in Activity Monitor to see if you have some hung up process running amok and hogging the CPU, which would cause a lot of heat. If you find one, quit it and see if the problem goes away.
    It's possible you have the NVIDIA problem:
    http://support.apple.com/kb/TS2377
    If so, the only cure will be to replace the logic board. Fortunately, under this program, it will be done at no cost to you.
    Do you have access to an Apple Store? If so, there is a specific test they can run to diagnose this problem.
    Also, run the extended version of the Apple Hardware test to be sure you don't have a problem with the fans or thermal sensors. If your fans are not working properly, it's possible that the graphics chip is getting too hot, resulting in the video distortion you are seeing.
    In any event, this sounds like a hardware problem that you need to address with Apple as soon as possible.
    Good luck!

  • Qosmio G15: green vertical lines on the screen

    It all started one regular day when I was playing music on my iTunes.
    Suddenly my screen went black and the music stopped, but my power button was still blue. Ever since then, whenever I try to start it, it goes on the Qosmio screen and the Windows XP screen and plays the start-up sound, but it has all these green vertical lines on the screen. And then it goes black and tsays that way.
    I have been able to use Windows VGA (whatever that means) with lines all over the screen, but I am not able to start it up normally. Does anyone have any suggestions or have had the same problem??? Please help me!!!
    I have a Toshiba G15 Windows XP Media Centre, but am not able to use it normally!
    -Alexis

    Hello, This problem happens to me two weeks ago. I have a F10 and the warranty expired 3 months ago. I rarely use my laptop. Talked to a well known local store rep. He said there was a specculation on F10 as it was discontinous after a year of release. I agree that well known company like Toshiba should operate like Car companies and be honest on their products. Specially high end product like this.
    I was not informed about extended warranty when I bought it as the local store just want to sell and sell and move on. One of the regional store which represents Toshiba to repair all Laptop, said They are only allowed to fix all laptops except Qosmios models. They have to sent it to Toshiba.

  • Green line on screen during boot only

    hi, i've a problem with my macbook pro 13" late 2011! After an re-initialization on my macbook happens that only during boot i see a green vertical line on the right side of my display and it disappear after login. This green line starts from the upper side and finish to the down side. Can it be a problem deriverd from a bad os installation??
    i'm attaching a photo but i'm sorry for bad image.
    thanks for the help!

    Try a pram reset:
    Shut down your Mac.
    Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on your Mac.
    Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears. Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.
    Release the keys.

  • My G5 iMac has a screen color problem. The color is green with lines. What can I do to repar this? Sometimes the screen will freeze and I have to reboot the computer and the screen will be normal for up to 5-6 hours and then suddenly changes back to green

    Try running in Safe mode.  This leaves out some video drivers.  Which results in machine not using advanced video hardware.

  • Blue and Green horizontal lines on my screen

    I have the 2008 version of the MacBook Pro with the 15 inch screen. While using it last night I suddenly started seeing blue and green horizontal pixelated lines going across my screen. The first time it did it, I rebooted my laptop and it was fine for a while but then they came back. This morning when I turned it on, the lines were still there. I have no sort of warranty on this computer anymore. This is actually a computer I recieved from school back in 2008. Is this a sign my screen is going out?

    Hello tattooedbeauty,
    Thank you for the details of the issue you are experiencing with your MacBook Pro display.  I would be concerned as well if I were seeing blue and green horizontal lines.
    I found an article with steps to troubleshoot issues with displays.  This article is for internal and external displays, so you can skip any steps referring to an external display.  I recommend reviewing the full article, but this step specifically stands out to me:
    Reset the system
    You can reset the Mac's parameter RAM and SMC.
    You can find the full article here:
