Vertical green lines while watching DVD on M40-148

When I try to watch video or DVD on my new laptop there is several vertical green dotted lines across the screen.
Why is that? And how do I get rid of them?

Hello guys
It is very strange issue. A friend of mine has also M40 and I have tested playing DVD films and everything works fine. It is very strange that you see those lines just while DVD player runs. Something like that should not happen.
In my opinion you should reinstall the unit with recovery DVD and dont make any installation. Immediately after operating system installation try to watch DVD using preinstalled DVD player. If the problem persist contact service partner and let them check the unit. The unit is pretty new and warranty is still valid.
As far as I know the recovery image is tested and something like that should not happen.
Good luck!

    Can anyone tell me why my 27" iMac displays vertical green lines when it is turned on and then will not boot up?

    Welcome to Apple Support Communities
    The display or graphic card are damaged. The only thing you can do is to take your computer to an Apple Store or reseller to get your computer repaired.
    If you use an external display with your Mac, connect it to your computer and see if these lines appear on the external display. If so, it's a graphic card problem

    This question is shown as answered, did you find a solution??? I have the same problem, but not with the original effects. Just with the ones that I uploaded from apples website.

  • Overheating while watching dvd

    hi,
    i have a problem with overheating of my macbook while watching dvd. after a little while of watching, it doesn't react on anything..i can't change the volume, i can't do anything, it doesn't matter if it is by clicking on trackpad or by apple remote, but dvd film is still playing without break.i always have to push the power button for a while and turn it off and then on when i want to do something else. i have read about the rear vent, but where it is?? I would like to check, if some little plastic is not stucked there. please tell me somebody where is it exactly.macbook is still very warm. i always try not to charge a battery while watching. but it is still the same.

    That should not happen - I can play DVDs without incident. You can open the Activity Monitor to see if a LOT of CPU is being used for some reason (or a lot of RAM). In the end you should take it in to Apple Service.
    On another note - if you watch a lot of YouTube, the Flash video is a challenge to MacBook's little video chip and it does make the fan run and it gets hot, but that is the only bottleneck.

  • Fix cost for 1 pixel vertical green line

    How much would it cost to fix a monitor with 1 pixel width vertical green line down the screen?

    Hello,
    I have a similar issue since this morning.... MacBook Air 13"  C02GM1ASDJWV
    And also 3 months after the warranty is over....Strange.....
    In general, i'm starting to be disapointed with apple products as like my iphone, i had issue juste after the one year warranty was finished. I'm wondering why?
    Please notice that i'm a user since a long time of mac products and didn't had any issue before. It was the reason i was staying a mac user. But now things seems different.
    I'll have a look if i can change my computer screen my self or for  a sheap price somewhere. But no way that i spend 500euros for that....

  • Thin vertical green lines on 30" Apple Display

    I am occasionally getting patches of short vertical green lines on my 30" display
    using Nvidia GF8800GT 512MB
    If I put system to sleep when it awakes it's ok
    is this indicative of pending failure
    this is the second graphics card in my new two month old Mac Pro, original card just stopped working.

    Hi
    Not yet resolved it is erratic when it occurs but lasts for the session and is apparent in any graphics irrespective of application. I had a feeling it was a graphics card problem but may be wrong. I will have to try a stress test when I get chance.
    Regards

  • Vertical green line on Qosmio's G20 LCD Screen

    (Sorry for my bad English)
    Hi all,
    my laptop have a vertical green line on the right side of the screen.this line is visible in BIOS screen also. so i think it is a hardware related issue.but one good thing is that it is not visible in a white background.i don't know why;
    Is there any thing i can do other than replacing the screen(i don't have any warranty on the LAPTOP :( )
    The problem occurred after installing windows 7 beta edition,it changed my resolution to 1400 * 900 and i think which may cause an overheat on graphics card which may lead to my problem.
    Please help me.

    > Is there any thing i can do other than replacing the screen (i don't have any warranty on the LAPTOP )
    I would not replace the screen before you would not know whats exactly wrong.
    I mean there could be also a graphic card issue and not screen issue.
    In your case I would recommend connecting the machine to the external monitor to check if the same vertical line would appears on a second monitor.
    If the same lines are visible on both screens then its definitely not a screen issue but GPU issue and in such case the mobo must be replaced :(

  • 30" ACD  Vertical green lines.

    My compueter was in Screen saver mode and when woke it up there are vertical green lines in bunches of 5-8 intermittently across the screen. Is this a monitor issue or a graphics card? Had monitor for 3 months and no such issues before.
    G5   Mac OS X (10.4.7)   30" ACD

    Could be the display or the video card. Sounds like something is temperature sensitive.
    Blow out all the dust in your mac pro.
    Reseat the video card.
    See if these help.
    You would need another display to check the card and another computer to check the display.
    Also see if any of the threads in the More Like This section on the right side of this page have any ideas.

    imac 21inch 2010 on boot vertical green lines then white screen ,will not load can anyone help please

    Howdy carliosa,
    If your iMac is not starting up normally you may need to do some checking to make sure things are working correctly. I would suggest starting with the steps in this article -
    Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support
    Thanks for using Apple Support Communities.

  • Vertical wave lines while recording

    I've never had this problem before but in a new project I'm working on whenever I start recording, vertical lines appear in whatever track I'm recording on. They disappear when I stop recording. Now I'm getting static on random tracks. I checked all connections and opened an old project and didn't have the same problem. Any help would be greatly appreciated.

  • Vertical Green Lines

    I am having a VERY annoying problem in final cut. All of my footage now has green vertical lines running through it.
    Here is a picture of what it looks like:
    http://www.flickr.com/photos/[email protected]/4731527252/
    When I open the source footage from the browser, everything looks fine, but the same clips in the timeline do not. If I do "replace edits" on all of the cuts, it fixes the problem temporarily, but soon it comes back. Exporting the video sometimes seems to help (i exported it once as prores from FCP and it was fine, I exported it once as H.264 through compressor and it had the lines).
    I have also tried using a preferences manager to backup, delete, and restore my preferences but that didn't help.
    Making a new sequence or even project and copying the cut over didnt help.
    For the record this only seems to have affected this one project so far that I have noticed. I have opened the project on another mac and it worked fine.
    Any ideas?? I am stumped. It sounds like it is my final cut, computer, or maybe video card? Im not sure and could use any advice you have.
    Thank you

    Called apple care today and they suggested I try the exported files on another comp to see if they work. They also suggested I make a new user account and try to run FCP there.
    I don't have immediate access to another computer, BUT I did try the new account. Opening the exported H.264 file that I made in my main account still showed the green lines, but when I started FCP the problem didn't seem to be there (although since the problem was sometimes spotty that doesn't necessarily mean its fixed but I played with it for a while and seemed to be working). Also, I was able to export a copy of the film that did NOT have the green lines on it (when viewed from either account). So this leads me to believe it is a software based issue of some kind, although I can't really think of what to do.
    Any suggestions?

  • Problems while watching Dvds

    Hi
    I have bought a 32 Hl833 10 days ago
    -- everything is alright while watching the regular Tv channels
    -- the problems is when I am watching Dvd movies on my Dvd device
    -- Dvd device is connected with TV with Scart
    (P.S., I am from the eastern Europe)
    -- now, the trick is that for unknown reason, while I am watching Dvd device, my Tv is constantly "losing the contact" with device, or like he is trying to identify the device over and over again
    -- in reality it means that I am watching a movie, and the Tv is "refreshing" the connection with Dvd device like every 30-120 seconds
    -- to describe it better, it feels like:
    = you are on the channel for Dvd (output channel 1 or however it is called) and watching a movie, and every 30-60 seconds you get the black screen (the same like when you are switching between channels with your remote controller)
    -- so, you know the feeling when you are on Channel 2 and then you click Channel 3 on your remote, and then from the channel 2 you will see the black screen for a few moments and after that you will be redirected to a channel 3
    -- and on the top of the screen, you will see the Info, like: Channel 3 in the left top corner and the clock in the right top corner
    -- so, while I am on the Dvd channel, it basically feels like the TV is constantly switching channels (without me doing that)
    -- but that switching feels like constantly refreshing the same channel over and over again
    -- and while watching a movie, it is extremely dumb and annoying
    -- you are watching it, and every 30 seconds, you lose the picture for 1-2 seconds, you see the black screen, and then you are on your channel again, and you constantly see the info (number of channel, clock and date on top of the screen)
    ** It never happens while watching the regular Tv channels
    -- so, there is a some problem in connection/compatibility of Dvd device and my Tv, I guess
    -- also, sometimes it happens that this problem doesn't happen for 90-120 Minutes at all (or once in the whole movie), and on the other days (this evening again), you get this problem every 30 seconds and it is basically impossible to watch the Dvd
    -- I tried to turn off both my Tv, Dvd device, checked all (Scart) connections 20 times
    -- problems is still here
    ** also, if it happens, it seems that my remote controllers for a Dvd device and a Tv controller have very similar codes
    -- for example, I press the Up button on Dvd remote controller, and my Tv suddenly switches to a channel 7 on my Tv :/
    -- so, Up button on Dvd device has the same meaning/code as the button for channel 7 on my Tv :/
    Anyway, sorry for the long post
    I hope that someone will have some good idea
    Thanks in advance

    Oh, sorry, I didn't know that this is only for Us models
    Anyway, I asked some friends of mine for the advice, and they advised my to try with a new scart cable
    I have bought a brand new cable, and it seems that it works good now
    (Even though on the old TV, even the old cable was "good", but nevermind)
    Anyway, I think I have solved the problem and it seems that the problem was connected with the cable and not the Tv
    Thanks anyway

  • RE: External speakers don't work while watching DVD on MacBook

    Hello, I have a late 2006 white 13-inch MacBook. I have been trying to use an Altec Lansing external speaker while watching a DVD movie on my Mac, in order to increase and improve the sound, but when I plug the speaker cable into the headphones jack on my Mac, no sound comes out of the speaker. The speaker works fine when I plug it into the same jack to listen to music in my iTunes library, so I know the problem isn't with the speaker per se.
    Can anyone tell me how to fix this problem? I have tried to play around with the Sound on System Preferences and with the Audio MIDI setup but I'm not sure which setting is at fault. Thanks very much.

    Hi, thanks for your response. When I got into Preferences>Disk Setup, under Audio Output, "System Sound Output" is selected (there are no other options listed). Also, "Disable Dolby dynamic range compression" is checked.

  • Screen Sleeps while watching DVD or Stream

    Hello
    I have a problem with my PowerBook. I hate the energy saver function. When I use normal programs everything is o.k. and when their is no input it sleeps after a couple of minuten.
    The problem is that while I watching an DVD or an Interstream my energy Saving Options put my screen to black because their is no input or mouse moving.
    Is their a way to prevent the screen to go to black without switching off the engergy saving options while watching a DVD or Stream??

    Disable all sleep functions. IMHO, they're overrated.

  • How to put MacBook Pro display to sleep while watching DVD on 2nd Display

    Not sure if this is answered elsewhere, but I have a MacBook Pro with a second larger display attached thru DVI. As I watch DVDs on the external display, I would like to darken out the MacBook Pro screen so it is not distracting while watching the movie. I seemingly can't put only the MacBook display to sleep - both displays goto sleep. I can't close the MacBook either. Any suggestions. Thanks.

    Hold the '"Darker" key down until the screen is ghostly.
