Satellite A50 542: lines on the screen

I have a Satellite A50 542.

I turned on and all I have in front of me are a load of lines, cannot see through them.

Anyone can suggest a remedy or solution?

Thank you very much

Hello

Don't you see the same direction on the external monitor?
If Yes, then the graphics card may be affected which means you need to replace the motherboard.

If the lines are visible only on the internal screen, then the screen itself may be faulty.

Have you tried to reinstall the display driver?

  • Satellite L830 - horizontal line across the screen

    All new Satellite L830 has a horizontal line across the screen.

    What can be the cause and how can be fixed?

    If the laptop is brand new it back as soon as possible and ask for replacement.
    On this virtual path, it is not easy to say what the problem is here, but it may be related to faulty display, especially if you can see from the first moments when the laptop is turned on.

    Don't try anything. Request a new one. If you can not new, contact the nearest Toshiba service provider and ask for help. They need to exchange the defective part.

  • Satellite L750 - diagonal lines on the screen

    Last week my Satellite L750 had pale grey diagonal lines connecting the upper left corner to the lower right corner. They cover the entire screen.

    Tried to check for update nVidia drivers in Control Panel configuration, but Windows says I have the latest version.

    No idea how I can solve this because it is very annoying.

    How can you solve this problem?
    As a first step, you should check what is may be defective. I'm 100% sure that it has nothing to do with the drivers.
    What you can do is to connect the external monitor to your laptop and check if the same will be on screen. I guess not so in my opinion, your display is faulty and must be replaced.

  • Satellite C50 - B - lines on the screen

    Hi all

    My son has bought a Satellite C50-B-153 in December last year and used as a personal laptop. One morning last week, he went to use it and worsened the Toshiba start screen met with lines, lines and more white, and then it closes.

    I tried all the 'F' with the option '0' options with no luck, read about the command causing problems so I connected an external rom to boot DVD and tried to load the recovery disc. I left him and went away for a short time, when I came back, I clicked the mouse button and the screen with the opening screen of windows, with lines session more and then and then it restarted again.

    I checked the internal cables and the cables of the screen and they are all attached properly the only thing I did not just replace the CMOS battery but don't know if it would be useful or not?

    Any help would be greatly appreciated because he is lost without her, and so I don't like it with my computer laptop haha!

    Thanks in advance,
    Emma.

    If the lines are visible all the time, you should check if they are visible on the external monitor or TV. If this is not the case, the problem is probably defective.

  • Satellite M60 - vertical lines on the screen

    Can someone tell me what is the apperience on vertical lines screen (a first in the Middle, and then, months later on the sides) means?
    Thanks in advance sekreb

    I can't say for sure, but it may be due to faulty display or may have a faulty graphics card. If possible, try to connect the external monitor to your laptop and use the FN + F5 key combination to switch to external monitor desktop.
    If the image is perfect, the screen may be defective.

    When the same problem occurs on external monitor, it is proved that the problem is caused by a faulty graphics card.

  • Satellite P100-286 - vertical on the screen restart and constant lines

    I got this P100-286 with Nvidia Geforce Go 7900 GS and recently the laptop started to freeze options even with vertical lines on the screen tried recovery cd tried to re - install and after installation, that he started to do the same. I have read similar problems in the forum and this is a common problem with Toshiba? I have spend £1500 on this and it is only 3 years old. My friends have older laptops of this almost 6 years old and in good working condition.
    Y at - it a suggestion for this problem or a solution? The heat on the basis of the laptop is really hot and it's like that for centuries.

    Any help is really appreciated after spending so much like to last longer or it is a problem of reliability with the Toshiba brand.

    Hi vns.

    Hmm strange. I have ever read on these issues here in the forum with Satellite P100. Friend of me has the same model and it s still does work correctly, no problems at all.

    Do you have the same vertical lines on a screen? If so, it is certainly associated with the internal graphics card and not watch.
    By the way: you have the same problem in the BIOS or just Windows?

    With regard to the heat on the underside: I think that it s time to clean it and remove dust. You can do this using the jet of compressed air to blow the dust from the cooling fans. That's why it of not necessary to disassemble your laptop.

  • Satellite M70-339 vertical lines on the screen

    Hello...

    I have a Satellite M70-339, which will show only the vertical lines on the screen.
    I connected an external monitor and booted in safe mode.
    I uninstalled the display drivers.
    I started to monitor and reinstalled the display drivers.
    The computer will now boot up screen.

    I put the display to indicate to both monitor and screen.

    On the monitor, all right.
    On the screen, I get vertical lines color, similar to a wallpaper (wallpaper is not pretty).

    Did anyone has got any ideas what could be the problem, or how to diagnose the problem
    Any help would be appreciated.

    If everything is OK on the external monitor that is the best evidence that this problem is related to the internal LCD. Display must be exchanged.

  • Satellite Pro M10 - horizontal lines on the screen in different areas

    Hi all

    I hope someone can help.
    My Satellite Pro M10 seems to suffer a display problem where I have horizontal lines on the screen in different areas.
    It would be well for 10 minutes and when the laptop seems to warm up this problem begins, then shortly after
    The laptop would crash and enter in a resolution of 800 x 600 16 colors or sometimes freeze.

    Graphic drivers have been resettled, and even a new installation of Windows XP from the recovery CD does not help.
    A reboot doesn't solve what the same thing happens again and after one minute of use, so I thought it might be a video or cooling problem.
    I changed the video card I had a spare part of my last motherboard hoping this would solve the problems, but the problem persists.
    Perhaps a cooling problem? Or problems of motherboard?
    The motherboard has been replaced twice, hoping that this isn't another mobo problem.

    Any advice would be great.

    Thank you.

    Hello

    I m not 100% sure but to me it looks a bit like an overheating problem
    Maybe the graphics card may not be properly cooled after a certain period of time and that's why these strange horizontal lines appear on the screen.

    I wonder how you were able to replace the graphics chip on the motherboard?  :|
    If I m not wrong not the chip is fixed and the replacement is very easy and difficult

    It of always difficult to say what's maybe wrong without running several diagnostic tests in most cases this problem may be related to the defective chip or motherboard and so the following should be checked

    Sorry, but that's all I can suggest.

    Best regards from my friend

  • Satellite Pro A210 - repeat vertical lines on the screen

    I hope someone can help me.

    I am a teacher and was bought by my school a Toshiba Satellite Pro A210 for me to do my school work and connect to a SMART board to teach with. Throughout its probably one of the best laptops I got through school. I got it two months.

    There is only one problem with it. Its developed a rather weird problem. Occasionally, the screen suddenly freezes, and the display will be replaced by thin, alternating vertical black and white lines. The only way to get rid of them is to turn off the laptop and restart it (particularly annoying when it happened in the middle of a lesson when I've been respected by an OFSTEd Inspector!)

    Technician computer school has no idea what is the cause. I was wondering if someone here might have some advice.

    Thanks in advance.

    I ve the same laptop but I didn t receive similar lines on the screen.
    What you could do is update the BIOS and the driver (if possible) display.

    If the same problem happens again, you must connect an external monitor to the laptop.

    Then check if the same lines appears on the external display. If so, then a problem of graphics card might be possible!

  • Satellite A205-s4577 - horizontal lines on the screen

    It is also sometimes black or white background just black n.,.
    I contacted the service customer and update the drivers but nothing helped...

    This problem is very common when using ac power supply...
    But it works fine on battery only on first boot it hangs, then works correctly
    A center of service-tech said motherboard disappeared, without it seein juice by the description of the problem...

    Please suggest a solution... m a urgent need for assistance

    Well, I guess this also appears on the external monitor too
    Did you check that?
    Please do

    If the same symptoms would be visible outside monitors so it s GPU related problem I mean the graphics card could be affected and because the GPU is a part of the motherboard, then entire motherboard must be replaced so the tech service guy could be good

    When you do a Reset (reboot) on the iPod

    Learn how to reset your iPod - Apple Support  (see iPod with a click wheel)

    do you see this line on the screen when the Apple logo?  If you do, it is probably a hardware problem.  If the line is not there at the start, but returns after the iPod starts, you can do a restore of the iPod using iTunes.  This d erases the IPO, reinstall its software and sets it to the default settings.

    Use iTunes on your Mac or PC to restore your iPhone, iPad or iPod settings - Apple Support

    If the problem persists after the restore, the cause is likely to be hardware problem.

  • Qosmio G10 has vertical lines on the screen

    I have a G10 which I use for the last 15 months since I bought it.
    However, there are now 4 vertical lines on the screen, 2 Purple (magenta?), 1 yellow and 1 cyan. Other than these lines there are no other problems, it never fell down or something like that.

    The lines are still there, they do not change in any way and are always in the same place. They appear on the screen at first power up, before the Qosmio logo lights up.

    They have not all appear at the same time, they all appeared individually in the past two months. I've seen the last of them disappear briefly, then stay on.

    I guess that my screen is dying slowly, I guess to be an expensive item.

    Any advice thrown my way would be greatly appreciated!

    I took a picture of the screen you will find at:

    Note: the photo was taken with Media Player full screen on a black image, just to clearly show the lines)

    Hello

    I suggest you connect an external display to check if it's a graphics card or a display problem. If cela pipes appears also on the external screen then it could also be a problem with the graphics card.
    If these lines do not appear on the external display while the display of the laptop has a malfunction.
    However, this does not change your situation. I recommend you contact the Toshiba ASP to solve this problem.

  • Qosmio G15: Green vertical lines on the screen

    All started an ordinary day, when I was playing music on my iTunes.
    All of a sudden my screen went black and the music stopped, but my power button is always blue. Since then, whenever I try to start it, it goes on the Qosmio screen and Windows XP screen and plays the startup sound, but there all those green vertical lines on the screen. And then it goes black and tsays in this way.

    I was able to use Windows VGA (whatever that means) with lines all over the screen, but I am not able to start normally. Does anyone have any suggestions or have had the same problem? Please help me!
    I have a Toshiba G15 Windows XP Media Center, but am not able to use it normally.
