There are red lines throughout the screen on my Pavilion dv7-1240us laptop

Pavilion dv7-1240us, windows vista 64-bit, without updates to the system

There are red lines throughout the white background screen, it's very annoying. I was wondering if it could be the graphics card or is there a fix for the firmware/software that can be done to correct this situation. Everything seems to not work properly

You are welcome.

    I agree with Richard. There's probably graphics card failure. If the same behavior occurs during the starting procedure, the graphics card must be exchanged. I mean the motherboard together. ;(

  • Yellow dots and two lines on the screen

    My computer shows the points of color on my screen which vary according to the background color and are mostly yellow. There are also lines on the screen that disrupt the display. The problem is not with the monitor, and I do not think his material. I had this problem before, which then developed into my computer crashes when starting each time, and someone managed to fix it for me when he reinstalled windows. It worked very well, but the other day I started a demo to the steam and the messed up display as soon as it is loaded. I tried to reinstall windows to see if it works, but the problem persists.

    My system is running a processor intel E6750, a Radeon HD 2900 XT 4 GB of RAM and Windows Vista 64-bit

  • The HP Omni100 5155 PC: HP omni100 5155 red and green lines on the screen

    I used a music cd in my pc one day and the next day I had thin green and red, vertical lines throughout the screen. I did a number of bugs, but the problem persists. I was wondering what I need to do or it sounds like a graphics card? Although I checked it and the message says: "the device is functioning properly."

    I tried the things:

    • updated drivers
    • scanned for viruses
    • cleaned the ram
    • memory diagnostic tool
    • update graphics card

    Sorry, for obvious reasons, I'm not here to sell you a computer.  Most of the all-in-one computer today have the specifications you are looking for, except perhaps the webcam integrated according to the model.  You can see the HP, Amazon or Tiger Direct store as examples.

    If you are looking to buy the same more or less the same model as you have now, they are abandoned or not available unless used or refurbished which I would not recommend it.

    Before doing something drastic, discover the repair costs to the one you have now.

  • 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

  • The very low vertical lines are coming up on the screen in 4 or 5 places on my KDL-65HX925

    The very low vertical lines are coming up on the screen in 4 or 5 places on my KDL-65HX925. Sony India assistance team is subscript, but to change the Panel also did not help.

    Now the expensive game is with the service center for over a week and they refuse to return the whole and execution of R & D with no idea. In India, it is better not to go for the set bonus from Sony because they are not able to provide support.

    But people do you have any idea what is the cause?

    I'm sorry to hear what is happening with your TV. Only a technician can diagnose what's wrong with your TV. Unfortunately, we are unable to help customers outside the United States. I suggest that get you in touch with Sony India help on this issue.

  • Red line on desktop screen

    Recently I noticed a "red line on desktop screen", running from the top of the screen to the bottom of the screen. The laptop works fine, no problem. Do know you if this "red line" can make me evil or eny one using the laptop, please thank you

    There she is in all programs, so if you start in Safe Mode then it is probably a hardware rather than a software problem. If it's a hardware problem, you will probably need to get your professionally repaired laptop because they are difficult for individuals to work on.

  • 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 G10 begins with vertical lines on the screen

    Hello, can anyone help?

    When I try to start my sign qosmio G10 comes on with vertical lines on the screen. And the screen goes black and I can only hear the fan.
    In VGA mode, it begins upward, but always with the lines on the screen.
    Is there something wrong with the video card? In my view, that there are more people with this problem.
    Toshiba offered little help?

    I'm 'out out of warranty '. I need to by a new complete motherboard or y at - it another option? Replace the video card?

    Hello

    Its a shame about the warranty because you ask the service partner Toshiba for the verification of the laptop and this procedure would be free. You know, the warranty would cover the audit of the laptop.

    But I would say the external display connection and then you can check if the same vertical lines appear on the external display.
    If you see the lines on the second monitor, then I guess it could be something wrong with the graphics card or motherboard.

    I think that this procedure is the best way to find out what could be the problem, but anyway, I think you should ask a technician for assistance if you want to solve this problem.

    PS: Have you tried to reinstall or update the graphics driver? I think you should do it but I don't know if it will help you, but you know Mr. try is free ;)

    One of my friends had a similar problem with the vertical lines on other mobile manufacturing, and it was a WLan cable which was responsible for the strange lines on the screen.

  • Solid black line on the screen of the HP Tablet

    I just got this HP 7 5709 flow. So far so good except there is a horizontal black line across the screen. I first thought, this is the screen protector, but now I'm starting to think that it is in the screen itself. Is - is this known? Attached to the image here. Thank you

    all kinds of lines on the screen that persist all the time are defective LCD screens and will need a replacement.

  • 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

    There are horizontal white lines on the screen as soon as I start it... it hangs at any point n that get these lines.
    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
