Here’s one more example of a faulty LCD screen. Long story short, I had to replace the system board and it fixed the problem. I guess it happened because the system board had some kind of intermittent problem with onboard video or video connector. But the reddish video appeared again as soon as I replaced the screen. Yes, for some reason I wasn’t able to reproduce the problem on my test LCD screen. The problem disappeared when I installed my test LCD screen. Reseating and replacing the video cable didn’t help. My bad! It wasn’t the LCD screen problem.Īs soon as I turned on the laptop, I was getting these reddish marks on the LCD screen but not on the external monitor. Here’s another example of a bad LCD screen. (We do not have equipment to replace the memory module itself). To fix the problem, I’ll have to replace the board. In Toshiba Satellite 5205 the video memory is integrated into the system board. I’ve tested the video memory with Microscope utility and it failed the test. In this example, the vertical lines were caused by a failed video memory on the system board. On some laptops the video card is integrated into the system board, on other models it’s a separate module. When the same video defect appears on both monitors – internal LCD screen and external screen, then most likely it happens because of a bad video card. The same pattern appears on the external monitor. Sometimes these lines are red, sometimes they are blue, sometimes they become wider and change color to white. The laptop displays identical vertical lines all over the LCD screen as soon as I turn it on. The photo below comes from Toshiba Satellite 5205. My laptop was fixed after I replaced the LCD screen. I’ve never seen this kind of video output caused by a bad video cable or bad FL inverter board. Unfortunately, these lines indicate a screen problem. A video output on an external screen would be perfect, without any lines. When you move the LCD screen some lines might disappear or more lines appear on the screen. One day you wake up, turn on the laptop and see one or a few hair-like vertical lines in different colors. I think that this example is very typical. I took this picture from Toshiba Satellite M65. Reseating the video cable didn’t make any change and the problem was fixed after I replaced the LCD screen. When I torque the screen, the image appears but it’s distorted with some horizontal lines running across the screen. Some horizontal lines appeared in the middle of the LCD. The external monitor worked fine.Īs soon as I applied some tension to the screen it changed the pattern. To me it looked like Northern Lights (never seen in real life) :). There were a lot of vertical lines, and they were changing color without any pattern. I got this video output as soon as I started the laptop. Were you able to fix the screen flickering on Windows 10? Did you use a different method? Tell us in the comments below.Here’s a picture of Satellite M55 LCD screen I made this morning. If the previous version is working on your computer, you can temporarily prevent the operating system from updating a particular driver. The caveat installing an older version of the driver is that Windows Update may try to replace it with a newer version. While you may miss out on new improvements and features, sometimes an older version of the driver may work better on your computer. In case the latest driver doesn't fix the flickering problem on your computer, as a last resort you can try to download and install an older version of the driver from your manufacturer's support website (if available). Here's a list of the most popular support sites to download the latest video drivers: Alternatively, instead of using Windows Update, you can download and install the required driver manually from your graphics card manufacturer's website - of course, you'll need to know which graphics card is installed in your computer, which you can find by looking up your system information. Windows Update always delivers the most compatible device drivers, but it doesn't mean that they're the most recent version available.
