Fixing bad video on LCD screen. Here Im going to post some laptop screen photos showing bad video output. Ill explain what was wrong with the screen and how I fixed it.

Hewlett Packard Reflash Driver' title='Hewlett Packard Reflash Driver' />I got this video output as soon as I started the laptop. There were a lot of vertical lines, and they were changing color without any pattern. To me it looked like Northern Lights never seen in real life. The external monitor worked fine. As soon as I applied some tension to the screen it changed the pattern. Some horizontal lines appeared in the middle of the LCD. Heres the difference.

Reseating the video cable didnt make any change and the problem was fixed after I replaced the LCD screen. Example 2. I took this picture from Toshiba Satellite M6. I think that this example is very typical. One day you wake up, turn on the laptop and see one or a few hair like vertical lines in different colors. When you move the LCD screen some lines might disappear or more lines appear on the screen. A video output on an external screen would be perfect, without any lines. Unfortunately, these lines indicate a screen problem. Ive never seen this kind of video output caused by a bad video cable or bad FL inverter board. My laptop was fixed after I replaced the LCD screen. Example 3. The photo below comes from Toshiba Satellite 5. The laptop displays identical vertical lines all over the LCD screen as soon as I turn it on. Sometimes these lines are red, sometimes they are blue, sometimes they become wider and change color to white. The same pattern appears on the external monitor. It displays same vertical lines. 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 Back Pearl here. On some laptops the video card is integrated into the system board, on other models its a separate module. In this example, the vertical lines were caused by a failed video memory on the system board. Ive tested the video memory with Microscope utility and it failed the test. In Toshiba Satellite 5. To fix the problem, Ill have to replace the board. We do not have equipment to replace the memory module itself. Example 4. Heres another example of a bad LCD screen. My bad It wasnt the LCD screen problem. As soon as I turned on the laptop, I was getting these reddish marks on the LCD screen but not on the external monitor. Reseating and replacing the video cable didnt help. The problem disappeared when I installed my test LCD screen. Yes, for some reason I wasnt able to reproduce the problem on my test LCD screen. But the reddish video appeared again as soon as I replaced the screen. I guess it happened because the system board had some kind of intermittent problem with onboard video or video connector. Long story short, I had to replace the system board and it fixed the problem. Yep, I misdiagnosed this laptop. Example 5. Heres one more example of a faulty LCD screen. The left half of the screen works just fine but the right side is completely white. Example 6. Heres another laptop with a bad LCD screen. This time its a tablet PC. Example 7. This screen looks like the screen on the example 1. I hooked up an external monitor and the external video works perfectly fine. Heres the difference. When I torque the screen, the image appears but its distorted with some horizontal lines running across the screen. After a few seconds the image washes away. I had to replace the LCD screen. Example 8. This laptop displays inverted colors right from the startup. As you see, the Toshiba logo is light green instead of red. The background is light gray instead of black. The Intel logo should be blue on a white background but it is red on a black background. When your laptop displays inverted colors as on the picture above, this is an indication of a bad screen. Youll have to replace the screen. Example 9. Here are two more screens. In both cases this problem is related to the LCD screen, witch means the screen has to be replaced. On the image below you see a white band running from the top of the screen to the bottom. This band appears right from the laptop startup and runs through the logo too. On the following image only the left side of the screen is working properly. This problem is caused by faulty LCD screen.
