Some laptop users have found that their laptop screen has one or more vertical lines. Sometimes moving the screen can clear the lines, but once you stop moving, the laptop screen lines will reappear, while some screen lines will always exist. In fact, the laptop screen has flickering lines may be caused by software problems or hardware problems. However, whether why it is happened, you can try to judge and fix the screen problem yourself.
1: Make sure if the Screen Lines is caused by software or hardware
Operation method: Firstly, you are required to restart your laptop and press the function key to enter your computer's BIOS settings. The key that enters the BIOS depends on the manufacturer of the laptop, which you can find in the laptop user manual, or you can Google search for it.
After entering the BIOS interface, if the screen lines appearing, means the problem is related to the software. If you still can see the flickering lines, it is probably the hardware problem of the laptop motherboard, screen cable or the laptop screen.

3: How to repair hardware for laptop screen all lines?
1.Detecting the motherboard
Connect an external monitor to see if it has the same problem, and if so, the motherboard is broken. Otherwise, you should check your screen cable and screen.
2.Detecting the screen
If the external monitor displays properly,run LCD BIST (Build-In Self-Test) on the laptop to check the LCD screen.
To activate the LCD BIST, please do the following:
1)Connect the AC adapter to your computer.
2)Hold down the letter < D> on the keyboard and power up the computer. You will see four colors (gray,red, green, and blue) in turn on the screen.
3)If you see no distortion on the screen, the LCD screen is fine. If multi-color vertical lines are found in the test, then it can be judged that it is a problem with the laptop screen, and the screen must be replaced.
3.Detecting the cable
As using time goes on, the screen cable may wear out or even crack (especially at the hinge, because the laptop screen cover will be often opened or closed), causing horizontal and vertical laptop lines.
The cost of buying a new screen cable is usually not too high, and you can buy it for about $5 and replace it by yourself.
