Vertical bar on the laptop screen

A laptop differs from a computer in more portability, convenient size and no need to connect other devices for everyday use. But finding the cause and fixing the damage is more difficult than on the computer due to the nature of the device. Both the monitor and all system elements are closely interconnected, and in most cases there are several alleged causes of almost identical malfunctions.

Causes of vertical stripes on the laptop screen

The appearance of bands or noise on the screen - a common failure, which over time can progress and occupy an increasing area on the screen. Such bands interfere with color reproduction and text perception, distract from work or when viewing photos and videos.

  • Overheating or a complete breakdown of the video card is one of the most common causes. Usually, with this phenomenon, the stripes on the monitor are colored, often there are ripples and kinks of straight lines. In the case of overheating of the video card, distortions appear at the initial stage of loading the laptop when it is turned on. Over time, the screen may stop working completely;
  • Problems with the motherboard - the problem is quite rare and requires the intervention of a specialist. Usually, in case of failure of the board, all laptop systems are damaged, but there are cases where failures affect only the elements responsible for displaying the image;
  • Damage or malfunction in the work of the loop - the element transmitting the signal from the main process to the laptop monitor. The loop from the motherboard goes straight to the display. According to its length, it may be damaged, pinched or melted. Bands on the screen can also appear as a result of poor contact at the points where the cable is connected to other system elements;
  • Breakdown of the monitor matrix. The screen of portable devices is particularly fragile, even one careless abrupt closure can lead to malfunctioning of the matrix and the appearance of bands;
  • Problems with drivers and software.

How to get rid of the bands

If the bands on the monitor make it difficult to work or their number and size grows, you should contact an experienced master for professional diagnostics and repair. But with the breakdowns described above, the repair will be quite expensive. In order not to become a victim of unscrupulous masters and to save your budget, an attempt to diagnose yourself will not be superfluous.

In order to immediately eliminate the malfunction of the matrix or cable, you can connect an external monitor to your laptop. If the image is displayed on it without interference, then, most likely, the problem is different. You can also try pressing on the screen or gently trying to bend it or close and open the laptop at different speeds.

Reference! If, with such manipulations, the number and location of the bands change, then the problem lies in the matrix or loop.

If, when an external monitor is connected, the same bands appear on it as on the laptop screen, then the problem lies deeper and is connected with the video card or motherboard. To solve this problem, you must have the skills and experience of repairing such devices. Otherwise there is a risk only to aggravate the situation.
