Stripes on laptop screen

When working on a laptop, the user quite often has to deal with various damage to the display. These can be horizontal or vertical stripes of rainbow color that stretch across the entire monitor, ripples (in some area the image is distorted as if water was dropped), a decrease in picture clarity, or a portion of the screen turning off. These signals indicate problems within the computer.

Causes of problems

There may be several reasons why streaks appear on your laptop screen. Each of them provides its own solution.

Video card. Problems with the operation of the video card can cause a variety of noise on the screen, because due to this element the user sees everything that the computer is going to show him in its interface. If the picture suddenly becomes fuzzy, blurry, too shaded, or, on the contrary, light, with insufficient contrast, or some colors begin to be replaced by others, the problem is precisely the architectural element.

Just in case, you should check the operation of the video card. Most often, a white or gray stripe appears. To do this, you need to try installing another video card in your laptop, which is known to work on other devices. If the stripes have disappeared, it means that the part being replaced is damaged.

A video card becomes unusable primarily due to overheating - it deteriorates completely or is simply unsoldered (the second case occurs only when the temperature of the processor and the entire motherboard rises to unimaginable heights, and the cooler is not able to cool the system).

Plume. A laptop cable is a group of wires connected by a single rubber plate, which provides a connection between the screen (cover) and its lower part, where the architecture is located. Due to the constant dynamics of the two halves of the mini-computer, the wires fray, which is why the signal becomes unclear, the image may disappear, be covered with stripes, darken, or not appear immediately. Often a situation may arise when it is possible to see something on the monitor only when the cover is in a certain position, when the contacts are pinched together and information passes through.

During factory assembly, the cable is positioned as much as possible so that it is damaged as little as possible when working with the device. But if the laptop was disassembled at least once and, accordingly, put back together, then there is a high probability that, due to assembly, the wires were positioned incorrectly, bent and the signal stopped passing correctly, which led to the appearance of stripes.

Matrix. The matrix is ​​what is located under the protective glass of a laptop monitor. Partial damage to it often causes streaks to appear on the screen. To check whether the matrix is ​​working is simple - connect an additional monitor and look at the picture that is displayed on it. If there are no failures, then the problem really is with the matrix.

In addition to the above, the reason for the incorrect display of the image on the screen may be failures on the motherboard or incorrect image settings.In the second case, to solve the problem you just need to adjust the picture settings, and the conflict will go away by itself. The motherboard may melt due to the same overheating. This happens rarely, but if all other reasons are not found, it means that the motherboard is to blame for the stripes.

How to remove stripes

Solving screen problems, preventing streaks on your laptop monitor for each of the reasons:

• Problematic video card. The solution here is simple - purchase a new architectural element and carefully install it. Even if the card was simply unsoldered, irreversible changes could have occurred in it due to the high temperature, or it could simply have worn out during operation, so you shouldn’t mess with it, but it’s better to update it right away.
• The train bends. In the case of interruptions on the way from the processor to the display, there are options for the development of events:
  • o Disassemble the laptop and adjust the cable so that it does not bend. It will help if the device was disassembled earlier and the wires were incorrectly placed inside and later, due to work on the computer, there was no irreversible damage to the contacts, only the insulation was dented.
  • o Buy a new one. This case is suitable if one or more wires have been broken or frayed so that the signal does not pass through at all, or passes through intermittently. If there is visible damage, it is necessary to replace the combiner with the same one - of the same manufacturer and model.
• Matrix destruction. It is impossible to repair this part yourself, only replace it. You can find a wide selection of laptop screens on sale. In order to purchase the right one, you should search by the model name of your device and the number of pixels (1080x1024, for example).
• Motherboard.Considering that this element is often integrated, if the “mother” is destroyed, you will have to look for a new laptop, or put up with stripes on the display as long as possible.
