The appearance of a vertical strip on the monitor is a common problem. Provoke it may be different reasons that can be detected by doing some manipulation. Consider the color of the strip, which can be black, white or color.
Why do vertical stripes appear on the monitor screen?
To obtain a picture, a graphic chip is needed on the display, which is placed separately on the video card or integrated into the central processor. The information from it through the loop is transmitted to the screen, and the motherboard controls the system. Proceeding from this, it is possible to single out the reasons why vertical lines appear on the monitor:
- Rarely the problem lies in the malfunction of the motherboard, since this part is practically not subject to damage. The board is out of order more often due to the existing marriage, after a short circuit, a power surge and due to other problems. In addition, it should be noted that with the failure of the motherboard, only the bands are rarely shown, as there are other failures.
- If vertical strips appear on the monitor, then often the reason lies in the video card, the breakdown of which is associated with the degradation of the chip due to overheating.
- For transferring images in laptops, a loop or cable connected to the motherboard and to the display is used. If this part is pinched or damaged, bands appear on the monitor.
- The most common reason concerns the failure of the matrix. It should be borne in mind that the screen on the laptop is very fragile and when the device is sloppy, you can damage the matrix.
- Rarely, but it is possible for the bands to appear on the monitor due to drivers, so the first thing to do when stripes occur is to reinstall the "firewood".
Vertical pink band on the monitor
In most cases, multi-colored stripes on the screen have a connection with the breakdown of the matrix of the monitor. This can occur as a result of failures in the power supply system, falls, shocks and other similar impacts or wear of parts. If there is a vertical band on the monitor, which is painted in pink or purple, then this usually indicates a fault with the scanner. The appearance of such a defect can be observed on new monitors, and everything is in the factory marriage.
Vertical white bar on the monitor
White, like any other color of the bands, more often indicates problems in the work of the matrix. If, with a slight pressure or other influences on this part, the interference disappears and appears again, this indicates the need to replace the part, since it has already failed. When vertical bars appear on the computer monitor screen, which are barely visible and flicker, then this may be due to a malfunction of the VGA wire or the mains filter that supplies the monitor.
Vertical blue bars on the monitor
Many users after a long game, when the technique overheats, or the video card is working on wear, notice that on the monitor screen appeared vertical bands of blue. In this case, if the warranty remains, the video card should be replaced. There is another reason for the appearance of vertical blue or blue stripes - possible damage to one of the matrix loop contacts or the detachment of the video solder balls from the BGA substrate due to overheating.
Yellow vertical bar on the monitor
To determine the cause of the failure, you need to perform some manipulation. If a vertical strip appears on the LCD monitor, then disconnect it from the system unit and plug it into the network. In case the band disappears, there are problems in the operation of the video card, so it is necessary to check the cooling system and install new drivers. If the bands are left, then the defect is related to the display. When a vertical strip of yellow color or other shade appears on the monitor, you should see if there are any condensers on the video card and replace them.
Vertical red band on the monitor screen
There are users who complain that there are distortions from time to time on the screen. If you are wondering why the vertical stripes of red appear on the monitor, then it is worthwhile to know that often it's all about the bad contact of the matrix loop. Rarely, the problem can be caused by the combustion of elements. Areas of rectangular shape, consisting of vertical bands - a signal about dustiness or damage to the connectors of the cable connection. Other reasons: there was a detachment of the track on the control board or a damaged video controller cable or a VGA wire.
Black vertical bar on the monitor
According to reviews on the screen sometimes seen black bars, which can be located in different sides and even in the center. A thin vertical bar on the monitor appears if there are failures or breakdown in the operation of the video card, matrix or its loop. If it was determined that the whole thing is a malfunction in the matrix, then the problem will not be fixed and the only solution is to replace the part.
Vertical bands appeared on the monitor - what to do?
Actions to detect the bands will be directly related to the cause that caused the failure:
- First, we'll figure out how to remove the vertical bar on the monitor if the video card is faulty. First, check the quality of the cooling system, for example, run a special program that determines the temperature. Disassemble the computer and remove the accumulated dust and replace the thermal grease. For laptops, use a stand with additional fans.
- If the problem occurs due to a faulty motherboard or cable, it is better not to experiment and do not try to fix the failure yourself, so as not to aggravate the situation, so take the monitor or computer for diagnosis to the service center.
