Stripes appear on the screen. When repairing the matrix cable yourself, you need to be very careful, patient and careful.

Vertical or horizontal stripes on an LCD TV screen or computer monitor are an unpleasant defect that will prevent you from using the device. Even if they periodically disappear, this still indicates a malfunction of the matrix, cable or circuit elements.

In fact, such a defect on the LCD does not always mean there is a serious technical problem. The simplest reasons for the appearance of a stripe on the screen are:

  • unfaithful picture settings(just run automatic setup);
  • The cables are poorly connected; they may be clogged or clogged with dust.

Vertical or horizontal stripes on the screen due to complex breakdowns can appear constantly or periodically, often accompanied by flickering, “stuck” frames, ripples or geometric distortions of the picture. This malfunction can occur for several reasons:

  • poor connection of the matrix cable (oxidation, breakage);
  • breakdown of the matrix itself;
  • failure of various circuit elements.

Microcracks in the cable

Any equipment is not insured against breakdowns, but in most cases they can be fixed. The downside is that the cost of some spare parts is comparable to buying a new panel - in this case it is better to refuse repairs. First, replace the part does not guarantee complete serviceability, secondly, over time, other components may also fail, then the total cost of repairs will exceed the purchase of a new TV.

If the TV panel was just purchased in a store and has not been used for more than 14 days, it should be exchanged.

It is not recommended to agree to repairs, because there is no certainty that the stripes will not appear again on your TV screen later. IN warranty period You should not carry out repairs yourself; it is more practical to take the TV to a service center. Thus, the user will not lose the warranty obligations assumed by the manufacturer, and will not aggravate the breakdown to a large scale.

Eliminating poor contact

Lines on the LCD TV screen may appear due to poor connection connections. This kind of malfunction is usually the result of poor assembly or improper use of the TV. For example, moisture getting inside the case, which can result from incorrect mechanical shocks. This reason can be established after visual inspection of the connections with the naked eye or using magnifying devices.

Oxidation of contacts on the board

You can clean it off with a blade or knife; it can be easily identified by the green residue, but if the problem is large-scale, then it is difficult to fix it yourself. Afterwards you need to check the voltage or ring the contacts with a multimeter.

Poor contact can be caused by incorrect connection of the cables; to do this, they can be disconnected and reconnected.

Another reason for the appearance of various stripes on the TV display is broken cable wiring. It can be determined by lightly pressing or moving the cable: if the image is restored, then a breakdown has been detected. Eliminating a fracture is a painstaking and delicate process. You need to use a magnifying glass to determine where exactly the wiring is broken. They can be restored by using conductive varnish or heating the contacts to a moderate temperature. Severe overheating will damage all contacts.

Restoration with conductive adhesive

Replacing the cable

In some cases you will have to change the entire matrix cable to a new one. First of all, you need to purchase a new part - it can be ordered at a repair shop, but before that, the year of manufacture of the TV or monitor. You can change a faulty matrix cable yourself or at a service center. For repairs, you will need a certain set of tools: screwdrivers or bits PH, PZ, TORX, HEX, SL.

The connection cable is located inside the case, therefore, it must be carefully disassembled. It is necessary to disconnect the roof, carefully unscrew all the bolts and get to the part itself.

Important to know! The bolts are always standard and unscrew counterclockwise. In addition, many connecting cables and wires can be attached to the cover. When disassembling the TV, you should not make sudden movements to avoid breaking.

Most connections are secured using special connectors, the wires do not have to be soldered. Just press the latch (the connection principle is similar to Internet or telephone cables).

The designs of televisions from different companies, such as Samsung (Samsung), Sony (Sony), Philips (Philips), may differ slightly, so you should use the instructions, or order assembly details on the company’s official website.

Damage to the matrix or its parts

This malfunction is characterized by the presence of a vertical stripe of the same color one to two pixels wide. The defect appears on its own and can also disappear within three to four days. If the problem lasts longer than a week, this is a clear sign of serious problems.

Replacing the matrix is ​​expensive and difficult, so if you have such problems with the image, the solution is to contact the service center if the warranty period has not expired. When an LCD TV has been in use for a long time, repairs can be carried out by specialists from any workshop.

If thin horizontal or vertical stripes of a dark color appear (they do not glow), this most often indicates Column decoder malfunctions, which is located on the matrix itself. Later, the strip will only increase in size, so do not delay your visit to the workshop.

When making repairs or replacing parts, keep the following in mind.

  1. Most conductors have a very small diameter and are easy to break.
  2. Repairing or re-soldering contacts requires skills and special equipment (for example, an infrared soldering iron, magnifying glasses).
  3. All operations are carried out with great care; incorrect movement may result in additional damage.

Vertical stripes on a TV or monitor screen are caused by malfunctions, both minor and global. If stripes appear on the display, but you are not confident in your abilities, you should not find out on your own why a stripe might appear on the screen; it is better to contact qualified specialists. But if you have some knowledge of electronics, then it is quite possible. This also applies to other device failures. For example, it’s quite possible to do it yourself. But if yours, then this may be a sign of a serious malfunction, which can only be determined with the help of special equipment.

Firstly, it is worth saying that stripes may not occur in the following cases: if there is a malfunction in the operation of the video card, if the matrix or its cable has failed. Unfortunately, if in your particular case it turns out that the reason lies directly in the laptop matrix, then it will have to be replaced with a new one. In this case, there are no other solutions to this problem. Repairs should be carried out with the help of specialists at the appropriate service center, and doing this yourself is highly undesirable, since you can damage the new matrix. In order to find out the cause of the problem, you should pay attention to what noise appears on the screen.

How to fix the problem?

If the fault lies in the matrix cable, then you will see multi-colored vertical lines, and if you connect the computer to the monitor using a special cable, these stripes will disappear. A malfunction of the matrix is ​​indicated by the following display parameters: vertical white stripes, the appearance of a black stripe with ripples, and inversion of the image on the screen. In addition, a malfunction of the matrix is ​​indicated by the appearance of black stripes; they are often translucent, and if the netbook takes a certain position, the screen may turn completely black. A malfunction of the video chip is indicated by: interference (artifacts) appearing on the screen in the form of red, blue horizontal lines, or in the form of colored squares, dashes across the entire display, and also if, in similar cases, the image on the external monitor appears without any distortion, and a change in position The screen and its bend do not affect the picture.

Black bars may appear on the screen if your device is equipped with two video cards, for example, nvidia optimus, which have automatic switching, and there is no scaling option in the video card settings. Accordingly, the absence of this item and the scaling itself is the reason for the appearance of black bars. If black bars do not appear while working on the computer or playing games, but appear only when you play back a video, then this means that the problem is with your playback device (video player). In addition, if black bars occur when loading the operating system and during its operation, then you should reset the BIOS settings to standard.

Personal computer users often encounter a black screen while working. It occurs for various reasons, such as hardware problems or problems within some applications.

Instructions

Make sure the video card is installed correctly on the computer's motherboard. Also check whether the monitor is securely connected by checking the connectors on the system unit and the device itself. If the problem is with the video card or monitor, most likely when you turn on the computer you will hear the usual sounds of the system booting, but there will be no image on the display.

Install the latest drivers for your monitor and video card. If they are missing, you may experience a complete lack of image, or an overly blurry or dark picture. Also try adjusting the monitor's image using the function keys located on the front panel. The brightness and contrast settings may be off, causing the image on the monitor to be too dark.

If it occurs when you launch an application, such as a computer game, it may not meet your system requirements at startup. Try pressing the Windows key or the Ctrl+Alt+Del combination to terminate the program that caused the system to freeze, or click on the Reset button located on the system unit.

A black screen can also occur as an acceptable feature of the system in certain cases. For example, while installing drivers for a video adapter, the screen may turn black for a while. The reason for this is the auto-tuning of the system and the installation of the appropriate video parameters. After some time, the image appears on the monitor again. Also, some computer games do not have a loading screen, as a result of which, after starting them, the user may experience a black screen for several minutes. Then the image appears and the game itself begins.

A monitor is the most important device for working with a computer, which allows you to see all the actions on the screen. Unfortunately, the monitor does not always please with its correct operation. Below we'll look at what causes vertical stripes to appear on your monitor, and whether there's anything you can do about it.
As a rule, suddenly appearing vertical stripes on the screen of users’ computers occur for two groups of reasons: software and hardware. In the first case, the software installed on the computer was to blame, and in the second, there were problems with the monitor itself or its connection to the system unit.

A little advice: before you start moving on to ways to solve the problem, try connecting your monitor to another computer - this way you can understand whether the problem is the computer itself, or a malfunction in the monitor.

Software problems

Reason 1: missing video card drivers

If you just reinstalled Windows or updated your video card drivers, but then encountered vertical stripes on your monitor screen, you can assume there are problems with the drivers.

To solve this problem, you will need to install fresh video card drivers. First of all, open the menu "Control Panel" and go to the section "System".

In the left area of ​​the window, click on the item "Device Manager".

Expand the tab "Video adapters". If the name “VGA adapter” or the name of your video card appears next to it, but with a yellow exclamation mark, this indicates that the drivers are not working. If the drivers have been installed, right-click on the graphics adapter and select "Delete".

A confirmation window will appear on the screen, where you will need to check the box next to "Remove driver programs for this device".

Once the removal is completed successfully, you will need to restart your computer. From this moment, you can start downloading and installing the latest version of video card drivers (if you haven’t worked with video card drivers at all after installing Windows, you will immediately need to proceed to downloading them, without the preliminary removal procedure described above).

You can download video card drivers from the official website of the manufacturer of your graphics adapter (specifically for your model). If you are the owner of a laptop, then the graphics drivers will be downloaded from the laptop manufacturer’s website.

After downloading the required driver distribution, you will need to run it by installing it like any other program, and then be sure to restart the computer.

Reason 2: incorrect resolution settings

The problem with vertical stripes may arise because the computer settings are set to the wrong resolution.

To check this, right-click on any free area of ​​the desktop and select the item from the context menu that appears. "Display Options".

Please note that further actions are discussed using Windows 10 as an example. If you have a different version of the operating system, the name and location of the settings may be different.

In the settings window that appears, click the button "Advanced screen options".

Hardware problems

Reason 3: video card failure

If possible, connect your monitor to any other computer. If the vertical stripes have disappeared, but you do not suspect software problems, you can assume that the problem lies with the video card, which may have failed.

Next, you will need to disconnect the video card from your computer, and then insert it into another computer that you are completely confident in its functionality. If the situation with the monitor is similar, you have once again confirmed your guess.

In this case, you will need to try to visually inspect the video card to see if it is covered in dust, and if the contacts are dirty. If the problem is in the contacts, clean them with an eraser and also get rid of all visible dirt. After this, the video card did not work? Then you will not be able to help it in any way: either contact a service center to have it repaired, or replace the video card.

Reason 4: Incorrect monitor connection

Check whether your monitor is connected to the computer correctly: the cable connecting the monitor must be fully plugged in on both sides. We recommend that you additionally use a different outlet for the monitor - it is quite possible that it simply does not have enough power.

If there is any type of damage on the connected cable, the cable must be replaced.

Reason 5: Motherboard failure

A sudden power surge, severe overheating, or a simple manufacturing defect can cause the motherboard to fail.

In this case, of course, if you connect the monitor to another computer, it will work fine. Except for problems with the video card, you should suspect the motherboard - and here everything is already sad, and you won’t be able to help it on your own; you will definitely need to contact a service center (and the sooner the better).

Reason 6: Monitor malfunction

If on other computers the monitor still produces the same reaction with vertical stripes, we can assume that the problem lies in the monitor itself.

Alternatively, try pressing on the top of the monitor with your finger - if the stripes disappear, this may indicate that the cable in the monitor is coming off the matrix body (but this step may not have any effect).

In this case, you will need to take the monitor itself directly to a service center, where they can more accurately diagnose and solve the cause of the problem, or try to disassemble it yourself (of course, if you have at least some experience). If the problem is insufficient contact of the cable with the matrix body, you will need to use something to seal the gasket at the exit point.

As a rule, these are the main reasons for the appearance of vertical stripes on the monitor.

Technical equipment, new technologies, subtle but unnecessary interconnection of various elements - this is what modern progress has come to. We are, of course, talking about a computer, which has a lot of elements that require care and careful monitoring so that they work correctly and do not break. But not every one of us can do this, so we are faced with various problems that sometimes manifest themselves very strongly and cause a lot of inconvenience. We will mainly talk about technical problems that are difficult to diagnose, but it is quite possible to fix them yourself. And in this article we will look at where and why stripes appear on the monitor, which sometimes overshadow the entire picture on the screen. Fortunately, the problem is not always critical, so in most cases you can fix it yourself. And sometimes they indicate that the equipment has broken down and urgently needs to be replaced.

What is this problem?

Before you figure out where they came from on the monitor, it’s worth considering the problem itself, which in most cases is of a technical nature. Yes, a program failure, a virus and other problems, even an option related to drivers - none of this is the reason why defects appear on the monitor screen. This problem is a consequence of the negative influence of computer elements on the monitor or their incorrect interaction with each other. The problem is simple and critical, but this will become known only after a thorough diagnosis of the equipment. When this unpleasant situation occurs, various defective stripes begin to appear on the monitor, which bring with them a lot of trouble. Either they completely obscure the entire monitor, or they replace the colors, or the screen completely disintegrates into pixels.

Why does it occur?

If stripes appear on the monitor, this means that it is time to diagnose all equipment. You shouldn’t blame everything on the video card in advance, since it is not always the main cause of the problem. There may be other parts of your equipment involved that may contribute to this defect. It is worth completely excluding options that relate to programs or driver failures, since image distortion, which is also filled with extra stripes, is guaranteed to be a technical problem. Therefore, you can safely turn off your computer and start checking all your equipment for damage, dust, and much more.

Main causes of this problem

Vertical or horizontal stripes on the monitor may appear due to hardware failure or overheating. The incorrect interaction of various technical elements should also be taken into account. In addition, do not forget that the source of the problem can be dust and contamination of the cables, which are the connecting connection between various elements. Therefore, in order to establish the true causes, you need to conduct a series of diagnostic studies that will identify the true problem, and only then think about ways that will help get rid of this unpleasant situation. And it’s worth remembering that you shouldn’t immediately run to the service center, since in most cases you can get out of this situation with your own efforts. Well, if a technical problem is classified as critical, then there are no options - you will have to find among your friends those who have experience in troubleshooting such problems.

Video card

Horizontal stripes on the monitor and any defects in general cannot be caused primarily by a faulty video card. It is necessary to check whether it is working normally, whether the cooler on it is dusty, which can cause overheating of the equipment, and whether it is connected to the motherboard correctly, that is, whether the wires are damaged. Yes, the video card is the image processing center, which can cause the problem. Therefore, if you suddenly notice that the board itself is working normally, you should definitely clean it of dust using cotton swabs. Then check its connectors and try to clean them. After this, check the wires for physical damage. If it doesn't exist, that's good news; If the wires are damaged, then the equipment will need to be replaced.

If no problems are found and everything is cleaned, it is worth carrying out another check, which consists of examining the technical features of the video card. It sounds complicated, but in reality everything is simple: you need to check the equipment on another computer. A friend can help you with this: just insert the video card into his computer and check if there are stripes on his monitor. If there are no stripes, then the problem is different; if there is a defect, then the problem is in that graphics hardware. This means you should contact service or buy a new video card.

Monitor malfunction

When vertical stripes appear on your monitor, do not panic. Just start checking your equipment. And it’s worth noting right away that the option with a monitor is also appropriate, although this element is not programmable. Any physical impact on the monitor can cause a lot of problems regarding image deformation. You can also note factors such as exposure to sunlight and exposure to high humidity on the monitor. To test this device, you do not need special education; you just need to test it on another computer. Take advantage of this opportunity from a friend. If after connecting the bars on the monitor disappear, then the problem is in your computer; if the opposite result occurs, then you need to contact a specialized service, since such a problem cannot be corrected with your own hands.

Checking loops

Stripes can also mean that you probably have problems in the connections of the elements themselves, which can sometimes be either physically damaged or simply dusty. To check them, you need to carefully examine every millimeter of the cable for physical damage. Are there blackheads there? Is the cable itself positioned correctly? Does it have unnecessary bends? Is everything connected correctly? If this is possible, then it is worth checking them on another computer. In fact, the problem of cables is quite complex, and not everyone can fully check these wires, therefore, in order to diagnose such a problem instantly, you must always have several spare cables on hand, which can be replaced if necessary. If, after using fresh wire options, stripes continue to appear on the monitor, then you should look for the source of the problem in other equipment. And if there is no problem, then you have already solved it and can continue to enjoy the possibilities of the virtual space. It is worth remembering this nuance, since not many people know that this can also be the cause of an unpleasant situation.

Cleaning your computer

Damage to internal elements

But do not forget about the possible breakdown of internal devices, which can also cause defects on the screen. These elements mainly include traces and connecting elements on the motherboard. If you check them carefully, you will find that some of the strips have turned black and the resistors are swollen. It is this state of affairs that is the cause of the breakdown, which cannot be corrected by one’s own efforts. Therefore, if you find at least one of the elements listed, then you should replace the motherboard, since repairing it will no longer be possible.

How to solve this problem?

Stripes appeared on the monitor. How to solve this problem? Actually, we examined all possible solutions in this article, all of them are described above. First, you need to diagnose the equipment, clean the computer, since dust can cause overheating of important computer elements, and then draw conclusions and look for a way out of this unpleasant situation. A vertical stripe on the monitor or another graphic defect - all this is caused by the problems that we have discussed. As for the ways to eliminate them, we also examined them, in particular we mentioned the motherboard itself, which can serve as a source of negative impact. But, unfortunately, it is quite difficult to check it, so the only correct solution may be to contact a service center. Everything else can be checked and you can figure out what exactly is the reason for the defect appearing on the screen.

Service - guaranteed solution to the problem

A black line on the monitor, the image breaking up into pixels of different sizes, the image disappearing, incorrect color gamut - all this and much more indicates that there is a problem with your computer. This article allows you to fix them or diagnose them yourself. But it happens that your hands are simply afraid to touch anything there and generally disassemble the computer. It is in such cases, when you are not confident in your abilities, that a specialized service center will help you, where they will provide all the necessary services. For a fee, they will clean your computer and restore the normal image on the monitor. And if the breakdown is critical, then they will definitely tell you what exactly the problem is and how to fix it. Now it has become much easier to navigate this situation, which will undoubtedly serve as a positive new experience in terms of managing and monitoring computer technology.

Color stripes on the monitor are one of the most characteristic signs of a device malfunction. They usually appear immediately after turning on the PC and look different:

  • Colorful stripes of different widths, similar to the northern lights, which completely block the image on the monitor.
  • Pink, purple, blue or yellow vertical stripes on the monitor screen, alternating with normal areas and located at the same distance.
  • appeared on the monitor screen red, blue or green stripes, located horizontally or vertically and occupying the entire surface of the screen or individual rectangular areas. As a rule, the image in these places is distorted.

  • Thin ones are visible gray stripes on the monitor.
  • Appeared wide white stripe, occupying more than half of the total area on the monitor.

These are the most typical cases of monitor malfunction, which can have many more combinations and options. However, color stripes on the monitor themselves are a serious reason to think about repairs, because even barely noticeable stripes are harbingers of a major breakdown that can completely damage the monitor.

What to do if color stripes appear on the monitor?

Typically, the appearance of stripes on the screen is associated with a broken video card or an incorrectly working driver. However, if all components of the PC system unit are known to be in good working order, then we are talking about a serious problem in the design of the monitor itself, which cannot be eliminated without the help of a specialist.

Most often, artifacts in the form of multi-colored stripes on the screen are caused by a direct breakdown of the monitor matrix. This may be the result of a power surge, mechanical damage, or ordinary wear and tear. In this case, the problem is solved by replacing the matrix.

The cable connecting the matrix and the video controller on the control board, or the electrodes powering the screen pixels, may also fail. Often, colored stripes appear on the monitor screen when the video signal is poor due to dusty or damaged contacts.

Below are some typical cases associated with multi-colored stripes on the monitor screen and possible reasons for their appearance. Please note that the description of the problem does not take into account the performance of the video card. It should also be remembered that the described malfunctions are not the only possible ones.

Reasons for the appearance of stripes

Signs and probable malfunctions

Rectangular areas consisting of a cluster of short, thin vertical or horizontal stripes of red or green.

The video signal contacts may be dusty or damaged, the tracks on the control board have peeled off, or the video controller cable or VGA wire may be damaged.

Wide white stripe occupying a third or more than half of the screen surface.

Most likely, the matrix has failed. Needs replacement.

Yellow vertical bars spaced evenly across the screen.

If the problem periodically disappears and appears, the matrix decoder conductors may become detached.

Wide purple or pink stripe on the monitor.

The matrix controller is probably faulty. The problem is often observed on new monitors and may be the result of a manufacturing defect.

Thin vertical stripes of blue or light blue.

One of the cable contacts or the video controller may be damaged.

Light flickering stripes that are barely noticeable on the screen.

The problem may be due to a faulty VGA cable or a low-quality surge protector powering the monitor.
