Stripes appear when you tap on the screen. We remove horizontal stripes on the monitor screen that suddenly appeared

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 system unit PCs are known to be in good working order, then we're talking about 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 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.

Listed below are some typical cases associated with multi-colored stripes on the monitor screen and possible reasons 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 poor quality surge protector, powering the monitor.

Vertical or horizontal stripes on a TV screen with an LCD display or a computer monitor - an unpleasant defect that will not allow you to use 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 the presence of a serious technical problem. Of the most simple reasons The appearance of a stripe on the screen can be distinguished:

• 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 may appear constantly or periodically, often accompanied by flickering, “stuck” frame, 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 various elements scheme.

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. So, the user will not lose warranty obligations, which the manufacturer undertakes, 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. Install this reason maybe after visual inspection connections with the naked eye or using magnifying instruments.

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 on new. 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.

It is 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).

TV designs 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 there are similar problems with the image, the solution will be to contact the service center, if not completed guarantee period service. 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.

Such breakdowns are classified as complex, and their elimination requires the intervention of a qualified specialist. Streaks on a laptop screen are a fairly common problem that is almost impossible to deal with on your own. It is relevant not only for a laptop, but also for many other mobile, digital gadgets equipped with liquid crystal LCD displays.

Horizontal and vertical stripes on the screen

The cause of such problems can be both software and hardware problems, namely:

matrix failure;

damage to the cable connecting the matrix and the motherboard;

faulty video card chip;

failure of motherboard components.

The most in a simple way make an initial diagnosis is to connect external monitor. If the image on it does not have defects, stripes and so-called artifacts, then most likely the problem lies in the laptop matrix or a faulty cable. If banding and image distortion are also observed on the external monitor, probable cause the breakdown lies in a faulty video chip or other important components of the motherboard.

You can also check the proper operation of the matrix by mechanical action, pressing your fingers on the surface of the screen or closing and opening the lid several times. If the horizontal or vertical stripes begin to change, then the problem lies in a faulty cable and a damaged matrix.

If any of the above cases occur, the prognosis is disappointing. However, only an experienced specialist can make an accurate diagnosis. service center.

Problems with cable on laptop

The cable connects the screen matrix with motherboard. Due to the fact that part of it passes where the laptop lid is folded, the cable is subject to gradual wear, and over time this leads to broken wires and contacts. The likelihood of such a problem occurring does not depend on the features, intensity of use, design and brand of the laptop manufacturer. Even careful use and careful opening and closing of the lid do not guarantee that the cable will last forever. The manufacturer puts a certain resource into the part, after which it requires repair or replacement.

Before proceeding with the replacement, the technician must diagnose and identify the problem. One of the main symptoms that indicate a faulty cable is image defects, vertical and horizontal stripes that occur when the cover is opened/closed or is in a certain position.

Repairing a laptop screen cable is a fairly simple and inexpensive procedure; the most important thing is to find a high-quality, preferably original, part.

Malfunction of the matrix itself

The matrix is ​​one of the most fragile parts of a laptop, so it often suffers as a result of falls, shocks and other mechanical impacts. Black vertical stripes begin to appear on the screen, which significantly impair the usability of using the computer, and in some cases make it almost impossible. In such a situation, most often the entire repair consists of a complete replacement of the matrix. This type of repair is one of the most expensive, since the price of a new matrix is ​​almost a third of the cost of the entire laptop.

Such a malfunction can be diagnosed by several characteristic signs, namely:

• visible cracks caused by mechanical impact, blows, falls;
• dim, almost dark image;
• The screen periodically goes blank.

Except mechanical damage, the performance of the matrix can be affected by failed backlight lamps or inverter. In this case, the problem is solved by replacing the faulty components with new ones.

Performance of the video card on a laptop

Majority modern models laptops are equipped with discrete video cards with video chips soldered into the motherboard, which significantly complicates their repair. This requires special soldering equipment and certain skills in soldering BGA components.

The main reason for video chip failure is overheating. Similar problem may occur in case of untimely cleaning of the ventilation system from dust accumulated in it, as well as long work laptop on a blanket or other surface that prevents free air circulation. Most often, the repair consists of completely replacing the video chip by desoldering it. Some service centers offer Alternative option– warming up, however similar method is unreliable and does not provide a full guarantee of the continued performance of the video card.

Such a breakdown can be diagnosed using special programs, showing the main characteristics and operating parameters of the video card. The occurrence of a more serious problem is accompanied by the appearance of stripes on the laptop screen, serious distortion of the image, and in some cases its complete absence.

Where to repair a laptop screen

Repairing a laptop screen is a rather complex, time-consuming process that requires special knowledge and certain skills, so experts do not recommend trying to fix the problem on your own. Otherwise, you risk seriously aggravating an existing breakdown and adding new ones to it. It is best to entrust this matter to qualified specialists of the 24MASTER service center.

Our experienced technicians will carry out a thorough and guaranteed localization of all device problems. Modern professional equipment and tools, as well as the availability of original components, allow us to perform high-quality repairs laptop display of any complexity. Trust your equipment to real professionals.

It's a shame when the laptop was working fine, and suddenly at one not-so-great moment it started to malfunction. One of the problems is the appearance of stripes on the screen. But you shouldn’t panic right away; you need to try to figure out the cause of the malfunction.

Possible reasons for streaks on the screen

Different stripes may appear on the screen:

• Horizontal stripes in the middle of the display;
• Vertical colored lines across the entire screen;
• Ripple;
• Half of the image is missing;
• Poor image, blurry and unclear;
• White vertical stripe in the middle;
• Only a small part of the display works.

There are many more characteristic signs, now let’s look at What could be the reasons for a faulty screen:

• There are breaks in the cable, the contact periodically comes off;
• Problems with the video card;
• Fault in the motherboard;
• Dead pixels on the display.

Broken laptop monitor cable

It is not so rare for cables (video cables) of a laptop matrix to fray. There is nothing strange about this - the display mechanism is a moving part, it constantly opens and closes. In addition, the portable PC is often moved and shaken. The reason for chafing of the cable may be its incorrect installation - if the cable is connected a little crookedly. It turns out bad contact cable almost immediately after the defect appears - as soon as you turn the housing with the matrix at a different angle, the image on the screen either becomes worse or the defect disappears.

You can replace the cable yourself, but disassembly and reassembly must be done with extreme care. The replacement principle is the same on many laptops, so let’s look at a general example:

• Turn off the power and remove the battery. We wait a few minutes for the device to free itself from electrical charges;
• Open the lid and remove the plugs from the matrix frame. There are screws hidden under the plugs, unscrew them;
• Carefully remove the monitor frame;

• We unscrew all the screws securing the matrix and remove the screen. You need to keep in mind that there are screws on the side;

• The matrix cable is located on the back side of the screen. Carefully pull off the connector and disconnect the matrix from the cable;
• To get to the other end of the video cable, you will have to remove the top cover of the laptop itself. For some models, you first have to remove the keyboard;

• We disconnect the connector from the motherboard, install a new cable, and put everything back together.

Faulty matrix

If you suspect the matrix, you need to make sure it is faulty. Checking the display is very simple - you need to connect an external monitor to the laptop. Many laptop PCs have such a connector, but it can be located in different places - it all depends on specific model computer device.

If, when connecting an external monitor, the image on the screen is normal, then the reason is most likely in the matrix itself. Changing it is even easier than the cable - you won’t need to disconnect the cable from the motherboard.

Signs of a faulty matrix:

• The colors on the display are inverted - light tones become dark and vice versa;
• One half of the screen displays the picture normally, the other is all white;
• Vertical stripes appear immediately after starting the laptop.

You can also check the matrix for bending or torsion. When the monitor is turned on, we begin to gently bend or twist it with our hands. If the image changes (strips or artifacts disappear or appear), then there is a high probability that the matrix is ​​faulty and needs to be replaced. By the way, in this case the cable may also be to blame. You should pay attention at what bending of the display the picture on the screen begins to change.

Problems with the video card

There are two main problems with the video card on a laptop:

• Overheating may cause the video chip to become unsoldered (lose contact with the motherboard);
• The video card itself will burn out.

Malfunctions in the video card are characterized by the appearance of multi-colored stripes on the screen not immediately after starting the PC, but during boot operating system. If the video chip is faulty, the motherboard at its location may become very hot.

You can diagnose a video card by heating it. The chip is heated with a soldering station to a temperature of 400ºC. If after this procedure the image returns to normal, the problem is with the video card. Please note that the image will not be restored for long - you need to prepare to replace the chip.

If the video chip is unsoldered, it is still better to replace it. Soldering a video chip in workshops is not cheap, but whether it will work is still unknown. There is no point in repairing an old laptop with such a defect; it is better to buy a new laptop PC. Replacing a video card will cost around 2000-3000 thousand UAH, including the cost of the part.

Motherboard problems

The motherboard can also fail due to overheating. Often the board overheats precisely in the area where the video card is located. It should also be taken into account that often “motherboards” on “laptops” are integrated, that is, in them the video card is an almost integral component of the entire main board in the laptop. If the integrated motherboard malfunctions old laptop It’s also easier to replace the whole thing, and laptop repair itself in Kyiv will now be very expensive.

Display backlight

There is another option for a bad image - the screen is almost dark, it is almost impossible to see the picture. That is, the display works, but the backlight does not illuminate the monitor. You can check what's wrong quite easily without disassembling the computer. The button to turn the monitor backlight on and off is usually located closer to the display, on the front panel of the device next to the keyboard. If the button is not there, it is most likely stuck. Also, the button may simply break, and if it gets stuck pressed, the screen will not light up. Often the backlight switch is hidden in the hinge of the display lid's rotating mechanism. In this case, you have to partially disassemble the laptop to identify the defect.

In the worst case scenario, you will most likely need a complete
