Vertical blue stripes on a computer monitor. The reasons for the appearance of stripes on the TV screen and how to eliminate them. How to get rid of horizontal stripes

The appearance of stripes on the monitor screen is a fairly common phenomenon. Sometimes they indicate incorrect image settings, more often - a device malfunction.

Stripes on the monitor can have different colors, intensity, width and direction. The image in these areas of the screen may appear double, blurry, or completely absent. Black, white, or colored stripes may appear at the top, bottom, edges, or other parts of the monitor screen. As a rule, they appear immediately after turning on the PC, but they can also appear during operation. It is not uncommon to see flickering stripes on the monitor. Each of these cases is a consequence of significant problems in the operation of the device.

Why did streaks appear on the monitor?

Based on the number of options for the arrangement of stripes on the monitor screen, the reasons for their appearance can be completely different. Often, so-called image artifacts in the form of longitudinal and transverse stripes can be caused by video card malfunctions or motherboard. In this case, in some cases we are talking about a malfunction of the monitor itself.

Wide black stripes at the bottom and top of the monitor screen or along its edges, as a rule, appear as a result incorrect setting aspect ratio of the image.

If appears on the monitor wide vertical or horizontal stripe gray or colored tint, this may indicate damage to the matrix or the cable connecting it to the control board. Stripes can also occur as a result of mechanical stress on the matrix, for example, during careless transportation or strong pressure on the screen.

Thin vertical stripes appear on the monitor screen due to detachment of the matrix driver tracks or its direct failure.

Also, the cause of the appearance of stripes may be a damaged video signal cable connecting the monitor to the video card, or poor contact on the connectors.

What to do if stripes appear on the monitor?

You can remove stripes from the screen yourself only in certain simple cases. For example, using the settings of the monitor itself or the video card driver. But in most more complex cases, it is better to seek the help of a specialist, especially if the matrix or control board components are faulty.

Compared to personal computer, on laptops it is much more difficult to understand why a vertical stripe appeared on the monitor and how to remove it, since almost the entire structure is one piece. This is a very annoying problem. It seems like you don’t use your laptop all the time, and you handle it with care, but the problem still arises. Let's find out the reasons for its occurrence, as well as ways to combat it.

Causes of stripes on the screen

Stripes (including multi-colored ones) on laptop screens can appear for various reasons:

• Damage (poor contact, break) of the cable from the matrix to the device board.
• Failure of the matrix itself (only replacement will help here).
• Faulty video card (sometimes repair or replacement of the video card is possible).
• Faulty motherboard (often due to overheating components).

Important! On your own, you can only remove the video card driver and then install it again, although this is unlikely to help.

Finding the cause of the malfunction

Before you remove vertical stripes on your computer or laptop screen, you first need to try to determine by eye the cause of the malfunction:

1. To initially diagnose the cause of stripes on a laptop monitor screen, you will need a regular monitor that should be connected to the laptop. If the image on this monitor is excellent, without artifacts and stripes, then the problem lies in the cable or matrix. If there are also stripes on the monitor, then you will have to repair or replace the video card or motherboard.
2. Checking the matrix's response to physical impact: try with both hands, bend and twist the screen, and also try to lightly press it with your finger - of course, without fanaticism. If the stripes change, it means the cable or matrix is ​​faulty.
3. Pay attention to whether the stripes disappear or change when you open and close the laptop lid. Try both fast and slow. Changes in any direction indicate a malfunction of the matrix cable.

Important! It is worth considering that the stripes and defective pixels- these are completely different problems. Therefore, if you experience a similar phenomenon, read our separate review about colored and black spots on the monitor and ways to eliminate them.

How can you visually determine the cause of a malfunction?

Matrix mobile computer needs replacement if:

• Vertical stripes appear and disappear when the screen is torsed and bent, but on an external monitor everything is fine.
• Only one side of the screen works, while the other is completely white or with other artifacts (or a wide white stripe in any part of the matrix).
• There is a characteristic ripple on the screen.
• There are multi-colored stripes on the screen.
• When the matrix is ​​bent, the image becomes blurred.
• All colors are displayed in negative, that is, black in white, and white in black.

Important! Repair or replacement of the matrix is ​​necessary if there are many different colored lines on the screen or the image ripples, stripes and flickers, but when you move the laptop lid, the picture changes. The external monitor works without problems.

What to do with a failed cable?

So, what to do if the problem is caused by a broken cable?

1. Give it to the service center.
2. Search on the Internet or on the market for the same cable for the same matrix model, but this is unlikely due to the wide range of names.
3. Try to repair the old cable. To do this you will need a soldering iron, MGTF wire, a regular tester and electronics skills. The essence of the repair is to search for a broken cable conductor using a tester, and then replace it with a new one. The new MGTF wiring should be placed on top of the old one and soldered at both ends.

Important! You can use ordinary thin and strong copper wires - just MGTF are the most common. They can be bought in stores and radio markets.

What to do with a faulty motherboard or video card?

In case of faulty mother card or the built-in video card, the laptop will have to be repaired. This is not a cheap pleasure, so be sure to ask for agreement on the price of the repair.

If the video chip malfunctions, you may be offered three “treatment” options:

1. Warming up the chip is the cheapest option, but there is no guarantee that it will help, and besides, the malfunction may occur again later.
2. Chip reballing is a more expensive method, but if the chip is faulty, this option gives a 99% success rate.
3. A complete chip replacement is also 99% successful, but this option is much more expensive than reballing, and it’s not a fact that replacing the chip is so necessary.

Important! The motherboard could fail due to overheating, due to oxidation of the contacts, or could be slightly rusty due to, for example, spilled coffee. The repair options are the same as for the video card, plus some additional measures.

If the problem turns out to be global, and besides, your computer model is already obsolete, it makes sense to think about buying a new one. Here we offer the following reviews to help you.

The problem of stripes appearing on the screen often occurs on modern LCD TVs. As a result of what they appear, is there a connection between the cause of the breakdown and the type of stripes, how serious the consequences can be if the fault is not repaired in a timely manner - these and other questions are discussed in this article.

Types of stripes on a TV screen

A defect in the television screen in the form of stripes that appear has a negative impact not only on image quality, but also on the operation of hardware modules, due to the failure of which such problems arise. As a result, their service life is significantly reduced.

The most common types of stripes:

• thin horizontal;
• thin vertical;
• multi-colored horizontal;
• pink vertical;
• white vertical;
• blue vertical;
• green vertical;
• red vertical;
• black vertical and horizontal;
• yellow vertical;
• white horizontal.

This list does not represent all the variety of such defects on the screen. Stripes can be single or multiple, short or long, but are mainly divided into vertical, horizontal and multi-colored.

The problem may periodically appear and disappear, but under no circumstances should such a defect be left unattended - in the end it threatens an even more serious breakdown.

Reasons for the appearance of stripes

Even the most modern TVs cannot be completely immune from any premature breakdowns of hardware modules. Most often this happens due to improper care, less often due to the fault of the manufacturer.

Sometimes different stripes on a TV screen can be caused by the same damage, or, conversely, the same defects arise as a result of different reasons. To find out what reasons are the main ones for the appearance of this or that type of stripes, let’s look at them in more detail.

Narrow horizontal

Usually the cause of their occurrence is a violation of frame scanning, which occurs due to power surges in the network. As a result, this may result in chip cracks.

Here is an example of such a malfunction and a method for fixing it:

Multi-colored horizontal

When horizontal stripes of different shades, as well as streaks or ripples appear on the TV screen, there is a high probability that the contact cable has become disconnected from the matrix. In this case, it should be re-soldered.

Often the problem is caused by a broken motherboard. This usually happens when the performance of the image control unit deteriorates.

Black vertical and horizontal

Such stripes are often located on different sides of the screen, sometimes in its center. This is one of the most problematic breakdowns, requiring serious costs, since the cause in most cases is damage to the decoder. In this case, a complete replacement of the matrix will be required.

If urgent measures are not taken, the lines will expand and the screen will stop lighting. We will have to invest even more money to restore its functionality.

Thin vertical

The reason for the appearance of vertical stripes on the TV screen that do not light up at all may be a breakdown of the decoder or matrix columns. This occurs, for example, as a result of a lightning strike or sudden power surges. If timely measures are not taken, the stripe will expand and eventually completely cover the screen.

Vertical pink

Most often, color stripes on the screen appear as a result of damage to the monitor matrix. Failure may occur due to a failure of the power supply system, impact or other similar influences.

The reason may also be normal wear and tear of the elements: if a vertical stripe of pink color (less often purple) appears on the monitor, the reason for this is most often a breakdown of the scaler. Sometimes such a defect is present even in new TVs, but here the cause, as a rule, is a manufacturing defect - in this case, the TV should be immediately returned to the store under warranty.

Vertical white

It can be barely noticeable and flickering or, conversely, clearly defined. The appearance of such stripes - as well as stripes of any other shades - primarily indicates a problem with the matrix.

You can check the correctness of this assumption in the following way: press, move (without much effort) or otherwise gently influence this element. If the line disappears and reappears on the screen, the part is damaged and needs to be replaced.

Another example of a breakdown with vertical white stripes, and the method for solving it is discussed in the video below:

Vertical blue

Most often, such stripes occur when the video card is overheated or worn out. If the warranty period has not expired, the best option the item will be replaced.

Another reason for the appearance of vertical blue (cyan) stripes may be a broken matrix cable contact.

Another reason is that as a result of overheating, the solder balls of the video processor peeled off from the BGA substrate.

Vertical green

Most often, the cause of its occurrence is damage to the cable that connects the image-forming board and the LCD matrix of the TV. The width of the strip can be quite large and amount to several centimeters, or, on the contrary, it can be very narrow - one pixel. It often appears unexpectedly on the screen, and after the TV has warmed up sufficiently, it disappears and the picture is displayed without interference. In some cases, the strip remains, but looks lighter than the main background.

Vertical red

Its appearance most often lies in a broken contact of the matrix cable. Sometimes the cause is burnt elements. This may also indicate that the cable connectors are damaged or dusty. Such stripes can also appear due to the fact that a track on the board has peeled off or the VGA wire has been damaged.

Yellow vertical

When it appears on the LCD monitor, the first thing you need to do is try to connect it to the network by disconnecting it from system unit. If the bar disappears, then the problem is most likely in the video card. The capacitors may be swollen and will need to be replaced. Otherwise, the problem must be looked for in the display.

The video below discusses several examples of TV matrix malfunctions and describes the reasons for their occurrence, and provides contacts for complex repairs:

Troubleshooting methods

The appearance of stripes on a television screen is not a reason to immediately begin global disassembly of the device. Before looking for the cause of faulty circuits and boards, you must first check:

• connection of the cable that displays the image - is the connector dirty?
• settings on the TV itself using the automatic settings Images.

If stripes remain on the screen after manipulations, it is worth considering serious repairs. As we found out earlier, the reasons for the appearance of different bands are mainly due to a malfunction:

• matrix loop contact;
• the matrix itself;
• elements of boards and microcircuits.

These problems can be fixed, but sometimes buying a new TV is a better option than rebuilding it. Some spare parts are very expensive, and besides, there is no guarantee that if parts and circuits are changed, the TV will work correctly.

Let's sort it out possible ways eliminating these and other faults.

Cleaning the matrix cable contact

Problems with contacts can arise due to improper use of the device or poor quality assembly and care, for example, cleaning the screen.

To determine poor contact, sometimes a simple inspection without using a magnifying glass is sufficient. It is not difficult to fix the problem with oxidized contacts, especially if the damage area is small. You will need a regular blade or knife to remove plaque. After removing the plaque, be sure to check the voltage using a multimeter.

An example of home cleaning of LCD TV cable contacts is shown in the video below:

Poor contact can also be caused by incorrect connection of the cables. In this case, you need to disconnect all the cables and then connect them correctly.

Eliminating a broken matrix cable

First, you should verify the accuracy of the alleged breakdown by moving or pressing the cable. If the stripes disappear, then the damage has been identified correctly.

Then you need to arm yourself with a soldering microscope and find damaged wiring. The work requires endurance and precision, as well as skill and necessary equipment. Defective areas are restored with conductive varnish. You can also heat the contacts to an acceptable temperature, but in no case should you allow overheating, otherwise, instead of repair, you may end up with additional problems.

This procedure is complex, and often masters do not undertake it.

Replacing the cable

If it is discovered that the cable has failed, you will have to replace it with a new one, and always one that is suitable for this TV model.

The design feature of various brands of TVs is that each manufacturer has its own, individual design, so before you begin repairs, read the instructions.

The cable is located in the TV case, so you will have to unscrew the fasteners connecting back. If they are difficult to give in, do not try to unscrew them clockwise: as a rule, all the bolts unscrew against it. You need to be extremely careful when disassembling, since the cable in most cases is located on the cover itself - this will prevent damage and breakage of the elements.

There is no need to solder the wires - the connecting elements have connectors. To remove the cable, you need to press on a special latch. A broken cable, of course, can be replaced without a workshop, it’s not difficult.

How to remove cables of various designs for their subsequent replacement is shown in the video below:

If you intend to independently replace components or the matrix itself, you must consider the following:

• Most conductors have a fairly small diameter, so you need to work with them very carefully to avoid damage;
• to restore parts you need not only experience in this matter, but also stock up on good equipment: a microscope, infrared soldering station, a set of tools for minor work with circuit boards, etc.

Replacing the flexible film cable of the matrix- the procedure is complicated. Usually the technicians suggest replacing the entire matrix so as not to bother with soldering the cable. Before embarking on such a serious repair, it is advisable to learn from mock-ups or unusable TVs. Still, it is recommended to carry out such repairs at a service center. Unfortunately, it can cost almost two-thirds of the cost of the TV, so you must first find out the price of the service, and only then make a final decision.

Stripes of various colors and sizes, ripples, streaks and other similar defects can appear on the TV screen not only due to minor damage, but also due to serious damage. They can’t always be fixed on your own: sometimes you need to contact a service center, pay for expensive repairs, and replace parts.

The appearance of stripes on a laptop screen falls into the category of complex breakdowns. And if you hope that you will deal with this problem within a few minutes, then unfortunately, this is not the case.

Difficulty of diagnosis

Diagnosing such a problem on a laptop is much more difficult than on a regular computer. This is due, first of all, to the design features of laptops and their more complex structure.

Stripes on a laptop screen can be horizontal, vertical, black, white or colored, and the reasons for their appearance usually lie in problems with the latter’s hardware devices.

You can also see ripples on the screen, skewed images, mirror color rendition (black - gray, red - green, etc.), displaying the image as a negative.

Reasons for stripes appearing on a laptop screen

Let's look at the reasons for this phenomenon:

• 1. The simplest reason in this situation is overheating of the video card.

For example, such a situation was with Dell laptop M5110. In the lower part, in the area of ​​the discrete video card (there are two of them), it got so hot that the leatherette on which it stood began to melt and stick to it.

As a result, the periodic appearance of colored stripes and ripples on the screen. The problem was partially solved by purchasing a stand with laptop coolers. Stripes appear, but very rarely.

• 2. Complete failure of the video card.

As a rule, the main reason for such a breakdown is also overheating or hardware failure. The power supply copes well with surges in the power supply, so this reason is unlikely.

In such a situation, either stripes appear on the screen even when the OS is loading, or the laptop does not start at all.

This problem can be solved by repairing or upgrading the video card. This is not easy to do on a laptop; you need to have the skills of at least a novice electronics engineer. But we will talk about these points further.

• 3. The system board has failed.

The situation is the same as point 2; diagnosing the problem is difficult, but possible. We will talk about this further.

• 4. The cable has failed.

From motherboard a special cable goes to the matrix, through which the signal is transmitted.

Poor contact at the connection point, burnout or fracture of the cable can cause interruptions in signal transmission to the matrix, hence the appearance of stripes.

• 5. Problems with the matrix, its failure.

The situation is critical, there is only one way out, the matrix requires replacement.

In this situation, it is a rare case when reinstalling or updating the video card drivers helps, and hoping that this will help is not worth it, it is indeed a rare case.

Diagnosing problems

The most important task in all this is to correctly diagnose the cause of the problem.

A complete diagnosis of the reasons for the appearance of stripes on a laptop screen can only be carried out in service centers on special equipment.

But initial diagnosis, which can also tell us a lot, is also possible at home.

Using an additional monitor

An additional monitor can be connected to a laptop via a connector VGA.

There can be two results:

1. Everything will be displayed normally on the additional monitor;
2. Similar bars will appear as on the laptop screen.

The result of step 1 tells us that the laptop’s video card is working, problems should be looked for in the matrix and cable of the laptop.

Result 2 tells us that there are problems with system board and video card. In both cases, repairs are inevitable.

Checking the matrix

• Checking the matrix at home is possible by partially deforming it.
• Try not to push the monitor screen too much in areas where there are the largest number of stripes.
• Then, carefully, with both hands, try to slightly bend the screen in a horizontal plane.
• In both cases, notice how the colors of the stripes change, their contrast and brightness.
• If changes are visible, then the cause of the breakdown is in the matrix or cable.

When do you need to change the laptop matrix?

We replace the laptop matrix in cases:

• Provided that a parallel connected monitor is working. If, when the matrix is ​​deformed in the horizontal and vertical planes and its surface is pressed inward, the color rendition of the stripes changes, the stripes disappear and reappear.
• The presence of stripes is observed at all stages of computer boot - BIOS, WINDOWS.
• Ripples appeared on the screen, wide white or multi-colored stripes were visible.

• The matrix displays the image in negative or the colors are being substituted, for example, it should be red, but green is displayed, blue is yellow, black is light gray, etc.

Checking the cable

• The cable is flexible and this is understandable, because the laptop screen cannot be in the “stowed” position all the time, and this is not a computer. Deformation of the cable occurs constantly, and therefore the probability of its failure is high.
• Slowly opening and quickly closing the lid and vice versa, observe how the strips “behave.” Any changes on the monitor screen indicate that the source of the problem is the cable.

What does the matrix cable look like for Asus laptop X51RL.

When do you need to “deal” with a loop?

Condition – a parallel connected monitor shows a clear picture.

• It is necessary to repair, or better yet change, the matrix cable in cases where the image on the screen is unclear, ripples, flickers periodically, or has a large number of colored and white lines.
• While the laptop is booting and running, there are vertical columns of white pixels on the screen.
• Opening and closing the lid “revitalizes” all these errors on the screen.

Video card

The video card requires attention if the laptop screen and a parallel connected monitor display a picture with multi-colored lines, and other errors in the image are also duplicated.

• At the very beginning of the computer boot there are no horizontal, vertical, black, white or colored stripes, but at the stage Windows boot stripes appear.
• When Windows boots, the image disappears and a black screen appears.
• The laptop gets very hot in the area where the video card is located (the motherboard may also get hot).

Motherboard

• The motherboard requires attention in the same cases as the video card (see above).
• If replacing the cable, video card and matrix did not correct the situation.
• Now let's look at ways to solve the problem with stripes on a laptop screen.

Ways to solve the problem

Plume

Problems with the cable going to the matrix most often arise in older laptop models. In new models, manufacturers are already using more advanced design solutions, thanks to which the cables last a very long time.

This is the difficulty of repair, finding such a cable to old model laptop will be difficult, but possible.

Before you go to the radio market or electronics flea market, write down the model of the matrix, without this there is no way.

The service center is unlikely to want to sell you such a rare “spare part”, and no one will want to lose a client, but what if you decide to give the laptop to them for repair.

If you find the cable you need, you’re lucky; if not, you can try to do it yourself.

To do this, you will need some minor electronics skills, a soldering iron, solder, rosin, a tester and, most importantly, MGTF type wire.

To ring a loop with a tester, you will have to reach both ends. The repair technology is simple as hell.

We call, find a break (if there is one), and instead of the broken wire, solder a duplicate wire parallel to it.

If there is no break, then the problem lies in more expensive components.

Motherboard

The system board may not fail completely. As a result of overheating of its individual section, the microchip or bus responsible for exchanging data with the video card may fail.

Also pay attention to the PCMCIA slot where the video card is inserted, to see if there are any burnt or oxidized contacts there. After all, they pour tea and coffee onto laptops.

But in any case, repairs cannot be avoided. But first order diagnostics, and if you are offered to re-solder any chip or clean the contacts, you can still agree to this.

Complicated repairs to a burnt-out motherboard are not worth it; it’s easier to replace it with a new one.

Video card

The situation is similar with a video card. A video chip is soldered onto it, which can fail as a result of overheating.

Here you need to follow three paths. Let's consider them in descending order, with respect to the high cost and reliability of the work.

1. Replace this chip immediately (expensive, but reliable);
2. Dismantle and reinstall the same chip - Rebowling (in most cases it gives results);
3. Warming up the chip (pay less, but in 99% of cases the problem will recur after a while).

Everyone decides for themselves which method to use.

Do not forget, before leaving your laptop for service, to agree with the technician on the prices for all types of work performed, or better yet, agree on their contract.

Also, do not forget about the certificate of work performed, which indicates the date of repair, what was changed or what was repaired, as well as the warranty.

Bottom line

Of course, it is impossible to describe all situations when stripes appear on a laptop screen.

The problem is so specific and individual that it requires separate study in each case.

It all depends on the laptop model, matrix type, design features and analysis of how often such problems appear on this particular model.

But if we take in percentage terms what was most often repaired and changed in this situation, then cases with matrix replacement are about 40%, cable replacement or repair is about 20%, video cards are about 20%, motherboards are approximately 20% (with taking into account the failure of the integrated video card).

As we see, in most cases it is necessary to change the matrix, but this is not a cheap undertaking; if the cost of replacing it exceeds 50% of the price of a new laptop, then there is no point in such repairs, it is easier to buy a new one.

But everyone decides for themselves. We wish that your laptop screens always delight you with clear and bright images. Good luck.

The problem is easily solved. The asking price is 50 rubles or tens of times more. But I advise the “masters” to give money LAST.

Let's talk about stripes on the monitor screen; what to do if vertical or horizontal lines suddenly appear on it? Some individuals advise immediately running to the “masters”. They say the problem is complex, and any intervention will only make it worse. At the same time the price similar service about 1000 rub. But why pay!? Let's solve the problem ourselves!

To start the reason should be determined streaks appearing on the computer screen.

Alas, but a chance software error MI-NI-MA-LEN. It's a matter of hardware. So check:

A) Are hdmi and other cables connected well? Are they damaged?

I recommend unscrewing everything and blowing it out (even when you are sure that everything is in order). Also make sure that there are no serious deformations on the blue cable (which leads to the monitor). They could very well be the culprit behind the irritating stripes.

B) The video card is damaged due to overheating.

Naturally, you won’t see this visually. There are practically no swellings or other visual signs of damage on it. Indirectly, this can be indicated by a dust-clogged cooling system and Aida temperature readings.

There are two things you can do here:

1. Remove the video card, clean its contacts (especially the part with which it is inserted into the motherboard). It’s extremely rare, but it helps, I’m serious: the chances are slim.

2. check it on another, 100% working computer.

But there may be problems with either of them, the third reason is:

B) Motherboard malfunction.

Stripes on the monitor screen may be due to this. Whether the voltage jumped, whether there was overheating or a manufacturing defect is not so important. The fact is that this happens everywhere. In addition, if upon inspection (there is no need to remove it from the system unit) swelling of the condensers (such barrels) or their “blackening” are visible, then with 90% chance you have found the reason for your misfortune.

A faulty matrix is ​​the cause of streaks on the screen.

This is sadness. You can't fix it yourself. Unless to carry out diagnostics - connect the monitor to a laptop or other PC. The stripes remain - take the monitor to the service center. I’ll also tell you one “interesting” method.

At your own risk: lightly press (as if you were gently massaging the body) on the monitor that is turned on, preferably in the area of ​​the stripes. Now watch out: if the location of the stripes changes, the reason is in the monitor matrix or HDMI cable.

Stripes on the laptop screen.

Do the lines/ripples change their location when the laptop is opened or closed? Move it back and forth with at different speeds. Are you seeing the above? The matrix cable is faulty.
