Constant use, long periods of continuous viewing, improper maintenance of technicians - all can cause streaks to appear on the TV screen. Even the most modern models are not immune to this malfunction. Moreover, the stripes themselves can have a different character: appear temporarily, be horizontal, vertical, white, black, colored. In each case the reasons are different. After diagnosis, some breakdowns can be repaired yourself. But if the matrix fails or another complex breakdown occurs, it is better to contact the specialists so that you do not have to buy new household appliances.

Additional Tips

Horizontal stripes, the width of which does not exceed 1 centimeter, can not only appear on their own, but also disappear - in this case, the TV owner needs to observe the condition of the display for 2-3 days.

If screen defects do not disappear or appear again and again, the cause of the breakdown is hidden in a faulty matrix, the repair of which is best entrusted to a qualified specialist. If the user observes multi-colored stripes of different widths, then the malfunction is probably related to the matrix cable, which has moved away from the T-con board.

It is recommended to turn off the power, disconnect the back panel from the TV body and slightly move the connecting element. Then serve food.

If after such an operation the horizontal stripes do not disappear, you will have to call a teleworker who will conduct additional diagnostics of the device and advise how to remove artifacts.

Conclusion

Now we know why colored or white stripes appear on the screens of TVs from Samsung, LG and other manufacturers. Do not forget that attempts to fix the problem yourself can only make the situation worse if the owner of the device is not qualified in the field of electronics repair.

Common Causes of Streaks

The ability to watch TV programs is achieved by broadcasting an encrypted signal, decoding it by hardware and displaying the picture using a matrix. Common reasons why horizontal stripes appear on a TV while watching movies are:

• Dirt gets into the video signal cables. Very small debris, dust, and moisture may get in.
• Incorrect image settings, broken default settings.

You can fix these errors on your own. But the reasons for the appearance of a large number of vertical stripes can be much more serious:

• The matrix has failed;
• The matrix cable is broken and oxidized;
• Malfunctions in software modules.

Advice. You shouldn’t figure out the faults of expensive modern Smart TVs on your own. Maximum – you can check the image settings. It is better to entrust the elimination of other breakdowns to the specialists.

Let's take a closer look at what stripes of color, type and quantity indicate what errors in the operation of televisions.

Causes of malfunction

When broadcast to a modern screen, the image passes through three channels. An encrypted signal arrives, the hardware decrypts it, and then the video is displayed on a monitor or TV. If a horizontal line appears on your TV screen, first check the most likely causes:

• Contamination in video signal cables: small debris, dust, moisture.

• Error in image settings (resolved by restoring default settings).

If numerous vertical or horizontal stripes appear on the screen, the image “freezes” in one frame, changes in proportions, periodically goes completely dark, the defect appears on all channels and with any settings, it is necessary to inspect the device for global damage:

• Matrix malfunction. A narrow horizontal strip that does not emit light expands over a few days and occupies 1–10% of the screen.

• Incomplete contact on the matrix cable. If the contacts are oxidized or broken, the cable is replaced with a new one.

• Breakdowns of software components and individual working elements.

One vertical line on the monitor is not a cause for concern: spare parts for popular models can be inexpensively ordered online. It is more difficult for owners of large LCD TVs and Smart TV devices.

A single strip indicating the failure of a couple of spare parts can cost half the cost of a new TV. Two or three emergencies, and repair costs will exceed the market value of a new screen.

IMPORTANT! Have streaks appeared on the TV screen even though two weeks have not passed since the date of purchase? Contact your dealer for a replacement. After the exchange, the counter is reset: you again have 14 days to fully check the device.

Don't forget to check the warranty period of the screen: it depends on the manufacturer and can be up to 2 years for some models. Under warranty, repairs are free, but only until you (or a third-party service) try to fix it yourself. The addresses of the nearest service centers can be found on the manufacturer’s website.

Possible types of stripes and breakdowns

Horizontal and vertical stripes on the TV screen occur due to software glitches, internal and external breakdowns. It is worth paying attention to the color and the number of defects in order to understand what the error may be.

Thin horizontal stripe

It is worth paying attention to the frame scan, which gets lost after sudden voltage surges, for example, during a thunderstorm or power outage. As a result of the same problems, microcracks may appear on microcircuits.

Multi-colored horizontal

Such stripes can fill either part of the screen or the entire monitor. They have different shades and resemble ripples. Such a malfunction often indicates a failure of the matrix cable. In this case, it needs to be re-soldered, but you should entrust this process to a professional. He will immediately determine whether there are any faults in the matrix or image control unit.

Dark, black horizontal and vertical stripes

They can be located in the center or throughout the monitor. Such stripes on the TV screen often indicate serious and costly breakdowns. These include damage to the decoder, without which it is impossible to reproduce the signal. Most often it requires a complete replacement.

Advice. If black horizontal stripes appear on the TV screen, you should not delay repairs, even if at first they do not interfere with viewing much. The more violations, the more expensive the repairs will be.

Small vertical defects

Depending on the type of TV, such breakdowns indicate failure of the decoder or matrix column. The reasons are power surges. If even one stripe is not eliminated in time, it will spread until it covers the entire screen.

Pink vertical strokes

The monitor matrix gives similar failures. They can appear not only from power surges in the network, but also from mechanical damage to the TV.

Normal wear and tear can also cause pink vertical streaks to appear on your TV screen. A purple defect is also preparing about him.

Important! Don't look for reasons why your new TV is broken. The appearance of stripes on the screen is a manufacturing defect that must be corrected under warranty. To do this, just contact the store where you purchased the equipment or a service center from the manufacturer.

Vertical white line

The strip can be small, barely noticeable, or, conversely, thick and pronounced. The reason is the matrix failure or problems in its operation. Checking whether this TV element is really damaged is quite simple:

• Gently press your finger onto the white line;
• See if she has disappeared or not;
• If it disappeared and then reappeared, there is a breakdown in the matrix.

But do not press too hard, otherwise you can damage the equipment even more.

Blue vertical lines

After overheating or prolonged use, blue vertical stripes may appear on the TV screen. They indicate problems with the video card, which has its own expiration date. Another reason is the peeling of the matrix cable or the peeling of the solder ball of the video processor of the BGA substrate.

Advice. Even if the cause is identified, you should not disassemble the TV yourself unless you are a master. The elements of the matrix and microcircuits are so small and fragile that it is not difficult to damage them.

Green vertical defects

Such breakdowns indicate damage to the cable connecting the image forming board and the LCD matrix. Such a line can be anything: from a wide line of several centimeters to a narrow line of 1-3 pixels.

Interesting fact. If the strip appears suddenly after the TV has been running for a long time, turn off the equipment and let it cool. Often, along with overheating, the defect also goes away.

Red or yellow vertical stripe

Failure of the matrix daisy chain connection often produces red stripes. They also indicate that the cable connectors are damaged or dusty. It is not uncommon for a track on the board to peel off or the VGA cable to become damaged. Some of these defects can be repaired at home.

Vertical yellow lines are a sign of problems with the video card. And also after moisture gets on the TV, as a result of which the contacts swell and oxidize.

Important! Despite the availability of a large number of instructions on how to independently solder cables or repair microcircuits, you should not do this without special education. The exception is that you already want to buy new equipment, but left this one for personal experiments.

What does the appearance of stripes on the screen indicate?

When using a TV, many users encounter stripes appearing on the screen. These lines could be:

• colored;
• black or white;
• pass horizontally;
• place vertically;
• be visible all the time or periodically disappear from view;
• occupy a certain area of ​​the screen;
• block the entire display of the device.

If a line appears on the user’s TV that corresponds to one of the types of lines listed, then this is a clear sign that the TV is broken. Such a variety of types of possible stripes on a TV screen arose due to the fact that the appearance of certain lines on a TV depends on the breakdown of specific parts of the device.

What problems can be fixed at home?

White or colored stripes do not appear on the TV screen due to a poor signal from the operator. Therefore, you should not call the line and ask about serviceability. But from dirt getting into the connector for connecting the antenna or cable - quite well. These microparticles do not completely block the signal, but only spoil it.

Before cleaning the connector, you can check whether it is the correct one. To do this, plug the flash drive into the TV or connect the screen to the computer via another wire. If the malfunctions go away, you can clean or replace the connector. For this:

• Carefully inspect the connector on the TV. Make sure there are no mechanical creases or damaged contacts. Take a soft brush and wipe off any dust.
• Look at the wire connector. Also visually check for damage and clean with a soft brush.
• Be sure to review the entire cable. Avoid kinks, removed protective braiding, or furniture on the wire.

Important! If you need to replace a connector or wire from a digital television operator, you need to call a specialist. They know exactly which cable was used. And the cost of such repairs is low.

Problems with TV settings

Not fair, but image settings can affect the appearance of stripes. To eliminate this error, you need to take the TV remote control. Go to settings. Set the default parameters. The exact instructions depend on the brand and series of TV. You can read the instructions and find the factory parameters on the official websites of the manufacturer.

Important! Do not confuse ripples and stripes on the screen. When the picture blinks, the image jumps - it's ripples. Constant even stripes with different thicknesses mean possible failures in the settings, failure of the internal components of the TV.

Breakdowns requiring repair in service centers

If the stripes on the TV screen are not associated with wires and settings, the reason is a breakdown of the internal elements. Only a specialist can carry out an accurate diagnosis. It takes into account the type of matrix, carries out diagnostics, and corrects errors.

There is no need to carry out repairs yourself for a number of reasons:

• Even when disassembling the TV, you can damage various components. Especially in thin models, where all the elements are located very close to each other.
• If you manage to get to the matrix, when dismantling it, it is easy to damage the cable, increasing the cost of repairs.
• The matrix must be soldered under a microscope using a special set of tools. There are no such things in a regular “home workshop”.

Important! Do not under any circumstances attempt to disassemble the TV while it is under warranty. Even if you unscrew two screws before contacting the service center, your case may be considered out of warranty due to attempts at self-repair.

Other display failures

Do not confuse stripes that appeared due to internal violations, failures and mechanical damage. If the monitor is broken as a result of an object hitting it or falling, there will be not only stripes, but also spots, separate light and dark areas.

Dust getting under the protective panel causes dark, white areas to appear. And these are also not stripes, which most often indicate a breakdown of the matrix and the elements connecting to it.

In any situation, it is worth calling a specialist for diagnostics. And if the amount of repairs seems too large, there is always the option of buying new TVs at an affordable price and simply replacing home appliances.

Recommendations for caring for equipment to prevent streaks from appearing on the screen

To prevent a vertical stripe or horizontal colored stripes from appearing on a plasma or LCD TV, you should properly care for the equipment. To extend the service life, follow these tips:

1. Do not wash equipment with water or a wet cloth. Any ingress of moisture causes a short circuit, as well as burnout and oxidation of internal elements. As a result, not only streaks may appear, but the TV may also completely fail.
2. Constant, daily movement of the TV causes internal damage. Microcracks appear and cables may become disconnected. Therefore, it is important that the device is fixed in one place and not subject to constant movement.
3. Do not allow dust to accumulate on the display or the back panel of the TV. Microparticles gradually penetrate inside and stick to the contacts. As a result, the components overheat, the contacts become deformed and stripes appear on the screen. The best option for getting rid of dust is to blow it with a vacuum cleaner, but taking all precautions.

Important! Any cleaning, moving, or fixing of the TV can only be done when it is turned off. And not just turned off by a button, but pulled out of the network. After wiping and treating to remove dust, you should not immediately turn on the equipment. You need to wait 2-5 minutes.

How to avoid stripes on a SAMSUNG TV

In 90% of cases, you can avoid the appearance of vertical and horizontal stripes on your SAMSUNG TV. To do this, you need to follow the following recommendations:

• Do not allow dust to accumulate inside the TV case. Dirt settles on the board where the contacts, wires and chips are located. Because of this, problems arise with displaying the picture on the TV display. A universal way to clean a TV from dust is to blow it with a vacuum cleaner.
• Do not spray the LCD TV display with water or wipe the screen with a wet cloth. This can cause moisture to get into the base of the case, and then onto the contacts of the board or matrix cable. To clean the display from accumulated dust, use special products designed to care for LCD screens. It is better to wipe the body with a dry cloth or napkin.

General recommendations

What to do if stripes appear on your TV? Do not panic, but carry out diagnostics.

1. Carefully examine the strips themselves. Determine their color, quantity, location.
2. Try to let the TV cool down. Disconnect it from the network. Leave for 30-60 minutes. Ventilate the room. Turn it on and check if the problems go away.
3. Inspect the cable through which the signal is supplied to the TV. Clean the connectors with a soft brush and make sure they are inserted correctly.
4. Go to the TV settings. Set the image parameters to factory settings.

And if all else fails, it’s best to call a technician or take the equipment to a service center. So, the repair will be faster and cheaper than trying to solder the matrix yourself or replace the cable.
