- User errors
- Technical difficulites
- How to fix it?
When an LG TV does not turn on, its owners immediately prepare themselves for expensive repairs and associated expenses. The reasons why the indicator flashes before turning on and the red light is on or there is no signal at all can be different - from user errors to technical failures. What to do, how to troubleshoot if the TV does not want to turn on - these issues are worth understanding in more detail.
User errors
The breakdown of complex electronic equipment is always expensive - the cost of repairing plasma or LCD screens often turns out to be completely unprofitable for the owner. When your LG TV doesn't turn on, don't immediately suspect the worst. Most likely, the causes of the problems are elementary errors or accidents that can be fairly easily eliminated.
To eliminate most user errors, a detailed study of the manual supplied with the TV is usually sufficient: many typical problems are listed there.
Technical difficulites
Among the technical malfunctions due to which the TV does not respond to the power-on command, the most common failures of the fuses are detected. They are designed to protect expensive equipment from voltage surges and, for obvious reasons, can burn out. If this happens, the TV turns off, does not respond to commands from the remote control and buttons for a long time, you need to contact the service center specialists for a more accurate diagnosis.
The reasons why LG TV equipment does not turn on may lie in other technical faults.
- Power supply failure. It is located inside the case, and if it fails, it can give symptoms such as a long loading time of the screen, extraneous sounds (clicks, whistles), intermittent indicator signal - it blinks, the contact is inconsistent. Failure may be due to overheating, overload, or burnout of the power supply. And also after a strong voltage drop or thunderstorm, a protective blocking against a short circuit may be triggered.
- Software glitch. If an error is discovered in the firmware or the user himself violates the correct algorithm, the TV goes into eternal reboot mode and does not respond to other commands. This sometimes happens when updating the TV system to WebOS. If this happens, you need to download the correct version to an external data storage source and install the update from it manually.
- There is a malfunction in the backlight or matrix. At the same time, the logo does not appear on the screen when loading, there are stripes or illuminated areas on the dark panel, and cracks have appeared on the glass. Sometimes there is sound, but the image is not broadcast.
- The remote control doesn't work. In this case, the indicator on the case blinks as usual, the buttons on the TV itself turn on and switch functions. Commands do not work from the remote control.
- Unstable voltage. In this case, the indicator lights up red and flashes intermittently (in normal mode, this occurs before the image on the screen turns on). The TV's power system signals a low current in the network; it is not enough to display a picture.
When I turn on my LG TV, no image appears on the display. Instead of a television picture there is a black screen. In this case, the sound is transmitted without any defects. In 90% of cases, the cause of a black screen on an LG TV is a problem with the device’s hardware. It is difficult to identify the problem on your own, and impossible for people who do not understand technology and boards. Therefore, the best solution would be to contact the nearest service center.
In any case, you need to know the main reasons that can become a problem in transmitting images to the LG TV screen.
If your LG TV does not turn on at all, we recommend that you first study our instructions.
Types of problems
If there is no picture on the LG TV, but there is sound, then this is just one of the signs of equipment malfunction. There are other symptoms that also indicate problems with the operation of the TV device. Let's look at the most common defects.
Symptom of malfunction | Features of troubleshooting |
The image is constantly blinking and the brightness level has decreased. | Deactivate the TV's energy-saving mode. |
There are defects on the screen, but the diagnostic test did not find any problems. | Check the connection according to the signal source. |
Incorrect picture brightness. | Go to Advanced Settings to adjust brightness settings. |
The image appears double or is too blurry. | Activate the Auto Motion Plus option. |
The TV turns off randomly. | Disable Eco mode and energy saving features. |
Low picture quality, distortion. | Check the quality of your TV signal reception. |
Incorrect color rendering. | Disconnect the cable and then connect it again. |
Distorted color rendering. | Reset the TV to default settings. |
A dotted line appeared along the TV screen. | Change the aspect ratio to 16:9. |
The user can eliminate the defects listed above independently. Many of the troubleshooting methods described above can also help if there is no picture but there is sound.
Checking the LG TV cable
The first step is to check the cable that is responsible for transmitting the video signal (HDMI, antenna, television), and the cable of the Internet provider that provides digital television services.
There are two ways to check the cable:
- Search for damaged contacts. To do this, you need to remove the sheath - the insulating material made of PVC or HDPE, under which the wires are located. Next, you should diagnose the contacts and the plug (the connector that is inserted into the TV).
- Using additional software. You can install Monitor Asset Manager (MonInfo) on your computer. The utility detects problems associated with the transmission of video signals to TV screens and monitors. If the program detects a cable malfunction, you need to manually check the cable - most likely there are damaged contacts.
Matrix problems
Most often, the main cause of all display problems on LG TVs is a matrix failure. The matrix may fail due to a short circuit or mechanical damage: the TV falling onto a hard surface or moisture getting inside the device.
A faulty matrix cannot be repaired. The only solution to the problem is to replace this component with a new one. You can do this yourself (this requires professional skills in repairing household appliances) or in a technical service.
Capacitors burned out
Capacitors on the TV can burn out - they are used to accumulate charge and energy of the electric field. This problem is especially common in models with a liquid crystal display. One of the reasons for the breakdown of these components is sudden voltage changes.
To determine whether the capacitors are faulty, you need to remove the back cover of the TV. All the main components that are responsible for the operation of the TV are on the board. If the capacitors are swollen - slightly increased in size - this means that urgent replacement of parts is required. Sometimes swollen capacitors explode, which can cause damage to other components on the board.
Inverter problems
The inverter on an LG TV may burn out. It is responsible for supplying voltage to the backlight lamps, adjusting the image level and brightness, protecting microcircuits and boards from overloads and short circuits.
If the inverter is faulty, the display will stop displaying light. This means that instead of a video image, the TV will display a regular black screen.
To determine if the inverter is broken, you need to conduct a visual inspection of the main components of the TV, which are located on the circuit board under the back cover. To check this component you will need a multimeter - a special device for measuring various electrical quantities.
The inverter can burn out transformers, lamps or controllers located on the lamps. The burnt part must be replaced with a new one. In some cases, you can repair the inverter - you will need a soldering iron for this.
Reasons for the disappearance of the image
The most common reason that the image on a TV set disappears is hardware failure. What to do in such situations? How to restore correct broadcast of digital or analog TV? It is necessary to carry out diagnostics to determine the failed module.
Immediately after identifying a damaged component, it must be replaced. You can do this yourself. However, this option is relevant provided that you have the necessary skills and equipment. If you do not know how to repair a TV, then contact a service center.
Now let's move on directly to considering the main reasons for the disappearance of the image.
Power supply burnt out
If there is sound, but the picture constantly jerks, the screen is dark, the brightness has dropped, or other defects have appeared, it means that the power supply of the LCD TV is not functioning correctly.
Users who do not know how LG LED TVs work should under no circumstances attempt to repair them themselves. Call a specialist who can quickly determine the reason for the incorrect operation of the TV.
However, diagnostics can still be carried out independently at home:
- Start by discharging the capacitors. Unplug the TV. Unscrew the fixing bolts and then remove the back cover. Check the cables and cables; some of them may be damaged. Be sure to test the functionality of the buttons and fuses.
- Inspect the power supply for melted or charred resistors and capacitors. If there are such elements, they must be replaced immediately.
- Measure the voltage of the power adapter output circuits. The obtained indicators must correspond to the parameters indicated on the board or in the technical documents.
- Voltage fluctuations. For example, the voltage level reaches 200V, find the cause of the breakdown in the primary power circuit.
- If you tapped the TV case and the image returned to normal for a few seconds, it means that the cause of the problem was poor-quality soldering of the power supply elements.
Resoldering of contacts and other elements must be carried out with professional equipment. Using improvised means may aggravate the original problem.
Broken cable
If the quality of the audio signal does not raise any questions, but there is no image, you must definitely check the integrity of the connecting elements. We are talking about a cable. Which one exactly? The answer to this question depends directly on the signal source. Therefore you need to inspect:
- antenna cable;
- HDMI wire;
- cord connected by cable TV provider;
- Ethernet cable (provided that Smart TV is used).
To determine the cause of the black screen, use special software. For example, the Moninfo utility. It allows you to identify problems associated with the transmission of audio and video signals. If the program detects failures, you must carefully inspect the cable for damage.
Matrix failure
Matrix failure is perhaps the most common reason that there is no picture on the TV screen. Damage to the matrix can also cause a number of other symptoms:
- video shakes;
- the image is displayed only on half the screen;
- Various stripes appear around the entire perimeter of the screen.
Why doesn't the matrix work? The component fails due to short circuits and mechanical damage. It is impossible to repair a faulty matrix. Therefore, the part is replaced. If defects begin to appear for no reason, for example, the image suddenly darkens. The matrix elements are probably damaged; replacing them costs much less than the entire module.
Is it possible to change the matrix yourself at home? Theoretically this is possible. However, it will be extremely difficult for a person who has never repaired televisions to do this. In addition, instead of the broken part, you need to install the original matrix. Buying branded components is very difficult.
Capacitors burned out
In LCD TVs, problems with capacitors appear due to voltage surges. Signs of capacitor failure:
- the picture is double;
- no image;
- the TV turns off randomly;
- low brightness level;
- incorrect color rendering.
In order for the device to start working correctly again, you need to disassemble it. On the board you will see a damaged capacitor and a blown fuse.
If the breakdown is not corrected in a timely manner, the problem will worsen. After a while, problems will occur in the operation of the power supply. The set of procedures aimed at diagnosis is identical to the situation with a matrix failure.
Replacing capacitors is a complex type of TV hardware repair. The slightest inaccuracy will cause the problem to worsen. Therefore, it is wiser to entrust the troubleshooting to the service center specialists.
Matrix cable
Sometimes the image on an LG TV disappears due to damage to the matrix cable. Failure manifests itself in the form of the following symptoms:
- The image periodically disappears;
- unsatisfactory picture quality - interference and ripples appeared;
- horizontal or vertical black and white and colored stripes appeared.
The specifics of troubleshooting will directly depend on the specifics of the cable damage. If the fault was detected at an early stage, then the service center technicians will resolder the damaged sections of the cable, restoring the operation of the TV. In some situations it is necessary to change the matrix cable completely.
The second option is considered a more durable solution to the problem. A soldered cable will not last long. Therefore, it is wiser to immediately replace it with an original component. You shouldn't do this on your own. Entrust the work to professionals.
Burnt out inverter
Due to the fact that the inverter is broken, the TV screen stops working. Symptoms of failure:
- distortions appear, the picture twitches;
- the image is completely missing or takes a long time to load;
- After turning on, the TV display dims and goes out immediately;
- sound transmission is carried out correctly, but ripples have appeared on the screen;
- The picture is very blurry, low brightness level.
The main function of the inverter is to supply voltage to the backlight lamps. Therefore, if the TV screen does not light up, then perhaps the reason is a malfunction of the inverter.
The module performs many other functions:
- conversion of direct (12-volt) voltage into alternating voltage;
- stabilization of the lamp input current to the required values;
- adjusting the image brightness level;
- matching the output stage with the input tube impedance;
- protection of microcircuits and boards from possible short circuits and overloads.
How to determine that the problem with the absence of an image is caused by a breakdown of the inverter? It is necessary to disassemble the TV and carry out a comprehensive diagnosis. Module failure can be determined during a visual inspection.
To restore a TV, you need to have at your disposal a hot-air and infrared soldering station, as well as a multimeter. A good knowledge of physics and electronics will also be required. It is extremely difficult to say which element has failed. Incorrect operation of the TV may be caused by a breakdown of the lamp, transformer, or board controller.
Non-working backlight
If the LG TV does not broadcast an image, then the reason may also be a breakdown of the screen backlight. Modern models are equipped with LED backlighting, which provides the highest quality picture. It is extremely easy to determine a breakdown; if the picture blinks or ripples appear, then the cause of the problem is incorrect illumination of the polymer LCD layer.
How to fix this problem? It is almost impossible to do this with improvised means at home. If only because you won’t have the necessary parts. You need to order components from official distributors. They will have to wait a very long time. And in general, this is a very expensive pleasure.
Therefore, the best way out of this situation is to contact a service center. Certified workshops work with official suppliers. Therefore, they can quickly change the entire backlight or a faulty LED.
Power supply failure
Another reason why an LG TV has a black screen instead of a picture, but there is sound, is a broken power supply.
To carry out self-diagnosis, you need to perform the following steps:
- First you need to discharge the capacitors. To do this, turn off the TV completely and unplug it from the outlet.
- Remove the back cover and check the functionality of the fuses, cables and cables.
- Now conduct a visual inspection of the power supply: if there are charred or melted resistors and capacitors on it, then these components need to be replaced urgently.
- Measure the voltage of the output circuit of the power supply - all measurements must match those indicated in the technical documentation of the LG TV.
It is better to entrust the replacement of parts to professionals - employees of service centers or repairmen of household appliances. Improperly replacing resistors or capacitors can lead to new damage or short circuits, which will require you to buy a new TV.
Account registration
The procedure will be as follows:
- open the main menu of the LG TV by pressing the “Home” button on the remote control;
- Click “Login” in the upper right corner of the screen;
- select “Registration”. If an account in the LG system was created previously, you should select “Login” and follow the steps specified in the last paragraph;
- agree to the user agreement and privacy policy;
- indicate your email and click “Authentication”, and then create and confirm a password, and optionally agree to receive messages by email;
- Click the “Registration” button. You will then be prompted to use the TV's built-in browser to confirm registration, but it is recommended that you select "No" at this point. It will be better and faster to continue the procedure on a computer, smartphone or tablet: open an email from LG Smart World from the selected device and click “Complete registration”;
- On the TV remote control, press “Exit”, then open the main menu on the TV again, click “Login;
- indicate in the window that opens the e-mail and password used during registration, check the box next to the “Remain logged in” item, select “No” on the notification about entering additional information and click the “OK” button.
The registration process is completed, which will now allow you to fully use your LG TV.
The matrix cable is damaged
The image on an LG TV may disappear due to damage to the matrix cable - a set of contacts and wires that connect the board that forms the image and the display.
To check the functionality of the loop, you need to perform a visual inspection of the wires. Damaged areas can be re-soldered, this will help restore the screen operation. At the same time, there is a high probability of repeated breakdown of the matrix cable.
Therefore, the best solution to the problem is to replace this component with a new one. When choosing a matrix cable, you need to pay attention to the TV model - the part must be original and compatible with the TV brand.
Internet slows down on LG Smart TV
If your LG Smart TV slows down, then for the Internet to work correctly you need to follow simple steps:
- connect the router;
- open “Menu”;
- select the connection “Via Wi-Fi”;
- enter your login and password.
The device will connect instantly. If something is done incorrectly, the message “Cannot get network settings” will be displayed. Then it is best to update the firmware for the router.
Problems may occur with the network cable. The solution to this problem depends on the provider. Call a specialist to your home or get advice by phone. The Internet will not appear if you simply connect the cable.

LG TV does not turn on: causes and solutions
LG is a popular manufacturer of household appliances. The brand produces reliable, high-quality and functional TVs. But, unfortunately, even the best quality equipment breaks down over time.
It often happens that the LG TV does not turn on. Why is this happening? Problems can be associated with a large number of problems, which we will talk about later.
Why doesn't my LG TV turn on?
For plasma, LED and LCD LGI TV models, the malfunction may manifest itself as follows:
- The TV does not turn on, but the indicator light is on.
- The TV does not start, but the light blinks red.
- When you turn on the TV, extraneous sounds occur: whistling, humming, clicking.
- The TV does not turn on and the indicator does not light up.
- The TV does not start, freezes on the screen saver (the LG logo lights up and nothing happens)
There are many reasons why the TV does not turn on. They can be divided into three main categories. These are system failures due to malfunctions of software or applications, peripheral problems that arise due to improper operation of devices connected to the TV, as well as hardware failures associated with failed TV elements.
Typically, troubleshooting starts with external devices connected to the TV. Settings and cable damage are also examined. Only after this do they begin to diagnose the internal elements: matrix, board, etc. It is better if specialists do the testing.
The TV does not turn on, the indicator does not light up
If the TV does not turn on and the indicator does not light, first of all, check whether there is voltage in the outlet, whether the power cable is damaged, whether the remote control or power button works. If everything is in order, the problem needs to be looked for inside the television receiver. Hardware failures in this case are usually always associated with a lack of power. This means that contacts and cables could have come off the power board. The contacts could also be closed.
Checking the TV boards is done with a multimeter. All contacts are checked, starting from the network input, until a place is found where there is no current supply. If such an area is not detected, it means that the power supply, socket or cable is most likely broken. The power supply is usually replaced. The contacts are soldered, just like the cables.
The TV does not turn on, the indicator is on
If the TV does not turn on, but the indicator is on, the problem is definitely not in the power supply. In this case, everything is in order with the connection to the electrical network. First you need to check whether the operating mode of the TV receiver is selected correctly. The backlight, LED strip or inverter could also burn out, or the firmware could crash.
To determine the cause of the breakdown, the screen is first checked. If settings are displayed when you press the menu button, there is a problem with the image broadcast. In the second case, three options are possible. This is a breakdown of the antenna or amplifier, damage to the antenna socket, or a settings failure.
Wrong mode selected
If the TV was working normally just recently, but suddenly stopped turning on, it may have exited standby mode. The following could turn on by accident:
- Custom modes “Energy saving”, “Sleep”, due to which the equipment turns off immediately after startup. You need to deactivate the timer and exit the incorrectly set mode.
- Child protection. In this case, the buttons on the TV receiver body will be blocked. If the remote control does not work, you will have to use a network restart.
It's also worth checking out third-party utilities. You can reset the current settings to factory defaults. Of course, if you do not know how to perform the above steps, it is better to immediately contact a specialist.
Backlight problems
Often a black TV screen indicates problems with the backlight. If the LED strip or backlight lamp fails, there is no picture on the screen. The backlight is usually changed, and this is done only at a service center. It is impossible to cope with such a task on your own without special skills.
Problems with firmware and software
If the LG Smart TV does not turn on, but the indicator is on, it may have lost the drivers that are responsible for broadcasting the image. The software may also be outdated. In this case, you can find special utilities - but this takes a long time and is therefore impractical. It's easier to do a flashing right away. But first, the cause of the software failure is clarified. To do this, check the information in the system settings. If it is not there, a flashing is definitely required. If there is a warning that the software is out of date, you will need to update it. Software is usually downloaded from the Internet.
After installing the new software, the equipment restarts itself, and then turns on and starts working in normal mode.

If the TV does not turn on, but the indicator blinks with a certain frequency or chaotically, the monitor mode may be turned on, there are problems with the receiver or antenna due to which there is no signal, or hardware failure.
Monitor mode enabled
If the indicator blinks, but the TV refuses to work, check whether it is being used as a monitor. You can solve this problem in no time - first wake up the computer from sleep mode by pressing any button on the keyboard or moving the mouse, and then set the correct settings.
Problems with no signal
If the TV does not turn on due to lack of signal, this can be easily checked. Set up a signal from your PC and see if the image will be broadcast on the screen. If yes, then the problem is with the receiver, antenna or antenna jack. Only a master can fix the damage.
Hardware faults
The presence of hardware faults is indicated by chaotic blinking of the indicator. Most likely, the problems are related to the operation of the TV's electrical circuit. Therefore you need to do the following:
- Disconnect peripheral equipment and TV from the power source. Peripheral equipment includes set-top boxes, players, antennas and other devices.
- Disconnect peripheral equipment from the TV.
- Connect only a TV with a single power supply.
Next, you can try to connect the antenna and receiver one by one - this will help you find the broken device. If the peripheral equipment works correctly, the problem is hidden in the TV itself.
A breakdown can be determined by the blinking of the indicator. The light can flash a certain number of times - this is a special code that conventionally indicates the type of malfunction. To decrypt the signal, read the instructions. If necessary, contact specialists.
The TV does not turn on and clicks, crackles, hums
If, when starting the TV, extraneous sounds occur in the form of clicks, crackling sounds, etc., but the TV itself does not turn on, the following could happen:
- Overheating of components.
- The TV's power supply is overloaded.
- Power supply failure.
Another reason is a blown fuse. This is the most common problem with LG TVs.
A safety lock could also be triggered, which often happens during a thunderstorm. The TV turns off and won't turn on again. This type of breakdown is mainly due to power surges. The safety lock is activated to prevent damage to the microcircuits, and the relay produces clicks. You won't be able to repair the TV yourself. The solution to the problem is the help of specialists.
Problems with the TV matrix
Problems with the matrix can be identified even without special knowledge. The picture quality will become much worse, and blackouts will appear on the screen. The main signs indicating matrix failure include the following:
- No picture, but there is sound.
- Colored, black and white stripes on the display.
- Ripples and dead pixels in the image.
- No LG logo when turned on.
Repairing or replacing the matrix is an expensive undertaking, comparable to buying a new TV (see price comparison photo above). Therefore, it is better to buy another TV than to repair a broken one. But you need to contact specialists in any case. They will diagnose the device and determine whether the problem is in the matrix or whether other elements are broken, for example, a cable, which is much easier and cheaper to repair.
Why isn't my LG TV working yet?
The TV may not turn on for other reasons: not only those listed above. These include:
- Heating near the video adapter. If the device was operating “at the limit” and overheated, the fuse could trip. Because of this, the TV receiver will not turn on for some time. We need to wait a little. The malfunction occurs mainly when they try to play movies or programs in Ultra-HD or 4K formats on a TV with a low resolution.
- Broken motherboard. This is a serious breakdown that requires a professional approach. The fact that the board has failed can be indicated by a burning smell from the TV case. The only way to fix damage is to replace it.
- Capacitor failure. The capacitor may crack or swell due to the high resistance of the contact material. It is replaced with a new one. You also need to establish why the resistance level has risen - due to voltage surges or due to moisture getting on the board.
Conclusion
Regardless of the reason for the malfunction of the LG TV, it is unlikely that you will be able to fix the problem yourself. The only thing a user without special skills and knowledge can do is turn off the incorrectly set mode or change the outlet if that is the cause of the malfunction. In all other cases, it will not be possible to do without the help of a specialist. Remember that unqualified repairs can completely damage the equipment, and this will lead to much more significant expenses. Therefore, immediately contact a specialist if you encounter problems with the operation of the TV. Don't make things worse.

Classic TVs are used less often now, but modern models have characteristic disadvantages - there may be “brakes”, the TV may freeze completely, and it may take a long time to respond to commands. There are many reasons, in most cases only a professional can find a solution.
LG TV turns itself off and on
If you don't have any issues with flickering, but find that your LG screen turns off on its own, there may be a few issues going on. Check and see if any of these factors are causing your TV to turn off frequently.
Reason: TV is not connected correctly
Before checking anything else, make sure the TV's plug is properly inserted into the outlet. You'd be surprised how often an outlet has trouble holding the plug, especially if you have kids and pets running around.
Solution
This might be the easiest fix on the list! Look behind the TV and see if the plug is securely inserted into the wall. If not, insert it back.
If you find that your TV's plug keeps falling out of the socket, consider purchasing a new one.
Reason: timer settings
Some TVs come with pre-installed features that users don't necessarily need, but are easy to disable. Many LG users report similar problems, especially immediately after purchasing the TV.
These settings will cause your TV to turn off at different times for different reasons:
- Shutdown time turns off the TV at a specified time.
- On Time, on the other hand, will turn off your TV after a set number of hours of inactivity without pressing any buttons.
- Finally, the sleep timer will turn off the TV after a set period of time, regardless of whether you press any buttons or not.
Solution
To check the timer settings on your TV:
- Press the smart button.
- Tap Settings , TIME , then WHEEL or Enter .
- Make sure your TV's Turn Off Time , On Time or Sleep Timer settings are turned on .
- Change your preferences.
If none of these settings are enabled and your TV still turns off randomly, don't despair. You may encounter another problem.
Reason: high threading load
Many people use their TVs exclusively for streaming services like Netflix, Hulu, and Disney+. Nowadays, with more people working from home than ever, people find themselves turning on the TV as background noise.
Due to such a large streaming load, some TVs experience cache or memory overload, which can lead to periodic rebooting of the TV. This can be very annoying and unfortunately the problem does not resolve itself. If you want to continue using your TV for streaming, you can reduce the problem by resetting the settings.
Solution
As with many similar electrical problems, you will find that turning it off and on again is a quick fix. Disabling your device completely will clear up any number of internal errors and help clear the cache that may be causing screen problems.
Reset your TV by turning it off, unplugging it, and waiting at least 30 seconds. The longer you wait, the better. Then plug it back in and use it as usual. This should make the problem less serious, at least for a while.
TV freezes on screensaver
One of the most common problems: the device turns on, there is power, but the final download of the software does not occur. In some cases, you can try to fix the problem yourself. Use the control panel buttons to get to the menu and perform a reset. Next, the TV turns off, all wires are disconnected for an hour.
If the problem remains after this, you will have to contact a specialist. Usually the first action of the wizard is to update the firmware. If this does not help, the only option left is to restore or replace the motherboard. There is no need to carry out repairs yourself; incompetent intervention can lead to serious failures and errors.

Common situations with TV receivers freezing
There are many reasons why the TV screen freezes - from software glitches to hardware defects. In addition to the static startup screen, other situations are possible:
- Freezes when turned on (the device does not respond to commands from the remote control or control panel). The method is standard - turning off the power for a period of 30 minutes to 1 hour, relieving the voltage on the coils, and reflashing. If all else fails, diagnostics are needed.
- When watching a video. There may be problems with the built-in browser or full memory. In most cases, updating the software resolves the problem. Another reason could be an unsupported video file format.
- The digital channel freezes. Often the problem occurs even in the absence of a CAM module, which decodes the video sequence and matches it with the signal system of a particular TV, and is installed on devices with a built-in digital tuner. The short-term solution is to turn it on and off. It is possible that the external signal has weakened. Only a specialist can name the exact reason after inspecting the equipment.
- Online cinema IVI or YouTube freezes. After launch, the broadcast “fades”, this is caused by low data transfer speeds and a weak Wi-Fi signal. A quick way to solve the problem: reduce the video quality in the settings.
- The image on the TV freezes after a short period of operation. The TV works for a while and the picture freezes, but often the sound does not disappear, and less often it loops. If basic measures do not produce results, you will need the help of experienced engineers.
- Problems not related to Smart TV. Insufficient Internet speed, many third-party widgets in memory, full cache of the integrated web browser, need to update the software.
Separately, it is worth paying attention to freezes on regular TV without Smart functionality. In the vast majority of cases, they are caused by external factors - technical failures of the signal source, problems with a digital set-top box.
