1. User errors
2. Technical difficulites
3. 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.

Consequences of resetting settings

In most cases, when the above symptoms occur, only rebooting the LG SMART TV can help. In this case, this term refers to two actions:

• disconnecting equipment from the power supply for a short time;
• Reset settings to factory level.

In the first case, no fatal consequences will occur when rebooting, minor errors will simply be eliminated, running but not closed applications and programs that occupy operating memory and slow down the process will be reset, and the communication session with the Network will be restarted, which is important if the web browser is not working correctly.

In the second case, all changes and settings made by the user will be reset and the factory settings will be restored. But along with the client installations, all software errors (not hardware errors) will also disappear. This process is considered a last resort, since after it you will have to perform the following steps again:

• log in to the system;
• search, configure and sort TV channels;
• activate pre-installed applications;
• download and install additional software (from the official store or via a flash drive) and so on.

Important! If resetting all settings to the factory level does not help solve the problem of incorrect operation of the LG SMART TV receiver, then the failure is of a hardware nature, and only service workshop specialists can fix it.

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.

Why doesn't the TV start?

An LG TV receiver may not show “signs of life” for many reasons, so there is no point in starting a chaotic check. It is necessary to sort out the possible breakdowns and then carry out an inspection. There can be three types of faults:

1. Incorrect settings. The LG device does not turn on because... is blocked by settings that are activated by the user and are not related to the problem.
2. System failure. Problem with software or third party applications.
3. Peripheral problems. They arise as a result of incorrect operation of one of the devices connected to the TV.
4. Hardware failures. Failure of the TV receiver itself.

A black screen after a network startup does not mean that the LG TV does not turn on.
This is the order in which you should inspect the TV, because... simpler problems occur more often and are easier to fix.

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:

1. 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).
2. 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.

Possible problems and their solutions

In most cases, if the LG SMART TV model provides the ability to reset user settings and factory settings, then there are no problems with this process. In some situations, users complain about difficulties encountered when restoring their installations. For example, the TV had 30 TV channels, and after a reboot and a new search procedure it became 13. In this case, the reason is not a return to factory settings, but problems with the tuner/receiver - it needs to be reflashed or taken to a service workshop.

Advice! LG Electronics technical support specialists recommend resetting the settings to factory values ​​every time after updating the firmware of a SMART TV receiver.

Summarize. If the frame just freezes when playing video content on your LG SMART TV, you don’t have to immediately start resetting the settings to factory values. Perhaps there is simply not enough driver, and to correct the situation it will be enough to add codecs. And if you regularly experience slowdowns when starting video/audio, incorrect response to pressing the remote control buttons and other manifestations of failures in the system, then in this case you first need to reboot the equipment by disconnecting from the power supply, and only if there are no results, return to the factory settings.

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.

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:

1. First you need to discharge the capacitors. To do this, turn off the TV completely and unplug it from the outlet.
2. Remove the back cover and check the functionality of the fuses, cables and cables.
3. 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.
4. 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.

Diagnostics

The problems listed above are too numerous to consider all of them. Therefore, you should “cut off” a number of problems and take on the most likely options. They will be able to identify specific signs on TV.

One of them is the “behavior” of the indicator lamp when turned on. By default, it lights up brightly. If this is so, then you can be relatively calm, because... There is no serious damage to the TV.

A network indicator light will be an excellent “helper” in troubleshooting. But you may encounter other cases, namely:

1. The light flickers randomly, and at different frequencies. There is a malfunction in the power supplied to it, and therefore to other electronic components.
2. The indicator does not turn on. Check the electrical network and socket. If everything is in order, then you should think about repairing the TV at a service center.

But in order to accurately verify the specific list of possible problems, you should check the indicator lamp itself. To do this, you need to remove the housing cover and inspect it, as well as the board, for possible damage. If a lamp or a separate contact has come loose, the problem can be solved by ordinary soldering.

Advice! It is better to have auxiliary equipment and additional wires on hand. With them you can find a fault much faster by elimination. For example, a spare unit will allow you to quickly understand that it is the main one that is broken.

In addition, it is better to immediately arm yourself with a multimeter and a soldering iron in case you find problems with the hardware of your LG Smart TV or peripheral equipment.

The indicator and the contacts going to it will also have to be checked for serviceability

Then recheck the indicator’s response again.

Only after making sure that it is working can you judge the reason why the LG TV does not turn on.

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.

Voltage drop

If the LV is completely extinguished, this does not always mean that the equipment is broken. Often the TV does not turn on if there are problems with the electrical network at home or the common antenna.

This happens due to:

• cable damage;
• socket failure;
• problems with the electrical network.

Then you should act according to the scheme.

1. Plug the TV into a different electrical outlet and boot it up immediately.
2. If you cannot turn on the equipment, then check whether another electrical appliance works from this outlet.
3. When there are no problems with the operation of another device, but the television does not turn on, contact a TV technician.

Another reason that an old model LV does not turn on may be a blown fuse.

When the light is on in the usual color (red, green, blue), then the TV may not be communicating with the TV signal source. In this case, you need to start the monitor’s standby mode and try to open any media file from a smartphone or flash drive connected via USB or HDMI on the large display. This way you can make sure whether Smart-TV is working or not.

The backlight is broken

A black screen on an LG TV may appear due to a broken LED backlight. When the LEDs fail, the video image ceases to be displayed on the display - the polymer liquid crystal layer ceases to be illuminated.

Solving the problem on your own is difficult, but possible: here are detailed instructions. This requires special equipment and parts. To accurately correct problems with LED backlighting, you need to take the TV to a certified service center.

By clicking on the “Order a call back” button, you confirm that you are of age and agree to the processing of personal data in accordance with the terms.

Most often, the TV does not turn on due to power problems. The old power connector may burn out or become damaged, then we will replace it with a new one. Or there may be a problem with the power supply. If it is repairable, we will be able to restore its operation, or replace it with a new one.

The power indicator is no longer lit

It happens that the device cannot turn on at all, the light does not light, the TV does not respond to the remote control and the buttons located on the front panel of the device. It is likely that the electricity has disappeared.

Important! It may happen that the indicator burns out, but then the TV should still turn on.

Based on the facts that the light does not light and the TV does not turn on, we conclude that there is a problem with the electricity supply.

Power failure occurs in several situations:

• there is no electricity anywhere in the house;
• the machine gun in the dashboard was knocked out;
• the socket where the cord plug from the television device is plugged in is broken;
• the extension cord is damaged if the TV device is connected to the outlet through it;
• There were problems with the electrical wiring.

The first thing to do first is to check if the outlet and extension cord are working properly. It is also necessary to look at the shield and change the position of the toggle switches.

If the previous action did not help, you should then look for the cause of the problem in a broken socket. To do this, it is recommended to simply plug the plug from the TV into another outlet.

When it doesn’t work, there is no electricity. To fix a wiring problem, you will need to call an electrician.

When the model of the TV device is a picture tube, the cause of its breakdown is a blown fuse. A blown fuse can be replaced with a new one.

Most often, the reason for the inability to turn on a TV device is a breakdown of the TV device of more modern models (for example, a breakdown of the microcircuit, power adapter or capacitor).

All equipment as a whole should be diagnosed. Once you have identified a part that is not working correctly, you should simply replace it. After replacing the broken part, the TV device should, in theory, turn on.

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.

LG TV does not turn on, the indicator is blinking

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.

If your LG TV does not turn on, contact the LG service center in Moscow, and we will definitely help! Leave a request on the website or call!

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.

Technical problems

Time negatively affects circuit boards, transistors, capacitors, fuses and other spare parts of a TV device. To determine the cause of the malfunction, the device should be disassembled.

Important! When you suspect a technical problem with your TV, it is recommended to contact an LG service center.

The matrix and backlight are burnt out

If the TV has problems with the LCD matrix or LED backlight, this is noticeable by the fact that there is a sharp deterioration in image quality and darkening.

The main signs of backlight and matrix failure are:

• absence of picture, but presence of sound;
• the appearance of black and white or color stripes on the monitor;
• beating pixels, ripples;
• The LG logo does not appear when the device is turned on.

Important! When you shine a flashlight on the screen, you can see the image on it, you don’t need to look for other problems - it’s a burnt-out backlight.

You can check the backlight if the TV is practically disassembled into parts.

In this situation you will need:

• ability to check parameters of circuit sections;
• know the basic operating voltage values ​​of semiconductor crystals;
• demonstrate accuracy, dexterity and soldering skills with an air dryer.

If you lack the necessary knowledge and skills, it is better not to start repairs yourself.

In a situation where the backlight of the LG TV does not work, the cost of repair will be significant; it is recommended to contact the seller of the device and request a warranty repair.

Failure to comply with operating conditions

Failure to follow operating instructions often leads to equipment malfunctions. Before you connect your TV and start using it, it is important to read its operating instructions.

The most common TV breakdown caused by the user is mechanical damage to the screen, which requires replacing the matrix and backlight.

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.

What to do

If the TV randomly stops working after starting, to determine the type of failure you must:

• check the functionality of the remote control;
• make sure that the power cable and plug are intact, have no signs of damage, and that the plug itself is tightly inserted into the socket;
• go to settings and make sure the sleep timer is disabled;
• disable automatic updating of the TV receiver and remove all applications that can independently launch the device;
• disassemble the TV and diagnose the power supply.

Having discovered a malfunction during the inspection of the television panel, the user needs to fix it on his own, if possible, or seek help from specialists.

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.

The indicator lights up steadily

Most problems with an LG TV that prevent it from turning on are not related to the power supply. If the power light comes on, the screen itself is immediately checked - perhaps it’s just not showing.

You can verify this by calling any menu:

1. If calling the menu from the remote control and buttons on the case did not bring any results, then you can skip this section and move on to the next one;
2. When the screen responds and the settings are displayed, the problem arises with the display itself.

In the second case, three options are possible:

1. The antenna or its amplifier is faulty.
2. The antenna jack or AV input is damaged.
3. The TV channel settings are lost.

Advice! Finding a fault faster is as easy as shelling pears - use signal reception from another source. For example, display an image from a computer and see the results.

If it shows, there is a problem with the antenna, otherwise the problem may be with the firmware.

After successfully calling the menu, you can say that the LG Smart TV is working, but does not show

You need to perform a repeat auto-search for TV channels.

If this does not help, then the antenna with the socket is inspected. It is possible that it was blown around by a strong wind or that the amplifier failed. You can read more about this in the topic “TV does not show”.

If the TV just recently worked, but stopped turning on.

You need to pay attention to proactive screen blocking by settings or a third-party utility:

1. Custom modes. These are “Energy Saving”, “Sleep” and other modes that can block operation or completely turn off the TV receiver immediately after startup. To do this, you need to check the settings on the TV and exit this mode. Afterwards you will need to deactivate the timer, otherwise it will start working again.
2. Child protection. The mode differs from those described above in that it blocks the buttons on the TV body. And if the remote control is faulty, you won’t be able to get out of it right away. This will require a network restart. Afterwards it is deactivated in the same user settings.
3. Third party utilities. Not all LG TV receivers support multifunctional operating modes and additional widgets are installed to obtain them. They will also need to be checked.

Advice! If this does not help, do not rush to update the software. Perhaps the failure is caused by a third-party utility, or a specific timer was not found simply due to lack of familiarity with the equipment. In this situation, resetting the current settings helps a lot.

All timers must be deactivated and disabled in the settings

After making changes to the settings, it is recommended to perform a network restart of the equipment, and then enter the settings again and check that the changes are saved.

Firmware

An LG TV often does not turn on because the executive files (drivers) responsible for image output are damaged or the software is outdated. Searching for specific libraries and utilities is too routine; it is much better to completely reflash the TV.

But first you need to clarify what exactly happened to the software:

1. If there is no information in the system settings, you can use an existing drive with a bootable firmware file;
2. When there is a notification that the current version of the software is out of date, then an update over the network will be required.

Video instructions: how to restore the current software version or update the firmware of an LG TV.
In the second case, you will no longer be able to use the installation file, because it contains an outdated firmware version. You can learn more about this in the topic “How to flash a TV.” After installing the new software, the equipment will restart itself and turn on.

If your TV receiver freezes, contact a professional!

If the TV freezes, you have to restart it and change the settings. Self-intervention will help only in the simplest cases. In all other cases, it is better to call a qualified technician.
