Spontaneous reboot of the TV: causes and repairs at home

Owners of television receivers with SMART options have the broadest capabilities comparable to a computer - they can watch not only television, but also films, TV series, and other video content online, download games, surf the Internet, communicate in popular social messengers and so on. All this functionality is provided by a set of special programs called the operating system. As a result of external circumstances or internal system errors, “smart” equipment sometimes malfunctions, which manifests itself as freezes, slowdowns, refusal to play any multimedia content, and other signs of incorrect operation. In this case, restarting the device will help. How to reboot an LG Smart TV will be discussed in our material.

How does the error manifest itself?

Sequencing

On LG TVs, it is recommended to clear the cache not only to be able to launch services, but also to reduce the load on RAM. After deleting temporary files and unused applications, your device will run much faster.

If you delete the files of absolutely all installed programs when clearing the cache, you may need to log in to your LG account again.

You will have to wait until the memory clearing is complete. Normal playback will return, the receiver's memory will be freed of unnecessary files. As a result, the error will disappear.

If the problem is not solved, try rebooting the LG Smart TV, that is, resetting its settings. To do this, press the Home button on the remote control and go to settings. Select the General tab and Factory Reset.

You cannot turn off the TV during a reboot!

How to avoid memory overflow?

There are measures you can take to help prevent this difficulty without cleanup. One of the ways to use the TV’s functionality is to install additional software that will solve the problem of memory overload and allow you to watch and listen to any content without interruptions.

Using web portals where files are saved in blocks also helps avoid cache overflow.

Another way is to update Web OS. Perhaps in later versions such glitches will be eliminated, since the software for the TV is constantly being improved by equipment manufacturing plants.

Content:

The question of how to clear the cache on an LG TV usually arises if there is a problem with insufficient memory to run media content. “Smart” TVs allow you not only to watch regular and cable TV channels, but also to access the Internet to listen to audio recordings, watch videos on YouTube and obtain other information. However, when trying to launch the browser, a notification about insufficient memory constantly appears on the screen. To remove it, you need to clear the browser cache on your TV.

Why does a smart TV run out of memory?

The main reason for frequent cache overflow is the limited functionality of browsers that are installed on smart TVs. To play any information, the program first downloads it to the internal memory, only after that it will be possible to watch a movie or start an audio recording. The cache is cleared automatically periodically, but the device may not do it quickly enough. As a result, the video recording may, for example, download up to half, after which the viewing will be interrupted, and a message will appear on the screen indicating that there is not enough free space in the browser cache. In this case, you have to clean it manually and then continue watching. When cleaning, you need to take into account some features of the functioning of the TV memory:

• If there is not enough memory, the application may be closed several times; after each new launch, the information begins to be downloaded again.
• An error will not appear on the screen if the information is loading slowly and the cache has time to clear automatically.
• The internal memory of the browser cannot be increased by installing any external media, be it a hard drive or a flash drive.
• There is no need to clear the cache if you use the TV only to watch TV programs and not to access the Internet.
• Memory problems are not related to the content of the content; they can occur when viewing any Internet pages and media files.

How to clear the browser cache of an LG TV or another model? To solve the problem as effectively as possible, you can install a newer version of the software - it may provide a larger amount of built-in memory. Another option is to return the settings to the factory settings.

Causes of a memory full error

The problem is that when you next want to use the built-in browser, an error occurs: it is impossible to watch videos or listen to music online due to insufficient memory.

TV browsers have limited capabilities, so when you watch, for example, a video, it is initially loaded into the device’s memory, and only then can it be played. Then the memory is cleared, but, unfortunately, it does not always have time to free up the required amount, which causes the problem of its overflow. As long as it is not refilled, everything will function as it should; therefore, the movie can play up to half, and only then an error will appear.

Sometimes it may be preceded by the message on the screen “ the application will be restarted to free up memory ”, then the application or site crashes and reloads again, this can repeat several times in a row.

That is, the basis of the disadvantage is the unforeseenly small amount of initially built-in memory.

Clear cache on LG TVs

You can also clear the internal memory not of applications, but of the browser itself. To do this you need to follow these steps:

1. Using the “Smart” button on the remote control, switch the TV to the main smart mode menu.
2. Launch the browser, go to settings mode by clicking on the button located in the right corner.
3. Select "Clear cache" from the menu to remove all saved files from it.

After cleaning, it is recommended to restart the TV. As a result, all temporary files will be completely deleted, and the problem with playing any files will disappear. The operation will have to be repeated periodically if you often use the smart functions of the TV. A more reliable way is to timely update your browser and other software. This is an opportunity to increase the amount of memory, therefore, the problem with cache overflow will occur much less often.

Clear cache on Samsung TV

Owners of Samsung TVs with smart functionality may experience similar problems. If you have a question about how to clear the cache on a Samsung TV, you should look for a way not just to free up the internal memory one-time, but to find the reasons for its frequent overflow. There are several ways to free up the necessary space for applications to run correctly:

• Removing unnecessary programs and all kinds of widgets. The starter version often contains many applications that are not used by the user, but at the same time intensively take up memory. They are periodically updated by downloading additional information, which also takes up a lot of space.
• Reset settings to factory values. As a result, all saved data is reset, which makes it possible to free up space for recording new information.
• Solving problems with your Internet provider. In some cases, traffic is artificially limited due to the selected tariff, while the TV perceives this as a lack of its own memory. You can choose a more suitable tariff in accordance with the mode of use of Smart TV.
• Update installed programs using only new firmware from official sources. A common cause of failures is incorrect versions of programs that overload memory.
• SMART HUB reset, that is, complete memory clearing.

How to clear cache in Samsung TV browser? To do this, press the SMART button on the control panel, and then the reset button. Select “Reset” in the menu that opens and wait until the operation is completed, after which it is recommended to restart the TV. After clearing the cache and resetting the settings, all saved user information is deleted.

You will need to re-enter your passwords and log into your personal pages on social networks. However, this will allow you to remove all accumulated unnecessary information and ensure correct video playback via the Internet. Some Samsung TV models do not work correctly with content with Russian-language names. In this case, the system may also display an error indicating problems with the browser's memory. To fix the error, install a special widget that helps the program recognize the name and start the movie or audio recording.

External reasons

These include faults that you can fix yourself without disassembling the TV.

Timer enabled

Most users set a timer and successfully forget about it.

Checking its status is quite easy; the TV will turn on or off only at a certain time. For example, at 18.00 or 23.00.

You can find out whether the timer is currently enabled as follows:

1. Open Settings.
2. Go to the "Time" item.
3. Turn off the timer if necessary.

Wi-Fi adapter and antenna

You can look for the cause of the problem in the router or antenna. To do this, you also need to go to the settings and check for possible failures.

For example, “Sleep mode” is currently activated. This means that the TV will turn on automatically when connected to a Wi-Fi network. It is also worth checking for signal transmission failures.

Faulty monitor

If the screen malfunctions, the device can also turn off on its own. There may have been a short circuit in the wiring or an inverter failure in the past that caused the image to go black or the monitor to turn off.

In this case, there is not much you can do other than buy a new display.

I recommend reading: The TV screen does not show

Remote control

The operation of the keys can also affect the condition of your TV. If they stick or fall out, the TV will turn on or off by itself.

To check this you need to:

1. Activate the camera on your mobile phone.
2. Point it at the top end of the remote control.
3. If the light starts blinking without pressing any buttons, it means that the TV is turning off due to a malfunction of the keys on the remote control.

Checking the Bluetooth remote control is also quite simple; for this you need:

1. Remove the batteries from the remote control.
2. Next, turn on the TV by pressing the button on the TV panel.
3. If the startup went smoothly, without interruptions, then the reason for turning off the TV should also be looked for in the remote control. You can eliminate sticky keys by “stretching” the key in a circular motion.

If this does not help, the remote control will have to be disassembled and the buttons replaced. If it is impossible to carry out a replacement, for example, this model is no longer produced, it is recommended to buy a universal TV control device.

Adverse operating conditions

The TV turning off on its own may be caused by improper operation of the device. Pay attention to where the equipment is located.

If placed in a room where there are high temperatures, high concentrations of dust and humidity all year round, the TV panel will break very quickly.

Therefore, if the TV turns off on its own, try moving it to another room, and do not forget about regular maintenance of the device.

Smart TV software compatibility

Very often, it is Smart TV owners who experience problems with disconnection, then the reasons for this phenomenon must be looked for in the software.

Often, even at the factory, while testing the device, incorrect factory settings may be accidentally set; among other things, the software is periodically updated, which leads to malfunctions of the TV.

In this case, the settings need to be adjusted or the software reinstalled. The second option requires a USB cable and licensed software.

On a note! To reinstall, it is recommended to use proprietary software from the manufacturer, which can be provided by service center employees.

Applications for Samsung and LG

Samsung and LG smart TVs can download apps from untrusted sites. This leads to software incompatibility and causes equipment malfunctions.

Then you can take the following actions:

1. Remove recently downloaded software.
2. Roll back the installed software to the factory version.
3. Check and, if necessary, clear the built-in memory to reduce the load on the RAM.

Power outages and surges

A surge in electricity may not be noticeable to the average person. This situation is common in villages, country houses, towns and any other place with a poor electrical network.

In this case, the device will turn off on its own a few hours after a power outage. The problem can be easily traced by the blinking of incandescent lamps, but if the device uses LED lamps, the voltage surge will not be noticeable.

On a note! To avoid malfunctions and future breakdown of the TV, it is enough to buy a voltage stabilizer or an uninterruptible power supply unit.

In addition, it is not necessary to purchase the most expensive stabilizer; a weak budget device will suffice, since most modern TV panels consume no more than 100 W of power.

How to clear cache on Philips smart TVs?

You can clean the internal memory storage in a few minutes; there are usually no problems with this. Once you figure out how to clear the cache of a Samsung Smart TV, LG, Philips, Sony Bravia or other popular brands, do not forget to periodically perform this operation before downloading movies or other large files from the network. This will avoid unnecessary problems with content playback and ensure stable operation of the device.

Not so long ago, I began to notice questions in the comments that were written about a problem, more precisely about the “Insufficient memory” error. Which appears on LG Smart TVs when you try to start watching a movie online, playing music, or playing an online game.

Here are two comments that address this issue:

The last comment talks about the “Not enough memory...” problem that appears on the LG TV, model 47LA667V. But, this error can appear on any TV that has a Smart TV function. And I think that not only on LG TVs, but also Samsung, etc. But we will look at the problem specifically on LG TVs.

Serious damage

If the listed troubleshooting options do not help, then the best solution would be to have the device repaired at a service center.

However, if you are sure that you can still fix the TV alone, and you have all the necessary skills for this, you can try to repair the broken unit yourself.

To check the functionality of the functional elements of the TV you need to:

1. Turn off the equipment from the power supply. Remove the back cover of the TV.
2. Examine the node capacitors. After a certain time, electrolytes lose their functionality, dry out or swell, and leak, oxidizing electronic circuit boards. If a faulty capacitor is detected, it is replaced.
3. Check prefabricated units. Due to constant overheating in the traces of the boards, ring cracks and soldering defects will form.

Why does the error about lack of memory appear on LG TVs?

Responding to comments, I wrote that in order to watch a movie or listen to music online, this same movie must be loaded into the TV’s memory. Then, this memory is cleared.

The TV simply does not have enough memory allocated to the browser, so an error appears stating that the memory is full and it is not possible to continue playback. In addition, the error does not appear immediately. This means that as long as there is enough memory, everything works.

I decided to write to LG support and clarify this issue.

Here's what I asked:

As you can see, my guesses were confirmed. TV has certain limitations.
