Smart Samsung TV itself turns on and off

How to remove spontaneous inclusion of TV

Modern TVs have become so smart that they can perform their functions without the participation of the user. The fact that the technique is turned on according to the schedule or according to a given scenario, there is nothing unusual. But what to do when you did not set it up to complete the task or such an opportunity for the model is completely absent, and the television receiver shows excessive independence, including, for example, in the middle of the night or so far no one is at home.

Faced with a similar phenomenon, users build different guesses, and that just does not come to mind at such moments. No, these are not the machinations of the brownie and not the uprising of the cars to which your TV joined. In fact, the source of the problem of getting out the control of control can be more banal. Consider the real reasons why TVs can spontaneously turn on and how to deal with it.

The reasons for the reboot

During the operation of complex equipment, sometimes incomprehensible to the ordinary user failure.

The reasons can be completely different. From spontaneous changes in the settings in the user menu to system failures.

Let us dwell on each of them a little more details.

Installed applications

The Smart TV application often becomes the reason that television equipment is launched on its own. In this case, the restored content should be inspected and, if any suspicious programs are found, check the settings and immediately remove them.

The malfunction of the remote control

If the TV receiver turns on and turns off without any participation of its owner, while not seeing the remote control and does not respond to commands, you should make sure that the option of long-term management works correctly. In addition, it is necessary to check whether the TV signal perceives the TV, the usual cell phone can help in this. As you know, the human eye does not see infrared rays, but this can do the camera. To conduct diagnostics, you need to photograph the remote control at the moment when you press any button: if the image has a noticeably bright glow, then the remote control works properly.

Power cord and sockets

Когда TV-приемнику недостает энергии, получаемой из электрических сетей, то после включения он будет тут же выключается и многократно перезагружаться.

This happens with frequent voltage fluctuations in the network or due to interruptions in the operation of the power supply, as well as in case of malfunction of the outlet.

It should be made sure that the cord is not damaged, not too much and gnawed by pets, in addition, you need to check the connector and plug and integrity, pay attention and fork. It is possible that it is charred. Pay special attention to the diagnosis of the condition of the outlet: try connecting the TV to any other outlet, so you can make sure if the malfunction remains or not.

Checking external devices

At the next stage, you can check the functioning of the Samsung LCD TV with the external devices disconnected (Wi-Fi router and antenna). It is possible that the sleeping mode is set on the router, in which case the television receiver will turn on and turn off spontaneously in vain attempts to restore the Internet connection.

Software Update

Often the cause of the malfunction is the old firmware. In this case, it is necessary to update the software, this can be done through a flash drive. In this case, a new version is previously loaded in it or if the receiver is equipped with a Smart TV function directly in the menu. If an automatic update option is activated on the panel, then each user may probably notice that from time to time the LCD TV screen begins to glow, and then fades away. This means that the unit checks its system for new versions of software, is engaged in their installation, and then disables them. In order to prevent this function does not interfere with viewing programs, the mode must be disconnected.

Falf in the control panel

One of the typical breakdowns that often occur with the TV is associated with a malfunction of the buttons on the control unit.

If at least one of them does not work, then the system includes a protective mode. In this case, the user notes that the television receiver after turning on begins to restart on his own.

To eliminate the malfunction, you should turn off the train from the control panel and check if the equipment works.

Field breakdown

The malfunction of the power supply is another very common cause of spontaneous launch and disconnecting the television receiver. In this case, you should carefully inspect the board, check the condition of the capacitors and some other elements for defects. If they are found, they should be replaced with working. If the user has no skills of such work, then it is better to contact a professional master.

Dust and moisture

As you know, dust has the ability to conduct current and create static electricity around itself, which can lead to a short circuit. In such a situation, the technique goes into protective mode. The ingress of any liquid into television equipment causes contacts of contacts, which, in turn, leads to spontaneous inclusion and disconnection of the technique. In order to prevent the appearance of such a malfunction, it is necessary to remove moisture as soon as you find it on the surface of the device.

Prevention

Any problem is easier to prevent than to eliminate. To extend the life of the TV, follow the following rules:

  • Regularly wash the dust from the screen and body.
  • Make sure that the room with the TV is normal humidity.
  • Do not install dubious programs.
  • Periodically update.
  • Do not allow a fall or other mechanical influences on the TV.

You can mainly eliminate the cause of the spontaneous shutdown of the television receiver yourself. Most often, the problem causes a malfunction of the control panel or update of software. Therefore, when working with equipment, be careful and do not neglect the rules of operation.

Fault prevention

To save the TV in a working state and avoid subsequent repairs, adhere to the following recommendations:

  • Do not install the TV near places of accumulation moisture: aquarium, window sill, air humidifier. Put mugs and vases away.
  • Check the settings for the inclined sleep timer or awakening according to schedule. Turn on the protection mode from children so that they do not accidentally change the parameters of the system or not set dubious software.
  • Wet cleaning in the room will reduce the amount of dust and the chances of its penetration into the body. Moisturizers and air purifiers act in a similar way (see the first recommendation).
  • During downtime, disconnect the TV from the network, this will protect it from stress jumps. The alternative will be the use of a network filter or stabilizer. Relevant for residents of the private sector, where often an unstable voltage supply.
  • Follow the exit of the updates and do not tighten with their installation. They help get rid of the shortcomings of the previous version, including the arbitrary “life” of the model.
  • Periodically disassemble the device to clean it from the inside, inspect the state of the motherboard. Carry out and inspection only after the guarantee, otherwise arbitrary opening of the case can be canceled by the guarantee.
  • Carefully use the remote control. Try not to press the keys, do not drop it to the floor, keep it away from the water.
  • Do not forget about safety measures when it is necessary to inspect the nutrition elements for defects or damage.

Cases when the TV turns on and immediately turns off among the models of all brands and are the cause of “external” factors or failure of the motherboard. In cases where the source of the problem remains uncertain, experts recommend contacting the service center or replace the device under warranty.

Elimination of failures

So that this does not happen, you just need to figure out the settings of the device. The TV menu usually shows all the main technologies that are available in the model. You can also change and configure the existing functions.

It is worth saying that the reason for this behavior of the device may be another problem. For example, malfunctions of the mains can lead to errors. If the socket is poor.Quality or unreliable, it can supply unstable electric voltage, which will affect the operability of the TV.

In this case, you will have to check the voltage. To do this, you need to either invite a specialist or get a special device, which will show current stability.

Wi-Fi disappears

Problems with a wireless Internet connection can occur not only due to a breakdown of the adapter Wi-Fi, but also due to software failures, incorrectly set settings. The fact that the cause of the problem was the marchutizer cannot be ruled out. Try connecting to the home network using other devices, for example, smartphone. If everything works, then LCD TV Smart TV requires replacing the Wi-Fi module, for this, contact the service center.

Common reasons and their solutions

Understand what to do if the Samsung, LG or other brand TV turns on and immediately or after some period of time turns off, you can only find out the cause of the phenomenon. Further actions that will need to be performed to eliminate the problem depend on it. First of all, you need to figure out why the TV is turning off on its own, so the most important point of events is the correct diagnosis.

Consider the common causes of the problem when Samsung or another television receiver turns on and turns off itself, and solutions that are effective in specific situations.

Samsung TV Turns Off By Itself Randomly. What To Do? [SOLVED]

Broken buttons

One of the most common reasons why the TV is spontaneously turned on and off is a malfunction of the power button. And the shutdown can follow immediately to turn on the device. Jamming, setting buttons and other oddities when pressing signal that the detail requires replacement.

The sunk button “Power” on the remote control can also be source of the problem. Typically, sticking or irregular key response is the result of contamination of contact surfaces, but sometimes the malfunction is associated with mechanical damage. In the first case, it is enough to disassemble the control device and clean the contact elements with alcohol, in the second, the problem can be solved by the voltage of contacts on the board. Sometimes we can talk about the malfunction of the infrared sensor.

Repair requires special skills, therefore, in their absence, you will need the help of a specialist, as an option, you can buy a new device of the DU, which in some cases will cost cheaper than restoration of the old remote control.

The jump in the tension

Electric voltage drops are one of those factors that lead to the most diverse problems of technology, including the phenomenon when the television receiver itself turns on and turns off immediately or after a certain period of time.

Voltage jumps and outlets in the mains are often found in houses with the old electrical wiring and can contribute even to the speedy failure of the device. If possible, it is better to replace the wiring, which will be useful for all devices in the house. Another, less costly solution, may be the purchase of a voltage stabilizer or uninterrupted power supply, and it is not necessary to purchase a powerful device, it will be enough to compensate for the voltage by the budget model, since for the most part modern TVs do not consume up to 100 watts.

Sleep timer

A common reason why the Samsung TV itself is turned off is an activated sleep timer, and it is not necessary to deliberately and not always you. You can turn off the function in the Smart TV settings, for which, using the remote control, you need to proceed to the section “Timer of the shutdown”. If necessary, you can set another shutdown time or deactivate the option.

Software

In the case of “smart” devices with a cut, the reason why the TV turns on and immediately turns off may be software errors may be. These can be the consequences of the update, incorrect firmware or incorrect factory settings. You can change the settings, roll back to the previous version of the firmware if the trouble appeared after the update, or perform the system update manually. The current version of the software should be downloaded from the official web resource of the manufacturer, then you need to load the distribution to the USB flash drive or other drive, connect to the television receiver and start the installation process. Upon completion of the installation of the system and drivers, the TV will be rebooted, and if the problem was incorrect firmware, it will be solved.

Dust and moisture hit

You cannot underestimate such a serious enemy as dust. Although it itself is not considered conductive, but, forming the accumulation of pollution, and, even worse, in tandem with moisture can lead to a short circuit of contacts on the board and overheating, burning out semiconductor components. For this reason, the television receiver often turns off a few seconds after turning on, and regardless of what the model you have, the old kinescope or modern.

In the case of dust settlement, the problem is solved by cleaning, which is easy to carry out at home using a vacuum cleaner and a small brush. To remove accumulated dust, you need to remove the rear cover of the device.

Moisture has a destructive effect on the internal elements, leading to consequences such as a short circuit, oxidation of contacts and burning out modules. To eliminate the problem, it will be necessary to arm yourself with a soldering iron in order to clean the contacts of oxides and break them again. The paths are restored by solder or with a jumper of thin wire. We do not recommend performing a similar procedure without appropriate skills.

Non.Terrain malfunctions

Another of the common reasons why the device turns off a few seconds after turning on or does not turn on at all is a cable malfunction or socket contacts. Check it is quite simple, moving the food wire and the fork in the outlet. When identifying the problem (the device will react with switching on and disabling), connect the device to another outlet, thereby determining which elements need to be replaced or repair. External inspection of the cord is necessary, although it is not always possible to visually determine the damage. When detecting creases or other defects, it should be replaced.
