Not a single manufacturer has yet achieved the goal of creating ideal products. All existing equipment sooner or later wears out or, even worse, breaks down. Sometimes this happens due to careless use, sometimes due to defects. In fact, there can be a huge number of reasons, so it’s better to figure them out right away, because even an inexperienced user can deal with problems on their own in some cases.
TVs can also sometimes malfunction. Sometimes problems are unpredictable and can frighten the owner of the device. For example, a Samsung TV turns on and off on its own. If something like this happens for the first time, anyone will be scared, especially if it happens at night.
Problem
Why the Samsung TV turns on and off on its own is not easy to figure out. But there are several reasons for this phenomenon. Sometimes this way you can fix the problem yourself. But in most cases it can be technically complex, so only a specialist can cope with it.
If you notice that the TV has begun to “take on a life of its own,” there is no need to panic. Although this is not the most common problem, it does occur in some device models. Therefore, ways to solve it have already been found.
Simple failure
If a Samsung TV turns on and off on its own, this does not mean it is permanently damaged. A similar problem often occurs in modern device models. Even some already outdated devices can behave this way.
Sometimes the device turns off when the user turns it on. Sometimes it activates on its own and then goes out. But the reason is not always a technical failure. Sometimes the culprits are:
- Errors with device settings.
- Setting up a special utility.
In the first option, the problem may be in the enabled automatic option, which is designed to turn off a device that does not pick up reception signals. For example, you turned on your favorite TV show and didn’t pick up the remote control for a certain time, didn’t switch or even adjust the volume. Shutdown usually occurs after 2-4 hours.
In the second option, the option may have been set to turn off the TV after a certain time.
Troubleshooting
To prevent this from happening, you just need to understand the device settings. The TV menu usually lists all the main technologies that are available in the model. You can also change and customize existing features.
It’s worth saying right away that the reason for this behavior of the device may be another problem. For example, electrical problems can cause errors. If the outlet is of poor quality or unreliable, it may supply unstable electrical voltage, which will affect the performance of the TV.
In this case, you will have to check the voltage. To do this, you need to either invite a specialist or acquire a special device that will show the stability of the current.
Power supply problems
Can the TV turn on by itself as a result of a failure of the power supply? Experts say that this factor is one of the likely causes of malfunctions in Smart TV brands such as philips or sony. The battery breaks down due to constant power surges or a faulty outlet. Before fixing this hardware failure, it is advisable to carry out diagnostics. To do this, remove the back cover, and if there is soot on the power source, it means the element has burned out.
Replacing a component will require special skills in electronics and physics. Otherwise, it is better to contact a service center, where competent engineers will quickly install a proprietary component. If the power supply is changed independently, and the TV turns on by itself, then they call an electrician.
Faulty power supply
If your Samsung TV turns on and turns off immediately, you should look for the problem in the power supply. Experts recommend diagnosing the indicator. For example, if in the standby menu the device light reacts to being turned on but blinks, there may be problems with the power supply. Although sometimes the problem may be related to the breakdown of other parts of the device. You will have to take the TV to a service center.
The indicator may be constantly lit when turned on. There may be a problem with the TV's power supply. The power supply unit refuses to respond to user commands, and accordingly, the indicator will not manifest itself in any way.
The TV turns on and off on its own
Television plays an important role in social development and the transmission of information, so malfunctions in its operation can cause a lot of inconvenience. Sometimes the TV turns on and off on its own .
One of the companies that produces and distributes the best TVs is Samsung. The Korean company actively follows modern technologies, pleasing consumers with quality, and producing high-quality LCD displays, mainly of the LED type (widescreen, curved and other newfangled ones). But even such a good manufacturer sometimes has problems related to the operation and normal operation of equipment. One of the most common breakdowns is that a Samsung TV turns on and off on its own.
In the article we will analyze the problem of why the “plasma” spontaneously turns off and on, starting to work worse over time. Let's start by analyzing the factors that cause such problems.
Reasons When using complex equipment, gadgets and electronics, failures that are incomprehensible to the average user are possible. The reasons can be completely different: from independently changing the settings in the menu, to problems with the hardware component. Accordingly, the problem of randomly turning on and off the plasma can be: Changes in settings.
Complex breakdowns
If your Samsung TV turns on and off on its own, you will have to think about more serious consequences. Sometimes this behavior is caused by low signal reception frequencies. Often this is why the TV works at one time or another.
For example, one TV channel can work perfectly until the device itself goes into standby mode. On another channel, the same story will be observed when there is not enough frequency, so the device only works for a couple of minutes.
Complex problems include:
- tension problems;
- inverter failure;
- board contamination;
- software failure.
Cleanliness of the device
If your Samsung TV turns off and turns on spontaneously, you should think about cleaning the device. Few users understand that it is necessary to treat any equipment with care. Dust or dirt may cause damage. Therefore, it is important to maintain your TV regularly.
How can ordinary dust harm you? It can hardly be called an effective conductor, but even a small amount can be enough to close contacts. Therefore, it is better to use a vacuum cleaner or a can of compressed air.
If you have never cleaned your TV, it is better to invite a specialist. But you can do everything yourself: just remove the back panel and carefully clean the device board.
Malfunctions in electrical circuits
Smart TVs are electrical devices and the cause of problems may be faulty sockets and electrical networks in the house. The phenomenon is associated with the general power grid and power surges. Changes negatively affect capacitors and diodes, which are responsible for the screen and the ability to turn on and off. This type of problem cannot be resolved on your own.
Perhaps it is due to interruptions in the power supply to the inverter. After all, any, even the most minimal, crack or scratch on microcontrollers and microcircuits can lead to voltage surges inside the equipment. Carefully inspect and diagnose the TV parts for external damage, and if any defects are found, contact a technician.
Problem with the power supply
If the Smart TV does not respond to the on/off button on the remote control, and the red standby indicator constantly turns on and off, then the above reasons include a malfunction of the power supply. Although televisions of this type are of high quality, this is one of its most vulnerable elements.
The reasons for the malfunction of this part may be power surges in the network or breakdown of sockets in the house. Anyone can see what's wrong with the block. Open the back panel, and if the component has become unusable, you will immediately see that its surface is swollen and blackened.
You can replace the module yourself only if you have the appropriate education or knowledge in physics and electronics. If they are not there or you do not want to put your equipment at risk (and yourself too), then you should contact a service center. There they will figure out why the device turns on spontaneously. If this is due to a damaged power supply, the craftsmen will quickly solve the problem by replacing it with the original.
If after changing the power supply nothing changes, call an electrician to have a specialist check the voltage in the outlet and adjust the operation of the power supply system in the house.
Inverter problems
When a Samsung Smart TV turns off and turns on on its own, it’s worth thinking about the functionality of the inverter’s power circuit. As practice shows, this is one of the most common problems that arises due to cracks on the board.
Cracks may appear due to:
- unstable voltage;
- overheating of elements;
- temperature fluctuations;
- excessive humidity;
- problems with the capacitor.
It is best to resolve all these issues with a specialist, since without the proper knowledge and experience you will not be able to fix everything yourself.
Problems in the power system
The TV may malfunction during operation, turning itself off and on due to problems in the power system.
The main types of violations in the TV power supply:
- Constant false contact in the socket. Make sure that the plug and socket are in good condition and connected correctly.
- The power cable is in poor condition. Check that there are no false contacts or breaks or cuts on it.
- Check that the power cord is connected correctly to the back of the TV
- Power surge or faulty power supply. Usually the most common problem that allows Smart TV to turn off. Due to a surge or peak voltage, the TV may turn on, especially if it is old or the power supply capacitors are damaged.
- Another, somewhat commonplace mistake is that the plug the device is connected to has too many cables from other devices connected, causing problems. You can try connecting them to other connectors to determine the cause. And in the future, buy an extension cord or plug with a timer to prevent unauthorized switching on.
- Damage to the HDMI cable, Ethernet cable, or antenna cable. Check the condition of the cables, especially the plugs and wire insulation; perhaps the problem is electrical, and not a defect in the receiver.
Troubleshooting
Depending on what causes of the breakdown were found, they should be eliminated. First, it is recommended to check the integrity of all connections: router, antenna and power cable. Next, you can begin to inspect the board. What should you pay attention to?
First, you should look at capacitors that may swell. They look like AA batteries. Their shell should not be damaged, and their shape should be cylindrical, without bumps or cracks.
If there is rust on the contacts, it is better to clean everything yourself. To do this, it is enough to use alcohol wipes. If there are problems with the capacitor, power supply or cable, you can purchase everything yourself at the store and replace it.
If none of the above helped, it is better to contact a service center. Experts can find more complex problems and help fix them.

Solving the problem on your own If you find one of the above reasons that suits you, then in most cases it is possible to solve the problem that causes the Samsung TV to turn on by itself on your own.
To do this, you need to have basic knowledge in the field of electronics in order to be able to deal with broken contacts or an incorrectly installed socket.
But if you do not want to put your life and health at risk, then it is better to use the services of a service center and then take measures to prevent such problems in the future and set up an electrical network at home.
Step-by-step instructions: Make sure that the buttons have free movement and are not jammed or broken. We reboot the device - unplug the plug from the socket and wait a couple of minutes. We check the timer parameters in Settings (we discussed how to do this above). If your Samsung TV keeps turning itself off and on, try updating the software. We replace the power supply.
As a last resort, we go to the workshop. Conclusion So, we have examined the reasons for the spontaneous switching on and off of plasma power. Let's summarize what needs to be done to avoid such a problem: Periodically clean parts from dust and monitor the level of humidity in the room. Set the correct time for the sleep timer.
Monitor device software updates. If possible, avoid power surges or malfunctions of sockets in the house (this can be solved by purchasing a Resant voltage stabilizer and others).
If the plasma turns on and off endlessly without the user’s knowledge, even after following the above recommendations, then you should not resort to DIY repairs. Most likely, the breakdown is not related to any of the factors described, or you did something wrong.
It is recommended that you contact a Samsung certified service center. They will provide high-quality advice and ensure proper professional repair of the device, with a guarantee of normal operation for a long time.
