Your TV turns on by itself, tips for fixing it

Modern TVs have become so smart that they can perform their functions without user intervention. There is nothing unusual in the fact that equipment is turned on according to a schedule or according to a given scenario. But what to do when you did not configure it to perform a task or the model does not have such an opportunity at all, and the TV receiver is already showing excessive independence, turning on, say, in the middle of the night or while no one is at home.

When faced with a similar phenomenon, users make various guesses, and whatever comes to mind at such moments. No, this is not the machinations of the brownie or the uprising of the machines, which your TV has joined. In fact, the source of the problem of equipment getting out of control may be more commonplace. Let's look at the real reasons why TVs can turn on spontaneously and how to deal with it.

Today, almost every home has a television. Sometimes there are malfunctions in its operation, and the TV turns on by itself. What to do in this case is of interest to many. This is a fairly common situation, and its cause is probably trivial and will not require repair.

Reasons why the TV turned on by itself

In addition to the reasons mentioned above, the strange behavior of the TV can be attributed to the following mysterious phenomena:

1. First, pets. Smart parrots, cats, dogs - they love to watch In the Animal World with Nikolai Drozdov. Therefore, do not allow animals near the TV, and avoid teaching how to use the remote control.
2. Let's call the second reason an incident. Many TVs have a timer, although the owners don’t know - it’s not needed - but guests can manage it. Check by chance how things are going with the scheduled activation settings.
3. Understand: we are not alone in the Universe. And although the aliens have peaceful intentions, there is a chance that there are jokers among them. Ask ufologists for more details, read the relevant thematic sites. Remember what Dmitry Medvedev said.
4. The brownie does not like disrespect. Bring a gift so that he doesn’t play pranks. Find out the process of performing the ritual by reading specific mystical literature. We are embarrassed to copy other people’s recipes for fear of causing the wrath of otherworldly forces.
5. Evil neighbors have come up with a way to poison the lives of annoying household members. A probable reason, if only because, as they say, everything can be bought and sold. Or rented out. Perhaps samples for military purposes.

The last section was written more as a joke, because aliens make contact in a different way, animals don’t know how to turn on the TV, the brownie doesn’t care much about modern technology, it’s faster for evil neighbors to make acquaintances in the police and somewhere higher up. Therefore, calm down, update the software, joke on the forums with your fellow sufferers. Have you tried unplugging the plug from the socket? They say it helps.

We hope that now readers know what to do if the TV turns on on its own. And they also know how to competently tell all their comrades in misfortune about this. We hope that the review turned out to be interesting and readable, the film I – Robot, in our opinion, does not live up to Men In Black, which D. Medvedev recommends watching.

No equipment is insured against breakdowns. And even a relatively new TV (but, alas, already out of warranty) can begin to “behave” strangely. For example, turn on and off independently. There may be several reasons for this, and accordingly, there is also more than one way to eliminate them.

The main reasons for turning on the TV yourself

All the reasons why the TV turns on by itself are divided into two groups:

1. Program crash.
2. Hardware damage.

There is a big difference between them. Any user can fix system faults, but special equipment will be needed to fix hardware modules.

The TV sometimes turns on itself after being turned off, not only because it is broken. The most common causes of failure are the following factors:

1. The power button on the remote control is stuck;
2. the internal timer was accidentally set to automatically turn on the television panel;
3. The batteries on the remote control are low;
4. a device is connected (wireless adapter, network module or router), which causes the TV to turn on by itself at night;
5. CEC or HDMI settings can launch the smart TV.

There are many different brands of electrical appliances. Most often, the reason why the TV turns on by itself is one of the above circumstances.

Sleep timer enabled

It is extremely easy to get confused in Smart TV settings. Therefore, we cannot exclude the fact that the user has a direct connection to the arbitrary turning on of the TV. Many people prefer to fall asleep to music videos, movies or TV shows. That's why they use a sleep timer. The bottom line is that after the set time has elapsed, the device automatically turns off.

Why does the TV turn on by itself if the settings timer is turned off? This feature can work in both directions. Therefore, you need to carefully study the settings, mainly because of this reason the TV automatically turns off. How to fix the situation? There is nothing complicated. There is no need to contact the service center. You just need to change the sleep timer settings.

Take your TV remote control and go to settings. Select the "off timer" section. Look at what time you set earlier. Change the shutdown settings or disable the sleep timer altogether. If you want to continue using this feature, then you just need to change the time. It is likely that the time set was incorrect. Therefore, the TV turned on randomly. The device will begin to function correctly immediately after changing the settings.

Features of Samsung technology

Samsung is considered one of the best manufacturers of television equipment. Even this trusted electronics manufacturer cannot guarantee that there will be no operational problems with the equipment. Sometimes the Samsung TV turns on spontaneously. The causes of failure can be very varied:

• failure of the remote control. If the TV receiver does not respond to the control source, you should check that the control option is functioning correctly. It is also recommended to use the camera to check whether the television panel receives an IR signal. When you press any button, you need to take a photo of the remote control. If a bright glow is visible in the image, this means that the device is working properly.
• Installed applications often lead to a crash and the Samsung TV turning on by itself .
  You need to look at the content, and if there are any suspicious programs, look at the settings and remove them;
• If your TV equipment turns off, it may indicate a lack of power. This happens due to constant voltage fluctuations in the power supply, as a result of a broken outlet, or due to destabilization of the power module. You need to make sure that the components are in good condition;
• What should I do if my Samsung TV turns on by itself due to glitches in the old firmware? You should update the software using a flash drive or directly with the options located in the smart TV;
• Often television equipment turns off due to faulty keys on the control panel. It is necessary to eliminate the failure by disconnecting the loop and then checking the equipment for operability;
• Sometimes a Samsung TV turns on spontaneously due to a breakdown in the power source. Here it is recommended to check the board, make sure that the capacitors and other elements are working properly. If defects are detected, damaged components are replaced with new ones;
• The Samsung TV often turns on by itself due to dust and moisture settling. Liquid that gets inside leads to oxidation of the contacts, and ultimately to the spontaneous startup of the device. Dust can cause a short circuit, and therefore the equipment goes into protective mode. In order to prevent this malfunction, it is necessary to regularly wipe off dust and remove moisture;
• If the TV constantly turns off at night, this is due to the fact that Samsung electronics have a built-in “presence element”. If it has not recorded a person in the room for a certain period of time, then it extinguishes the image. If it notices the user, it returns the image back.

Why does the TV turn on by itself at night? Due to an incorrectly set sleep timer. Therefore, it is recommended to study the operating manual and reset the settings to the initial settings or set the timer correctly.

Modern TVs: spontaneous switching on

We suggest you stop fooling around and discard the trivial question of how to identify a malfunction. Just arm yourself with a couple of tricks and use them to your health. It will be clear from the review: it doesn’t matter why the TV turns on by itself. I'm concerned about the method of correcting the situation. The question is what could have broken, since the decision affects the heights of the development of technological equipment. The country does not yet produce smart TVs. Do you want to run ahead of the locomotive? Please!

A modern TV is positioned as a multimedia entertainment center. Some, bypassing the home theater, are equipped with built-in hi-end acoustics. You will get tired of being surprised by 3D, glasses, set-top boxes, catching satellites with live bait, receiving cable television without additional devices. A civilized TV works following network protocols, receives its own IP address, communicates with the server about movies, music, and content. The TV is equipped with special programs, browsers, and Skype-class long-distance video communication applications.

Of course, the colossus refuses to work autonomously; a mysterious well-wisher is in charge of the process. Calm down, the central mind is busy today, Skynet is slow to realize individuality. The central processor is so complex that it has to be equipped with its own firmware, and the software has to be updated periodically. The authors of the development have become wiser: the TV downloads the code according to the schedule. Choosing the dark time of day, every night.

Modern TV

Manufacturers hide failures; after updating the software manually, the problem disappears. It is enough to reflash the device with a flash drive. Canceling the automatic update option helps citizens partially. The problem is limited by a bug. We believe there are a billion real reasons. Viruses, hackers. In December 2013, there was a massive hacking of refrigerators connected by a global network. Hackers were ashamed to finish off the equipment, showing a vulnerability that had been fixed by the developers. We believe that this happens with TVs, the problem is lower in the rank of mass hysteria, it is logical for the manufacturer to hide the bug.

You should download the TV software using a personal computer, take a flash drive, install it manually, and wait for events to develop. For people, taking a step provides a positive result. For some TV models, the service menu is available only in standby mode, when not watching TV shows. Be careful and follow the instructions.

Software

There are other factors that cause the TV to turn on by itself. Often, immediately after updating the firmware, the television screen goes out and then starts working again. This may happen due to the installation of updated firmware, which has flaws, and then it is better to return to the old version. Because of this, the Philips TV turns on itself, this may also apply to other models of television equipment. To automatically disable new firmware, you need to follow these steps:

1. Press the “Home” key on the remote control.
2. Go to the “Settings” subsection and select the “Help” line.
3. In the list that appears, select the “System update” option.
4. Use the remote control to disable the function.

Sometimes you will need to install the firmware manually. To do this, you need to go to the official website of the TV manufacturer and enter the electronics model you are using. Then download the updated objects, transfer them to a flash drive and insert it into the USB socket. After the program is launched, a signal indicating the start of the update process will appear on the television screen. As a result, a reboot will occur and you can use the electronics in normal mode.

Faulty remote control

This breakdown is to a certain extent similar to the situation when the TV power button does not work. It is possible that the “Power” key on the remote control gets stuck or is not pressed the first time. As a result, the device turns on randomly. Problems with the remote control can also be caused by a broken infrared sensor.

There are also more commonplace reasons for the remote control to malfunction. For example, batteries run out. Because of this, it works every other time. In any case, fixing this breakdown will not be difficult. Mostly, remote controls are not repaired, but a new one is simply purchased. If you use a modern Samsung TV, then you can download a special application to your smartphone, with which you can also control your equipment.

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.

Common Causes

If the TV turns on and/or turns off on its own, this may be a typical software-related error in modern technology. Such a malfunction can only be excluded with CRT televisions (although, albeit rarely, this also happens to them). Before you run to the service center, you should try to figure out the problem yourself.

Attention! Any diagnosis requires caution and compliance with basic safety precautions. The equipment should be disconnected from the power supply.

There are two most common reasons why a TV turns off on its own.

• Incorrect device configuration function. There is no reception signal, so the TV turns off on its own. The owner often falls asleep while watching movies (and this is not uncommon), and the TV “thinks” it’s time to turn off. With such an incorrect setting, by the way, a visible malfunction may occur.
• The device has a program installed that sets the on/off mode. But the TV owner either doesn’t know about it or has forgotten about this setting.

Of course, these reasons alone do not explain the malfunction. And if new equipment behaves like this, warranty service will solve the issue, but if you can’t count on free service, you need to urgently understand the problem.

Let's look at what should be checked.

• You just need to look at the tightness of the contact between the socket and the plug. If the plug is not seated tightly, it will periodically move away from the contact, and the TV will turn off. This is especially likely if it turns off as soon as household members or animals move around the apartment. They create vibrations that worsen the already precarious position of the plug in the socket. In such a situation, the TV turns off less often at night. But at the same time it does not turn on itself.

• Dust accumulation. While owners of computers and laptops carefully clean their gadgets and air them out, they often forget about TVs. But dust can also accumulate inside it. In most cases, devices, of course, are protected in the form of a housing with grid openings. They are blocked from dust. But the risk of dust still remains, albeit minimal.

• Problems with the power circuit . First you need to check the standby indicator. If such a part is blinking, then it is probably the power board. Here you either take the TV to a service center or replace the faulty parts yourself.

• Voltage surges . If the TV is used for a long time, cracks appear on its circuit board after some time. And humidity, unstable power supplies, and high temperatures lead to broken connections and swollen capacitors.

• Overheating . It happens due to both unstable voltage and continuous use. The LEDs and insulating winding may be damaged. In this case, the device turns off with a characteristic click.

If all this is excluded, most likely it is the program that is “to blame” . For example, an expensive, newly purchased LG or Samsung TV began to turn on itself, and at different times. And it could be a matter of smart settings. There is an option that the user himself did not disable the software update module, which is why the device configured itself, automatically. Or, for example, a program is installed on the TV that gives the TV a command, so it turns on by itself.

You need to look for the reason yourself, and if nothing is found, then you need to call a specialist.

He must know how long such a malfunction has been manifesting itself, how long after turning off the equipment it turns on again, what diagnostic measures the user has already taken.

How to fix equipment

Why the TV turns on by itself at night is of interest to many television lovers. A few steps that are recommended to be taken to resolve this error:

1. Check to see if the power button on the remote control is stuck. You can disassemble the remote control and clean it well inside.
2. Make sure the batteries are in good condition. Low battery levels often cause random signals to be sent to the television equipment, causing it to turn on or change channels. Batteries can wear out due to frequent key presses.
3. Find the internal timer and set the required parameters. If the LG TV turns on by itself, then go to the “Settings” section of the remote control, where the turn-off and turn-on timer is located.
4. Check the serviceability of the connected cords and devices. It is recommended to turn off devices one at a time at night. And continue these actions until the television panel stops turning on on its own. When the culprit of the problem is discovered, you may need to buy a new cord or the device itself.
5. The TV turns on by itself at night when updating the software. You need to check the availability of hdmi or cec functions on your television equipment.
6. Reset installed settings to factory settings. If the previous steps do not help, it is recommended to try to restore the original TV data. These steps differ for different home screen models, but for popular brands, reset instructions can be easily found on the Internet.

Check event logs

Setting > Style > Use Box: on —> Setting > Style > Use Box: off —>

Sometimes power anomalies occur due to external devices or the CEC command. In this case, you can find out what is causing the TV to turn on by itself by looking at the TV's event log.

Step 1.

Go to Menu and select "Support".

Setting > Style > Use Box: on —> Setting > Style > Use Box: off —>

Step 2.

Tap About TV and select Event Logs.

Setting > Style > Use Box: on —> Setting > Style > Use Box: on —>

Note.

• The About TV item is only available on TVs manufactured after 2021.
• Make sure your TV's firmware is updated to the latest version.

Setting > Style > Use Box: off —>

1. The event log contains “Reason for activation”.

If there is a “Reason for Power On” item in the event log, you can understand why the TV turned on. Your TV can be turned on by mobile apps, sensors, Bluetooth and voice control. You can solve the problem by disconnecting or turning off the connected devices that control the TV.

Setting > Style > Use Box: on —> Setting > Style > Use Box: off —>

• YouTube
  - The reason the TV turns on may be due to applications such as YouTube or SmartThings installed on a device connected to the same access point.

• Sensor
  - Detected and controlled by the brightness sensor in Ambient mode.

• WOL
  - enabled by eMac phy (Magic Packet) feature.

• BLE
  - enabled by the Bluetooth device wake-up function.

Setting > Style > Use Box: on —> Setting > Style > Use Box: off —>

2. There is an entry in the event log “CEC command”.

The CEC function allows you to control devices connected via HDMI with a single remote control. Turning on the HDMI device may cause the TV to turn on. You can resolve the issue by disabling this feature.

Home > Settings > General > External Device Manager > Anynet+ (HDMI-CEC)

Setting > Style > Use Box: on —> Setting > Style > Use Box: off —>

3. There is "one invisible connection" in the event log.

Sometimes the TV turns on/off by itself when the connection is bad (AOC Tilt). In this case, you should carefully check all cable connections between the TV and the OCB.

Setting > Style > Use Box: on —> Setting > Style > Use Box: off —>

Switching channels

It happens that the television panel stops listening and takes on a life of its own. The TV switches channels on its own; modes sometimes stop responding to remote control. This happens for the following reasons:

1. The button on the remote control is stuck. To clarify this problem, the control panel is removed away from the TV. If this helps, then the channels are switching on their own as a result of poor-quality repair of the remote control. If the device has not been repaired, then check the buttons for sticking. Perhaps its edge caught on the body or sunk inside.
2. Intermittent malfunction. This applies mainly to home screens with mechanical keys on the control panel. In this case, it is necessary to open the equipment and check the button board and wire harness. Why do this? To check the buttons, they may not respond at all, or, on the contrary, they may close the contacts slightly. The cause of destabilization is oxidation and independent transmission of electricity. To correct such a failure, you will need to buy similar keys and solder them, or disassemble the existing elements and repair them (clean and rub).

Debugg

You need to look after your TV like any other piece of equipment . And this should be done regularly, for example, not allowing dust to accumulate on any of its parts.

Dust has accumulated

To clean the TV, you cannot use alcohol, alcohol-containing products, or acids , since under their influence the matrix elements will soon fail. Dishwashing and glass cleaning products are also not suitable for cleaning the TV. But you can sometimes use products for monitor screens; consultants at an electrical store will tell you which of these care products are more effective.

Wiping the TV from dust with newspapers is another “bad habit” of the owners . Paper scratches the screen easily, and newspaper fibers may remain on it, which will negatively affect the clarity of the image. Another prohibited cleaning agent is baking soda. Abrasive particles will scratch the screen and cause cracks. And it’s almost impossible to wash it without leaving streaks.

Dust must be disposed of correctly.

• Dry cleaning should be done once every 3 days. This will save the TV from dust accumulation and stains. Microfiber wipes, soft lint-free fabrics (cotton), and special dry wipes for cleaning monitors will help with this.
• After all accessible parts of the device have been cleaned, you should keep the TV turned off for 15 minutes.

Important! You should not use a spray bottle when cleaning the screen: the liquid may end up in its corners and cannot be removed from there. Such cleaning is fraught with serious malfunctions later.

There are problems with the power circuit

A breakdown in the power supply can also cause the TV to turn on/off on its own. For example, the wire is broken, the contacts of the socket are worn out. Because of this, the equipment either suddenly turns off or stops turning on altogether.

If you wiggle the wire or plug while the TV is on, and the picture on the screen disappears, then the cause of the malfunction is in the power circuit. You need to try connecting the TV to a different outlet (you may need an extension cord for this). This way you can find the specific location of the breakdown and it will have to be replaced.

There are voltage drops

When one of the phases of the power supply is overloaded, the following happens: the voltage of one phase drops, the voltage of the others increases. Emergency modes cannot be excluded when the transformer neutral extension cable breaks or when a phase hits the neutral wire. If the house falls into a low phase, then in the worst case, electrical appliances in the apartments may turn off. They will turn on as soon as the potential is equalized.

But increased voltage is more dangerous. The standard network parameters for LED TVs and plasma devices are 180-250 V. If this figure is exceeded, the electronics suffer from overload, and the likelihood of board burnout increases greatly. And this can also cause the TV to suddenly turn off.

The situation can be corrected by installing a socket voltage relay. It can be installed throughout the entire apartment, which means that all electrical appliances will be protected from power surges. You can also install a voltage stabilizer, but such a device takes up a lot of space and looks cumbersome in the interior.

Recommendations from experts

If the TV turns on spontaneously, expensive repairs or contacting service centers may be required. To prevent this problem from occurring, specialists in the operation of modern equipment advise adhering to the following rules:

1. It is forbidden to place the TV near places with high humidity (aquarium, window sill), because water can penetrate the electronic board.
2. Constantly carry out wet cleaning in the room. This will reduce the accumulation of dust on important electronic components.
3. The TV turns on by itself if it is not unplugged from the outlet.
4. When using household appliances, it is advisable to ensure that the pressing force on the remote control keys is reasonable. Do not hit the buttons or squeeze them out of the base.

If a Sony TV (or another brand) turns on by itself, troubleshooting the problem will not be difficult. The troubleshooting methods for any TV model are the same.

The main factor why the TV turns on by itself is that the options are not set correctly. This problem can be easily corrected with the appropriate settings. If the failure is more serious, it is recommended to contact a service center for specialist help.

Non-working buttons

There are often situations when the “Power” button located on the front panel of the TV gets stuck and cannot be pressed. This occurs as a result of mechanical damage. Sometimes a key is pressed but does not work. Most likely the cable was damaged. Be sure to check the functionality of the button. Because problems with it can cause the TV to turn on spontaneously.

The damage can be corrected by replacing the key. Users may have problems with this. First, you need to purchase a button that will fit your TV model. Secondly, the broken key must be carefully removed, and then a new one must be connected. To do this you need tools and skills in carrying out such work. Therefore, if you are unsure of your abilities, then contact the service center.

Dust and moisture inside the TV

A common reason why a Samsung TV turns on and off spontaneously is dust accumulated inside or moisture from the room air that has settled on the contacts of component modules.

Dust has excellent electrical conductivity; even a small amount of it can lead to an arbitrary short circuit, which turns on the protective mode on the TV.

When exposed to moisture, the contacts oxidize and corrosion forms on all metal parts. This leads to unevenness of the transmitted signal.

You can eliminate this cause in the following ways, after first disconnecting the TV from the electrical network:

• Using a vacuum cleaner. It is enough to move the suction tube without an attachment or with a furniture brush attachment along all existing holes for three to five minutes at the maximum speed of the vacuum cleaner. Samsung has provided most models with special holes on the back panel of the TV, allowing for the removal of accumulated dust and moisture.
• Using a soft brush. This method is used for severe contamination. To do this, you need to remove the back cover and carefully, using a brush, remove all the accumulated dust and dirt from the parts of the TV.
• Dry the moistened contacts using a conventional hair dryer, directing the pressure of hot air to the moistened areas.

If such manipulations do not help, and the malfunction remains, replacement of microcircuits, boards, controllers and other parts deformed due to exposure to static electricity and moisture is required.

You can make the replacement yourself if you understand how to solder contacts, but it is better to leave the TV in the hands of a specialist.

Solving the problem yourself

If all of the above factors do not apply, you can try to find the reason yourself. To do this, it is enough to have basic skills and knowledge in electronics to fix problems with wires or sockets. Step-by-step instruction:

1. You need to make sure that all buttons on the device can be pressed freely and are not pinched or pressed.
2. Turn off the TV, unplug the cord from the outlet and after a couple of minutes turn the device back on.
3. Go to the timer settings and check if all settings satisfy the user.
4. If the box continues to turn on randomly, you need to update the software (to do this, you need to find a file with the appropriate updates on the Internet, download it and transfer it to the TV using a cord. Then open the file on it and install the software).
5. If the previous steps were unsuccessful, you can replace the power supply, which in most cases solves the problem.
6. As a last resort, if all else fails, contact a specialist.

Why does the TV turn on and off on its own?

Failures associated with the power supply manifest themselves as follows: the TV cannot be turned on, the red power indicator works, but the device itself does not respond to either the remote control or pressing a button on the panel. If the TV is not in sleep mode, the socket and contacts are in order, then you need the help of a TV technician who will check the operation of the power supply.

Random switching on and off can be caused by a number of breakdowns:

1. Failure of the power supply board. Most often, the board breaks due to leaking capacitors, which causes unstable operation of the TV. Capacitors, in turn, deteriorate due to increased modes, or due to the long “standby mode” of the TV. Therefore, after watching TV, always turn it off without leaving the standby mode, because a still frame or a beautiful picture on the monitor reduces the service life! This type of repair is quite simple. A TV repairman will simply change the capacitors. Even though this is a simple type of repair, never trust it to an amateur repairman! Capacitors can explode if the polarity is reversed when replacing them!
2. Operational heating. Depending on the unstable voltage in the network, various components of the TV may heat up. The first to suffer are diodes, insulating windings and capacitors. Due to overheating, an electrical breakdown may occur, which will automatically turn off the TV, as the electronic fuse system will trip. When the fuse turns on and the TV turns itself off, you can hear a characteristic sound in the TV body, similar to the click of a button. Only an experienced TV repairman can accurately diagnose the problem and competently repair a TV with this breakdown.
3. The TV turns on by itself because a software update is required. You need to download the necessary programs and insert the USB flash drive into the connector in the TV case. Some TV models open the general menu only in a special mode (most often this is standby mode). Updating the software may solve the problem of spontaneous startup.

In order to finally solve the problem when the TV turns on and turns off on its own, it is necessary to take a number of measures. If you turn off the “software update in standby mode” function, then you will not need a TV repairman. If, after all the steps taken, the TV still turns on by itself, then you need the help of a qualified TV repairman.
