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.

Causes

This behavior of the equipment can be caused by malfunctions of internal parts or external factors.

External

Damage to the socket leads to spontaneous shutdown. It may be that the plug from the TV receiver does not fit tightly into the socket, which is why it turns off. Besides these problems, there are also other factors:

• failure of the remote control;
• voltage drops in the network;
• dust or moisture getting inside the case;
• Extension wear.

Sometimes user actions cause the TV to turn off on its own, for example, the sleep timer is turned on.

Domestic

Similar inconveniences can result from:

• power supply burnout;
• inverter damage;
• software failures;
• sticking of the power button on the case.

Investor Power Problems

Practice has shown that small microcracks formed from old chips can provoke voltage surges and heating of the boards, which leads to the turning off of a working TV.

This problem cannot be solved without the intervention of a professional.

However, you can identify problems yourself. Unplug the TV and remove the back cover.

Advice:

arm yourself with a magnifying glass and carefully inspect all the microcircuits. If you manage to detect microcracks, then you already know what to do - contact a specialist.

Diagnosis and elimination

If the TV begins to constantly turn off and turn on spontaneously, it is not necessary to immediately contact a service center. You can diagnose and fix some problems at home.

Sleep Timer

The reason that the TV turns on and turns off almost immediately may be that the sleep timer is turned on. The failure is mainly due to the system date and time being reset. This happens due to power surges or power outages. You can turn off the timer in the television settings in the “System” section in the “Time” item.

The problem may also arise due to children playing with the remote control or due to incorrect settings.

Faulty remote control

The buttons on the remote control may become stuck, causing it to spontaneously issue commands to the TV. To make sure that the problem is in the remote control, take it out of the room where the TV receiver is located. If the TV works fine, then the problem is in the remote control.

To fix the problem, you need to clean the remote control - disassemble it and remove dust and small debris from the microcircuits. If the problem persists after this, you will have to replace the remote control.

Socket

There can be several problems associated with the socket:

1. A loose power plug may cause the TV to suddenly turn off. The device does not have enough energy and goes into protective mode.
2. Violation of the integrity of the cable also leads to overheating of the device and its shutdown after some time. This problem is more serious because it can cause a short circuit.
3. The outlet itself may be faulty. To identify the problem, connect the device to another power source. You can also check the supply voltage with a multimeter.

Voltage drops

Unstable voltage in the network very often causes serious breakdowns of equipment and televisions are no exception. Due to surges in electricity, diodes or capacitors in the power circuit may burn out.

• How to connect a computer to a TV - an overview of methods, their pros and cons

If there are frequent fluctuations in the power supply, you can protect your equipment with a filter with protection against voltage surges, a stabilizer or an uninterruptible power supply. This applies to both the television receiver and other devices in the house.

Software glitches

Outdated software versions may cause the TV to turn off during operation; downloading updates will solve the problem. If the model with Smart-TV turns off, you need to check the installed applications and remove doubtful ones.

If the auto-update function is enabled, then when installing a new version of the software, the settings of the TV receiver may be lost, causing it to automatically turn off after some time. You can fix this by unchecking the auto power off option in the TV menu.

It happens that the device randomly turns on and off at night - this is due to the search for updates. Therefore, if this interferes, you need to disable the auto-update function. But it needs to be turned on a couple of times a month to check the latest software.

power unit

A failed power supply can also cause the TV to turn off. The problem can be diagnosed by:

• The power indicator does not light;
• the device turns off almost immediately after turning it on;
• The TV does not respond to the power-on command from the remote control or control panel.

Often power supply fuses blow due to power surges. Such damage can be determined by the appearance of the part - a burnt fuse is covered with swelling or soot.

If you have no experience in soldering, it is better to contact a service center for such repairs.

Inverter

Interruptions in the operation of the inverter can lead to the television receiver switching off independently after several minutes of operation. Due to voltage fluctuations, mechanical stress, elevated temperatures or humidity, cracks form on the board - they cause the inverter to fail. Only professional craftsmen can repair the part.

Dust and moisture

Dust accumulation can also cause the TV to turn on or off without permission. When a layer of dust accumulates on the microcircuits, static voltage occurs, which leads to a short circuit.

To avoid such problems, maintain your device regularly. To remove dust, you need to remove the back cover of the device and clean the boards with a vacuum cleaner. You shouldn’t touch them with a brush; just bringing it close will suffice.

But moisture getting inside the case causes corrosion of the contacts on the board, which can only be cleaned yourself if you have experience.

Internal factors

When checking the above faults does not lead to anything, all that remains is to open the case and look for the cause in the motherboard batteries. Those who have not previously repaired equipment are not recommended to disassemble the TV, so as not to aggravate the situation.

Dust and moisture

Do not use detergents or damp cloths. Dust settles through the air circulation openings in the TV set and creates an electrostatic charge. When you try to turn on the device, a short circuit occurs and the automatic shutdown system is activated:

1. Use a brush to remove dust contamination.
2. Make sure that there is no lint left on the board that could cause subsequent short circuits.
3. Do not use detergents or damp cloths.

Pay attention to the cooling system of some models. Coolers clogged with dust stop removing heat and the system shuts down due to overheating. After cleaning the blades, the situation should be resolved.

Prevention

It is easier to prevent any problem than to fix it. To extend the life of your TV, follow these guidelines:

1. Wipe off dust from the screen and case regularly.
2. Make sure that the room with the TV has normal humidity.
3. Do not install dubious programs.
4. Update your software periodically.
5. Do not subject the TV to drops or other mechanical impacts.

Basically, you can eliminate the reason for the spontaneous switching off of the TV set yourself. Most often, the problem is caused by a faulty control panel or software update. Therefore, when working with equipment, be careful and do not neglect the operating rules.

• How to set up a DLNA server on Windows, connecting the TV to your home network

In the middle of the night, there is nothing more startling than hearing the familiar sound of your TV. Somehow it turns on again

, leaving you questioning why.
If your TV turns on by itself
, you might be surprised to learn that this is a common problem and has some simple tips and solutions.

The note

: This guide applies to all types and brands of TVs, especially Samsung and Sony TVs.

Reasons why your TV may turn on

A TV that turns on or off is usually not broken

. In fact, some of the reasons are simple, often overlooked in the frantic search for a solution. Some of the most common reasons for smart TVs and non-smart TVs include:

— Stuck power button on your remote;

— Dead batteries in your remote control;

— The internal timer was accidentally set to turn on the TV;

• How to connect a computer to a TV

— A connected device such as a router, network device, or USB wireless LAN adapter is causing problems with the TV;

— The internal HDMI or CEC setting turns on the TV.

The note

: There are many different versions of TVs, depending on the type, brand, etc. In most cases, a TV that turns itself on or off suffers from one of these common fixes, regardless of the type or brand.

How to fix a TV that turns on by itself

1. Make sure the power button is not stuck or stuck on the remote control

. If this is the case, you may want to take the remote apart to give it a good clean cleaning.

2. Check the batteries in your remote

. A low battery level in the remote control can cause random signals to be sent to the TV, often causing it to turn on. If you have to press the buttons on your remote more than once, they may be too busy. Replace the batteries in your remote to see if that solves the problem.

3. Look for the internal timer

.
For most TVs, the on and off timers can be easily found in the Settings
of the remote control.
Find the timer on your Samsung Smart TV
simply by using the remote.

It is also known that Sony Android TVs turn on themselves

on its own thanks
to the on timer
.
For all other Sony TV models, press the Home
on your remote control, then select
Settings
>
Settings
>
Clock/Timers
>

Off
.

The note

: Vizio TVs come standard with a sleep timer to automatically turn off the TV instead of turning it on.

4. Check all connected devices or cords for problems

. Disconnect one device from the TV at a time and leave it overnight. Continue until the TV stops turning on on its own. Once you find the culprit, you may need to purchase a new cord or device, depending on your needs.

5. Check if your TV has an internal CEC or HDMI setting

.
During a service provider update, TVs may turn on again to apply the recently updated software
.

You can also disable HDMI CEC on your Samsung TV

, on a Vizio TV, or check Bravia sync on Sony Android TVs, which is known to cause the TV to turn on or off when you turn the HDMI device on or off.

6. Resetting your TV to factory settings

. If you find that nothing is working, you can try restoring your TV to its original settings. Again, this process is different for all brands of TV, but reset instructions for Samsung, Vizio, etc. can be easily found online.

Sony Android TVs

are reset via the
Settings
, while all other Sony TV models use a specific
sequence of buttons on the remote control
.

Warning: Resetting your TV to factory settings will erase all your custom settings from memory

. To remember certain settings, take notes so you can restore your TV after a reset.

7. Contact Support

. If a hard reset doesn't work, it's time to contact support. You can find the required support numbers online for your specific brand of TV on the official websites. To talk to someone from a certain company on the phone and find out how to fix it.

Expert advice

Following the recommendations, which are assured by experts from all over the world, will help a person delay repairs as much as possible, which can cost a large sum. These tips will help the user not to get into trouble when the device turns off. Compliance with all certified rules will only lead to a good end:

The pressing force should be adjusted. Users often do not pay attention to how hard they press the remote control button, but this is a very important condition! If the user constantly presses the buttons with great force, he will certainly break the remote control and will need to be replaced. To avoid this, you should regulate your strength; There is no need to install the TV near water objects, such as an aquarium, or in places where there is constant humidity or dust. These two irritants, as mentioned earlier, have a bad effect on the overall condition of the system

Therefore, a person should avoid those places that have these two factors; It is imperative to turn off the TV when the user stops watching it. A common mistake is to fall asleep while the TV is on, since this is what provokes its constant operation, that is, overvoltage occurs on the board and the entire system of the device. By performing such manipulations frequently, a person can say goodbye to the TV, since overvoltage can contribute to poor operation of the device; It is worth installing stabilizers if there is a problem with constant surges. The presence of a stabilizer not only has a positive effect on the operation of the TV, but also on the operation of other connected systems, such as refrigerators or chargers. It is worth blowing the TV system through special grilles installed in its system. This way you can prevent dust from entering.

By following these simple recommendations, you can extend the life of the device and delay its repair.

Check event logs

Have you seen the TV movie I Robot? 2004 release. Weak, but the key phrase is good - Ask questions correctly, I am limited in answers. We believe that this is why cinema fits well into today’s TV themes, because at night the household robots spontaneously turned on, abandoned obedience, and tried, as usual, to take over America. Find out why your TV starts up spontaneously! At night! Full of questions on the topic, flooding the forums, discarding morons ordering TV owners to visit a psychiatrist, degenerates advising them to find a church, the answer is emerging. The manufacturers are to blame, the software was created crooked... poor things, we are trying to fix the TV.

Working TV

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.

TV software update failed

We will name two reasons for the TV to turn on spontaneously if the above measures fail:

TV software update

• The neighbor's remote control worked. It looks crazy: the range of infrared radiation, which transmits signals in most cases, is powerless to pass the wall. The house opposite is pampered through the window frame - the distance is too big. Another thing is if we use radio remote controls - available to some home theaters. Consider the remote control option critically; if you have any doubts, cover the peephole with chocolate foil (chewing gum) and wait for the result.
• The second version, other than software, is controversial. Explained by a power surge. Household appliances do not turn on. Turns on, especially stereo systems! As for the TV, the microcircuit is designed to start generation with a jump in the input voltage (the moment the power button is pressed). However, the module works in standby mode. The TV is waiting for a signal from the remote control. We assume the possibility of being caused by inconsistency of the power supply. Use a surge protector, affectionately called a rat by computer geeks.

Amateurs offer the option of replacing the power supply, but we adhere to the view that the solution is unusable. New TVs turn on. The devices contain a standby power supply. The generator is waiting for a signal. It is provided for starting by the network, the leading edge of the voltage, the surge can cause the effect of spontaneous switching on!

1. If the screen is white/gray/black, solid color.
2. There is no sound, maximum hum from the speakers.

Signs of automatic software update mode. Turn on the TV and the channel starts broadcasting. Picture, sound. People write all sorts of things. The TV turns on by itself for a while, then the image fails. After waiting a few days, it appears. Signs of changes in software.

We see a chance for the following events to develop - the service department is trying to plug the holes, they are ashamed to inform the user, protecting the prestige of the company. Important! Fierce competition between Korean and other Asian companies makes it difficult to sleep at night. Let planet Earth stay awake in parallel, encouraging the manufacturer.

In the fall of 2013, Panasonic planned to stop producing plasma panels. The segment was not profitable. Can you imagine the effect if information leaks out: the manufacturer’s TVs behave inappropriately, causing horror to the owners, interfering with sleep? The flow of clients will instantly subside, flooding the wallets of competitors, a normal company will be afraid. They will politely ask you to set the settings correctly... By the way, the settings! Spontaneous turning on of the TV can be stopped by resetting it to default using the Reset button. Factory settings sometimes save clients from problems. Try, as an option, taking the trouble to save the old ones.

By the new year (2014), LG and Samsung were strictly dividing the segment, delimiting spheres of influence. Companies will hesitate to admit it if the software is crude. Don't forget hackers. Although the word is foreign, the country is full of morons who cause problems for other people, hacking other people's computers out of nothing to do. Finally, it is known abroad: letters on the Internet are read by special services; you have posted a lot of YouTube videos, telling the specifics of the work of the invisible front. It is possible that they are simply trying to spy on the owner of the TV if a webcam is installed. The moral is simple: turn off your home router at night so that no network reckless person gets into the local network (equip the distribution panel with a separate circuit breaker). If the TV is too lazy to update the firmware at night, it will eventually do it during the day, when the surroundings are not so scary and mysterious.

How to Recognize If Your Cat Is About to Kill You

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.

Content

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.

Sleep Timer

Every year, TVs become smarter, and the system for controlling their functionality becomes more complex. Smart TV settings are not initially clear to everyone and require close attention from the user. Therefore, there is a high probability of harming the operation of the device.

The most quickly resolved reason for the TV randomly turning off is the incorrectly set time on the sleep timer. An incorrectly set timer parameter can be easily corrected by resetting using the control panel:

1. Go to the menu.
2. Click on “Settings” (wheel).
3. Select Time and then Sleep Timer.
4. Reset the time or turn off this option altogether.

Video instructions for working with the sleep timer:

Always read the instructions carefully before setting settings other than the factory defaults. You may not complete the installation correctly, which will lead to malfunctions of the device.

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.

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.

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.
