Samsung TV turns off and turns on itself

No equipment is immune from premature failure. Therefore, even if you buy expensive equipment, still keep in mind that there is a possibility of the device breaking down. Of course, TV equipment from Samsung is no exception to this rule.

There are many different symptoms that indicate that the equipment is not working properly. The most common sign of device failure is that the Samsung TV turns off and turns on itself.

What to do in such cases? Of course, first of all you need to find out the reason for the incorrect operation of the equipment. Once you determine what caused the problem with your Samsung TV, you can quickly fix the problem. You can do this either independently or by contacting a service center.

External reasons

After carrying out basic diagnostics, the user will determine why the Samsung TV turns off on its own or, on the contrary, starts up randomly. As a rule, eliminating minor failures does not require special skills, so you can handle it yourself without contacting a service center.

Now we will analyze the most obvious reasons for the incorrect operation of external equipment, and also analyze the optimal ways to solve the problems that have arisen.

It’s clear that you absolutely shouldn’t disassemble the TV right away; first you need to check it for external faults:

breakdown of the remote control;
damage to the power cable;
sleep timer;
failure of the antenna or module for wireless Internet connection.

Now we will consider in as much detail as possible all the reasons listed above due to which TVs turn on automatically.

Incorrect setting

The reason why TVs turn off on their own may be due to incorrect settings. For example, some devices may automatically turn off if the user does not use the remote control for a long time. This is a built-in feature for them. The problem can be solved very simply: in the settings, check whether automatic shutdown is enabled, and, if necessary, disable it.

Repairs with or without warranty

If you bought the equipment recently and it is still under warranty, then use the free services of the service center. If the breakdown occurs after the warranty period has already expired, then have the equipment repaired in a regular workshop.

Choose your technicians carefully so that they have sufficient skills to repair such devices. It is advisable that they have documents confirming their qualifications and a guarantee for their work. Otherwise, if you need, for example, matrix repair, and the craftsmen cannot do it or, even worse, break it completely, you will simply throw money down the drain.

Adverse operating conditions

The operating conditions of the TV cause the TV to automatically turn off. If the TV is located in a room with high temperature, high dust concentration, high humidity or a constant threat of mechanical damage to the heat sink, then it will definitely become faulty. Therefore, if at first the equipment worked normally, and then the TV began to turn off on its own, then try placing it in another place.

Don't forget about regular preventive maintenance of the device. Remove dust from it with paper napkins and immediately wipe off water if it gets on it.

Broken remote control

If the TV turns on and immediately turns off, but does not respond to the remote control, then you need to check its functionality. Inspect the device for mechanical damage, check if the buttons are stuck, change the batteries.

Using your smartphone camera, you can check whether the remote control is firing from the infrared sensor. Point the camera at the sensor so that you can see it on the smartphone screen. Then press several different buttons, if there is no light, then the remote control is broken. The reason is that the battery life has expired or there is mechanical damage.

The program is to blame

Users have registered such a strange malfunction in modern new generation products: a newly purchased LG TV turns on independently at different times. By the way, Samsung or Philips TVs also surprised users by turning on on their own at the most inopportune times.

The reasons for the incorrect behavior of reliable household appliances are different:

factory smart settings;
the user did not disable the software update module, the product was automatically configured according to the new data package received from the Internet;
The product has a program installed
that gives a command - and the TV turns on itself after some time or turns off at the most interesting place in the movie you are watching.

When your TV turns on on its own after hours, it is not necessary to call a technician; try doing the following on your own:

enter the menu and uncheck the box next to the self-shutdown function;
carefully examine recently installed programs, remove updates that are suspicious.

If after this your TV turns on spontaneously, then the problem is elsewhere.

Problem with the socket

If the TV stops working on its own, be sure to inspect the cable, power adapter, and outlet the device is plugged into. Lack of power supply during non-contact causes malfunctions, as a result the TV will turn off, thus going into protection mode.

Proceed as follows:

Check connectors and plugs for mechanical damage.
Are there any fractures or kinks in the power cable?
Look to see if dark spots or charring have appeared on the fork.
Securely secure the socket.

If possible, connect the TV to a different outlet.

Wi-Fi disappears

Problems with a wireless Internet connection can arise not only due to a broken Wi-Fi adapter, but also due to software glitches or incorrectly configured settings. It cannot be ruled out that the router was causing the problem. Try connecting to your home network using other devices, such as a smartphone. If everything works, then the Smart TV LCD TV requires replacing the Wi-Fi module; to do this, contact a service center.

Problems with TV

Troubleshooting television equipment should begin with a complete reboot; perform a complete reset of user settings. Disconnect the device from the mains to briefly relieve the capacitors; they should cool down a little. Wait literally 1-2 minutes, and then turn on the TV again.

The main thing is not to confuse a hardware failure with a software failure. Operational-type problems are resolved by installing the latest service pack. With hardware it is a little more difficult, because you have to disassemble the TV.

If you have updated the operating system, but Smart TV still lives its own life, then you need to dismantle the back panel and look for the cause of the problem with the hardware component of the device. If you do not have the skills to disassemble TVs, then it is better to contact a service center.

What should you consider when disassembling television equipment? First, to remove the back panel, you need to unscrew the screws, for this you will need a screwdriver of the appropriate size. When unscrewing fasteners, remember their location, otherwise you will encounter serious problems during the assembly process.

Secondly, if you replaced a faulty hardware module and now want to check if the TV is working, you should replace the back cover and tighten all the bolts. All this is done for safety reasons.

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.

Dust or moisture has gotten inside

If dust has accumulated in the hardware component, it must be removed using a vacuum cleaner. Mostly, this simple action allows you to solve the problem with periodic spontaneous turning on of the TV device. The thing is that dust conducts electric current, in addition, even a small clot will be enough for static electricity. As a result, a short circuit occurs. The TV switches to protection mode.

Moisture causes corrosion to form on the contacts, causing the signal to be transmitted unevenly. Therefore, if moisture gets inside, you should clean it immediately.

Problems in electrical circuits

If you still have doubts, you can diagnose this type of breakdown yourself:

Turn off the TV and then remove the back panel.
Inspect the condition of the board yourself; for this you will need a magnifying glass or magnifying glass.
If a part is cracked, it needs to be replaced; spare parts can be purchased at the appropriate stores.

Restoring electrical circuits is an extremely serious problem, so it is best to entrust its repair to a specialist.
