Samsung TV turns off by itself, how to do it

Smart gadgets give you all the flexibility you need in one device. Most Smart devices allow for customization, remote viewing, etc. However, sometimes these devices have problems. These problems can cause your device, in this case, your Samsung TV to turn itself off.

It can be frustrating when your Samsung TV turns itself off and you can’t pinpoint the problem. There are a lot of reasons this could happen. In this article, you find some solutions on why your Samsung TV turns off by itself.

The main reason why your Samsung TV keeps turning off is usually due to problems with the TV settings or an error in connecting with external devices. Let’s try to understand why this happens, beyond the usual set of appropriate solutions.

Samsung smart TVs are sophisticated devices that have the ability to turn off on their own. This is by design in most cases, but can become a problem if the behavior is unwanted by the TV owner. However, there are ways to identify if this is something that should happen or if there is a malfunction that needs to be fixed.

The most likely reason the TV turns itself off is that it has a timer set to a predefined duration and turns the TV off after a certain time. Other possible problems are that you may have power problems, problems with the connected device, dead batteries on the remote control, or hardware problems.

When the first symptoms appear, the user must find and eliminate the malfunction. The first reason is to make sure it’s not dangerous enough so that it can’t damage your TV later. Most likely, the cause of the problem is trivial, and it will be possible to do without repair. Here we have listed the 7 most common reasons why the TV turns off by itself in more than 95% of cases.

The main reasons why the TV turns off by itself:

1. The TV timer has been set to Off
2. Power problems
3. Dust and humidity
4. Malfunction of electronic components
5. Hardware problems (main board).
6. Dead batteries in the remote control cause the TV to turn off
7. The power button on the remote control can be locked

While there can be many reasons why your TV turns off by itself, we will look at the most common reasons that have been confirmed in over 95% of cases. As the TV is used by multiple family members, it may happen that someone has set the TV timer to turn off after a certain time. Another reason may be that the remote’s power button is stuck. Therefore, let’s get started and see the main reasons for this problem.

1. Timer TV

Maybe someone in your house has set a TV timer to turn off the TV at a certain time. In many cases, this is one of the main reasons why the TV turns off. It can be configured to turn off the TV after a certain time, but in order for it to be idle, it is best to turn it off:

1. They turn on the TV.
2. Press the “MENU” button on the remote control of the TV and enter the “SETUP” menu.
3. Press the “ENTER” button on the remote control and enter the “TIME” menu.
4. Use the arrow buttons on the remote control to select “TIMER” and press the “ENTER” button, then the “TIMER” screen will appear.
5. Use the remote control and deactivate the “TIMER” mode.
6. Press the “EXIT” button on the remote control to exit the settings.

If your TV has a sleep timer, follow the same steps above, but go to the Sleep Timer tab instead.

2. HDMI peripherals and software recovery

If an amplifier and an HDMI player are connected to the TV, the ARC may also be receiving signals which the unit can interpret as “On”. In this case, it is recommended that you disconnect all HDMI cables and check if there is a possibility of failure.

Whether the user is using a modern LED TV with Internet access or an older LCD TV, the first thing to do to solve the problem is restart the device unplug it from the power source, then turn it back on. If your TV has a variety of software, it’s worth restoring factory settings and updating the software.

If the above TV turns off again, try to reset the “MASTER RESET “Or the” FACTORY RESET “. The functions can be found in the basic settings of the TV menu.

Furthermore, if the user has a Smart TV connected to the Internet via WIFI, it is recommended to update the system BIOS or TV software. If a system update doesn’t fix your TV, it may have a serious problem with major components.

3. Power problems

The TV may malfunction during operation, turning itself off, due to problems in the power system. So, to better understand this problem, let’s dive into it. The main types of problems with the power supply of the TV:

1. Permanent false contact in the socket. Make sure that the plug and socket are in good technical condition and connected correctly.
2. The power cord is in bad condition. Check for false contacts or breaks and cuts.
3. Check that the power cord is properly connected to the back of the TV
4. A power surge or a faulty power supply. Usually, the most common problem that allows you to turn off Smart TV. Power surges or spikes can cause the TV to turn on, especially if the power capacitors are old or damaged.
5. Another somewhat trivial mistake is that the plug that the device is connected to has too many cables connected to other devices with 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.
6. Damaged HDMI cable, Ethernet cable, or antenna cable. They check the condition of the cables, especially the plugs and the insulation of the wires, perhaps the problem is in the electricity and not in the fault of the receiver.

4. Dust and humidity

Due to the contamination of the electronic board with dust, a short circuit of the current carrying conductors can often occur with overheating of the semiconductor components: micro cards, triodes or diodes. In this case, the TV is turned off by the overheating protection. Therefore, from time to time it is necessary to clean the device from the accumulation of dirt.

Water is equally dangerous for electrical equipment: it oxidizes contacts, creating the possibility of short circuits. The oxidized contacts must be cleaned of deposits and sometimes re-welded or tinned with an electric soldering iron.

The traces of the electronic boards corroded by humidity are repaired orapplication of drops welding or by installing a jumper of fine wire.

Before doing any work on the TV, remember to safety and fully de-energize the device. You also need to be careful when disassembling: do not tear or confuse the connectors to connect the circuits and wiring.

To eliminate the problem of periodic shutdowns for dust it is necessary:

• Unscrew the mounting screws;
• open the container;
• using a small brush or a vacuum cleaner clean the dust deposits.

After these operations, the TV normally restores its functionality.

5. Severe damage

In case the above procedures have not solved the problem, the source of the TV defect it is much more serious than it might seem at first glance. The best solution, in this case, is to contact the service department for professional support. However, if the owner of such a device is familiar with radio engineering and has practical skillsknows how to work with a tester and a soldering iron, you can try to find the root cause of the malfunction yourself. The main operations to test the operability of functional TV elements:

1. Disconnect the device from the network.
2. Remove the rear panel.
3. Examine the capacitors of the power supply unit. Over time, electrolytes can lose function by drying out or swelling. Sometimes the capacitor is able to “flow”, which activates the oxidation of the traces on the electronic board. After identifying a damaged capacitor, it must be replaced.
4. Prefabricated units are carefully inspected. For what, it is necessary to provide high-quality lighting. When the TV is on, ring cracks can form in the card tracks, caused by constant heating. Over time, various welding defects can also be detected. Therefore, anything that doesn’t inspire confidence and seems problematic needs to be soldered.

Expert advice

So that the user does not have to carry out the restoration of an expensive device on his own or overpay to the service centers, it is better to follow the recommendations of specialists in the operation of modern TVs:

1. It is not allowed to install the TV on the windowsill, next to the aquarium and in other areas where water can reach the electronic board.
2. It is necessary to periodically clean the room. This will reduce the accumulation of dust and dirt on important TV cards.
3. It is not allowed to leave the TV connected to the network while it is not in use.
4. A voltage stabilizer is installed to protect all electrical appliances, preferably at the entrance of electricity to the apartment.
5. During operation, you will need to make sure that the force of pressing the buttons on the control panel is reasonable – it is not necessary to hold them down with some force.

There are various reasons why the Samsung TV turns off by itself. As you can see, in most cases, it’s not that hard troubleshoot by turning off the TV yourself. Also, the methods for solving such problems on Samsung, Vizio, Mitsubishi, LG, SONY, Panasonic, HiSense, Hitachi, Element, Magnavox, Sanyo and all other TV models are the same.

Samsung TV does not turn on, what to do?

The main fact of why the TVs themselves turn off is the incorrectly set options. For example, some structures have the ability to switch off automatically if the user has not used the remote control for a long time. This error can be easily eliminated via the settings menu. If the fault is hardware and the owner does not have sufficient experience, it is better to invite a specialist for repair.
