1. Possible Conflicts Concerning Power

Checking for any kind of external power difficulties that might be present is the first thing we recommend you do if you’re having power problems. Examine the connection to the TV itself, as well as the power cable and the socket into which the cord is plugged.

It’s possible that the problem is as simple as the plug not being pushed in completely all the way. If not enough power is being supplied to the gadget, the television won’t be able to remain on. Because of this, the television will now switch off by itself every five seconds.

Fraying or breakage at the cable’s ends are potentially more serious issues that could arise. Electrical tape is a common solution for problems of this nature; nevertheless, it is possible that the TV will need to be replaced in some cases.

A power problem could also occur if the television is plugged into an extension cord, a surge protector, or another device of this kind. If you want to test if the issue goes away on its own, try plugging the device straight into the wall.

Having said that, it is of equal significance to check the functionality of the electrical outlet into which you have plugged the television. In order to determine whether or not the outlet is working properly, a simple appliance like a lamp should be plugged into it. If the problem isn’t with the outlet, then it could be the TV itself that’s broken.

2. The television is too hot

The fact that your Samsung TV turns off by itself without any prompting is likely due to the fact that the TV itself is getting too hot. If it does not have adequate airflow, a television will overheat. When anything like this occurs, it might turn off by itself to prevent further harm to the components on the inside.

To begin, disconnect the television set from its power supply so that it can rest and cool down. In an ideal situation, you should wait at least a minute and a half before turning the TV back on. Dust the television thoroughly, and check to see that nothing is obstructing the air vents on the back of the television. After that, reconnect the television and check to see if it is functioning properly.

If the issue seems to have been fixed, but it continues to occur, this could be an indication that there is a more significant problem with the TV’s internal components. If you believe that your TV has a problem with frequent overheating, you should get in touch with assistance as soon as possible. This type of problem is typically covered by the manufacturer’s warranty.

3. Outdated Computer Programs

It is possible that the problem is being caused by out-of-date software on your smart TV, however this isn’t a very likely possibility. If this is the case, then all that needs to be done is an update to the software that is already installed.

It is essential, however, that you do not turn off your TV while the update is being applied, since this could compromise the integrity of the process. It’s possible that doing so will wreck your TV. To perform an update, navigate to Settings > Support > Update Software and then choose the option that offers the most recent available update.

If installing the most recent version of the software does not cure the problem, try the additional solutions that are given before getting in touch with customer service.

4. Anynet+ (HDMI-CEC) is ON

HDMI Consumer Electronics Control, often known as HDMI-CEC, is a feature of HDMI that enables your connected devices to collaborate more effectively with one another.

It gives the devices connected to your TV through HDMI some control over the TV, and it offers the TV some control over the devices attached to it.

Using HDMI-CEC as an illustration, you may use the remote control for your television to operate your DVD player. It’s also possible that your DVD player, when turned on, may immediately switch the input on your TV to HDMI.

When an HDMI device is turned off, the TV will sometimes immediately power down as a result, as this is a default setting for some HDMI devices.

This function is known as Anynet+ by Samsung and is also referred to as HDMI-CEC. Since your TV is going off by itself, you should investigate this because of it.

To turn off ANYNET+, press the HOME button on your remote control, and then navigate to SETTINGS > GENERAL > EXTERNAL DEVICE MANAGER > OFF.

Remember that you will no longer be able to use the remote control that came with your TV to operate any other electronic devices.

Wait to see whether turning off Anynet+ resolves your problem before continuing. In the event that it doesn’t, there are a number of additional possibilities that account for the fact that your Samsung TV turns off every 5 seconds.

5. The System Is Infected with Corrupt files

It’s possible that your Samsung TV‘s system has become corrupted, which would explain why it turns off every 5 seconds. Every time you download a file or use it to navigate the Internet, your smart TV runs the risk of getting a virus, just like your computer does.

It’s possible that a virus is wreaking havoc with the internal mechanism of your TV. Because of this, it will switch off by itself after five seconds have passed.

Here is how you may determine whether or not the system on your TV has been compromised:

  1. You may access the Settings menu by using your remote control.
  2. After entering the menu, go to the General section.
  3. After that, select the System Manager menu item.
  4. Now, select Smart Security from the menu.
  5. You will notice an option that says Scan. Make your choice.
  6. Your TV will do an intelligent scan to look for viruses when it next turns on.

In the event that the TV turns off before the scan is completed, you might attempt performing a power reset. It will remove the virus from your Samsung TV after it completes the reboot.

The following is what you are need to do:

  1. You need to unplug and turn off your television.
  2. Make sure you’re holding down the power button on the actual television and not the one on the remote for the full two minutes (this is very important).
  3. Now you need to connect the TV to the power source.
  4. Try turning it back on and see if the issue still occurs.

You also have the option of doing a hard reset on your TV in the event that it repeatedly powers off by itself. Because using this approach restores your TV to its factory default settings, you will lose all information and configurations that you had previously saved.

This is the procedure to follow:

  1. Bring up the menu for the Settings on your TV.
  2. Choose the option that says “Reset.” You will be prompted to enter your PIN on the TV. You could attempt the default PIN, which is 0000, if you haven’t already changed it since you got the device.
  3. If you select OK, your TV will restart by itself after you confirm the action.

Please take note that the Reset option may be located in a different menu on some models. You might try heading to Support and selecting Self Diagnosis if you are having trouble finding what you are looking for. The option to reset ought to be there.

6. Sleep Timer Settings

We are unable to rule out the chance that this setting is turned on because incorrect settings are one of the most common causes that can cause your Samsung TV to continually shutting off. The Sleep Timer function of your TV is responsible for turning it off at the specified interval.

It’s possible that the Samsung TV was turned on by you or by someone else who uses it. The problem can also be easily fixed because all of you need to do is turn it off. Carry out the following steps:

  1. Go to the Settings menu.
  2. Go to the General menu.
  3. To access the System Manager, click here.
  4. Choose Your Time
  5. Select the “Sleep Timer” button.
  6. Choose the Off option.

7. A Defective Voltage Stabilizer

A surge protector is a piece of equipment that can shield your electrical gadgets from damage caused by sudden spikes in voltage (caused by power outages from lightning or storms). If your Samsung TV is connected to a surge protector and the protector fails, the TV may be going off randomly because the surge protector is causing interference with the signal being sent to it from the TV.

In order to determine whether or not there is a problem, you can remove the surge protector from the circuit and connect the power cord to the television directly to the wall socket. If your television does not turn off by itself when it should, you will need to either replace the surge protector or repair it (if possible).

8. Connection Error

As was just discussed, this is one of the potential and likely reasons why your Samsung TV can keep going off unexpectedly. Nonetheless, this rationale might be triggered by a variety of circumstances, including the following:

If your Samsung TV is connected to other devices, such as game consoles, and those other devices turn off unexpectedly (because of a shaky connection), it is possible that your TV will also turn off.

Before re-connecting their power wires and turning them back on, you need to make sure that they are properly connected by first unplugging them and then turning them off completely.

If you are using an HDMI cable that has not been certified, there is a possibility that a connecting fault will cause your television screen to go black. Change to an HDMI cable that has been validated by the manufacturer if this continues to cause your Samsung TV to turn off unexpectedly.

Power cycling, often known as continuously turning off and then turning on an appliance like a TV, might be an indication that the equipment has been harmed. It’s also possible that an old version of the TV’s software is to blame for this issue.
