What causes My Samsung TV Keeps Turning Off Every 5 Seconds?
There are a few reasons why Samsung TVs can automatically shut down after a few seconds.
It would be nice if we could begin by making some easy fixes and then move on to more complex ones that require some disassembly.
Power supply problems
Since it can’t maintain itself without power, a Samsung TV will automatically shut off after five seconds if there is no power.
If that is the problem, you can take the following steps:
- Any problems with the power cord should be checked first. In case the cord is damaged, it should be replaced.
- The next step is to determine if the outlet has a power problem. Make sure you try an alternate outlet.
- Attempt to plug another electronic device into the outlet if the one you are trying to use doesn’t work.
There is also a possibility that you may be using a surge protector or extension cord that is causing the issue. We recommend making sure that none of these are the issue.
The TV should be plugged directly into the wall and the surge protector and extension cable should be removed.
Anynet+ (HDMI-CEC) is ON
Connected devices become more cooperative with HDMI Consumer Electronics Control (HDMI-CEC).
You can access your TV from your HDMI-connected devices and your TV from your devices with an HDMI adapter.
A television that supports HDMI-CEC, for instance, can control a DVD player. Whenever the DVD player is on, the TV’s input can be changed to HDMI.
Some HDMI devices are configured to automatically turn off the TV when they are turned off.
If your TV is automatically turning off, you should check Samsung’s Anynet+ feature (also known as HDMI-CEC).
To do this, press the HOME button on your remote and navigate to SETTINGS > GENERAL > EXTERNAL DEVICE MANAGER > ANYNET+ > OFF.
Using your TV remote to control any other device will no longer be possible.
You can check if your problem is resolved by disabling Anynet+. Samsung TVs that do not turn off every 5 seconds may be affected by a variety of factors.

The System Is Corrupted
You might also see your Samsung TV shutting off every five seconds in addition to its corrupted system. When smart TVs are used for downloading files or browsing the Internet, they can also become infected with viruses.
It is possible for a virus to affect your TV’s internal components. This will cause the TV to shut down every five seconds.
You can find out if your TV’s system is corrupt by following these steps:
- Using your remote control, you can access the Settings menu.
- Select the General option from the menu.
- Go to System Manager.
- The next step is to choose Smart Security.
- The Scan option is available. Click it to begin.
- Your TV will perform an automatic virus scan.
You can reset your TV by turning it on and off again if it turns itself off before scanning. This will erase any viruses on the Samsung TV.
Here’s what you need to do:
- Your TV should be unplugged and turned off.
- The TV power button should be held for two minutes (don’t use the remote or the TV power button!).
- You should now be able to connect the TV to an outlet.
- If you turn it on, you’ll be able to determine whether the issue persists.
In addition to performing a hard reset, you can also restart your TV. The factory setting reset of your TV means all your settings will be lost.
Here are the steps:
- In the Settings menu, you can find your TV’s settings.
- Choose Reset from the menu. Select your PIN to reset the TV. If you hadn’t changed your PIN when you bought the device, you can use its default PIN: 0000.
- Selecting OK will cause your TV to automatically restart.
Some models may have a Reset option in a different location. In this case, go to Support and select Self Diagnosis if you cannot find it. From the menu, select Reset.

Overheating Samsung TV
Having no proper airflow and ventilation can cause a television to overheat and malfunction.
If that’s the case, you can follow these steps:
- Turn off the television.
- Dust should be wiped off the back of the TV using a microfiber cloth.
- A blockage can prevent ventilation, which can lead to overheating. Make sure there are no obstructions to the vents.
Air conditioners or better ventilation are required to keep a room cool.
Samsung TVs need an update
A Smart TV must constantly be updated in order to ensure that it works properly. TVs that are not regularly updated may malfunction.
You need to update the firmware on your TV to the latest version.
Following are the steps to be taken:
- Choose Settings from the menu.
- Support is the option to select.
- Update the software by clicking on it.
- This option allows you to update your software.
You will receive automatic updates on your TV. It may take a few minutes for your TV to notify you that it has completed.
Samsung TV has a power short
When you remove the back panel of your Samsung TV, you will see a cable going from the main board to the power supply board.
It is possible for a short to occur due to this cable between these two boards. Your TV will start and stop as a result.
This cable connection has four pins on the top, which can be removed easily to eliminate the short.
By pushing in and prying up, you can remove the cable. In the event that this signal stops shorting out, the main board of your TV will reboot.
The Motherboard Is Failing
Your TV may also be turning off every 5 seconds because of a faulty motherboard.
The motherboard assists all electrical connections between the various parts of the TV by acting as a communication hub. A failure of the motherboard will prevent the TV from operating.
A failing capacitor on the motherboard is most often to blame for this issue. Lighting storms commonly cause electrical surges that cause capacitors to fail.
The motherboard should be serviced professionally or a new one should be installed if needed.
You may be able to see swollen capacitors on your TV’s motherboard if you lift off the back panel.
If you think you have found the culprit(s), buy new ones and replace the bad ones.
