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

My Samsung TV Keeps Turning Off Every 5 SecondsCheck the outlet and power cord sometimes if the problem persists.

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:

  1. Any problems with the power cord should be checked first. In case the cord is damaged, it should be replaced. 
  2. The next step is to determine if the outlet has a power problem. Make sure you try an alternate outlet. 
  3. 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.

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:

  1. Choose Settings from the menu.

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.
