My Samsung television turns off automatically

Last Update date : Mar 16. 2022

For your convenience, there are many ways for your TV to connect with other devices and automatically turn on or off when needed. However, if your TV is turning off and on continuously, there are one or two simple actions you can take to fix it. The first step is unplugging the TV.

Samsung TV

There are four cases in which your TV either turns itself off or appears to turn itself off. 

  • The customer is using the TV as a monitor and the PC is in sleep mode
  • No signal from Cable or satellite box
  • Sleep timer is set
  • Off timer is set

Please see the below list of possible solutions, but please note that some of the functions below may not apply to all models.

Restart your TV

Turn it off by pressing the Power button on the unit itself or on the remote. Then unplug the TV from the wall outlet or surge protector for 30 seconds, and then plug it back in.

Update the Software

In some cases, a software update can correct the problem. Updates can take up to 30 minutes depending on network speed. 

Your TV will receive software updates to add new features or fix bugs. No matter what TV you have, keeping your software up to date is very important. You can update your TV's software over the internet or using a USB flash drive.

Disable the power on with mobile option

TVs which can connect to SmartThings can be turned on using compatible devices, sometimes automatically. However, if abnormal "power on" signals are sent through the wireless network, they will trigger this function and make the TV turn on. 

If you do not want this function, navigate to Settings > General > Network > Expert Settings > Power On with Mobile, and turn the setting off.

Other Solutions

Check to see if you have a Sleep Timer set. This appears on older models. and can be changed by going to Menu > System > Time > Sleep Timer

Some older models can turn themselves on and off if the Standby Mode Upgrade option in the menu is enabled. If this function is enabled, your TV will partly turn on (there should be no sound or picture) and only the stand-by light will flash. In this mode, the TV searches for the latest firmware update via the RF broadcast signal and receives the latest update if one is present.

You can change this in Settings > Software Upgrade > Standby Mode Upgrade and then set the feature to Off.

Note: Device menus may vary depending on the device model and software version.
