If your Samsung TV is turning On and Off erratically or for no apparent reason, there are a couple of things to check. Your TV will have Energy Saving functions built in to ensure the TV doesn't use up too much power. You can adjust the energy saving functions in the TV menu.

Check the energy saving settings:

On newer Samsung TVs you'll be able to adjust the Energy Saving Mode and the Auto Power Off mode by following the path below:

1 Press the Home button on your remote control to bring up the Smart Hub/Eden Menu at the bottom of your screen and then select Settings .

2 In the Settings menu on the left hand-side, scroll down to the General tab and select Eco Solution from the middle list.

3 Once you are on the Eco Solution menu, scroll down and turn off Energy Saving Mode and Auto Power Off .

On older Samsung TVs you'll find options to change the No Signal Power off mode as well as the Auto Power Off mode by selecting the options below:

1 Press the Home button on your remote control to bring up the menu, scroll down to the System tab on the left-hand side and then select Eco Solution from the middle menu.

2 Once you are on the Eco Solution menu, you will find Energy Saving and Auto Power Off to make adjustments.

Please note: If the Auto Power Off option is set to Off, the TV will stay on even if no operations are performed on the TV. This will increase the energy usage of your TV significantly.

2018 QLED Models:

If you use the SmartThings app with your 2018 QLED TV, there is one more thing that could be causing your TV to turn off. An option called Allow Phone Presence Detection is available in the Settings of the SmartThings app that will turn your TV off when your connected phone is not physically close to the TV.

Further Steps:

If the Auto Power off and other energy saving settings are set how you would like them and you're still having trouble with your TV powering off unexpectedly, there are only a few more options available:

1 Unplug the TV from power

Unplug the TV from the power socket or surge protector. Leave the TV for a few minutes, and then plug it back in.

2 Try a Software Update

If you can keep the TV on for longer than 30 minutes, it may be worth trying to update the firmware of the TV. See the step by step guide on Updating the Firmware of a Samsung TV. Be mindful that if the TV loses power during an update it could damage the TV.

3 Reset the TV

See the step by step guide at How to Reset a Samsung TV.
