My TV switches itself off

My TV switches itself off

If your TV is turning off by itself, there are a number of possible causes and solutions, depending on your TV and setup. The two main reasons for a TV switching itself off are that a connected device has powered off or it is due to your settings. 


If you're having issues turning your TV on, find out the causes and solutions for this issue.

Check the Eco Solution settingsClick to Expand

The Eco Solution function switches the power off if it detects that you are receiving no signal from the current source, for example, if you have switched your set top box to standby mode or if no user operation is received after four hours.

Check the Sleep Timer settingsClick to Expand

A sleep timer can be set so that your TV will switch itself off automatically after a certain amount of time. If your TV is switching itself off you should check to see if a sleep timer has been activated.

Check your connectionsClick to Expand

Your screen may go dark if the source that your TV was connected to turns off. For example, this may happen when you turn off your set top box, or if you have connected your TV to your PC and the PC goes to sleep.  


If you have checked your settings and the TV is still switching off, disconnect your TV from connected devices such as set top boxes, games consoles or PCs. Reconnect them one at a time to determine which device is causing your TV to switch off.  

Check for software updatesClick to Expand

If you are having trouble with your Samsung Smart TV, you should always check to see if there are any software updates available as these may contain a fix for your problem.


The easiest way to update your software is directly through the settings menu on your TV. If your TV isn't connected to the internet or your internet connection isn't stable, you can also update using a USB stick. Find out more about updating with a USB stick.

Standby Mode Upgrade Click to Expand

Some older models can turn themselves on and off if the Standby Mode Upgrade option is enabled in the settings menu.


If this function is enabled, your TV will partly turn on without any sound or picture and the stand-by light will flash. In this mode the TV searches for the latest firmware update via RF broadcast signals and receives the latest update if one is available. 

Please note: this feature is only available on older TVs. On newer TVs software updates are done over the internet
