My TV switches itself off

My TV switches itself off

There are two main reasons for your TV switching itself off:

1 It has switched off due to your settings (e.g. Sleep Timer is on) or,
2 It has switched off because a connected device has switched off (e.g. you are connected to a PC and the PC has gone to sleep)

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


 If you have checked each of the possible solutions and are still having trouble, your TV may need a service. Please click one of the blue buttons at the bottom of the screen to get in touch. 

Eco Solution

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


You can change the Eco Solution options by going to:

Menu > System > Eco Solution

Sleep Timer

Check to see if you have the Sleep Timer set. 


You can change this option by going to:

Menu > System > Time > Sleep Timer

Standby Mode Upgrade

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. 


The automatic updates can be disabled if required through the MENU on your TV. Using the remote control navigate through the menu using the navigation keys to the following: Settings > Software Upgrade > Standby Mode Upgrade and then set the feature to Off

Note: the above instructions and the image below may differ slightly for your specific TV model.

What is your TV connected to?

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. Connect them one at a time to see if you can isolate which device is causing your TV to switch off.  

Check that the firmware on your TV is up to date

Check that your TV firmware is up-to-date.  


Update your firmware through the TV 


You can do this by pressing either the Menu or Settings button on your remote (depending on your model), then going to: 


Support > Software Update > Update now > Yes  


Update your firmware using a USB stick 


If you are having difficulty updating your firmware automatically or over an internet connection, you can also download the latest update from the Samsung site and then use a USB stick to update your TV. 


To find the latest firmware for your TV on the support page for your model:

1 Enter your model number into the search box at the top of the site
2 Tick the Firmware box in the list at the side, then click on the firmware for your model
