Navigating to the sleep timer in settings
To navigate to the sleep timer in the settings of your Samsung TV, you must first ensure that no other apps are open in the background.

Connecting to the internet or an antenna
To use the sleep timer on your Samsung TV, your device must be connected to the internet or an antenna. This is because the sleep timer function relies on an accurate clock, which can be set up automatically when your TV is connected to the internet or receives broadcast signals.
If you want to manually set up the clock on your Samsung TV, you can do so by following these steps:
- Press the Home button on your TV's remote to open the Smart Hub.
- Use the directional pad on your remote to navigate to Settings.
- Select Time and use the directional buttons to adjust and set the specific time.
Alternatively, you can let your Samsung TV handle the time setting automatically by connecting it to the internet or an antenna. Here's how to do it:
- Using your remote, navigate to and select Menu, then select Settings (All Settings), and then select General (General & Privacy).
- Select System Manager.
- Select Time, and then select Clock.
- Select Clock Mode, and then select Auto to set the time automatically.
Please note that if the Clock setting is greyed out, it is likely because you are in an app on your TV. To resolve this, simply exit the app and change your TV to the TV source, and then try to set the time again.

Using the SmartThings app
If your Samsung remote is lost or broken, you can download the SmartThings app from the Play Store or App Store on your phone and pair it with your TV. Once paired, you can use the app as a remote control to navigate to the TV's Settings and enable the sleep timer.
To do this, first, turn on your Samsung TV. Then, press the Home button and hit the Settings icon. Next, navigate to the Time section and click on Sleep Timer. Finally, choose your desired duration from the available options: 30, 60, 90, 120, or 180 minutes. After selecting the duration, your Samsung TV will automatically turn off after that time.
Note that the sleep timer function only works when the TV is connected to the internet or with an antenna. Additionally, if you are watching TV through an app, the sleep timer option may be greyed out, and you will need to change the TV source or an HDMI source.
You can also use the SmartThings app to create custom sleep routines. For example, you can set up a night routine where one tap turns off the lights, adjusts the thermostat, locks your doors, switches on your security system, and turns on any night lights. Similarly, you can create a morning routine that opens your blinds, turns on your Samsung TV or your alarm, and starts brewing coffee.
