There’s also the energy-saving feature “Auto Power Off after 2 Hours”, which, as the option suggests, powers the TV off after two hours of no user interaction.

From the Time & Timer menu, ensure the time and date are correct. Otherwise, there may be an error when setting the Power On/Off Timer. We advise leaving the date and time to “Set Automatically” on your LG TV.

Benefits of Using Sleep Timer on LG TV

Using the Sleep Timer function on your LG TV has several benefits. Below we’ve discussed some of them.

  • Energy Saving: Leaving your TV on all night wastes electricity, increasing your carbon footprint. Sleep Timer ensures your TV goes on standby after a specified period, saving you money on energy bills and contributing to a greener planet.
  • Extending Lifespan: Continuous use of your LG TV for long periods can decrease its lifespan, especially if you have an OLED model susceptible to burn-ins and image retention issues. The Sleep Timer TV turns off your TV after a set time, extending its lifespan.
  • Improved Sleep Quality: Studies show that watching TV before bed can interfere with your sleep quality, leaving you groggy the next day. You can configure the Sleep Timer to limit your exposure to TV before bedtime, leading to better sleep.
  • Noise reduction: If you live in a small apartment or share a bedroom, leaving the TV on all night can be disruptive. Using the Sleep Timer function, you can reduce the noise level in your environment and allow for a more peaceful sleep for yourself and others.
  • Convenience: Setting up LG’s Sleep Timer is a straightforward process. In fact, it’s a matter of a few button presses on your TV remote. It means you don’t have to worry about getting up to power your TV off or set an external timer.
