LG TV Turns On Itself? – Multiple Methods To Fix This Issue

Sadly, LG TVs have been known to turn on themselves for an excessive period of time. Several problems have been identified as causing this, each with distinct degrees of severity. There are many people, however, who wonder why the LG TV turns on itself, and we’ll explain why.

Are there any reasons why an LG TV turns on by itself?

It is extremely feasible that if your LG TV turns on by itself, it is due to the fact that you have Simplink (HDMI-CEC) enabled on your TV. Moreover, when HDMI devices (such as your DVD player) are turned on, your TV is automatically turned on as well. However, HDMI-CEC can be turned off by going to HOME > SETTINGS > ALL SETTINGS > GENERAL > SIMPLINK (HDMI-CEC) > OFF. There is a decent likelihood that this will fix your LG TV that turns on by itself problem!


Make sure your TV is not using Simplink (HDMI-CEC).

This HDMI feature allows your connected devices to work better together with HDMI Consumer Electronics Control (HDMI-CEC).

In this way, your HDMI-connected devices have limited control over your TV.

HDMI-CEC allows you to control a DVD player from your TV with your remote control, for example. Additionally, when your DVD player is turned on, your TV’s input could be changed to HDMI.

Since your LG TV turns on by itself, LG calls this feature Simplink (also referred to as HDMI-CEC).

  1. It is possible to access the Settings icon at the top right by pushing the HOME button on the remote.
  2. Select SIMPLINK (HDMI-CEC) from the All Settings icon > General.

  4. The Auto Power Sync settings of the device have to be set to the OFF position.

I would suggest that you try to figure out if disabling Simplink resolves your issue. In addition, there are a wide range of other likely motives or reasons why your LG TV is turns on by itself.

The HOME button on your LG TV can be used to turn off all timers by selecting Settings > All Settings > General > Timers from the main menu.
