LG TV Turns On By Itself

Table of Contents

If your LG TV turns on by itself, it could be due to the button that got stuck on the remote or your TV isn’t getting a solid power connection. Another major reason for your LG TV turning on could be that you have left the HDMI-CEC on. You just need to go to Settings => All Settings => General => SIMPlink(HDMI-CEC) => OFF. And this would do the job.


HDMI Consumer Electronics Control (HDMI-CEC) is a feature in smart TV’s that allows devices connected to your TV through HDMI ports to communicate back and forth with your TV. What it basically does it give other HDMI control devices some partial control on your smart TV which can let them to switch on or off your TV.

For example, when you turn on your PlayStation, CEC can automatically turn your TV on and switch it to the correct input without you having to grab your other remote.

By default, it makes your life easier by switching on your TV when you turn these devices on. If your LG TV is turning on by itself you should definitely look into this.

  • Press the Gear icon on your remote
  • Then go to Settings => All Settings => General => SIMPLINK (HDMI-CEC) to OFF

If it does solve the problem but you still need to use the HDMI-CEC feature, you need to start disabling this feature one by one on other devices to check which one is sending the random signal.

IF turning off HDMI-CEC doesn’t solve the problem, then you might need to proceed to the next steps to check if it solves the issue.

Disable Eco mode

Vizio TVs also come equipped with something called Eco mode. This Eco mode is sometimes known to have issues with it and makes sense to turn it off if your TV keeps on turning on.

To disable Eco mode on your Vizio TV, you need to press Settings on your Vizio TV remote.

Next go to => General => Eco Mode

Set it to OFF.

Disable Timer Settings

All smart TV’s comes with timer settings that can help you to switch on or switch off your TV. LG TV is no exception and that could be the culprit for this problem.

All you need to do is to disable the timer setting on your LG TV.

Steps to disable Timer settings:

  • Turn your TV on
  • Click on Gear icon on your remote
  • Select All Settings
  • Select General
  • Switch all timers to OFF

Make sure you disable all other timers such as “Power On” and “Power Off” as well to avoid this problem in the future.

Unplug LG TV to Power-cycle

This small thing solves most of the issues. While everybody does skip this step, all you need to power cycle your TV. Here’s how.

Simply unplug the LG TV plug from the socket and wait for full 60 seconds to fully power cycle your TV.

While you have unplugged the TV, press the power button on your LG TV for 30 seconds. Just make sure that you hold the power button of your TV and not your remote. What will it do? Well, it will drain out excess power left in the TV which could be causing your LG TV to turn on.

Once you plug in the TV after 60 seconds, that should resolve the issue of TV turning on by itself. If it doesn’t solve the problem that means we need to do a little more troubleshooting.


Issues With Loose Power Connection

An erratic power supply to your TV could be the reason for turning it on by itself. All you need to do is to disconnect it first and then connect it again. Make sure that it is properly connected.

This simple fix is reported to have fixed these kinds of issues in many old LG TVs.

If you see some problem with the cord or the plug, it is better to go for the replacement before going ahead with other steps. All your power cords and cables need to be in good condition and firmly connected.


Change Batteries in TV Remote

A TV remote working on a low battery could be sending erratic signals to your TV. First of all, make sure you take out both the batteries from your remote and hold down the power button on your remote for full 30 seconds, nothing less.

After 30 seconds, put the batteries back into the remote and turn on the TV. You could also try replacing the batteries to be double sure. If you run into the same problem after a few weeks, it means you might need to update the firmware or contact support for a permanent solution.

Disconnect From Wifi

Our smart TV’s connect to numerous other hardware devices like smartphones, Alexa, Google Home at home. Ironically, these devices could be sending signals to turn on your TV by accident.

If your TV has a built-in casting ability, that could be even turning on your TV while you watch a video on Youtube.

A simple for this problem is to disconnect it from Wi-Fi for a few days and then wait for a few days to see if the problem persists. If it doesn’t then get it back to Wifi and keep on disconnecting other hardware apps one by one from Wifi to see which one is causing the TV to turn on by itself.

Factory Reset LG TV to Default Settings

Factory reset is yet another option to get rid of this commonly occurring problem. What it basically does is to put your TV back in the install mode. This will wipe out all the settings and changes that you have done over the period.

Here is what you need to do:

  • Turn your TV on
  • Click on Gear icon on your remote.
  • Select All Settings.
  • Select General.
  • Select “Reset to Initial Settings

This will turn off your TV and then turn it on and will display the initial configuration screen.

Once you are on this screen, it means all the settings, configurations and downloaded apps have been wiped out and you need to do the same things again.

Note: Do not do a factory reset if you do not want to go through the same process again. Or do it as your last step once you are done with all other steps.

TV Doesn’t Have Latest Firmware

You can potentially run into a lot of problems if your TV software isn’t up-to-date. Check if your LG TV software is up-to-date. If automatic updates are not on by default, you may need to update it manually.

Do This to check automatic updates:

  • Turn your TV on
  • Click on Gear icon on your remote.
  • Select Settings => All Settings.
  • Select “About.
  • Click “System Update.” (Also make sure that automatic updates are checked on)

Once you update the TV with the latest firmware, the issue should not arise anymore. If it does, then it could be some other problem with your TV

You may also check the current firmware version under the “About”

LG TV support and Warranty

If none of these measures work, you should contact LG’s customer support system. This is your last and the only step to fix your TV from this problem.

Customer support’s phone number is 850.999.4934 / 800.243.0000.

The cost of the service again depends on the diagnosis. If some part needs replacement, then the cost is definitely going to be higher.

Before calling the engineer, you need to check if your TV Is under warranty. Unfortunately, LG offers only a 1-year warranty on all its TV products line.
