The HDMI-CEC function in LG is referred to as Simplink. Meanwhile, CEC is the acronym used for Consumer Electronics Control. This feature lets users use the LG remote to control other devices, such as a Blu-Ray player or soundbar. So, if you have a TV remote, you can increase or decrease the soundbar volume with the remote.

This feature is helpful in many cases. But sometimes, it sends signals to turn the TV on or off. The soundbar might have an auto shut-down feature to turn your TV on. So, in order to turn off your LG Simplink HDMI CEC settings, follow this method step-by-step.

  • Navigate the Gear icon on your remote control and press it.
  • Go to All Settings. Now click on Connection.
  • Choose SIMPLINK (HDMI-CEC) and then go to Simplink Settings LG TV.
  • Now disable SIMPLINK configuration. Most often, the problem is resolved by stopping this feature.

It’s not a permanent solution, but you should try unplugging the HDMI device and then wait a day or two to analyze if the problem persists. Make sure to test one HDMI device at a time.

Power Cycle TV


It can be considered one of the quickest and most effective methods to fix the issue of an LG TV that turns on by itself. Many users have tried this method and eliminated this problem. So here’s how you can power cycle your LG smart TV.

  • Unplug the LG TV from the power source. If possible, ensure it’s unplugged for a minute or more.
  • While waiting, hold the power button on your TV for 30 minutes. You can skip this step if your TV does not have a power button.
  • Now plug the TV back into a power outlet. Now, turn it on.
  • After the power cycle, also known as the soft reset, is finished, turn off your LG TV. It will no longer turn on by itself.

Check and Disable the Wake-up Timer


Wake-up times are great for turning on your TV whenever needed. But if you accidentally change it to ON, your TV will turn on itself. That’s why you should check the TV’s settings and check if this timer is turned on. If it’s on, then disable it.

The steps for disabling may vary for different TV models, but generally, this is the method you should follow.

  • Go to the Settings and then choose All Settings.
  • Click on General and then Time.
  • Scroll down and tap on Timers.
  • Check if the timer is on. If it’s on, then turn the timer off.
  • Choose off for all timers, i.e., Off Time, On Time, Sleep Timer.

Check Power Source & Cables

If your power supply is faulty or there’s a power surge, your TV might turn on by itself. That’s why you should take a closer look at each aspect. Check these, and if there’s any issue, fix it accordingly.

  • Check the power cable: Look closely to see if it is fraying or damaged. If it malfunctions, replace it immediately.
  • Inspect all loose cables: Sometimes, the issue is just a loose cable. So ensure all the cables are firmly plugged in.
  • Analyze power outlet: Plug another device, such as a juicer or charger, into the power outlet and check if it’s working properly.
  • Surge protector: If you use a surge protector, unplug the TV cord and directly connect it to the wall outlet. This will test whether your surge protector or extension cord is malfunctioning.

Disable Eco Mode 


With Eco Mode, you can save power while using the LG TV. It also has the ability to turn off your TV automatically. There might be a connection with this feature powering on the TV by itself, which is also included in the list of fixes. To turn off Eco Mode, here’s what you should do.

  • Navigate the Home key on your LG TV remote and press it
  • Click Settings and then choose General
  • Choose Additional Settings. Now, choose Eco Mode. 
  • After that, click on Turn Off Eco Mode and Auto Power Off

After disabling this feature, you might notice that your LG TV will stop turning on itself

Analyze Your Remote Control

Sometimes, the remote control’s power button is pressed or faulty, and the TV keeps turning on by itself. To ensure the buttons start working properly, you should clean the remote. To do this, follow these steps.

  • Check the battery compartment. Now, remove the batteries from the remote control.
  • Open the remote. Find the opening that joins the two halves of the remote.
  • Now, get a microfiber cloth and put some rubbing alcohol on it. You can also use a Q-tip to wipe your remote.
  • Now, air-dry your remote. Put all the things together to join your remote.

Remove The Batteries 

Remove the batteries from your remote control to ensure that the issue is caused by the remote. Now, notice closely if your TV still turns on by itself. Replace the old batteries in the remote with new ones. When the remote’s battery is low, it can send random signals to the LG TV, which can cause the TV to turn on by itself.

Disable Your Phone’s Bluetooth 

If you’ve granted access to your LG TV to any of the apps on your smartphone, this can also cause this issue. The app may be communicating or sending signals to your TV. A simple way to fix this error is to turn off the Bluetooth Settings on your phone. By doing this, you’ll be able to identify if the issue is persisting because of Bluetooth settings.

Disconnect From WiFi

Often, users connect their LG TVs to Amazon Echo or Alexa devices. So, there’s a possibility your TV might turn on by itself because of the voice commands on these devices. That’s why you should disconnect the Wi-Fi connection from LG TV. It’ll stop the involvement of any app or third-party device that’s turning on the TV.

Do Factory Reset

If you’ve tried all the methods mentioned above but none is effective, you should perform a factory reset. This will erase all the customizations and bugs causing this problem.

Here’s how you can do it.

  • Go to the Settings menu. Choose All Settings.
  • Now click on Support. Scroll down to select General.
  • Now navigate to find Reset to default settings.
  • Click on Confirm. Then, enter the password.
  • The LG TV will shut down once resetting is finished.
