Chromecast is a streaming media adapter that enables users to watch videos and listen to music online on their televisions. It consists of a dongle plugged into the TV’s HDMI port and a cable connecting to its USB port to provide power.

Turn off TV with Chromecast from time to time. Various scenarios can apply, including moving, upgrading your TV or Chromecast, or being out of town.

Check out this article to learn how to turn off your TV with a Google Chromecast.

Can I Turn Off My TV With A Chromecast?

If you wish to turn off your TV with Chromecast, please enable HDMI-CEC on your TV and connect your Chromecast to your Google Home. After that, you can turn off the TV using voice commands.

We are entering a new era of convenience with the ability to control your television with your voice or smartphone.

Finding your lost remote control no longer requires digging through sofa cushions or bed sheets.

Before we dive into the fundamentals of switching off the TV using Chromecast, let’s go over everything you need to get started.

Considering that you already have a smartphone or tablet, we presume you can connect to a Wi-Fi network.

What Do I Need To Turn Off My TV With Chromecast?

If you want to turn off your TV using a Chromecast, you need the following:

  • A TV with HDMI-CEC.
  • Google Chromecast.
  • Google Home app.
  • Google smart speaker.


To begin with, you should check whether your TV supports HDMI-CEC. HDMI-CEC (Consumer Electronics Control) is a feature of the HDMI standard that allows connected devices to communicate with each other.

Most TVs that support HDMI have this feature built-in.

HDMI cable

TV manufacturers believe HDMI-CEC is too academic and unappealing to be used in their products. Due to this, the name of this functionality has been rebranded to something more marketing-friendly.

Below is a list of the most popular TV brands and their HDMI-CEC names. This will help you determine whether a certain TV has this capability:

  • LG – Simulink.
  • Emerson – Fun-Link.
  • Hitachi – HDMI-CEC.
  • AOC – E-Link.
  • Onkyo – RIHD.
  • Insignia – INLink.
  • Pioneer – Kuro Link.
  • Loewe: Digital Link or Digital Link Plus
  • ITT – T-Link.
  • Philips – EasyLink.
  • Panasonic – VIERA Link or EZ-Sync.
  • Magnavox – FunLink.
  • Mitsubishi – NetCommand.
  • Runco International – Runco Link.
  • Samsung – Anynet+.
  • Sharp – Aquos Link.
  • Vizio – CEC.
  • Sony – BRAVIA Link, BRAVIA Sync, or Control for HDMI.
  • Toshiba – Regza Link or CE-Link.

Google Chromecast

As soon as you determine whether your television is compatible with HDMI-CEC, you must install and configure your Google Chromecast. This is not something to worry about. The process will not be difficult at all.

Different versions of Google Chromecast

The HDMI end of your Chromecast gadget plugs into a TV port, while the other end plugs into a wall outlet.

As soon as you’re connected, you’ll be able to use your smartphone as a distant control for your TV, allowing you to stream Netflix and YouTube content.

I recommend using the HDMI extender that comes with Chromecast because it will save you a lot of space behind the TV.

The Chromecast is available in a variety of versions, including the following:

  • Chromecast (1st generation).
  • Chromecast (2nd generation).
  • Chromecast (Ultra) – Current generation.
  • Chromecast (3rd generation) – Current generation.

While Google has launched several Chromecast devices, you will still be able to turn your television off while using any one of them.

It is therefore irrelevant whether you have a Chromecast from the first generation or the most recent Google TV version.

Google Home App

You must first download the Google Home app before you can begin configuring your Chromecast. Not to be confused with the app named “Chromecast.” I am aware that the situation is bewildering. 

Downloading Google Home app

With the Chromecast app, you can screencast your smartphone or tablet directly to your television once you’ve set it up.

You can cast images and videos from these devices to your television using the appropriate HDMI cable.

But to get your Chromecast set up, you’ll need to download the Google Home app on your device.

It’s now as simple as downloading this free app from Google Play or Apple App Store to your iOS or Android device.

Google Smart Speaker

The Google Home brand refers to a range of smart speakers that Google manufactures.

Along with the speaker, the newer products also feature a visual display. To control Chromecast via WiFi, you will need these items. Verify that everything works and can be set up for use.

Google Home device

To turn off your television using a Chromecast, use any of the following Google Home devices:

  • The original Google Home speaker.
  • 1st or 2nd gen Google Nest Mini speaker.
  • Google Home Mini speaker.
  • 1st or 2nd generation display for the Google Nest Hub.
  • Google Nest Hub Max display.

How To Turn Off TV With Chromecast?

Chromecast allows you to turn off your TV in a few different ways:

  1. Enable HDMI-CEC on TV.
  2. Connect your Chromecast and TV.
  3. Set up your Chromecast.
  4. Set up your Google Nest device.
  5. Use Chromecast to Turn off your TV.

 Enable HDMI-CEC On TV

You will need to activate HDMI-CEC since most TVs have this feature disabled by default. To enable HDMI-CEC on your TV, use the following steps:

  •  Go to your TV’s Settings menu.
Tapping on Settings
  •  Find the option for HDMI-CEC in the menu for configuring your TV by navigating to that menu. 
  • In most cases, you may access it via the system’s menu and quickly turn it on.
Toggling the HDMI-CEC on
  • If you cannot find the option, try Google! Search for the TV model + “how to enable HDMI-CEC.”

Connect Your Chromecast And TV

If the HDMI-CEC feature is enabled on your TV, plug your Chromecast into an available HDMI port.

The HDMI cord of the Chromecast should be plugged into the HDMI port on your TV, while the other end is to be plugged into a wall outlet.

There is an important message here! Ensure that the Chromecast is powered by plugging it directly into an electrical outlet.

This automation cannot be performed if you power the Chromecast only through the TV’s USB port.

Connecting Chromecast to your TV

In summary, connect the TV to the wall, the HDMI end of the Chromecast to the TV’s HDMI port, and the power end of the Chromecast to the wall.

Set up your Chromecast

The next step is to configure your Chromecast device. To do this, check to see that your television is switched on.

You should see a screen that says, “Get the app.” If you do not see this, use your remote control to select “Source” and “HDMI.”

Get the app section

Google Chromecast can be set up by following the steps below:

  • Download the Google Home app on your phone or tablet. 
Download the Google Home app
  • You must create an account to use the Google Home app. Let’s go ahead and do that.
  • Upon completing the steps necessary to set up your Google Home account, tap on the + icon at the top left of the screen.
Clicking on + sign
  • Choose “Set up device” from the menu.
Pressing Set up device
  • Then, click “Set up new devices.”
Tapping on Set up new devices
  • Add the Chromecast to your home by selecting it.
  • Google Home will now automatically begin “looking for devices.”
Chromecast looking for devices
  • If your TV and Chromecast are both on, you should be able to use your Chromecast with Google Home. Your phone and TV will display a four-letter/digit code.
  • Verify that the code on your phone matches the code on your TV. Click “Yes” if it does.
Verifying code
  • The last step is to connect the Chromecast to your WiFi network.
Connecting to WiFi
  • You can restart your Chromecast if it isn’t connecting to your Wi-Fi.
  • You’re all set up with your Chromecast now!
Chromecast is ready

Set Up Your Google Nest Device

The finish line is in sight! After you have enabled HDMI-CEC and configured Chromecast on your TV, you are ready to set up the Google Home device, which is the heart of your system.

The good news is that this step should be a breeze. Once you’ve configured the Google Home app, you can just plug your Google Home into an outlet, and as soon as it powers on, it’ll be recognized by the Google Home app.

If your Google Home app does not automatically detect your device, there is no need to worry about it.

Just follow the same steps for Chromecast setup, and everything should be fine.

While setting up the Chromecast, ensure that the WiFi network you select matches the WiFi network your Chromecast is on.

When you choose that network, the Google Home app should automatically connect to that network using your WiFi password (from the Chromecast setup).

Make sure that the “room” where your Google Home is located is the same room where your Chromecast is. It is not a big deal if you do not complete this step. Later on, you can make changes to it if you want.

Use Chromecast To Turn Off Your TV

After you follow the steps above, the Google Home app should show your TV and Google Nest. Don’t hesitate to try it out! Chromecast lets you turn your TV on and off using the following commands:

  •  After turning off the TV, say, “OK, Google, turn on the TV.” Chromecast will turn on your TV within seconds when Google Home tells it to.
  • Furthermore, you can also do it in the reverse direction. Just say, “OK, Google, TV off.” Hopefully, your TV will turn off within a couple of seconds.

Additional Google Home Commands To Try

Volume Control

  • “Ok, Google, lower the TV volume.”
  • “Ok, Google, volume up on the TV.”
  • “Ok, Google, adjust the TV volume to 50.”
  • “Ok, Google, reduce the TV volume by 20%.”
  • “Ok, Google, mute the TV.”
  • “Ok, Google, unmute the TV.”

Channel Control

  • “Ok, Google, change the channel to 91 on TV.”
  • “Ok, Google, next channel.”
  • “Ok, Google, channel up/down on TV.”

Playback Control

  • “Ok, Google, fast forward/rewind on TV.”
  • “OK, Google, play/pause/resume/stop the TV.”

How Do I Fix A Chromecast That Doesn’t Work With My TV?

You can try these steps if your Chromecast does not work with your TV:

  • Make sure your Chromecast software is up-to-date.
  • The TV should be powered on and off again.
