How To Turn Off The TV With Chromecast? (Easy Fix)

It’s a game changer to be able to control your TV with your smartphone or just your voice. There will be no more searching for that misplaced remote buried beneath the bed covers or deep within the couch.

To use Chromecast to turn off your TV, first enable HDMI-CEC on your TV and then connect your Chromecast to your Google Home via the Google Home app! If you plug your Chromecast directly into a wall outlet rather than the TV, it will not work.

Before we get into the specifics of how to turn off your TV with Chromecast, let’s go over what you’ll need to get started. I’m going to assume you already have a smartphone/tablet and a WiFi network.

1. TV with HDMI-CEC

The first thing you’ll need is an HDMI-CEC-capable television. You simply won’t be able to turn off your TV with Chromecast without this capability.

HDMI-CEC is an acronym that stands for HDMI Consumer Electronics Control. It’s a feature that allows your TV to interact with and work with other devices. The issue is that most TV manufacturers don’t call it “HDMI-CEC,” but rather something else.

Here is a list of the most common TVs with HDMI-CEC and their associated brand name, so you can easily identify it.

  • AOC – E-link
  • Insignia – INlink
  • LG – SimpLink
  • Mitsubishi – NetCommand
  • Onkyo – RIHD
  • Panasonic – VIERA Link, HDAVI Control or EZ-Sync
  • Pioneer – Kuro Link
  • Runco International – RuncoLink
  • Samsung – Anynet+
  • Sharp – Aquos Link
  • Sony – BRAVIA Link or BRAVIA Sync
  • Toshiba – Regza Link or CE-Link
  • Vizio – CEC

2. Google Chromecast

After you’ve confirmed that your TV supports HDMI-CEC, you’ll need to obtain Google Chromecast. Chromecast is a device that connects to the HDMI port on the back of your television.

It then allows you to use your smartphone as a remote control to stream video content to your TV from apps such as Netflix, YouTube TV, and Hulu. There are several Chromecast models available, but all of them allow you to turn off your TV.

If you already have a Chromecast, that’s fantastic. If not, you should get the most recent version: Chromecast – 3rd generation.

  • Chromecast (1st generation) – Sales discontinued: Sep 29, 2015
  • Chromecast (2nd generation) – Sales discontinued: Oct 10, 2018
  • Chromecast (Ultra) – Current generation – Released on Nov 6, 2016
  • Chromecast (3rd generation) – Current version – Released on Oct 10, 2018

3. Google Home App

This app is not to be confused with the “Chromecast” app. I know it’s perplexing. After you’ve set up your Chromecast, you can use the Chromecast app to screencast your phone or tablet directly to your TV. You can even “cast” photos or videos from these devices to your television.

However, in order to set up the Chromecast device, you’ll need the Google Home app. So go ahead and get it for your smartphone or tablet from Google Play or the Apple App Store.

4. Google Home

Google Home is a smart speaker product line created by Google. In addition to the speaker, newer products include a visual display.

All of these Google Home models can be used to turn off the TV via Chromecast.

  • The Original Google Home – speaker
  • Google Home Mini – speaker
  • Google Home Max – speaker
  • Google Home Hub (aka Nest Hub) – 7 in visual display and speaker
  • Google Home Hub Max (aka Nest Hub Max) – 10 in visual display and speaker


Now that you’ve made sure you have everything you need to to actually turn off your TV with Chromecast, let’s jump into the step-by-step instructions.

Step 1: Enable HDMI-CEC on your TV

Most HDMI-CEC-enabled televisions have it turned off by default. It will need to be enabled. To do so, navigate to your TV’s menu, options, or settings and look for HDMI-CEC. I’d start by pressing the “Menu” button on the TV’s remote and scrolling through the menu, looking for this option.

If you’re having trouble finding it, try a quick Google search for “model of your TV” + “how to enable HDMI-CEC.” On my Samsung TV, I recently enabled it by clicking “Menu,” scrolling down to “System,” and then clicking “Anynet+ (HDMI-CEC).” I was then able to toggle it to “On.”

Step 2: Plug your Chromecast into your TV

After you’ve enabled HDMI-CEC on your TV, plug your Chromecast into an available HDMI port on the back of your TV. With the Chromecast’s HDMI cord plugged into your TV, plug the other end of the Chromecast into a wall outlet.

This is critical! Make sure the Chromecast is powered by plugging it directly into an outlet. If you try to power the Chromecast using only the TV’s USB port, you will be unable to perform this automation. To summarize, plug the TV into the wall, the HDMI end of the Chromecast into the TV’s HDMI port, and the power end of the Chromecast into the wall.

Step 3: Setup your Chromecast

It’s now time to set up your Chromecast. To do so, make sure your TV is turned on. The screen should instruct you to “Get the app.” If you don’t see this screen, use your remote to select “Source” and then “HDMI.” Download the Google Home app to your phone or tablet. The Google Home app will prompt you to create an account; please do so.

Begin by clicking the + icon at the top left of your Google Home account. Then click “Set up device.” Then comes “Set up new devices.” Choose the home to which you’ll be adding the Chromecast. Google Home will now begin “Looking for devices” automatically.

Because your TV is turned on and your Chromecast is plugged in, Google Home should detect your Chromecast without issue. When this happens, your phone and TV will both display a four-letter/digit code.

Check that the code on your phone matches the code on your television. If it does, press the “Yes” button on your phone. Then, select which room in your house the Chromecast is in and press “Next.” Finally, you’ll link the Chromecast to your WiFi network. Your Chromecast is now ready to use!

Step 4: Setup your Google Home

After you’ve enabled HDMI-CEC on your TV and set up your Chromecast, the final step is to configure your Google Home. Fortunately, this step should be a breeze. Because you’ve already configured the Google Home app, you should be able to simply plug your Google Home into an outlet and, as it powers on, your Google Home app will detect it.

(If your Google Home app does not automatically detect your device for whatever reason, simply repeat the steps outlined above for Chromecast setup and you should be fine.) When prompted to select your WiFi network during the setup process, make sure it’s the same WiFi network that your Chromecast is on.

Once you’ve chosen that network, the Google Home app should remember your WiFi password (from the Chromecast setup) and connect automatically.

Also, make sure that the “room” your Google Home is in is the same room that you added your Chromecast to. Don’t worry if you didn’t do this; you can go back and edit it.

Step 5: Turn off TV with Chromecast!

If everything is in order, you should now be able to see both your TV and your Google Home speaker in the Google Home app. If everything appears to be in order, give it a shot!

Make sure the TV is turned off before saying, “OK Google, TV on.” Google Home should send a signal to your Chromecast to turn on your TV in a second or two. Alternatively, you can say, “OK Google, TV off,” and your TV should turn off.

Yes, as long as your TV is HDMI-CEC enabled, Chromecast can turn it on without a remote. To use Chromecast to turn on your TV, follow these steps:

  1. Check to see if your TV supports HDMI-CEC.
  2. Connect your Chromecast to your TV’s HDMI port.
  3. Connect the Chromecast’s power cord to a wall outlet.
  4. Install the Google Home app on your smartphone or tablet.
  5. Configure your Chromecast using the Google Home app.
  6. Configure your Google Home using the Google Home app.
  7. Turn on the TV using Chromecast!

Take note that these are the same steps for turning off your Chromecast-enabled TV. When your Chromecast is connected and HDMI-CEC is enabled, it can turn on and off your TV!


If you want to go beyond just controlling your TV, you can use your Google Home and Chromecast with Netflix, Hulu, YouTube TV, and other streaming services. Follow these steps to connect your Netflix account to Google Home:

Select the Menu icon in the upper right corner. Choose Assistant settings. Choose the Services tab, followed by Videos and Photos. Locate Netflix and click the Link icon to connect your Google account to the Netflix app.


If you get a No devices found error message on Chromecast after setting it up, try unplugging the Chromecast and plugging it back into the TV again.

If you aren’t, your Google Home will display the error ‘Could Not Communicate with Your Chromecast.’ To resolve this, perform a factory reset on the Chromecast.
