How to Fix Google Assistant Not Turning Off TV

Most of the issues that cause Google Assistant to stop responding to the command to turn off the TV can be easily solved.

So, here’s what to do when your Google Assistant won’t turn off the TV.

Step 1: Update TV Software

Many people have reported that whenever their TVs have a new update, Google Assistant stops responding to commands like “turn off the TV.” So, the first thing that you should do is update your TV.

This process may differ slightly from one TV brand to the next, so we’ll focus on the top brands.

To update Samsung smart TV, you should:

  1. Click Settings or Menu on your remote
  2. Select Support
  3. Click Software Update
  4. Click Update Now
  5. Keep the TV on until the update is complete

Updating Google TVs and Android TVs may vary slightly from model to model, but there are general steps that you can follow.

Here’s how to update a Google TV:

  1. Press Quick Settings on the remote
  2. Select Settings
  3. Select System
  4. Click About
  5. Select System Software Update

To update Android TV, here’s what to do:

  1. Click Help or the Home button and  then Help on the remote
  2. Select Status & Diagnostics
  3. Click System Software Update

Step 2: Update Chromecast Firmware

Google Chromecast firmware is typically updated automatically. These updates, however, can occasionally be staggered. So, if you’re using Google Chromecast, the problem could be due to out-of-date firmware.

You can wait for the update to download automatically, which may take several days. You can also try to prompt the device to update.

When Chromecast reboots, it usually tries to download and install the latest available firmware.

Here’s how to prompt your Chromecast device to update:

  1. Turn on the Chromecast device
  2. Download the Google Home Android app or the Google Home iOS app
  3. Connect the smartphone and Chromecast device to the same WiFi network
  4. Locate the Chromecast device on the app
  5. Tap the Chromecast device to get an overview of it
  6. Tap the gear icon
  7. Tap the three horizontal dots icon
  8. Tap Reboot to reset the Chromecast

Step 3: Power Cycle the TV

Google Assistant may not respond to your command due to a temporary glitch. The quickest way to resolve any issues is to power cycle the TV. If you have Google Home or Chromecast, you should also power cycle them.

Here’s how to power cycle any electronic device:

  1. Unplug the device from the power socket while it’s turned on
  2. Leave the device unplugged for at least one minute and up to 10 minutes
  3. Press and hold the power button if your device has one for five seconds
  4. Replug the device into the power socket

Google Assistant should work properly now. So, after your TV and Google devices turn on, command Google Assistant to turn off the TV.

Step 4: Turn On Consumer Electronics Control (CEC)

Consumer Electronics Control (CEC) is a feature that allows users to control multiple HDMI-connected devices from a single remote. If your Google Assistant is linked to your TV via Google Home, disabling CEC may prevent your TV from receiving commands.

To make sure that CEC is turned on, here’s what you should do on Samsung TV:

  1. Click Settings on the remote
  2. Select Settings
  3. Look for General or Connection
  4. Select External Device Manager
  5. Click Anynet+ (HDMI-CEC)

To turn on CEC on Google TV and Android TV, you should:

  1. Open Settings
  2. Select Device Preferences
  3. Click HDMI CEC
  4. Select CEC Control
  5. Toggle the CEC Switch to turn it on

Step 5: Contact TV Manufacturer

If all else fails, there could be a serious problem with the TV. In that case, it’s best to contact the manufacturer so that a professional can figure out what’s wrong.


Google Assistant is designed to make life easier. So, it can be a frustrating experience when it won’t turn off the TV.

Luckily, with some troubleshooting and patience, you should be able to fix whatever is causing the issue. You may need to go through several steps to get your Google Assistant to respond to your commands again, so make sure you follow the steps in our article!
