Alexa Won’t Turn On Samsung TV: How to Fix?

Getting your virtual assistant Alexa to turn on your Samsung TV should be easy and convenient. However, sometimes things don’t go as planned, and Alexa fails to power on the TV even when asked. This can be frustrating when you’ve become accustomed to using voice commands for daily tasks.

Don’t worry – in most cases, this problem can be fixed with some simple troubleshooting. This guide will walk you through the major reasons why Alexa might not turn on your Samsung TV and provide step-by-step instructions for resolving the issue.

Prerequisites

Before diving into troubleshooting, let’s go over what needs to be in place to use Alexa to control your Samsung TV:

  • A compatible Alexa device like an Amazon Echo or Echo Dot
  • The Alexa app set up on your smartphone or tablet
  • A Samsung TV from 2016 or later that supports HDMI-CEC
  • Your TV is connected to power and turned on
  • The TV and Alexa devices are connected to the same WiFi network
  • The Samsung SmartThings skill enabled in your Alexa app
  • Your Samsung TV account linked in the SmartThings skill

If all those elements are set up correctly, Alexa should be able to turn on your TV with a simple voice command. If not, the problem likely lies with one of those prerequisites not configuring properly.

What to Do When Alexa Won’t Turn on Samsung TV?

Make Sure TV Supports HDMI-CEC

HDMI CEC SAMSUNG TV

The first thing to check is whether your Samsung TV model supports HDMI-CEC. This standard allows HDMI-connected devices to communicate and share functionality with each other. The Alexa integration relies on HDMI-CEC to send the power on/off signals.

To check if your TV has HDMI-CEC:

  • Access your Samsung TV settings menu
  • Navigate to General > External Device Manager > Anynet+ (HDMI-CEC)
  • Verify that Anynet+ (HDMI-CEC) is enabled

Any Samsung smart TV model from 2016 or later should have HDMI-CEC capabilities. If your TV is older than that or you find that the setting is disabled, then Alexa cannot turn on the TV.

Unfortunately, the only solution for older TVs is to look into upgrading your set to a newer Samsung model. For TVs that support HDMI-CEC, be sure that functionality is enabled before moving on to other troubleshooting.

Make Sure Alexa and TV Are on the Same Network

CONNECT TV AND PHONE IN SAME WIFI

Alexa and your Samsung TV must be connected to the same local network to communicate. This connectivity happens through the SmartThings app and skill, which are the intermediaries between the two devices.

To check your network connections:

  • In the Alexa app, go to Devices > + and select Add Device
  • On your TV, go to Settings > General > Network > Network Status
  • Verify both display the same network name

If Alexa and your TV show different network names, then communication will fail. Troubleshoot your connections by doing the following:

  • Disconnect/reconnect both devices from the network
  • Check if network issues are preventing connectivity
  • Test connectivity using the Alexa app or SmartThings app network diagnostics
  • If issues persist, unplug the router and TV for 60 seconds to reset

Once Alexa and your Samsung TV are reliably showing the same network name, move on to ensure the next prerequisite has been met.

Enable SmartThings Skill

ENABLE SMART THINGS

The Samsung SmartThings skill is what gives Alexa control over Samsung smart devices, including powering TVs on and off. So, this skill needs to be properly enabled.

To check if SmartThings is enabled:

  • In the Alexa app, go to Menu > Skills & Games
  • Search for “SmartThings” and select the skill by Samsung
  • Verify the toggle switch is in the Enabled position

If SmartThings is not enabled, flip the toggle to activate it. You’ll then need to link your Samsung account for authorization.

On the skill page, select Link Account and sign into your Samsung account that was used to set up the TV. Follow the prompts to link SmartThings with Alexa.

Once successfully linked and enabled, the skill may now allow Alexa to turn your TV on or off.

Set Up the Device in the SmartThings App

SETUP SMARTTHING DEVICE

Another prerequisite is setting your TV up as a device in the Samsung SmartThings app. This app controls Samsung smart devices and enables integration with Alexa.

To check if the TV is an added device:

  • Open the SmartThings app on your mobile device
  • Go to Devices > Add Device
  • Verify your TV is shown under Added Devices

If the TV hasn’t been added, tap to add device and select your TV model. Follow the setup prompts to get your TV fully linked to SmartThings.

Sometimes, you may need to enable permissions in SmartThings for Alexa control. Under the TV device details screen:

  • Select Device Options > Voice Control Permissions
  • Ensure options like Turn Off, Turn On, etc are enabled

With your TV now discoverable and permitted for voice control, Alexa should be able to power the set using SmartThings integration.

Check Outlets, Cables, and Power

For Alexa’s signals to turn the TV on effectively, the TV must remain connected to a working power outlet. It’s possible connection issues are preventing Alexa’s requests from being received by the powered-down TV.

Some things to verify in this step:

  • TV is connected to a wall outlet that is confirmed to be working
  • Power cables are fully inserted into the TV and outlet
  • TV’s remote power buttons turn set on when pressed
  • TV’s standalone power button turns set on when pressed
  • The TV power mode is in Instant-On rather than Eco

If the remote and manual power buttons still don’t power up the set, then either the outlet has failed, the power cable is damaged, or the TV has a hardware issue preventing power up.

Continue troubleshooting by:

  • Trying another working outlet in your home
  • Using different power cables if available
  • Running a power reset by disconnecting cables and outlet for 1 minute

Once you can fully power your TV independently using the provided remote or hardware buttons, the sound connectivity should allow Alexa access again, too.

Re-link Accounts

Issues with properly linked accounts could cause authentication errors, blocking Alexa from successfully communicating with your Samsung TV.

To rule out account linkage problems:

  • Open the SmartThings app and disconnect your Samsung account under Settings
  • In the Alexa app, go to the Skills menu and disable the SmartThings skill
  • Delete all TV devices shown in the Alexa app’s Devices menu

Then re-authenticate by:

  • Enable the SmartThings skill again in Alexa and link your Samsung account when prompted
  • In SmartThings, re-add your TV as a device through device discovery
  • In Alexa, add devices and select the option for SmartThings devices

This refresh of your Samsung and SmartThings authentication should sync up all permissions accurately. Test if this resolved any account conflicts by asking Alexa to turn your TV on or off.

Factory Reset Alexa Devices

FACTORY RESET ALEXA DEVICE

If you’ve gone through all the troubleshooting steps and Alexa still fails to power your Samsung TV, your last resort may be a hardware reset of Echo devices.

Resetting to factory settings will remove any corrupted data or configurations on that Alexa device and start fresh.

The steps will vary by model but generally involve:

  • Accessing the device settings in the Alexa app
  • Selecting options to reset or factory restore the device
  • Confirming reset when prompted
  • Re-adding your Alexa device when back online

A hassle, yes, but hardware resets are crucial for eliminating complex software issues. This should wipe clean any problematic settings on Alexa hardware or connectivity that remained for some reason.

After a reset, attempt to add your TV in SmartThings again and enable TV power voice controls. If the issues persist across different devices even after resets, you likely need to contact Amazon Echo or Samsung SmartThings customer support to investigate further.

But in most cases, a reset gives Alexa and SmartThings integration a much-needed fresh start. Remember to re-configure your Alexa commands afterward to regain normal voice control functionality.

Get Help from Samsung or Amazon

Troubleshooting technology failures takes patience. We hope this guide has helped identify potential culprits in why Alexa refuses to switch on your Samsung television.

The step-by-step process should resolve common connectivity or configuration problems between Alexa devices, your WiFi network, Samsung accounts, and HDMI-CEC capabilities.

  • Contact Amazon Echo Support for Alexa device issues
  • Contact Samsung SmartThings Support for app issues
  • Contact general Samsung Support for television hardware or firmware issues

Device specialists can further diagnose why Alexa’s signals are blocked from reaching your TV. Relief from technology headaches awaits! Just keep calm, retrace steps, try alternative solutions, and don’t hesitate to ask the experts.

Now get back to powering up entertainment hands-free and leaving remote control battles in the past!
