Being able to control your Samsung TV with a voice assistant like Alexa has to be one of the coolest feelings ever. But sometimes along the setup, there are several pitfalls you can run into.

Full disclosure: my Samsung TV (QN90B) is constantly having this issue. It never fails to turn it off but has issues turning it back on. I’ve just about given up on it, but these solutions below do work.

Why Alexa Won’t Turn on Samsung TV – Solutions

1. Your TV is connected to an Ethernet cable

When your Samsung TV is using an ethernet cable to be hard wired for an internet connection, it can provide very fast speeds. But, when the TV is powered off, your Samsung TV can’t communicate with services like the Alexa App.

Try removing the cable and connecting your Samsung TV to a Wi-Fi network.

2. The name of the Samsung TV is complex

Named Samsung TVs in the Alexa app

Try naming your Samsung TV to something like this:

  • Living Room TV
  • Bedroom TV

It will be easier to say to Alexa and easier for Alexa to register what device name you are stating.

3. Need to disconnect and reconnect TV from SmartThings App

Sometimes, all we need to do is to restart the process. Turn it off/on. This is the same deal, disconnect the Samsung TV from your SmartThings app and re-add it back on. (Steps below)

4. Need to disconnect/reconnect SmartThings Skill from Alexa App

This will also apply to the Amazon Alexa app. Removing and disable the SmartThings Skill, and re-install it. Make sure not to install the Classic SmartThings app. (Steps below)

5. Device lost Wi-Fi Connection

Is your Samsung TV still connected to the internet? Check in your Network settings and test the connection. Having your smartphone on the same Wi-Fi network is always a good idea.

6. Poor Wi-Fi Connection

If you have poor network connection, it could cause a delay or lag when Alexa is trying to communicate to your SmartThings app.

Check out Speed Test and perform these tests on your mobile phone and Samsung TV to check your speeds. If you have speeds under 30-40 Mbps I would consider trying to boost your speeds.

Try resetting your router first by unplugging it for 60 seconds and plugging it back in.

7. Update Your Apps

Apps are always releasing new updates to provide users with new features and patch old bugs. You may have an old outdated version which needs to be updated. Update your:

  • Samsung TVs software
  • Amazon Alexa app
  • SmartThings app

I would even consider uninstalling each app and reinstalling it if you are still having issues.

8. Your Samsung TV Isn’t a Smart TV 

It’s important to note that your Samsung must be a Smart TV in order to connect, by itself, to your Alexa. 

If your Samsung TV can connect to the internet, it is a Smart TV.

Most models after 2018+ will work in this situation, older models will not be able to use this functionality.

If this is the case, consider getting a smart plug where you can turn on the TV via the plug with Alexa.
