1. Network issues

It would be difficult to experience smooth screening if there’s a network issue. So if your WiFi connection is not steady, you will most likely encounter issues. An unsteady network can contribute to your Chromecast not working.

2. Unsteady power supply

The unsteady power supply can often contribute to the Chromecast needing to be fixed. We all experience TV blackouts when there’s either a low electricity supply or if there’s a malfunction of any sort. You might quickly refer to your smart TV as the fault.

However, if you look closely, you’ll discover that the real culprit is not far-fetched- an unsteady power supply.

3. Device connection issue

Sometimes the problem is what you can fix in a flinch. If your Chromecast device is not properly connected to the HDMI (High Definition Multimedia Interface), it would be impossible to stream your favorite content on your TV without glitches.

So you should check if the problem is just a connection issue.

4. Request for an update

If you are not attentive enough, you might be unaware that your chrome browser or app is seeking updates. Chromecast itself, for many cases, needs an update, so if you can’t, for any reason, cast to your Chromecast, you can check for updates.

These are some reasons for the common issues a Chromecast could encounter that would cause your Samsung TV Chromecast not to work.

Let’s learn what you can do to fix the Chromecast issues. Ready?

Samsung TV Chromecast not Working: What To Do!

Solution 1: Check for connection issues

If the Chromecast device is properly connected to your HDMI, it will not successfully cast on your Samsung TV from your mobile device. And if the mobile device does not recognize your Samsung TV, you cannot stream your content.

So, the first thing to always check is connection issues. Ensure that the Chromecast is properly connected to the HDMI.

Solution 2: Check the WiFi connection

You should check your WiFi connection to ensure it is steady. If your WiFi connection is faulty, it interrupts you from streaming your favorite content.

Solution 3: Ensure both Chromecast and TV are connected to the same network

Closely related to WiFi connection, another underlying issue contributing to your Samsung TV Chromecast not working is when Chromecast and TV are not connected to the same network.

Having a WiFi connection is one thing. Having both devices connected to the same connection is another thing. So, ensure both Chromecast and TV are connected to the same network. If this is done, you can stream your favorite content without hitches.

Solution 4: Check the functionality of your router

If your router is outdated, it will affect your internet speed or WiFi connectivity. You can imagine the frustration of handling a poor internet connection with just a mobile phone, let alone when it has business with TV- it is inconvenient.

If this is the case, it contributes to your Samsung TV Chromecast not working.

If you can update your router, then you will experience a notable change in internet speed. If you doubt your internet speed is up-scaling, then you can test your internet speed with any device that permits for that.

Check and ensure that you are satisfied with the new upgrade on the internet, and if you are not, then it is best to contact your ISP and request a quick fix.

Solution 5: Reset your router

Something all your Chromecast needs to work is a quick boost in your router. Using the router will, over time, make the router load slower than before.

More so, if you are using older routers, you may opt for upgrading older routers using outdated wireless standards, which can affect the streaming process.

How can you do this?

  • Try to have a look at the backside of your router to get the reset button
  • You can use a pin to press that button and hold it for some seconds- 30-40 seconds, preferably.
  • Congratulations, you have reset your router. Check if the issues are resolved.

So, what if the routers are not the issue? What else can you do?

6. Solution 6: Reboot your TV

If you have temporary cache files that are damaged or corrupted, it will interrupt your streaming from your mobile device to your TV.

What is the best way to correct this error? For the time being, rebooting your TV is the preferable option for getting the potential threat tamed.

Rebooting your TV will leave your TV refreshed as it will start afresh without the cache files. You should check if this has resolved the problem. Your Samsung TV Chromecast should respond positively if this is the problem.

7. Solution 7: Check or Update Samsung TV’s operating system

Constantly updating your TV helps in fixing bugs and helping the TV stay up to date, having other new functionalities. So, if you do not update your TV, it can smoothly affect the TV Chromecast performance.

If you want to update your TV OS, use a USB flash drive or directly connect it to the internet and update it.

Note: this step might vary depending on your Samsung TV’s model or brand. So, you must work with the manufacturer’s manual, so you are fully aware of the steps you are taking.

8. Solution 8: Perform a factory data reset on your Chromecast

If you try out all this and your Chromecast is still not working, then this is the time to perform a factory data reset on your Chromecast. You may lose your data when performing a factory reset on your Chromecast.

Setting up your Chromecast from scratch again is easy.

  • Press down the Chromecast button on the back of the device for about 20-30 seconds.
  • Your TV, after some time, will go blank, after which the reset will begin.
