Discovery Plus Not Working on Samsung TV

If Discovery Plus is not working on your Samsung TV, turn off your TV, unplug it from the power source and wait for 60 seconds, plug it back in and turn it back on. Now, open the Discovery Plus app on your TV and it should start working.

If you are asking: Why is Discover Plus not working on your Samsung TV?

There are so many factors that can cause the Discovery Plus app to not work on your Samsung smart TV ranging from device incompatibility to poor internet connection, corrupt app and cache files, outdated app, outdated Samsung TV tizenOS software, or even server issue from Discovery Plus.

Now, let’s take a look at a step-by-step process to fix the issue, starting from the most common causes with highest chance of fixing the issue, down to the less likely but still effective methods.

1. Check if Your Samsung TV is Compatible

Not all Samsung smart TVs are compatible with Discovery Plus app. Before anything, you need to be sure that your smart TV is actually compatible with Discovery Plus.

For now, Discovery Plus is available on most Samsung Smart TVs released from 2017 to the latest models using tizen OS.

If your Samsung tizenOS smart TV is compatible, then you can move to the next step below.

However, if your TV is not compatible, but you still want to stream Discovery Plus on your TV, there are at least 2 alternative means to watch Discovery Plus on your Samsung TV which I will show you later in this guide.


2. Power Cycle Your Samsung TV

Power cycling can help fix a lot of streaming issues on your smart TV. It can help fix unresponsiveness, black screen, crash, lag while streaming. It also removes corrupt cache files that can cause streaming apps like Discovery Plus not to work on your smart TV.

Power cycle is also known as a ‘Soft reset’ (differs from factory/hard reset in that all your settings and configurations remain untouched).

Here’s how to power cycle your Samsung TV and fix this issue with Discovery Plus app not loading:

  • Unplug your TV from power outlet
  • Leave it unplugged for 30 seconds
  • Press the power button on your TV for 30 seconds (if your TV does not have a power button, you can skip this step). 
  • Plug the TV back into the power outlet and it should start working normally now.

If that fixed the issue for you, great! Otherwise, move to the next tip.


3. Check Your Internet Connection

A slow or unstable internet connection can cause Discovery Plus app to not work on your Samsung TV. First thing you can do is restart your network router.

To do this, unplug your router, wait for 30 seconds and plug it back in. Once this has been done, connect your Samsung smart TV to your router and try to access Discovery Plus again. That should fix any connection issue and Discovery Plus app should start working on your Samsung TV.

There are a couple of other things you can do to fix any potential network issue, you can find some of them below:

  • Switch to hardwire connection (i.e ethernet cables)
  • Check ethernet cables (in the case of wired connection)
  • Check your network or connection speed (from other channels or from another device)
  • Switch to a dual-band router and use the 5.0GHz frequency
  • Update DNS to Google DNS

How to Update DNS to Google DNS

  • Go to Settings with your Samsung TV remote controller.
  • From the settings page, click on the General tab

click on general settings tab

  • Click on Network 

select network settings

  • Next, select Network Status

click on network status

  • Under your connected network, click on IP Settings

select IP settings

  • Select the option to set DNS manually
  • Finally, edit the DNS Server and change it to 8.8.8.8

enter DNS server manually

  • Finally, click on OK button

Wait for it to be reconnected to the new DNS server and then restart your smart TV.

Now, go back to your Samsung TizenOS TV, open the Discovery Plus app and it should be working perfectly well if network is the source of the issue.

You should take note of one thing though.

Obviously, it’s more likely to be a network issue if other channels like Netflix, YouTube, Hulu, Disney+ and others are not as well on your Samsung smart TV. On the other hand, if these other channels are working, then network is very unlikely to be your issue.

If the issue is network and you have been able to fix it, great! Otherwise, let’s move to the next step. 


4. Update Discovery Plus App

Another common reason why Discovery Plus app stops working on Samsung smart TV is having an older version of the app installed. It can cause Discovery Plus to show a black screen or crash suddenly on your Samsung smart TV.

In that case, you need to check if you have installed the latest version, and if not, you need to update and install the most recent version of Discovery Plus on your TV. Here’s how to do that:

  • From the home screen, navigate to the button menu and click on ‘Apps’

click on Samsung TV apps icon

  • On the apps screen, navigate and click on Discovery Plus app icon
  • On the Discovery Plus app description page, you will find ‘Update App’ button if your Discovery Plus app is not the latest version. In that case, go ahead and update it. Otherwise, you will find the ‘Open’ button.

On the same page, you will also find details showing the latest version number of the app and installed version number currently installed on your TV just below the Update/Open button. If they match, then you have the latest version installed. 

In addition, you can also turn on auto update for apps by clicking on the settings at the top right corner of the apps page (not Discovery Plus app page, but ‘All apps’ page)

That will ensure that all your apps are up to date. 


5. Clear Discovery Plus App Cache

Cache files build up and are stored as you use apps installed on your Samsung smart TV. The longer you use them, the larger these cache files become. In some cases, these cache files become corrupt and affect the performance of the apps on your smart TV.

Hence, you need to clear the cache file to get your Discovery Plus app to load afresh. In fact, it is recommended that you clear app cache files regularly for optimum performance. Once cleared, Discovery Plus app should start working on your Samsung TV again.

9. Check If Discovery Plus Server Is Down

At this point, before we continue looking for other potential causes of the issue on your Samsung smart TV, it’s about time we looked at a potential cause from Discovery Plus.

Although not common, Discovery Plus streaming server can be down sometimes even in 2022. In such instances, the issue is a general one from their servers and is not specific to you or your Samsung smart TV.

When this happens, you could experience a number of things like Discovery Plus app crashing suddenly, you may be logged out of your account out of nowhere and being unable to log back in or the app might just show a black screen on your Samsung TV.

  • You can also check if Discovery Plus app works on other devices like mobile phone, PC or other streaming devices other than you Samsung TV. If it doesn’t, that’s another proof that it could be a general issue. 

10. Update Date & Time

Have you ever tried to visit a website on your phone or laptop and it does not connect to the internet because of incorrect date and time? Well, it does happen!

One of the reasons why this happened is that an incorrect date and time cause show an expired or invalid Public Key Infrastructure (PKI) certificate (a digital certificate used to authenticate users, servers, or devices online). As a result, you fail to get an internet connection.

The same way, it can happen while trying to open apps like Discovery Plus on your smart TV.

What you need to do it simple: Set the correct date and time for your time zone, and in addition, set the time and date to automatically update. 

  • To change the time and date, go to Settings > General > System Manager > Time > Clock
  • Make sure the clock mode is set to ‘Auto’. More importantly, make sure the time and date are correct. Otherwise, check your TV internet connection and restart it.

  • If it’s still not fixed after ensuring it is connected to the internet, go ahead and choose the manual option and set it yourself.

Once the time and date are corrected and your smart TV is connected to the internet, you shouldn’t have problem with it anymore.


11. Check for Geo-restrictions

While Discovery Plus is making efforts to ensure that the streaming service is available in all major countries, it is not yet available in some regions.

For now, it’s only available to watch in the US, Canada, Brazil, and parts of Asia and Europe.
