Netflix Not Working on Roku? Solve It Now

Sometimes people meet various errors or issues of Netflix not working on Roku TV, like constant crashing, buffering, black screen, etc. These issues could quickly ruin a movie night. After troubleshooting multiple Roku devices over time, I’ve learned exactly what causes these problems and more importantly how to fix them. This guide will show you what I have done to fix Netflix not working on Roku TV issues.

Netflix Keeps Crashing on Roku TV

Among all Netflix streaming issues on Roku TV, one of the most common issues I’ve encountered is Netflix keeps crashing on Roku TV. Whenever I start Netflix app on Roku TV, the app either closes randomly or refuses to load entirely.

From my personal experience, I have summarized the below causes for this issue: outdated Netflix app, outdated Roku system software, corrupted Netflix cache or temporary data, or low device memory, especially on older Roku TVs.

Therefore, upon these potential causes of Netflix keeping crashing, I have tried the below fixes:

Solution 1: Update Netflix app on Roku
On Roku Home page, choose and highlight Netflix app, press the Star (*) button on remote controller, and then choose "Check for updates" option. Once an update is available, update it. 

Solution 2: Update Roku software to the latest version
On Roku Home page, open the "Settings" app and then choose "System > System update > Check Now" to check for available update. Once an update is available, update it.

Solution 3: Clear cache of Roku TV
The Netflix cache clearing feature is a hidden feature on Roku. I have tried multiple times to make it work smoothly. Follow these steps on how to clear Netflix cache on Roku TV: Go to the Roku TV Home screen, on remote controller, press Home 5 times, Up 1 time, Rewind 2 times, and then Fast Forward 2 times. Roku TV will then restart, during which cache will be cleared. This hidden Roku TV reset clears all cache and often fixes crashes instantly for all apps.

Solution 4: Reinstall Netflix
Sometimes even there is no Netflix app update available, reinstalling Netflix app could help solve many issues. It’s just like resetting Netflix on Roku TV. Then how to reset Netflix on Roku? To uninstall Netflix on Roku TV, go to the Home screen, highlight Netflix, press the Star (*) button on remote controller, and then select "Remove channel" option. To re-install Netflix on Roku TV, open the Streaming Store, find Netflix and then click "Add channel". It is highly recommended you restart Roku TV after uninstalling Netflix on Roku to clear cache.

Netflix Keeps Buffering or Freezing

Another issue I, and most of you, no matter which streaming service you are using, frequently met was endless video buffering. This has been one of the most commonly seen problems in online streaming, especially when your network connection is poor.

According to my own experience, the below solutions might fix the Netflix keeps buffering or freezing issue on Roku TV and other devices.

Solution 1: Check internet network connection speed
Streaming different Netflix content requires different network speed. Netflix recommend 3 Mbps for SD video streaming, 5Mbps for HD video streaming and 25Mbps for 4K video streaming. Therefore, you can run a speed test to check your internet connection speed and then set corresponding quality for Netflix video streaming.

Solution 2: Lower down streaming quality
The lower video quality you set, the smoother the video streaming becomes. On your Netflix Account, open the "Playback Settings > Reduce quality" option, or directly choose streaming quality on the playback screen to lower down streaming quality.

Solution 3: Restart router
Restart your router to fix the router issue. This simply helped me fix video buffering.

By trying the above solutions, you should have been able to fix the Netflix keeps buffering or freezing issue on Roku TV and other devices. Another pro tip to avoid Netflix buffering is to download Netflix videos for offline viewing. I tried a Netflix video downloader namely Moyea Netflix Downloader to download Netflix movies and TV shows to save as standalone MP4 files, which could then be played back on Roku TV and various other devices without any buffering or freezing. It is a wonderful solution if you get a very slow or even no internet.

Netflix Black Screen or No Video

Another frequently seen issue: Netflix black screen or no video on Roku TV. This happens on all devices actually, and I met with this issue for a few times. There is only sound but no image on my Roku TV. At the very first, I tried restart my Roku TV, Netflix channel, and even checked my Netflix account, but none of them ever worked. This happens most due to: HDMI or HDCP compatibility, incorrect display resolution settings, and TV or Roku handshake problems.

I tested some of the suggestions and found these fixes worked for my Roku TV:

Netflix Audio Not Working on Roku

In such case, you will see video image but there is no sound while streaming Netflix on Roku TV. Honestly, I haven’t come across this issue. Therefore, all these potential causes and feasible fixes are based on Netflix official and online feedback from various platforms. The possible causes of Netflix no sound issue might be: audio format mismatch, incorrect audio settings on Roku, or improper speaker system settings.

To fix the Netflix audio not working on Roku issue, I would like to suggest you first check whether it is on the Netflix side. Some Netflix videos might have audio issue. You can try to stream the Netflix video that has no sound on Roku on other devices like your smartphone to see if the sound streams normally.
