YouTube on your TV stops working most often because of a weak internet connection, an outdated app, or a sign-in problem

YouTube on a TV requires a stable connection and a current version of the app. If the app crashes, loads slowly, or shows an error code, the first step is always to check your internet speed — YouTube needs at least 2.5 megabits per second for standard video and 25 megabits per second for 4K. If your connection is strong, restart the app, then restart your TV. If that does not work, check whether you are signed in to the correct Google account and whether your account has any restrictions or holds on it.

The fixes below follow the order most likely to work. Start at the top and move down only if the previous step did not solve it.

Key Takeaways

  • Restart your TV and your internet router before trying anything else — this fixes the majority of YouTube failures without any other steps.
  • YouTube needs at least 2.5 megabits per second to play video; if your speed is lower, move your TV closer to your router or switch to a less crowded Wi-Fi channel.
  • An outdated YouTube app will not work on newer TV models; check your TV's app store for updates and install any available.
  • If YouTube loads but video will not play, clear the app's cache and data, which removes temporary files that may be corrupted.
  • If you see an error code, write it down and search for it on Google along with your TV brand — error codes point to specific problems.

Restart your TV and router first

Unplug your TV from the wall outlet and leave it unplugged for 30 seconds. While the TV is unplugged, unplug your internet router as well. Plug the router back in first and wait for all its lights to stabilize — usually two to three minutes. Then plug the TV back in and wait for it to fully start up. Open YouTube and try to play a video.

This step clears temporary memory on both devices and resets the connection between them. It solves most YouTube failures that are not caused by a hardware problem or a permanent account issue. If YouTube works after this restart, you are done. If it does not, move to the next step.

Check your internet speed and connection

YouTube requires a minimum of 2.5 megabits per second to play standard video without constant buffering. If you have multiple devices using the same Wi-Fi — phones, computers, tablets, other streaming devices — the available speed to your TV drops. Test your speed using a phone or computer on the same Wi-Fi network. Go to speedtest.net, run the test, and note the read speed.

If your speed is below 2.5 megabits per second, move your TV closer to the router or ask your internet provider whether your plan supports that speed. If your speed is adequate but YouTube still does not work, your TV may be on a Wi-Fi channel that is crowded with interference from nearby networks. On most routers, you can switch to a less crowded channel using the router's app or web interface — your router's manual or the sticker on the back will show you how to access these settings.

If your TV is connected by ethernet cable instead of Wi-Fi, make sure the cable is fully plugged in at both ends and that the port on the TV is not loose or damaged.

Update the YouTube app on your TV

YouTube stops working on older app versions when Google releases a new version that requires updated software. Check whether your TV's app store has an update available for YouTube. The steps differ by TV brand: on Samsung TVs, open the app store, find YouTube, and look for an Update button. On LG TVs, go to the LG Content Store, search for YouTube, and select Update if available. On Roku, go to the Roku Channel Store, find YouTube, and select Update.

If an update is available, install it and restart the app. If no update is available but YouTube still does not work, your TV may be too old to run the current version of YouTube. Check your TV's manual or the manufacturer's website to see whether YouTube is still supported on your model. If your TV is no longer supported, you will need to use a streaming device like a Roku, Fire Stick, or Apple TV instead.

Clear the YouTube app's cache and data

The app stores temporary files called cache to load faster. If these files become corrupted, the app may crash or refuse to play video. Clearing the cache removes these files without deleting your sign-in information or watch history.

On most Android TV models, go to Settings, then Apps, find YouTube, select Storage, and choose Clear Cache. If that does not work, select Clear Data instead — this removes everything, including your sign-in, so you will need to sign back in afterward. On Samsung and LG TVs, the path is slightly different: go to Settings, Apps, YouTube, then Storage, and select Clear Cache or Clear Data.

Restart the app after clearing the cache. If YouTube still does not work, restart your TV as well.

Sign out and sign back in to your Google account

YouTube requires a valid Google account sign-in. If your account has a hold on it, if you changed your password recently, or if you are signed in to the wrong account, YouTube may not load or play video. Open YouTube, go to your account menu, and select Sign Out. Then sign back in using your full email address and password.

If you do not remember your password, use a phone or computer to go to accounts.google.com, select Forgot Password, and follow the steps to reset it. Once you have reset your password, sign in on your TV using the new password. If you have multiple Google accounts, make sure you are signing in to the one you use for YouTube.

Check for error codes and search for them

If YouTube shows an error code — a number or code like "400", "500", "tvq-st-101", or "tvq-pb-101" — write it down exactly. Search Google for the error code along with your TV brand, for example "tvq-st-101 Samsung TV". The search results will usually point to the specific problem and the steps to fix it.

Common error codes point to problems like account restrictions, region blocks, or issues with the YouTube servers themselves. If the error code search does not return a clear answer, try clearing the app's cache and data again, then restart your TV. If the same error code appears after a restart, the problem may be on YouTube's end, and you may need to wait for YouTube to fix it.

Frequently Asked Questions

Why does YouTube work on my phone but not on my TV?

Your phone and TV may be on different Wi-Fi networks or your TV may have a weaker connection. Check that your TV is connected to the same network as your phone. If both are on the same network, restart your TV and router. If YouTube still does not work on the TV, the TV's app may be outdated or the TV may no longer be supported by the current version of YouTube.

What does it mean when YouTube loads but video will not play?

This usually means the app's temporary files are corrupted or your account has a sign-in problem. Clear the app's cache first. If that does not work, sign out and sign back in to your Google account. If video still will not play, restart your TV and try again.

Can I use a streaming device if YouTube does not work on my TV?

Yes. If your TV is too old to run the current version of YouTube, you can connect a Roku, Fire Stick, Apple TV, or Chromecast to an HDMI port on your TV and use YouTube through that device instead. These devices are usually less expensive than replacing your TV.

Why does YouTube keep crashing when I try to open it?

The app's cache or data may be corrupted, or the app version may be outdated. Clear the app's cache first, then restart your TV. If it still crashes, update the YouTube app through your TV's app store. If no update is available, uninstall YouTube and reinstall it from the app store.

Does YouTube work without signing in?

YouTube allows you to watch some videos without signing in, but many features require a Google account. If you are not signed in, sign in using your email and password. If you do not have a Google account, you can create one for free at accounts.google.com.
