YouTube not working on your TV? How to fix it
When the YouTube app on a TV will not open, plays a black screen, or crashes back to the home screen, the cause is almost always the app or the connection, not the television. Work through these in order. The last one matters if your TV is a few years old, because YouTube does drop support for older sets.
Restart the app and the network
Close YouTube fully and reopen it, rather than just returning to the home screen. Then power-cycle the network: Unplug the router and the TV for a minute, bring the router back first, then the TV. This clears a stalled connection and a stuck app in one go, and it is the fix more often than anything fancier.
Update or reinstall the app
An out-of-date YouTube app is a common cause, because the service keeps changing and older versions stop working. Check your TV's app store for an update, and if there is none, remove the YouTube app and reinstall it. That clears a corrupted cache and installs the current version at the same time, which fixes most black screens and crashes.
Check the date and time
This is the surprising one. If the TV's clock is wrong, the secure connection YouTube needs can fail, so the app loads to a black screen or refuses to sign in. Open the system settings and set the date and time to automatic, so the TV gets the correct time from the network. It is a two-second change that fixes a problem people chase for hours.
Test the connection
If YouTube opens but stalls or drops quality, it is the connection. Our TV Speed Test measures the real speed reaching the television, and if it is low the fix is the same as for any streaming: A stronger Wi-Fi signal or a wired cable. Our guide on why a TV keeps buffering works through it in full.
If your TV is older
Here is the honest part. YouTube periodically ends support for older TV models and operating systems, and when it does, the app stops working for good and no update brings it back. If your set is several years old and nothing above helps, this is the likely reason. The cheap, reliable fix is a streaming stick, a Roku, Amazon Fire TV Stick, Google Chromecast or Apple TV, which plugs into an HDMI port and runs a fresh, supported YouTube app on any TV. Our What TV Do I Have test shows roughly which generation your set belongs to.
Questions people ask
Why has YouTube stopped working on my TV?
Most often the app is out of date or its cache is corrupted, so reinstalling it fixes it. A wrong clock on the TV can also break the secure connection YouTube needs, so set the date and time to automatic. If the TV is several years old, YouTube may have ended support for it, and a streaming stick is the cure.
How do I reinstall the YouTube app on a Smart TV?
Open your TV's app store, remove the YouTube app, then download it again. On most TVs this clears the old cache and installs the current version in one step, which fixes black screens and crashes that a simple restart does not.
Why does YouTube say my TV is no longer supported?
YouTube ends support for older TV models and operating systems over time, and once it does the built-in app stops working and cannot be restored. The simplest fix is a cheap streaming stick, such as a Roku, Fire TV, Chromecast or Apple TV, which runs a current YouTube app on any television.
If other apps also stall or drop out, the problem is the network, not YouTube: See why does my TV keep buffering, and confirm the speed reaching the set with the TV Speed Test.
