20 Ways to Fix Chromecast Not Working on Android TV
1. Restart Your Android TV
Restarting clears temporary software glitches affecting Chromecast.
- Turn off the TV.
- Unplug it from power.
- Wait 60 seconds.
- Reconnect the power.
- Turn the TV back on.
2. Restart Your Smartphone
If you are casting from an Android phone or tablet, restart the device before trying again.
3. Verify Both Devices Are on the Same Wi-Fi Network
Chromecast only works when the Android TV and the casting device are connected to the same Wi-Fi network.
4. Restart Your Wi-Fi Router
Power off the router, wait one minute, and turn it back on.
5. Enable Wi-Fi Instead of Mobile Data
Ensure your phone is connected to Wi-Fi and not relying solely on mobile data.
6. Check Internet Connectivity
Open YouTube or a website on both the TV and your phone to verify that both devices have internet access.
7. Update Android TV Software
- Settings
- Device Preferences
- About
- System Update
Install any available updates.
8. Update Google Home App
Install the latest version of the Google Home app from the Google Play Store on your phone.
9. Update Streaming Apps
Update apps such as YouTube, Netflix, Prime Video, Disney+, and others to improve casting compatibility.
10. Reboot the Chromecast Built-in Service
Restarting the TV usually refreshes the built-in Chromecast service.
11. Turn Off VPN Services
If either your TV or your phone is using a VPN, disable it temporarily and test Chromecast again.
12. Disable AP Isolation on the Router
Some routers include an AP Isolation or Client Isolation feature that prevents devices on the same Wi-Fi network from communicating with each other.
If enabled, disable this feature using your router's settings.
13. Clear Cache of Chromecast-Related Apps
- Settings
- Apps
- Select the affected app.
- Storage & Cache
- Clear Cache
14. Enable Network Discovery
Ensure your home network allows devices to discover each other. Some router settings may limit local network visibility.
15. Test Another Streaming App
If Chromecast fails only with one application, the problem may be with that app rather than the TV.
16. Try Screen Mirroring
Test casting by using Android's built-in screen mirroring feature. If screen mirroring works but app casting does not, the issue may be specific to the app.
17. Reset Network Settings
If your Android TV includes a network reset option, use it and reconnect to your Wi-Fi network.
18. Factory Reset Android TV
- Settings
- Device Preferences
- Reset
- Factory Data Reset
19. Factory Reset Your Router
If Chromecast has never worked correctly and other devices also experience network discovery issues, resetting the router may help. Reconfigure the router after resetting.
20. Contact the TV Manufacturer
If Chromecast Built-in still does not function after trying every solution, contact your TV manufacturer's support team for further assistance.
