What to Do When Casting to a TV Is Not Working

Troubleshoot a phone or computer that cannot find or connect to a casting device.

Quick Answer

Confirm both devices are on compatible network segments, restart them, and check app/device permissions and updates.

Step by Step

  1. Check power, cables, network connection, and the currently selected input/account before changing advanced settings.
  2. Confirm both devices are on compatible network segments, restart them, and check app/device permissions and updates.
  3. Test the device after each change so you know what resolved the problem.
  4. Use factory reset or removing/re-adding a smart-home device only after simpler troubleshooting fails.

If That Doesn't Work

  • Menu names and capabilities vary by TV, streaming device, smart-home ecosystem, manufacturer, and model.
  • Smart-home devices can depend on Wi-Fi, hubs, cloud services, Thread/Matter controllers, and account integrations; determine which layer is failing before resetting the accessory.
