Use Settings → My Fire TV → Restart, or the supported remote-button restart method for the model.
Step by Step
- Check power, cables, network connection, and the currently selected input/account before changing advanced settings.
- Use Settings → My Fire TV → Restart, or the supported remote-button restart method for the model.
- Test the device after each change so you know what resolved the problem.
- 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.
