How to reset the Google Chromecast with Google TV
You want to factory‑reset the Chromecast because of persistent problems or before giving it away.
We could not fully consult the manufacturer's support page for this model; the steps are general and may differ in details.
Most likely causes
A full reset is needed for persistent connection or setup failures
- Warning: a factory reset erases local settings and device links; you will need to set up the Chromecast again in Google Home.
- Press and hold the button on the Chromecast (usually on the side or underside) until the LED blinks and the TV screen changes.
- Release the button when the LED flashes rapidly and wait for the Chromecast to restart.
- Signal: you see the welcome screen and Google Home detects it as a new device.
Reset didn't work or device is unresponsive
- Unplug the power for 30 seconds, plug it back in and try the reset button again.
- Try a different power adapter and cable if available, since low power can prevent a proper reset.
- Signal: the Chromecast restarts and responds to the reset procedure.
Frequently asked
My phone can't find the Chromecast during setup. What should I do?
Make sure your phone is on the same wifi you plan to use, and that Bluetooth and location services are enabled; restart the Google Home app and try again.
Should I use 2.4 GHz or 5 GHz wifi?
If your router uses separate names, try 2.4 GHz first; it can be more reliable during initial setup for some devices.
Will my purchased apps be lost after a reset?
Apps and purchases tied to your Google account remain, but the Chromecast loses all its settings and must be reconfigured.
Chromecast shows offline but TV has picture — why?
Reboot the router and Chromecast, then check in Google Home whether the device still uses the same wifi network.
