What to do if Chromecast won't appear on TV?

If your Chromecast isn't appearing on your TV, first ensure that it is properly connected to the HDMI port and that the TV is set to the correct input source. Check that both the Chromecast and your mobile device or computer are connected to the same Wi-Fi network. Restart your Chromecast by unplugging it from the power source and plugging it back in. If the problem persists, try resetting the Chromecast by holding down the button on the device until the LED blinks orange, then release it.
