Hi Smarttvuser,
Thanks for reaching out to our community.
I’m sorry to hear that you're experiencing trouble casting to your primary TV, but you receive a message suggesting that you could cast to another TV in your house. Thank you for adding important information such as the other TV uses an older version of Chromecast that is separately connected. No worries, help is here.
Before we proceed with further troubleshooting, let me ask you a few important questions:
- When did the issue start?
- Could you please confirm what the model of your Chromecast streaming device is? Here is a Google help center article that can help you to identify your device: Chromecast and Google TV Streamer specifications.
- Are you using an Android or iPhone device to set it up?
- Is your Google Home app updated?
- Is your mobile device connected to the same WiFi network as your Chromecast streaming device?
- What's the Chromecast streaming device firmware version? You can use this Google help center article as a reference: Find your device’s firmware version.
- How far from the router is your Chromecast streaming device?
- Can you describe the status of the Chromecast streaming device LED light?
