Hi TC12,
Thanks for posting here in the Google Nest Community. Kindly help us by providing more details so we can share accurate answers to your questions. Let’s start with your device. What Chromecast device do you have connected to your TV? What is the make and model of your TV? Are you trying to set it up for the first time? If yes, is this the code being asked similar to what shows on your Google Home App? If this is already setup, then this code on the TV must be related to what you’re trying to cast. What app are you trying to cast? What steps have you taken?
We look forward to your response.
Thanks,
Kimy
