Thanks for reaching out and I'm sorry to hear about that. I'd like to dig deeper into this.
Could you tell us more about what's going on with your device? What type of Chromecast with Google TV device do you have, is that the 4K or HD model? Is your Chromecast with Google TV no longer working? What's the LED status on your Chromecast with Google TV?
Also, could you please provide the following information below:
I'll look forward to your response.
