Hi there,
Thank you for reaching out to our community.
I’m sorry to hear that your Google Chromecast (3rd Gen) began to flash on pink and red colors. Thank you for letting us know the troubleshooting steps you have tried to resolve the inconvenience to better understand your situation and provide you with better assistance. No worries, it is my pleasure to help you to find the best solution.
Before I start further troubleshooting, let me ask you a few questions:
- Could you please confirm what the model of your Chromecast device is?
- Have you tried using your Chromecast on a different TV? Does it show the same behavior?
- What is the distance between your Chromecast and the router?
- Is your Chromecast linked to a 2.4 or 5 GHz WiFi network?
- Could you please check if there are wireless interferences like walls and floors, nearby Wi-Fi networks, other electronics, cordless phones, baby monitors, microwaves, Bluetooth devices, and wireless video equipment?
- Did you receive any error messages in the Google Home app after performing the factory reset and trying to set up your Chromecast?
- Have you tried connecting the Chromecast to a different power source?
- Have there been any recent changes to your environment, such as a change in Wi-Fi network, recent outages, adding more WiFi devices, etc?
Thanks for your kind attention; I will be looking forward to your answer.
Best regards,
Virna
