Thanks for posting in the community. I'm sorry to hear your Chromecast (3rd gen) works for 10 seconds when it turns on before the screen goes black with an orange light. Help is here!
To address the issue, please try these steps:
Test the power source: Unplug your Chromecast and plug another device into the same outlet to ensure it's working.
Use the original power adapter: Make sure you're using the power adapter and cord that came with your Chromecast.
Factory Reset: If restarting doesn't resolve the issue, a factory reset may be necessary. This will erase your data and cannot be undone. Refer to this article: How to factory reset your Chromecast.
