Chromecast turns on / off itself

[JPaulo]

Hi.
Bought Chromecast 3 a few days ago and plugged into the TV USB and HDMI port. Now here's the story: When I finish watching a movie, I turn off the TV. 5 or 6 minutes later, Chromecast is also turned off.
Then 4 or 5 hours later Chromecast turns on itself. What does it all mean?

Hi JPaulo,

It sounds like the Chromecast is being underpowered, you should use the Google supplied power adapter as TV USB ports can be unstable.

No. Thank you.

Of course! In that case, I'll go ahead and lock up the thread. If you run into any more issues in the future, feel free to create a new thread. 

Thank you for your help, Cathal_S!

Best regards,
