Can't you just tell it to automatically switch to some HDMI input on power on?
I have one of those "smart" TCL TVs, with Google TV. No idea what the difference is with Android. I've tried using the smarts, and it was a shitshow, even brand new. Laggy as hell.
Fortunately, it has an option to turn on to the last used input. It's also possible to turn on and off by receiving some signal from an external device over HDMI. I basically never touch its remote anymore and the only reminder that it runs "Google TV" is the logo when it turns on. It's unplugged from any network, and the only consequence is a notification which disappears on its own that it's not connected to any network.
