arc TV connection

Are you connected to the TV ARC/eARC?  Did you try running TV Setup in the app?

What does ‘discounted everything’ mean? 

If you didn't unplug everything from the power outlet go back and try that, two minutes is usually a safe time to leave things unplugged.

The on / standby button often fails to trigger a proper reset.

Probably “disconnected everything”?

Ah, yea, likely an autocorrect error. Oddly, my mind didn’t go there. Thanks!

Sometimes I think that the AI autocorrect agents get together in a chat and giggle about the things they have had people say in posts.
