"just don't connect it to the internet" is such a typical HN response that completely misses the point. A smart TV with no internet connection is still a smart TV. It still has an entire operating system that needs to load wifi, ethernet, Bluetooth, usb driver stacks. It still has an awful, flashy interface that adds unnecessary steps between changing inputs. It still tries to load god knows what apps every time you…
meh, i think your response is more 'typical HN'. Nether are more correct than the other, but if you're annoyed or distrustful of all the internet connected factors of a TV, just don't connect it to the internet. I think that's a fine non-perfect, pragmatic solution.
Smart TVs never really turn off. If they did, they would take too long to "boot up" and consumers would be frustrated and angry. They're more like a laptop in a not-too-deep sleep state when they're turned off. Another commenter mentioned their smart TV consumes 10-20W when turned "off". That's just gross. It should consume milliwatts, at most.
And yes, I know that there are things in my house that consume far more power. But I actually get something for that power. A smart TV that I will of course never connect to the internet gives me nothing for that waste while in standby mode.
