An investigation by Gamers Nexus found LG smart TVs sweep local networks to map phones and nearby devices. Tests also showed the sets can capture microphone audio with the screen off — they then upload data once reconnected to the internet.

I'm not surprised. Almost everything that you would assume does something in only one direction also does it in the other direction. LEDs generate a small amount of current when you shine a light on them, solar panels emit a small amount of infrared when you apply power to them, etc.

To be fair to solar panels, isn't about everything emitting infrared if you apply power to it? :x
