Why do I get audio from my TV when it's turned off?

Episode 1565 (1:38:33)

Max from Boca Raton, FL
Vizio D Series TV

Max is having issues with his TV speakers on his Vizio D series TV. He keeps hearing audio coming out, even when it's off. Leo says that today's modern TVs don't really turn off anymore. They just go into a very low power mode. Leo suspects that Max's Xfinity cable box woke his TV up through HDMI. Leo recommends putting the Vizio into Eco mode and it will turn off. Then, he should turn off CEC in his TV settings.
