HDMI CEC is full enabled and all functions work, expect that the LG TV won't turn off. It turn on, and I can control the Mi Stick over LG RC but once I turn the Mi Stick off, TV will stay on with "no signal". (I don't know the exact model of the TV.)
Same issue here using an LG TV and Mi Box S. Never found a fix to have the box turn off the TV but turning off the TV first will turn off the box
