TV Powers “on” & “off” by itself

Topic issue troubleshooting FAQ

Does it happen every day around the same time?
If yes, then perhaps someone in the household inadvertently set the TV timer “on”
Home > Time > verify whether On Time or Off Time or both are set to “ON”
Highlight On Time > ENTER > select “OFF” in the Repeat field > ENTER
If this is not the reason and the TV turns itself “on” & “off” randomly anytime of the day a service technician will need to have a look at the problematic unit.

LG H D M I C E C SimpLink definition - If there are many peripheral devices connected to the television making use of all HDMI ports, should any of those devices somehow wake up from their sleep mode even very temporarily and the television's SimpLink (HDMI -CEC) enabled, there is a good chance the device will inadvertently produce a command for the TV to power 'on' if 'off' or vice versa. It might be wise to disable the SimpLink feature on the LG television to avoid any intermittent powering on/off.
