Auto power off
The TV will automatically turn off after approximately 15 minutes if it is tuned to a vacant channel or a station that completes its broadcast for the day and stops broadcasting on that channel. This feature does not work in video input mode.
Understanding the Power Return feature
If the power is cut off while you are viewing the TV and the power is resupplied, the Power Return feature will turn the TV on automatically.
If the power is going to be off for a long time or you are going to be away from the TV for a long time, unplug the power cord from the wall outlet to prevent the TV from turning on in your absence.
