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.
