Before you switch on the TV, make sure you plugged in the mains power in the POWER connector on the back of the TV.
To switch the TV to standby, press on the remote control. You can also press the small joystick key on the bottom of the TV.
In standby mode, the TV is still connected to the mains power but consumes very little energy.
To switch off the TV completely, disconnect the power plug.
When disconnecting the power plug, always pull the power plug, never the cord. Ensure that you have full access to the power plug, power cord and outlet socket at all times.
