If the machine is turned ON but does not respond, turn it OFF, check whether the power cord is connected correctly, and turn it back ON.
Unplug the power cord from the outlet and the machine, and plug it again.
Unplug the power cord from the outlet, and plug it into another outlet.
Check whether power is supplied through the power cord. Replace the power cord with another, or use a voltmeter to check whether the cord is not broken.

Has the machine just been turned ON?

Wait a while until the machine starts up.

Are all the cables connected correctly?

Check whether these cables are connected correctly. Use care not to mix up cable ports.

Is sleep mode activated?
