Suggestions
Adverse conditions on the power connection (such as lightning or a power surge)
may have triggered the machine's internal safety mechanisms. Turn the machine off
and unplug the power cord. Wait for ten minutes, then plug in the power cord and turn
the machine on.
If the problem is not solved, turn off the machine. If you are using a power breaker,
disconnect it to make sure it is not the problem. Plug the machine's power cord
directly into a different known working wall electrical socket and turn on the machine.
If there is still no power, try a different power cable.
