Difficulties Suggestions
The machine will not turn on. 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 you still cannot turn on the machine, plug the power cord directly into a different
known working wall outlet (do not plug it into a surge suppressor or backup battery
type of device), and then turn on the machine. If this works, then the wall outlet,
battery backup device, or surge suppressor device is the cause of the problem.
