If the power indicator does not turn on when the power cord is plugged in, you
may have a problem with the power outlet, power cord, or internal power
supply. However, if the unit powers off after running for a while, check for loose
power connections, power losses, or surges at the power outlet. If you still
cannot isolate the problem, the internal power supply may be defective.
