If your BenQ Projector doesn't turn on, first ensure that the power cord is correctly plugged into the AC power jack on the projector and the power outlet. If the outlet has a switch, make sure it is switched on. Also, if you've recently turned the projector off, wait until the cooling down process has completed before attempting to turn it on again.
