      If your BenQ Projector isn't turning on, there are a couple of things you can check. First, ensure the power cord is properly plugged into both the projector's AC power jack and the power outlet, and that the outlet is switched on if it has a switch. Second, if you've recently turned the projector off, wait until the cooling down process has completed before attempting to turn it on again.
