  If your BenQ Projector isn't turning on, there could be a few reasons. First, ensure the power cord is securely plugged into both the projector's AC inlet and a working power outlet, and that the power outlet switch is on. Second, if you've recently tried turning it on and it didn't work, the projector might be cooling down. Wait until the cooling process is complete before attempting to turn it on again.
