  If your BenQ Projector is not turning on, it could be due to the following reasons: * There's no power from the power cord. Make sure the power cord is plugged into the AC power jack on the projector and into a working power outlet. If the power outlet has a switch, ensure it is switched on. * You're attempting to turn the projector on again during the cooling process. Wait until the cooling down process has completed.
