  If your BenQ Projector isn't turning on, consider the following possibilities: * **Power Supply**: Ensure the power cord is securely plugged into both the projector's AC inlet and a functioning power outlet. If the outlet has a switch, make sure it's switched on. * **Cooling Process**: If you've recently turned the projector off, it might be in the cooling process. Wait until this process is complete before attempting to turn it on again.
