A method for shutting off a projector having a fan and a light source is provided. The method includes the following steps. The power of the light source is reduced from a first power to a second power and the speed of the fan is increased from a first speed to a second speed after the projector receiving a first command. Then, a process is executed for shutting off the light source and the fan after the projector receiving a second command. The above-mentioned method is capable of not only preventing the projector from damage result from over-shooting, but also shortening the time needed to shut off the projector.
