Explanation

A 'No Source Found' error means the projector is not receiving a video signal from the connected device. The two most logical first steps are: verifying the projector's input source setting (B) to ensure it is set to the correct port (e.g., HDMI 1 vs. VGA), and setting the laptop's display output (D) to extend or duplicate so it actively sends video to the external port. These address the two most common causes of a missing signal. Replacing the bulb, video cable, or checking resolution are secondary steps taken only if the signal issue persists after confirming the correct input and display output are configured.
