A user reports that a projector was previously working, but the screen now displays the following error message: No Source Found. Which of the following actions should the technician take first? (Select two).

While a burnt-out bulb can cause display issues, this is not the first action to take when encountering a "No Source Found" error. The projector may still be functioning but simply not receiving a signal, making it more logical to verify power and input settings first.

Replacing the video cable is a reasonable troubleshooting step; however, it should not be the first action taken. If the projector is not powered on or set to the correct input, changing the cable would not resolve the issue. It's essential to verify the power and input settings first.

Adjusting laptop display settings may be necessary, but this step is contingent upon ensuring that the projector is turned on and set to the correct input source. If the projector is off or configured incorrectly, the laptop settings alone will not solve the problem.

While ensuring the correct resolution is important for compatibility between devices, it is not the first step when the projector shows "No Source Found." Like other actions, it relies on the projector being powered on and correctly set to receive a signal.
