Reboot the computer connected to the projector to reset the video output.
Adjust the projector's brightness and contrast settings from the menu.
Replace the video cable connecting the projector to the source.
Inspect the projector bulb for visible damage or discoloration.
Noticing a faint smell similar to burning electronics when a projector fails to produce visible output is a strong indicator that the projector bulb has likely burned out.
