There are more than one possibility for this scenario (settings, cable, lamp):

•The display is not set as the primary or active display (such as is the case when set to view in projector-only display mode). Many laptops have either a Function key (such as F4) or a hotkey expressly set aside for presentations (usually at the top right with two other hotkeys). Newer operating Windows systems allow for changing the display mode through holding a Windows key down while pressing the [P] key.

•The monitor data cable is damaged. Sometimes, this can be tested by changing the vertical angle of the display to see if the display shows. (In this case, replace the display data cable.)

•The lamp inside/behind/above/below the display could be going out. (In this case, replace the display lamp.)

The easiest way to test & to give a temporary workaround would be to hook an external monitor to the laptop & to turn on both devices to ascertain if the video output shows on it.

If all else fails, then take it to a technician because the system board could be bad.
