Why won't my flash work when I take pictures?
The screen displays properly, the trigger button works, and the camera takes pictures, but the flash does not work when I take the picture.
The most common reason for the flash not discharging is that the flash is not turned on. The flash settings are located in the menu. For more detailed instructions for turning on the flash, consult the instruction manual.
Also, there are possible hardware malfunctions that will prevent the flash firing.
