Sony's Cyber-shot line of digital cameras gives users access to an array of helpful features, such as a zoom lens, auto-focus and scene selection modes. Although the Cyber-shot's flash is generally on by default, you may have accidentally turned it off when taking a picture or transporting the camera. The flash is necessary if you are trying to take photographs in low light environments or at night. It can be turned back on with the press of a button.
Power on the Sony Cyber-shot camera by pressing its "Power" button. In most models, this is a small button located on top of the camera.
Locate the "Flash" button. This button is generally the top one on the four-button circular control panel. A small, jagged arrow line is printed on it that resembles lightning.
Press the button several times to get the desired flash mode. Watch the camera's screen as you do this so you know what mode you have selected. If the arrow symbol is visible on the screen, the flash is forced on, and it is used every time a picture is taken. The flash will go off, for instance, even if it is light outside.
Press the "Flash" button until there is no indicator on the screen to set the flash at its default setting. This causes the flash to go off only when the camera detects low light levels.
Push the "Flash" button until the symbol appears on the screen with an "SL" next to it for Slow Synchro mode. This reduces the shutter speed, letting the flash shoot a darkened background more clearly.
Tap the "Flash" button until a crossed-out arrow symbol appears. This means that the flash is forced off and will not be used for any type of photo.
