The problem with your Nikon 5700 may be easily solved through troubleshooting.
Nikon released its Coolpix 5700 in 2002 as a premium point and shoot digital camera. At its time of release, the 5700 was at the top of the Coolpix line, boasting 5 megapixels, a maximum image resolution of 2560x1920 and shutter speeds of up to 1/4000 second. Though discontinued, the camera remains a popular find on the used digital market. If you have picked up a 5700 that has a few kinks in it, troubleshooting the camera may bring it back to fully functioning condition.
Instructions
1. Insert a fresh EN-EL1 type battery into your 5700. Close battery chamber door completely. Turn the camera's main power switch to the "On" position. The camera may not power on without these adjustments.
2. Remove lens cap, USB cable and audio/video cables that may be connected to the camera. The monitor display will not light when any of these are connected to the camera. Press the "Display" button on the back control panel of the camera.
3. Press the shutter release button on top of the camera. If it does not fire and result in a picture, check the available storage space on the memory card by switching to "Playback" mode. If it is full, delete unwanted pictures or purchase an additional memory card. Also, poor lighting may cause inability to focus and result in a shutter lock. Engage the flash by switching to "Auto" mode or move to an area with better lighting.
4. Evaluate the exposure of your resulting pictures. If they are underexposed, or too dark, switch to "S" (shutter-priority) mode and reduce shutter speed by turning the command dial. Alternatively, switch to "A" (aperture-priority) mode and reduce the f/-number. Both of these options allow more light into the camera. If your photos are overexposed, or too bright, increase your shutter speed or f/-number. Doing so will allow less light into the camera. You may also change your exposure compensation settings by pressing the small button labeled "+/-", located near the shutter button, and turning the command dial. This adds or subtracts up to two f-stops of exposure from your pictures.
5. Depress the shutter button half way before taking your photos. This engages the 5700's auto-focus option and is the best way to prevent blurry pictures. Also, increase shutter speed when shooting fast action to avoid blurring and streaking.
