After trying several options, your camera still will not turn on.

Check the power button on the top of the camera before beginning more in-depth solutions. The power button should have a red light next to it when on. Click the button and hold down if necessary.

If your camera won't turn on, check that the battery is charged. If the battery will not charge, you will have to order a replacement battery.

The guide for Battery charging and changing can be found in the following link: Charging the Battery and Battery Removal.

When trying to take a picture with your camera, "Lens Error" flashes across the screen and the camera will only show a black screen.

It is possible that something as small as a grain of sand could be preventing the lens from opening properly. Swipe the cloth gently across the lens to remove any debris.

Sometimes the lens is out of position and can no longer open or close properly. Look for a gap between the lens and where the lens retracts into the camera. Using your finger, apply gentle pressure to this area in a rotating motion until you hear a click, indicating the lens has moved back into place.

The guide for correcting a lens error can be found in the following link: Camera Lens Error.

Your camera could be in the wrong mode. Check to make sure you are in shooting mode and not playback or panoramic mode.

If this is the case the flash will need to be replaced. Please see the following link for further instructions : Flash.

A replacement bulb can be found either on Amazon or Ebay.
