This is probably THE most common failure among digital cameras. There's a halfway chance of fixing it yourself, described here: http://camerarepair.blogspot.com/2007/12/fixing-lens-error-on-digital-camera.html

Put in fresh batteries in your camera and try to power on. If this didn't work, do this little trick:

1. Hold the camera on your right hand with the lens facing the ground.

2. As you press the power on button, tap or hit the camera's base to your left palm. Do this several times.

Chances are, there could be a sand or granule of dust that got stuck on the sides of the lens, preventing it to retract properly.
