When the camera gives this message it means it can't properly initialise the lens mechanism. The small servomotors can't properly align the zoom lens, either because they are stuck in something or because the assembly is damaged in some way. This problem will require service intervention as it is a delicate repair especially for the DSC-Wxx series. I have a W70 here for repairs, this mechanism is a very complicated and small. This errors occur because of shocks received by the camera (most often) or simply just like that, if a small part of the lens assembly just gets out of place.
The repair varies from simply having to realign the lens to situations where the whole lens mechanism must be changed. Ask the service man there to make you an estimate before he starts the actual repair.

Hello!

Same mechanism problem here on a DSC-W50. For me, it did not work out to PULL the lens, but to push them. I just opened the camera and it tried to calibrate the lens with no success for about 4 times, after it just let them out and displayed the "power off and on your camera" message. The problem is that on this model of camera when the lens is out you cannot push or pull it. So I thought of a trick: when the lens is moving, you can pull or push them. Anyway, this is what I did: with the lens out, i placed the camera with the lens towards a soft surface (bed) and gently pushed on the side with the display. First times it didn't work, so I had to push harder and finally it worked and now my lens is aligned and the camera is working as if it were new. I suggest you try to push or pull the lens while it is moving GENTLY at first, and if it does not work, try harder - really hard! It will do a click at some time and work fine!

Mine did the same thing, and after I read this, I decided to turn the camera on, and as the lens was extended, I gave it a couple of taps. It worked! Try not to hit it too hard though. Good luck!
