My lens is not going in or coming out in sony w5

When I turn the camera on, only a partial screen is coming up. The top half of the words "Cyber-shot" is showing. The camera makes a turn-on sound (dings). The "Menu" button does nothing. The buttons in the "control" area make a bleep when pushing them, but nothing happens. Turning the top that controls the picture settings including "looking at last picture" and "video" does not do anything. When I hit the power switch to turn it off, the "on light" goes off, but the camera does not turn off. I have to open the battery compartment to shut it off. The batteries have been removed and charged. The memory stick has been taken out (and put back in) and does not make a different. The camera has not been dropped or abused. One day when I turned it on, the above were the results. Any advice would be appreciated. I tried the seven steps that someone suggested, to no avail.
