Has the camera been dropped latley? have you taken it to the beech? these units have a telescopic lens mechanism and they use gears and motors to extend the lenses. If any debris gets in there it can jam up the gears. If it has bee dropped or bumped the mechnisim can bind and damage the gears or the moving parts that run this. Its very common and really hard to avoid. Some are very fragile. If the lenses are not extending when you try and power it on it may need serviced. There is a guy on e-bay who does some good cheap repairs named "Darntoothysam" he is a master sony repair guy who has been doing it a few years. Maybe contact him see what he thinks.
