it sounds like you have damaged the focus mechanism and/or the CCD... the equivalent of the negative/film in an old style camera. You will need to replace this or try opening the camera and check the flex from the lens and CCD have not come loose. Oldturkey has quite a few repair/service manuals and he may have one for this camera to help you out.
