Konica Minolta Dimage 7i loose lens

We have dropped our camera, and although it works fine in widescreen mode the lens is loose and when you extend the lens it moves around freely. When it is restricted there is no problem and it takes acceptable pictures. We have tried to open the camera up to reseat the lens but dont really want it to ping all over the place. Does anyone have a manual so that we can undo it successfully.
Many thanks
