First of all, go to radio shack and get yourself a set of precision screwdrivers. Get good ones since you need good grip here, as the screws will be really tight. Remove the battery from the camera. Now lets unscrew it, literally. There are 4 pairs of screws in total - 2 pairs on the bottom, 2 pairs on each side. The side screws become visible once you open the compartments for the batteries and the compartment for the DC power.
Ok, now that you removed the 8 screws, snap-out the plastic cover on the side where the DC input is. Then try to pull apart the two halves of the camera, the front cover from the back cover. One of the corners is kinda tricky, but just force it a little and it will snap open. Be careful but firm. Now you have the camera opened-up, it should look like this: You can now hook the camera to the outlet as the figure shows. Turn on the camera, and it should work as before. In my case, the shutter cover is stuck, so the lenses don't open or extend. Now notice that there are two switches that sense whether the shutter cover has retracted or not: In the case of my camera, I can fool it to extend the lenses by pressing the top left switch with a screwdriver:
