The lcd screen is held in place by a metal bracket, which usually has 2 or 3 screws to secure it to the main circuit board. Remove these with a jeweler's screwdriver, and gently lift the lcd and the bracket up out of the holder. The next step is to disconnect the ribbon connector by gently liting the plastic connector bar holder up, releasing the ribbon. There is always one wide connector, and sometimes a narrow one for the backlight. Installation is the reverse. You can install the battery at this point and check to make sure the screen is functioning. There are some videos about this procedure on YouTube, and if you search for "Samsung S85 lcd screen replacement" you may find one specific to your camera, but you can do a more general search for "lcd screen replacement", and find some videos that might help you see the process.
You're almost there...just carefully look for the holding screws on the metal holding bracket.
Here is a link to a procedure for one of the more difficult ribbon connectors, on a Canon Powershot, but the process is similar, and hopefully will give you the information to complete this task.
