With the front side (with the lens) facing up towards you, start at the bottom of the camera and gently pull off the front of the casing.
The nob that previously held the camera strap will no longer be attached to the camera once you remove the camera casing. When putting the camera back together, remember to put the nob back into position before replacing the casing.
Flip the camera over to the side with the LCD screen.
Gently remove the plastic cover that borders the LCD screen starting with the top left corner, then the bottom left corner, and finally the bottom and top right corners.
The LCD screen is now loose from the camera; it should only be connected by a gold strip that attaches to the circuit board.
Using a soldering station and solder wick or other solder removing instrument, remove the solder holding the two wires of the LCD screen to the circuit board.
You have now completely removed your LCD screen. It can now be replaced or cleaned.
