  • Detach the printed wiring circuit board by gently pulling it away from the back cover. Because the screws have already been removed, the circuit board should come apart easily; it is now attached to the back cover by two thin red and black wires. Two blue and pink colored wires connect the circuit board to a small circular capacitor.

  • Use a pair of thin tweezers to carefully pry the rectangular display plate from the front casing. Slide one of the sharp ends of the tweezers between the display plate and the plastic case and lightly apply pressure until the plate pops out. The display plate will still be attached to the circuit board by a single strip of orange wire tape.
