    Question: I have a loose component (1N4742A) inside my unit and I cannot find where it belongs, can you please help me find the location?


    Answer: The loose component is a diode that was added after production of the circuit board. As a result, there is not a physical location on the board to accommodate this component. The diode is soldered across component  C27 (10F 35V Capacitor) with the cathode (side with solid line) connected to the left side (assuming board is held right side up. See Photo below).
