    • The large cylindrical object on the right side of the board is the flash capacitor.

    • WARNING: The flash capacitor may carry high voltage, that may persist for hours or even days after the camera has been switched off and/or the battery has been removed.

    • Touching the circuit board while the capacitor still holds its charge may result in a painful electric shock that you will long remember.

    • To make the board safe to work on, short out the two marked terminals with a capacitor discharge tool or the blade of a screwdriver or similar implement (with an insulated handle!) You might have to use moderate pressure to punch through the white goop that covers one of the terminals.

    • There might be little sparks and/or an audible pop. Be careful not to short other solder connections nearby.

    • Use a multimeter to check that dangerous voltage is no longer present before you proceed.

    • Unsolder all of the wires on the top of the logic board.
