    I'm trying to repair an appliance for hair removal that uses a xenon lamp. (see attached)
    Such devices called IPL, activate and deactivate the capacitors to discharge at predetermined time intervals, in order to have an effect of the pulsed light flashes and available energy in the shortest time.
    I made the schematic but I can not understand the function of some signals, because the microprocessor control board is broken!

    Is just the functioning of PIN16 - PIN20 connector CONN1 ? (see attached diagram)

    here is the translation of the PIN in the wiring diagram:

    PIN16 = active download trigger transformer for triggering
    PIN17 = ???
    PIN18 = active discharge capacitors
    PIN19 = PWM to adjust the charge of the capacitors
    PIN20 = active charging capacitors

    I don't understand the PIN17 function yet. Could you tell me more details about it?
