    Re: dell E173Fpf

    I checked

    the line fuse F850 - OK
    line rectifier D850 OK
    capacitor C854 OK
    D854 OK
    MOSFET Q850 looks ok, no sign of burnt or cracked
    I check the diodes, nothing shorted or open.
    i also check resistors, nothing shorted or open
    Cap(s) are ok nothing looks blown up

    Which one is the PWM IC? how to check it?
    What else could be the problem?
    Also I have the power supply picture here

    Thanks
