Note that the 6 pin (sot23-6?) device has a few pcb pads missing off the pcb.

On the main siding 3 pin sot23 device, probably K72 but share the other parts markings nearby. K72 = 2n7002.

You forgot do do your homework or do you expect us being some sort of magicians?

Iirc schematics are actually available for this board so you have nothing more to do than to follow the tracks to known or at least unambiguously points till you find a connection which fits. With the multimeter of course.

Without some effort from your side we cannot help you at all.
