Hello,
while I can confirm that the bigger black with two pins is a diode, I'm not
sure what kind of diode it is, as it could be bipolar, Schottky or Zener.
About the smaller black components with three pins, they could be
transistor or diodes (single or double, with common cathode, common anode
or series).
I will try to find a correspondence for the markings, but symbols are
someone strange, so a clear macro picture would be better...
