Identifying SMD's on circuit board

Regarding the PV label on the SMD transistors I refer to this page:
https://smd.yooneed.one/code5056.html You can see several interpretations for the PV mark and the casing style SOT-23 helps identify your SMD transistor type among them.

In your photo at the upper left circled area:

PCB label R32: 103 on the body of the SMD resistor means 10 kOhm
PCB label Q16: PV is a PNP switching transistor with built-in bias resistors, see data sheet:
https://datasheetspdf.com/datasheet/KRA226S.html or here in better quality:
https://datasheetspdf.com/pdf-file/787874/KEC/KRA226S/1
(manufacturer is Korea Electronics)

In the upper right hand circled area:
PCB label R33: 202 on the resistor body means 2 kOhm
PCB label R34: no resistor used, empty place
PCB label C12: should be an SMD capacitor but it is impossible to see its value

In the big middle circle: there are 3 transistors of the same PV type like above on the left.
The number 42 on the case of the transistors means the lot number given during manufacturing.

cheers
