When small square "PHOTO" pcb is disconnected from "09830-66565" (main board), values are:
- 8.9K (completely dark - entire transport covered)
- 0.29K (straight and intense light beam from phone LED)

Same values in the soldering place (shown on before photo), and between 3 and 9 pins of the "PHOTO" pcb
