The first thing to do is draw the circuit diagram from the PC board.
We cannot do anything more until we know how the resistors are connected.

You need to put a baffle between each receiver and turn on one of the LEDs and place the project near a piece of paper with a thick black line.
Measure the voltage on the output of the photo diodes as the project is brought near the line.
