Everything seems to be ok with my oscilloscopes (I have two). I would consider it finished if I didn't have found a different voltage reading from the Assembly Guide. I find V5 (near JP9) at -3,3V or +3,5V (depending at the positions of sw1, sw2 and sw3), not "approximated 1,6V" (in both oscilloscopes). I already checked the resistors and voltages and everything else seems ok. What should I do?

V4 is supposed to be 1.6v I believe, If it is not R12 is probably a 10K resistor not 120. It's very hard to tell them apart by colors. I know because I messed them up myself. Once fixed I started getting a signal.
