Voltage of Power suply output and of DC-DC board
do someone know the Voltage of the output from power suply (black = 0, grau = 12V ? , brown = ? )
and the output from the DC - DC board?
forget the power supply right now, check the dc/dc board, if you don't have the proper voltages there then ck the power supply.
looking straight into the dc/dc female plug...
onA - Grd-12vR -(?) -5.0vR -3.3vR
(?) - 12v - 12v - 5.0v - onB - 3.3v
the ? pins are probably grounds as well, but I'm not 100% sure - the 'R' voltages are only on when the power A and B pins are touched together ie. the computer is on
