Hi everyone ;-)
I have a MacBook Air A1466 that doesn't detect the SSD. I tried different hard disks but unfortunately the result did not change, at startup you see the apple logo for an instant and then move on, after about a second, to the flashing folder with a question mark.
I took measurements at U3740 and the following measurements were made:
R3741 pin1 3.3v pin2 1v;
the other voltages seem regular, I measured in diode mode and there don't seem to be any strange values, I noticed something strange, that is, without the SSD connected I have 3.3V at pin 8 (SSD_CLKREQ_L), when I connect the SSD the voltage drops to 0V...
I checked the schematic and this connection goes directly to pin 24 of the ssd connector, which when measured at no load in diode mode gives a normal value.
I'm trying to understand but I'm stuck......what else could I try?
