SOLVED: A1466 820-00165 Not detecting SSD. Tried with multiple SSDs.

[it-solve]

No Liquid damage, slight oxidation around C2441 RP2712
Loads externally, stable. Only SSD not detected.

SSD_PWR_EN = 3.25V
SSD_RESET_L= 3.30V
PP3V3_S0SW_SSD = 0.4V
P3V3SSD_VMON = 0.12V


U5480 diode measurements seems ok
U3710 diode measurements seems ok
Tried multiple SSDs and SMC reset. Can boot from external SSD, no internal is detected.

"PP3V3_S0SW_SSD = 0.4V"
Diode mode to ground?

Inspect U8070 area...

Thanks again. Seems like it was a faulty U8070, although diode measurements were ok
