Hi team
I have a 820-00165 board that came because it's not detected the SSD but apparently it had water damage, and someone else tried to cleaned it.
After quick inspection: corrosion around U7600 and R7611 went out of its pace just when I touched it with my twizers so I replaced it.
At U3740:
pin 1 PP3v42_G3H: 3.447V
pin 2 P3v3SSD_VMON: 1.008V
pin 3 SSD_RESET_L : 3.291V
pin 4 SSD_RESET_CONN_L : 3.451V
pin 5 0V
pin 6 SSD_PWR_EN: 3,254V
pin 7 SSD_CLKREQ_CONN_L: 3,302V
pin 8SSD_CLKREQ_: 3,288V
It's NOT booting with another known good SSD but it is booting on OSX on USB/ external storage, and it's not seeing the SSD in Disk Utility.
Checked C3710 to C3717 all seems OK.
CLK100M_SSD oscillation is present.
