820-2936 board. I dont have another board do swap and customer want to fix the thunderbolt.
I have 0.5V at D3895 pin 1,2 and 0.582 diode mode after and 0.532 before- D3895
T29_A_HV_EN_R - 0V so I miss enable. I tested with thunderbolt connected with good known hdd with OS X.
Could be bad U3890? I am confused as I miss enable - T29_A_HV_EN_R so I dont know what to check next.
