A1534 820-00244-A don't work no image or DFU

i have this board :

PPBUS_G3H = 8,64v
PPBUS_S5_HS_COMPUTING_ISNS = 8,64V
PPVBUS_LIO = 20V
PP3V3R3V0_AON = 3,26V
PPVRTC_G3H = 3,05V
PP5V_G3H = 5v change 0v again 5v 1-2seconds
PP5V_S0 = 0V
PP3V3_S5 = 0V
PP3V3_S0 = 0V
PP3V3_SUS = 0V

any ideas? very thx !!

Check U7800's LDOs voltage (page 46).
If any missing, check in diode mode too.

all points with 3,26v and diode mode values 710/730 If you wish, I can compare it with a board that has a damaged SSD but turns on and work

"all points with 3,26v"
Really all?
LDO3V, VREF1V25, LDO5V.
