    820-01700 5V 0Amp liquid

    i have change the PMIC for 820-01700. I have 5V 0,050A now. short is remove, I have PPBUS_G3H=12V I have PP1V8_SLPS2R short too, when I inject 1V I have T2 chip become hot, can I replace it? I think 'no' 🙃 thanks

    Hi, i have this board liquid spill U7800 is short on signal PP3V3_G3H_SOCPMU. i remove the component short is remove, but is in the component. Can I change it to keep on donor board? thanks Best regards

    820-00850 5V 36ma no liquid, no DFU

    ok thanks, I change U7800 and now the PP3V3_G3H is stable. the pin 277 under U7800 was burn. now work well, thanks

    12=0V 13=0V 21=0V 22=3,293V fix 23=12,29V fix 29=0v i remove L7660 to see if P3V3_G3H is stable but always same (not fix)

    Hi, this board 820-00850 is lock to 5V 36ma (no liquid spill, no DFU). i have PPBUS = 12,29V, PP3V3_G3H = 2,5V to 3,3V no fix. i inspect the board in microscope, I don't see a short. Big coil seems ok except L7270= 0,010 & L8102=0,065 in diode mode can you help me please? thanks

    Hi, yes, when I push the button power, PM_PWRBTN_L fall.

    PM_SLP_S4_L = 0 and when I put SMC_ONOFF_L short to GND, I haven't pulses on PM_SLP_S4_L.
