Hi
Got A1707 820-00928-04 stuck at 5V.
found little moisture around U3500 but did not find any damaged or shorted component.
UB300 and UB400 are providing stable 5V but U3100 and U3200 are fluctuating between 1.65 and 5V in every 6-7 seconds.
I have tried with known good controller but same issue. All the LDOs on both ICs are also fluctuating. PP3V3_G3H and SMC_RESET_L also fluctuating.
