Need help with this problem I got myself into. Replaced screen on MacBook. Was working fine with broken screen. Used a Chinese screen which have used before with no issues. Battery was unplugged and charger not connected.
Board will not take 20v now and won’t power on. Stuck at 5v and 0.06a
Took measurements around U5700
PPBUS_AON is 12v
PP5V_AON is 5v
P3V8AON_PVCC is 0v
P3V8AON_PWR_EN_R is 0v
PP3V8_AON is 0v
Around UF500
PP3V3_S2_LDO 0.8v
PP3V3_UPC1_LDO 3.4v
PP1V5_UPC1_LDO_CORE 1.5v
PP1V8_S2 0v
Not sure what to do, appreciate any help available.
Thank you.
