Hi,
Got this board with water damage U1900 and ISL area.
U1900 was replaced and now i get PVRTC_G3H 3,42V.
ISL also was replaced. Magsafe has light.
Now have this reails:
PPBUS is ok
ALL S5 and S4 reails are ok, except PP3V3_SUS and PP5V_S4RS3 ( It's generated from U8050 that doesnt recieve SMC_SENSOR_PWR_EN, it's just pulsing from 0 to 3.4 every 2-3 seconds.V)
Do you think it's SMC ?
P.S: SOrry. PP3V3_SUS is present and all sys pwr is pulsing every 2-3 seconds.
Already checked u1900 again and it seems be ok.
Also checked SMC bypass and fan spins for half second and stops.
