DP_INT_HPD 480-720
I2C_ALS/SDA 510-610 1.8v on both
PP5V_MAIN_ALSCAM 5v
water damage just on U9300 was replaced it and few the compnents around and few jumpers.
PPBUS 9-12v pulsing
all the voltage around U9300 pulsing 70%-95% off they corrent voltage.
charger 5v A pulsing A1.2-0.2
without battary:
PPBUS_G3H - 0.3v
3V3_G3H -3.4
with Battary:
