Hi, I have this 820-00840-A board with liquid damage around U7650 and the backlight stuff also.
I've narrowed it down to U7650 not creating PP5V_S5 and that's due to PMIC_EN_P3V3S5 missing.
So, checking around PMIC, I could see that PP3V1_RTC is good, PP3V3_LDO3V is good, PP1V25_VREF is good.
PMIC_SHUTDOWN_L is high.
On this board, R7828 is the one present.
What should I check next ?
