hi guys
this board had alittle water damage
PQ33 and PD2 was damaged

i replace them,and now not charging the battery

when i plug the battery at first it hav 12.45V and use 0.02A
ENCHG# = 3V
CHARGE_CTRL = 0.7V

after some secends charge led start blinking in orange and battery voltage reduce to 0
ENCHG# =0v
CHARGE_CTRL = 0V

in sony manual said that it mean:A battery error has occurred due to a failed battery
pack or an unlocked battery pack

what do u think?

and a question
what is BATT_PRS# and SYS_PRS#???

It happens when damaged gates of charging mosfets or charger IC. Check short circuit between phase and gates of mosfets.

BATT_PRS# : will active(low) when battery is inserted.
SYS_PRS# : will active(low) when over voltage is detected and reset the system.
