[SOLVED]820-2327 no green light on charger

[jgraffis]

i've got this 820-2327, i know its an old one. it doesnt show a green light on the charger after water damage. i started taking messurements around the isl6258 chip and found a strange reading on chgr_agate- 16v on pin one of r7001 .04v on pin 2. check resistance of r7001 to find it has 62kohms, checked the resistor r7098 to find 280ohms instead of 100kohm, removed r7098 checked resistance at the pads and still had 280ohms resistance.

for some reason im not getting chgr acok out of the isl6285 but not sure about the 280ohs resistance on r7098.

any ideas?

q7000 is dead, but should not affect the green light. Replace Q7000 but ISL is probably dead too

i changed the q7000 that fixed the issue now i got short to ground on chgr_acok, removed isl6258 found short on char_acok pad , checked smh_bc_acok found short is in the smc. This thing is too old to replace the smc so its going in the donor pile.
