820-2936 led green not always

[raainxx]

Hi,
it's difficult to have the green led on this board (is very low light green) sometimes work.
the board work with an full charge battery, the battery indicator working, no liquid, i try new magsafe board 820-2565, same issue.
when i have not green led:
PPBUS 12,14V
SMC_PM_G2_EN = 3,491V
Pp3v42_g3h=3,49v
SMC_AOK=3,31V
I use an original charger

Voltage on ADPATER_SENSE and SYS_ONEWIRE?

 

[raainxx]

ADPATER_SENSE=0V
SYS_ONEWIRE=0V
SMC_AOK=0V often

Voltage on C7005? Check resistance between pins 17/18, 27/28 of the ISL6259

C7005 move between 2,4V and 2,6V
17/18 = 3ohm
27/28 = 20ohm
I found the problem, i change R7005 10kohm instead of 20ohm, now the green led work.
thanks for your help
