Hi all,
THis is a liquid dmg board only near Q7030 ,Q7035, C7036,C7035,C7037. I replaced all these and still get 3.77v on R7021 & R7022 current sensing resistors.
Resistance between R7021 & 21 is 21ohms and R7051/R7052 is 2.9ohms.
I replaced U 7000 still the same.
q7080 all pins have 16.5v. Q7085 pin 1-4 I get 16.5v then the rest 3.7v
R7086 CHGR_AGATE both side 16.5v.
Well when the battery connected, I get 16V R7021/ R7022 and 10v on PPBUS_G3H and fan goes high.
this is what I get with our battery connected on U7000.
PIN 1 = 14.5V PIN 8 = 3.3V
PIN 2 = 13.9V PIN 9 = 3.7V
PIN 3 = 3.9V PIN 10 TO 18 = 3.3V
PIN 4 =3.3V PIN 19 = 8.9V
PIN 5 = 3.3V PIN 20 =7.8V
PIN 6= 3.3V PIN 21 =0V PIN 22 0V
PIN 7 = 3.3V PIN 23/24 = 3.3V , PIN 25 8.4V PIN 26 =15.V , PIN 27/28 3.7V
Appriciate your help.
Thank you
