So this system is not turning on, no light on charger when plugged in.
I start troubleshooting and i get 0v everywhere.
Replaced r6905, c6990 and c6999 now i have 3.6v and 17.2v on both sides of r6905.
D6905 has 3.6v on pin 1 but 2.7v on pin 5.
Q7050 has 1v everywhere less pin 4 which has 0.22v.
Pin 4 is CHGR_BGATE which comes from U7000.
U7000 has:
0v on DCIN,
4v on ACIN,
0v on VDD,
1.7v on PP3V42 G3H.
U7000 CHGR_DCIN comes from D7010 wich has 0v on DCIN side but 17.22v on the other side.
I upload schematics see if someone can give a clue.
Thanks in advance.
