6.3 Doesn’t start when charger is inserted.
Open the phone and check for liquid damage.
Check the pads at the system connector for oxidation and burn damages, especially
on pad 10 (GND, fig. 6.4).
Fig. 6.4
Measure the resistance from DCIO to VBATT (~390 ohms, fig. 6.5).
Fig. 6.5
• If the resistance is too low, replace V453 (class B).
• If it is too high, measure the resistance in R468 (class B, ~0.1 ohms) and R467
(Class A, ~390 ohms, all displayed in fig. 6.6).
* If the measured values are correct, check the resistance from DCIO to R467
(~0 ohms, fig. 6.5, 6.6).
