Won't charge when is turned on

I have a costumer iPad and it won’t charge, i have changed the charging port but still the same problem, after i removed the shield and started to measure the components with multimeter I noticed some condensators are shorted to groud, but i can't identify the net because i don't have schemes for it. The shortened condensators are near the PMIC between the coils, none of them are cracked or damaged and the iPad don't heat. If someone has an idea what to do i would appreciate. Thanks in advance.
