Member: 1675922 Status: Offline Thanks Meter: 61 | 3.7v on PPVBUS_USB_DCIN Without battery, when connected to usb not seen by PC. Voltage on PPVBUS_USB_DCIN is 3.7V and same voltage on PPVBUS_PROT. I replaced Q8123, DZ8120 and C8145 and still the same. When Q8123 is removed, the PPVBUS_USB_DCIN jump to normal 4.7V. No PPVCC_MAIN present. Check other boards, and normal voltage is about 4.7V on PPVBUS_USB_DCIN When connect to battery and plug USB is detected as DFU mode and then as Recovery mode...all seems normal. What can it be? Thx, |
