No charging
Pre-Check:
Connect a working phone to the charger (e.g. ACP-7, ACP-8 or ACP-12), and check if the battery indicator of the phone
display is scrolling. If it works, connect the faulty phone to the same charger, and check the battery indicator in the
display.
- If the phone does not charge, follow the repair instructions:
o See “No charging”
No charging
If the charging does not work, probably the flex foil to X100 flex connector is broken, the connector itself is faulty or
one of the components one the PWB does not work.
- First try to change the grip module and test with a working one.
Note! For disassembling instructions refer to service manual NHM-4 8910, chapter “Disassembly and Troubleshooting
Instructions”
- If the problem is solved, probably the flex foil was broken or had no connection to the connector. (See also pictures
under chapter “Microphone sometimes does not work”)
- If the fault “no charging” persists, check lines from X100, Pin 1-4 (for measure points see picture X100 flex
connector under menu “No Vibra”) to UEM for broken soldering or disconnections, and resolder or change faulty
components.
