Charging Connector Flex / PCB Board for LG V40 ThinQ

The Charging Connector Flex / PCB Board for your LG V40 Thinq is a small printed circuit board on a flex cable that houses the USB charging port and typically the primary microphone, signal antenna connection point, and sometimes a secondary speaker or headphone jack — all assembled as a ready-to-install unit. It is the physical point where your charger plugs into your LG V40 Thinq and manages all associated bottom connector functions.

Signs include the charging cable not fitting firmly in the port, charging only at certain angles, no response when a cable is plugged in despite a working charger and cable, USB not being detected by a computer, microphone failure during calls, and audible crackling or static when the cable is moved during charging on your LG V40 Thinq.

Yes — in most cases. If fast charging stopped due to a damaged port or a fault on the flex board, replacing the Charging Connector Flex / PCB Board restores original fast charging speeds on your LG V40 Thinq. If the Charging IC on the motherboard is also damaged, that will need to be addressed separately.

No — in most cases this board connects to the motherboard via a snap-fit or ZIF connector. The port is part of the board assembly rather than a separate soldered component — making this a more accessible repair than port-only soldering. Opening the phone and basic repair tools are required on your LG V40 Thinq.

Yes — a 7-day replacement warranty covering manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Parts showing physical damage from improper installation are not covered under warranty. For more information, check out SAHII's Return Policy.
