Main PBA Assembly for LG G3 LS990

The Main PBA Assembly for your LG G3 Ls990 is the complete main printed board assembly — the central circuit board carrying the processor, memory, power management, RF components, and all core device functions. It is required when the board has sustained liquid damage, multiple IC failures, or physical damage beyond individual component repair on your LG G3 Ls990.

Yes — this complete board replacement carries all integrated components to the same specification as the original main PBA on your LG G3 Ls990. Full device functionality across all features will be restored after professional installation and correct transfer of IMEI and device-specific data where applicable.

A full PBA replacement is the correct solution when board-level diagnosis has confirmed multiple simultaneous IC failures, extensive liquid corrosion, or physical board damage that makes individual component repair uneconomical. Always perform systematic board-level diagnosis before committing to a full PBA swap on your LG G3 Ls990.

It is an advanced repair requiring complete device disassembly, careful transfer of all flex cables, connectors, and ancillary components to the new board, and correct reassembly. IMEI and software considerations must also be addressed. Professional installation is strongly recommended for your LG G3 Ls990.

Yes — a 7-day replacement warranty covering manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Board assemblies with physical damage or that have been installed are not eligible for return. For more information, check out SAHII's Return Policy.
