Filter For LG GC900 Viewty Smart

The Filter on your LG Gc900 Viewty Smart is a passive component — typically a SAW (Surface Acoustic Wave), BAW, or LC filter — that removes unwanted frequency content from a specific signal path. RF filters on the motherboard remove out-of-band interference from mobile network signals, while audio filters remove noise and harmonics from audio signal paths. A faulty filter allows unwanted signals through — causing RF interference, reduced signal quality, or audio noise on your LG Gc900 Viewty Smart.

Symptoms include persistent audio noise or hiss that is not caused by a software setting, RF signal quality degrading below what antenna and IC replacements can resolve, interference patterns in received audio during calls, and specific frequency band performance being below specification on your LG Gc900 Viewty Smart — all after confirming active components are functional.

A Filter is a passive component — it contains no active circuitry and requires no power supply. A Filter IC is an active chip that uses powered circuitry to perform filtering. Passive filters are simpler, smaller, and cheaper to replace but require precise specification matching. Active Filter ICs offer more sophisticated filtering with configurable characteristics on your LG Gc900 Viewty Smart.

No. Filters are micro-SMD passive components soldered onto the LG Gc900 Viewty Smart motherboard. Replacement requires SMD soldering skills, a precision iron or hot air station, flux, and magnification. This is a component-level repair for experienced board technicians only.

Yes — a 7-day replacement warranty against manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Once soldered, the component is considered used and cannot be returned. For more information, check out SAHII's Return Policy.
