LG G7 ThinQ Speaker System Replacement

简介

If your LG G7 ThinQ (model IMEI 358159091436289) is producing distorted, intermittent, or no sound from the external speakers, use this guide to replace the speaker system.

The speaker system produces all the sound/audio that exits the phone. A faulty speaker will produce distorted or no audio.

Before using this guide, inspect the speakers for debris that may be interfering with sound quality. Typically, a small buildup of dust can be removed using an ESD-safe brush or small dust blower.

Before beginning, make sure the phone is powered off and is disconnected from any source of power.
