Title
Logitech S-LG3 Subwoofer Logitech Soundman Speaker Capacitance Replacement
Introduction
The purpose of this repair is to fix crackling or sizzling subwoofer that may give unpleasant sounds. Most of the times the sizzling sound appears gradually along with the use of these speakers. It is mostly caused by a over-stressed capacitor : generally the circuitry of the cut-off is badly designed and the capacitor is shortened. Sometimes the damage to the capacitor can be observed as the top of the capacitor has a curved shape. Sometimes it is not visible. I replaced that capacitor with a higher-grade component : here a capacitor dedicated to the automotive industry.
