The system's internal architecture is divided into three primary sections:
Schematic fix: Replace Q101 (typically a 2N3904 or BC547). logitech z-5500 schematic diagram
The capacitors in the power supply section (primary and secondary) are notorious for drying out (capacitor plague). A schematic shows the capacitance and voltage ratings required for recapping. The system's internal architecture is divided into three
: 62 Watts RMS per channel (or roughly 69W peak according to some community testing). Frequency Response : 33 Hz – 20 kHz. 2. Core Input/Output Interfaces as it contains dangerous high-voltage sections.
This is the large PCB located inside the subwoofer cabinet. This is where the official schematic would be most valuable, as it contains dangerous high-voltage sections.
