Logitech Z-5500 Schematic Diagram: A Comprehensive Guide
- Visual Inspection: Burnt resistors or bulging capacitors are visible without a diagram.
- Signal Tracing: Using an audio probe or oscilloscope, a technician traces the signal from the DIN input jack on the amp board, through the coupling capacitors, and to the amplifier chip pins. If signal enters the chip but doesn't leave, the chip is dead.
- Short Detection: If the fuse blows immediately, the technician checks the MOSFETs in the power supply and the output transistors on the amp chips for short circuits (continuity between source and drain).

The heart of the system is a heavy toroidal transformer that outputs several AC voltages, most notably a dual-rail supply for the power amps and a lower voltage for the logic circuits.
