Safety Precautions

Before servicing, disconnect AC power and remove all connected devices.

Electrostatic Discharge (ESD): Use grounded wrist strap when handling PCBs.
High Voltage: Power supply contains hazardous voltages even when unplugged; discharge capacitors.
Mechanical Safety: Use proper tools; avoid damaging internal connectors and cables.
Reassembly: Ensure all screws are tightened to specified torque; verify cable routing.

WARNING! Only qualified technicians should perform service. Incorrect reassembly can cause fire, electric shock, or damage.

Disassembly Procedure

Power off and unplug unit. Remove docked device.

Remove rear panel: Unscrew 8 Phillips screws along perimeter.
Detach grille: Carefully unclip plastic grille from front baffle.
Access main assembly: Remove 4 screws securing waveguide/enclosure assembly.
Disconnect cables: Note positions of power, speaker, and dock connector cables.
Remove PCB: Unscrew PCB mounting screws; lift board from standoffs.
Extract power supply: Disconnect AC input wires; remove mounting screws.

CAUTION! Label all cables and connectors. Avoid stressing flexible cables.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No power (LED off)	AC input, fuse, power supply	Check wall outlet; test fuse F1; measure output at TP1/TP2.
No sound from dock	Dock connector, audio IC	Clean dock contacts; test audio path from dock to amplifier.
Distorted audio	Amplifier, speakers	Test with known-good source; inspect speaker cones for damage.
Remote not working	Batteries, IR receiver	Replace remote batteries; check IR1 voltage and signal.
No charging	Dock power lines, charging IC	Verify 5V at dock power pin; check charging circuit on PCB.

Reset: Unplug AC for 60 seconds; replug. For persistent issues, replace main PCB.
