| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| No Power (LED off) | AC adapter, fuse, power board | Check wall outlet. Test AC adapter output (12V DC). Check fuse F1 on power board. |
| Power LED on, No Sound | Input selection, mute, amplifier | Ensure correct input selected. Check mute status. Probe amplifier output to speakers. |
| Sound from one side only | Speaker, cable, amplifier channel | Swap speaker connections to isolate. Check for broken wire. Test amplifier channel output. |
| iPod not charging/recognized | Dock connector, dock board | Inspect dock connector for damage. Check dock board for 5V charging voltage. Test dock board data lines. |
| Remote not working | Battery, IR sensor, microcontroller | Replace CR2032 battery. Clean IR window. Check IR sensor output on main PCB. |
| Distorted Audio | Speaker damage, amplifier fault | Inspect speaker cones for tears. Test with known-good audio source. Check power supply ripple. |
The system microcontroller contains non-user-upgradable firmware. Diagnostic mode can be accessed for testing.
Note: Firmware corruption is rare. If suspected, main PCB may require replacement.
Reverse of disassembly. Ensure all connections are secure.
