8. Troubleshooting
This section addresses common issues you might encounter with your XTi6002 amplifier.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cord disconnected; power outlet faulty; amplifier fuse blown. | Check power cord connection and outlet. Replace fuse if necessary (refer to service manual or qualified technician). |
| No sound output | Input cables disconnected; speaker cables disconnected or faulty; incorrect input selection; amplifier in standby mode. | Verify all cable connections. Check input source and amplifier settings. Ensure amplifier is powered on and not in standby. |
| Thermal LED illuminated / Amplifier shuts down | Overheating due to blocked ventilation or excessive load. | Ensure adequate ventilation. Reduce output level or speaker load. Allow amplifier to cool down. Check fan operation. |
| Distorted sound | Input signal too high (clipping); speaker impedance mismatch; faulty speaker. | Reduce input signal level. Verify speaker impedance matches amplifier's capabilities. Test with a different speaker. |
| Fan noise / Fan not operating correctly | Dust accumulation; faulty fan bearing. | Clean ventilation grilles. If noise persists or fan fails, contact qualified service personnel. |
