No Power: Check the power cord connection, the AC outlet, and the power switch on the amplifier.
No Sound: Verify the input source is on and correctly connected. Check the volume level and input selector. Ensure the speakers are correctly connected and not faulty.
Distorted Sound: Check for any overload indicators. Reduce the volume level. Ensure that the impedance of the speakers matches the amplifier's specifications. Inspect the speaker connections for any loose wiring.
Overheating: Ensure adequate ventilation around the amplifier. Do not operate the amplifier in enclosed spaces or near heat sources.

VI. Maintenance and Cleaning: Regularly inspect the amplifier for dust accumulation and clean it with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners. Do not attempt to repair the amplifier yourself; contact a qualified technician for any repairs needed.

VII. Warranty Information: The warranty period and terms are specified separately, and usually provided with the purchase documentation. Retain your purchase receipt and warranty information for future reference. The warranty typically does not cover damage caused by misuse, neglect, or unauthorized repairs. Refer to your specific warranty documentation for complete details.
