1. Audio source issue: Check if the audio source is working properly and if the connection is correct. You can try using another device (such as a mobile phone, MP3 player, etc.) as the audio source for testing.

2. Connection issues: During the power amplifier wiring process, it is easy to encounter poor contact or misconnected wires, resulting in the inability to transmit audio normally. Check all connecting cables for looseness or damage. Especially the audio input and output connection lines.

3. Input indicator light: Usually, the amplifier will have an input indicator light. Confirm whether the selected input channel is correct and ensure that the corresponding input indicator light is on.

4. Volume control: Check if the volume control of the amplifier is adjusted to a low or silent state. Also check the volume settings of the audio source device.

5. Speaker and output port: Check if the speaker itself is damaged, and verify if the output port of the amplifier is securely connected.

6. Mute function: Ensure that the amplifier is not set to mute or silent mode.

7. Internal faults: If no problems are found during the above inspections, it may be due to internal faults in the power amplifier. Internal faults in the power amplifier may involve multiple aspects, such as power amplifier chip faults, capacitor aging, control circuit faults, etc. This requires professional maintenance personnel to carry out repairs.

Checking these possible issues one by one should help you identify the reason for the lack of sound. If the problem still cannot be solved, it is recommended to contact professional maintenance personnel for inspection.
