Zhongwei,

I don't know what is going on, but can you let me know more details, so i can give some suggestion.
1. No output signal means No PWM switching or No audio signal?
2. how is the FAULT and warning LED status when this happen?
3. from GUI, can you read out any fault?

Please check these first, then we can go ahead check with more points.
