    Hi Yusuke

     Normally this fault is quite hard to be triggered. Some possible reason, like incorrect audio input, or the CH has some damage.

     Maybe you could firstly check if DC load diag could pass for CH3. Then if CH3 still could goes into idle state, check the OUTP and OUTM waveform.
