Default JVC Subwoofer distorted

Hi Everyone,

I am trying to fix a JVC XV-THA35 amplifier. It has a DSP circuit and has 2 front speakers, 2 rear speakers, 1 center speaker and 1 subwoofer outputs. Out of the 6 outputs, only the subwoofer output is soft and distorted, the others are fine. It uses 4pcs IRF530N mosfets on the power supply board and I found that one of them including a diode has shorted. Can this be the cause of the subwoofer distortion. Anyone, please advise.

Thank you
