My beloved pm7003 amp is not working.. Right channel speaker out put is not working and also same at headphone output. All other function is working fine.
@daniely you’ll have to start taking it apart and check a couple of voltages on the speaker terminal board (the board that has the output mounted to it). Check the voltages on your relays L751 L752 and L753 compared to the diagram. Let us know what you get.
