If it is a power problem, you can check whether the fuse is blown and whether the power cord is damaged, and repair or replace it. If it is an audio connection problem, you can check whether the connecting cable is loose or damaged, and re-insert or replace the connecting cable. If there is a sound quality problem, it may be necessary to adjust the equalizer setting of the power amplifier or replace the damaged speaker. For more complicated problems, it may be necessary to find professional maintenance personnel for maintenance or repair.
