DC Power Input Charging Board
Mechanical stress from frequent insertion and removal of the power adapter leads to solder joint fatigue or physical deformation of the internal contact pins. Since the battery was already replaced, the lack of current flow is likely due to a continuity break at this input interface, preventing the charging circuit from receiving external power.

Main Logic Board
If the input jack is intact, the failure often resides in the Power Management Integrated Circuit (PMIC) or the SMD (Surface Mount Device) inductors. These components regulate the step-down voltage required for Li-ion charging; if they fail due to thermal overstress or a voltage spike, the board will power the unit but fail to initiate a charge cycle to the battery.

AC Power Adapter (20V 4A)
The charging logic of the Boombox 2 requires a specific voltage and current threshold to trigger the battery management system (BMS). If the external power brick has suffered capacitor degradation or cable internal fraying, it may provide enough 'float' voltage to show a light but insufficient amperage to overcome the internal resistance of the charging circuit.
