Internal Power Supply Board
The internal AC-to-DC switch-mode power supply board is the most common failure point for total power loss. Thermal stress within the compact, unvented soundbar enclosure leads to the premature drying of electrolytic capacitors or the failure of the pulse-width modulation (PWM) controller. Replacing the power board restores the necessary DC voltage rails required for the logic and amplifier stages to function.

Main Logic PCB
If the power supply is delivering the correct voltage but the unit remains unresponsive, the main logic board has likely suffered a processor failure or firmware corruption. This board manages the 'soft' power-on signal and the Infrared (IR) receiver interface. Replacing this assembly addresses failures in the command-processing circuit.
