Main PCBA (Printed Circuit Board Assembly)
The Main PCBA houses the Bluetooth SoC and the RF front-end responsible for signal processing. Intermittent dropouts are typically caused by a failure in the crystal oscillator or a thermal defect in the logic board's power management IC, which causes the radio to briefly lose synchronization with the source device's clock. Replacing the PCBA ensures a fresh Bluetooth transceiver and updated hardware-level instruction sets.

Internal Lithium-Ion Battery
If the battery's internal resistance increases, it can cause transient voltage sags during high-current operations, such as high-bitrate audio processing or long-range transmission. These sags can trigger the Bluetooth module's brownout protection, resulting in a momentary audio cut-out as the radio attempts to re-establish its power state.
