Firmware Update (Version 1004 or Higher)
Manufacturer service bulletins indicate that synchronization dropouts are primarily caused by inefficient frequency-hopping algorithms and power-state logic errors. This software patch recalibrates the 5.8GHz wireless link to prioritize low-latency stability and prevents the satellites from entering premature sleep cycles during active playback.

Main PCBA (Transmitter Module)
If firmware does not stabilize the connection, the hardware root cause is typically a thermal or voltage-induced degradation of the 5.8GHz transceiver module located on the Main PCB. Replacing the board restores the signal strength and signal-to-noise ratio required for high-bandwidth uncompressed audio transmission.

Rear Speaker Receiver PCBA
In cases where only one specific rear speaker is dropping out (often indicated by a blinking blue LED), the internal receiver PCB has likely suffered a component failure on its wireless antenna trace or power regulation circuit, preventing it from maintaining a stable handshake with the main bar.
