Main Logic Board (PCBA)
The main logic board houses the SoC and the flash memory where the system firmware resides. Persistent flashing white light indicates the system is unable to successfully load the OS or initialize the network stack, usually due to localized hardware degradation of the memory module. Replacing the PCBA is the only surgical method to resolve a failure in the boot sequence when software-level resets fail.
