Main Logic Board
The red blinking light is a diagnostic code for a system-level interrupt, typically caused by a failure in the digital signal processor (DSP) or the network interface controller. This occurs when the bootloader cannot verify the firmware's digital signature or when the Wi-Fi module fails its Power-On Self-Test (POST). Replacing the main PCB restores the core processing logic and clears corrupted flash memory states that prevent the system from booting.
