Main Logic Board (A-Board)
The Main Board handles the system-on-chip (SoC) logic and interprets hardware sensor feedback. In the A80K series, a logic failure or corrupted eMMC on this board frequently triggers a protection loop, resulting in a blinking red light and a failure to initialize the boot sequence.

Power Supply Board (G-Board)
The Power Supply board provides the necessary DC voltages to both the Main Board and the OLED panel. A failure in the standby rail or the PFC (Power Factor Correction) circuit will prevent the TV from transitioning from a 'Ready' state to an 'On' state, causing the diagnostic LED to flash.

T-CON Board
Specifically associated with the 5-blink red light error code on Sony OLEDs, the T-CON (Timing Controller) manages signal delivery to the OLED cells. If the T-CON fails to respond to the Main Board during the 'handshake' at startup, the system shuts down for panel protection.
