Main Logic Board (A-Board)
The Main Logic Board contains the SoC and system firmware. If the network controller or the internal communication bus (I2C/USB) fails due to a hardware defect or corrupted bootloader state, the processor cannot complete the wake-up sequence from standby, resulting in an unresponsive unit.

WiFi/Bluetooth Module
This granular module is a frequent point of failure in Bravia models. A thermal or electrical failure in this module can pull down the shared communication rail, effectively 'braking' the system boot sequence and causing the TV to remain in a perpetual off-state.

Power Supply Board (G-Board)
The Power Supply Board must provide a stable Standby voltage (STBY) to the Main Board to listen for the power-on command. A failure in the secondary rectification stage or a blown fuse in the AC-to-DC conversion path will prevent the TV from receiving any power regardless of the firmware state.
