LED Driver Board (LD Board)
The LD board is responsible for local dimming and regulating current to the LED arrays. A 6-blink code specifically indicates the protection circuit has detected a failure in this regulation loop. Replacing this board is the most common board-level solution for this specific model's backlight error.

Internal LED Backlight Strips (Full Set)
If one or more LEDs in the full-array local dimming (FALD) grid fail or short, the driver board will sense the impedance shift and trigger the 6-blink protection mode. This is a common physical failure in high-brightness HDR sets like the X900F.

Power Supply Board (G-Board)
The Power Supply board provides the VLED (Backlight Voltage) to the LD board. If the power supply's backlight rail collapses under load, the system will report a 6-blink error even if the LEDs and driver are functional.
