Main Board
The Main Board manages the boot sequence and handshake with the Power Supply. A failure in the SoC (System on Chip) or the onboard firmware prevents the TV from completing its initialization, causing the Watchdog Timer to trigger a reset and restart the loop.

CONF
Power Supply Unit (PSU)
The PSU must provide stable DC voltage to the Main Board and the LED backlights. If the filtering capacitors or the switching MOSFETs fail to maintain voltage under the initial load of the screen turning on, a brown-out condition occurs, forcing a system reboot.

LED Backlight Strip Set
If an LED in the backlight array fails or shorts, the LED driver circuit detects an over-current or under-current condition. For safety, the driver communicates a fault to the processor, which immediately terminates power and attempts a restart.
