Power Supply Board (SMPS)
The Switch Mode Power Supply (SMPS) is responsible for converting AC to the DC rails required for the logic board and backlights. A blinking red light signifies that the board has detected an internal component failure or an improper load, causing it to cycle power in a protection loop to prevent further circuit damage.

Main Logic Board
The Main Board acts as the brain of the unit, sending the 'Power_On' command to the PSU; if the system-on-chip or memory fails to initialize, the handshake is lost. This interruption causes the standby LED to blink an error code indicating the boot sequence cannot be completed.

LED Backlight Strip Set
In many Crystal UHD models, a single shorted LED within the panel's backlight array creates a resistance imbalance. The Power Supply Board detects this current fluctuation and immediately enters a shutdown state to prevent thermal runaway, resulting in the blinking standby light symptom.
