Front Panel UI PCB Assembly
The UI PCB houses the rotary encoders and the surface-mounted LED rings. A failure of the backlight while the device processes audio indicates a localized power or data failure on this board, often due to a failed shift register or LED driver IC that manages the illumination matrix.

Internal UI Ribbon Cable
This multi-conductor cable carries the 5V/3.3V logic and PWM signals required to drive the LED rings. If the cable becomes partially unseated or develops a micro-fracture in the copper traces due to thermal cycling or mechanical stress, the backlight circuit will open while other functions remain intact.

Mainboard Assembly
The mainboard contains the primary microcontroller that sends serial data to the UI board. If the specific GPIO pins or the serial clock line responsible for the UI feedback loop fail, the LEDs will receive no instructions to illuminate.
