LED Backlight Strip Set
The Q60A is an edge-lit model where the LED diodes are under high thermal stress. If a single diode fails or the strip overheats, the power supply's protection circuit cuts power to the entire backlight array. This results in a black screen while the audio remains functional because the main logic board is still powered and receiving signals.

Power Supply Board (PSU)
The Power Supply Board contains the LED driver circuit. If the capacitors or boost converter responsible for the backlight voltage fail, the LEDs will not illuminate despite being functional. This is confirmed if the 'flashlight test' reveals a faint image on the LCD panel.

Main Board
The Main Board handles video processing and signal output to the panel. A localized failure in the video SoC (System on Chip) or the LVDS connector can prevent image data from reaching the panel while allowing the independent audio processing path to continue operating through the speakers.
