LED Backlight Strip Kit
The most frequent cause of 'sound but no image' is the failure of one or more LEDs within the backlight array. TCL 6-series models utilize a series circuit; if a single LED fails, the entire circuit may open, or the LED driver may trigger a protection mode, shutting down all illumination while leaving the Main Board and Audio circuits powered.

Power Supply Board (LED Driver)
The Power Supply Board contains the LED driver circuitry responsible for boosting voltage to power the backlight strips. If the capacitors or MOSFETs in this specific circuit fail, the TV will maintain audio and logic functions but will be unable to provide the necessary voltage to strike the backlights.

T-CON Board
The Timing Control board processes the image data for the LCD panel. While a failed T-CON usually results in vertical lines or a grey screen, a total processor failure on this board can result in no data being sent to the pixels, appearing as a black screen even if the backlights are technically operational.
