LED Backlight Strip Set
The TU7000 series frequently experiences failures in the LED array where a single failed diode or a loose interconnect joint breaks the series circuit. This results in the screen appearing black even though the TV is powered on and producing audio. Replacing the complete set of strips restores the necessary illumination for the LCD panel.

Power Supply / LED Driver Board
If the LED strips are functional, the failure often lies in the LED driver circuit located on the power board. This component is responsible for stepping up voltage to power the backlight array; if this circuit fails, the LEDs will not illuminate despite receiving a 'power on' command from the main board.
