回答“TCL No Backlight, Black Screen, Flashlight Test Good, Menu Sounds Good”I am repair tech. From the troubleshooting you have strong chance you have LEDs bad. This model is easier than most to change LEDs. There is 2 version of LED strips. You will need to use numbers on the strips and/or LCD panel number to get correct parts. Do not order by model number alone. Good luck
