Because backlight failure is a frequent problem, it’s the first item to check. The simplest method to do so is to turn on your screen, place a flashlight next to it, and verify whether you can see the picture through it. The picture would be incredibly black, as if the screen’s brightness had been turned far down.
Similarly, What causes LED backlight failure?
Damage to the circuit board’s electrical traces may also cause backlight circuit failure. The backlight circuit will not carry power to the backlight LEDs if the electrical traces buried in the board are accidently severed—for example, by attempting to secure the board with a too big a screw.

Secondly, How do you tell if your TV bulb is burnt out?
Symptoms and Signs If your bulb suddenly goes out, you may hear a popping sound before the screen goes black. You’ll be able to hear your television, but you won’t be able to see it.

People also ask, How do I know if my LED is blown?
It’s a light-emitting diode (LED). Connecting it to a battery and seeing whether it lights up is the simplest approach to detect if it is damaged. Because you can’t unscrew the white plastic device, the connecting wires, resistor, or LED itself might be harmed if the LED doesn’t glow.
