Fix #2: Perform the Flashlight Test
If your smart TV appears dark but has no sound problems, its backlighting system might be faulty. To be sure, you can do the flashlight test; in this test, you’ll need to have a working flashlight to shine onto the screen.
To do the flashlight test, do the following:
- Turn on your Vizio smart TV.
- Next, place yourself two inches away from the TV screen and point your flashlight directly onto the screen.
- If you see an unclear image on the LED screen, your smart TV’s backlight inverter board might have problems.
The backlight inverter board is a component that powers up the LCD backlighting system of your screen which is responsible for illuminating your LCD screen, especially in low-light conditions. To replace this, you’ll need to consult Vizio Support.
