Signs your TV backlight might be broken include a screen that's completely dark with no picture despite the TV being on, a flickering display, or dim areas across the screen that are unevenly lit. If sound is coming from your TV but there's no image, or if adjusting the brightness setting doesn't change the darkness of the screen, these could be indicators of backlight failure. For verification, shine a flashlight onto the screen; if you can see a picture faintly, the backlight is likely the issue.
