To determine if your TV backlight is broken, observe for dim screens, uneven brightness, or flickering images even after adjusting brightness settings. If parts of the screen are darker than others or if the screen is completely dark but the TV still has sound, this indicates a backlight issue. Using a flashlight, shine it on the screen at a close distance; if you can see a picture, it's likely the backlight not functioning properly.
