What Causes the Backlight to Fail on a Tv

TVs use a light source behind the screen to show images. This light source is called the backlight. Backlight failure can occur from drop damage, water damage, or it can simply be the result of a defective part. The backlight filter is a thin wire that sits between the backlight and the LCD screen. When a short in the backlight circuit occurs, the thin wire inside the filter breaks, severing power from the backlight LEDs. This can cause the backlight to fail.
