1. Damage to the hardware: Physical damage, like drops or bumps, can cause the backlit circuit or other parts to break or become disconnected.
2. Display Connector Problems: If the display connector is loose or broken, it can break the link between the screen and the motherboard. This can cause the backlight to stop working.
3. Faulty Backlight IC: The strength of the backlight is controlled by the backlight IC, which is an integrated circuit. If this part breaks, it could cause problems with the lighting.
4. Software Problems: Sometimes, a software problem or update can cause problems with how the lighting works.
