⟩ A question I am often asked is "How can I tell if the backlight or inverter has failed on my laptop/monitor as I can only just make out an image?
The answer is that there are several causes of a dim display or the failure of a backlight to illuminate the screen. As most people are aware, inverter and backlight failure are the most common. Other causes are:- a faulty or damaged LCD/Inverter cable, Faulty motherboard and a faulty screen.
