Is the Central Control Screen Not Lighting Up Due to a Fuse Failure?

Is the central control screen not lighting up due to a fuse failure? The reason is that the fuse burns out due to excessive load. The fuse is located under the interior trim panel on the side of the main driver's dashboard. Its working principle is based on electromagnetic induction, where the conductor cuts the magnetic field lines to generate an electric potential, converting the mechanical energy of the prime mover into electrical energy output. The fuse consists of a fuse element, electrode parts, and a bracket. Fuses can be classified into flat tubular fuses, pointed tubular fuses, guillotine fuses, spiral fuses, blade fuses, flat fuses, wrapped fuses, and SMD fuses. Their function is to quickly blow when the circuit current exceeds twice the rated current of the fuse, thereby protecting the circuit.
I've been driving for over twenty years, and a non-illuminating center console screen is really not uncommon—fuse failure is definitely one of the common causes, but not the only possibility. From my experience, sudden blackouts in the center console screen are mostly related to electrical circuits. A blown fuse is as likely to happen as a broken safety switch; it could also be due to a short circuit, aging wires with poor contact, or hardware damage to the screen itself. Last time I encountered this issue, I first checked the fuse box, located just below the dashboard, found the corresponding fuse, confirmed it was blown, and replaced it with a new one. If the screen comes back on after replacing the fuse, the problem is solved; if not, other factors need to be considered, such as internal component failure in the screen or a software crash in the infotainment system—sometimes restarting the vehicle can temporarily fix it. Modern car center consoles have many functions affecting navigation and music, so safety first—it's best to get it repaired promptly and not delay.
