Reasons for the Mercedes-Benz E300 central control screen not lighting up?
2 Answers
Mercedes-Benz E300 central control screen not lighting up is caused by defects in the central control system, power circuit failures, and the central control system not being updated and upgraded in time. Mercedes-Benz: Mercedes-Benz is a German automotive brand renowned for luxury and high performance, headquartered in Stuttgart, Germany. It is a member of the Daimler AG, with a product line that includes various passenger cars and medium to large commercial vehicles. Mercedes-Benz E300: Taking the Mercedes-Benz E300 as an example, it is a medium-large 4-door 5-seater sedan, with a length, width, and height of 5078mm, 1860mm, and 1480mm respectively, a top speed of 240 kilometers per hour, and equipped with a 9-speed automatic transmission.
Having run a Mercedes repair shop for over a decade, when I see an E300's center console screen not lighting up, my first suspicion is always the fuse. Mercedes fuse boxes are usually easy to locate in the trunk or on the driver's side—check if the INFOTAINMENT-related fuse is blown. If the screen still doesn't light up after replacing the fuse, it might be due to loose wiring connections or a short circuit, often caused by rough road conditions shaking wires loose. Avoid tampering yourself to prevent electric shock risks. Sometimes, the screen hardware ages or gets damaged by water ingress, requiring professional inspection. Software glitches are also common—try rebooting the system by holding the volume-down and power buttons together for 10 seconds to force a restart. Insufficient voltage from battery or alternator issues can cause the entire system to go dark. Delaying repairs can affect AC controls or navigation, so I recommend visiting a dealership soon for diagnostic tool checks. Keeping electronic components dry during car washes helps reduce failure rates.
