The solutions for a Mercedes-Benz screen not lighting up are: 1. Restart the car; 2. Seek timely repairs. Models under Mercedes-Benz include: Mercedes-Benz GLS, Mercedes-Benz GLE, Mercedes-Benz GLC, Mercedes-Benz GLA, Mercedes-Benz CLA, etc. Taking the 2021 Mercedes-Benz GLS as an example, it is a mid-to-large-sized car with body dimensions of: length 4988mm, width 1890mm, height 1424mm, and a wheelbase of 2939mm. The 2021 Mercedes-Benz GLS is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 184PS, a maximum torque of 280Nm, and a maximum power of 135kW, paired with a 9-speed automatic transmission.

As a seasoned veteran who has spent many years in the dealership, when encountering a black screen issue with a Mercedes, my first recommendation to owners is to try the most basic step: reboot the system, just like restarting a phone. After starting the car, press and hold the screen's power button for about 15 seconds to force a restart; this method has resolved many software freeze issues. If the screen still doesn't light up, check the fuse box; Mercedes fuse locations are typically under the driver's seat or near the engine bay—refer to the manual's diagram to replace the fuse. Another common cause is insufficient battery power; test the voltage—if it's below 12 volts, recharge or replace the battery, as unstable voltage can lead to failures in the entire electronic system. If none of these work, the screen itself may have hardware damage or loose wiring; I've seen cases where internal connectors oxidized or loosened due to bumps, requiring professional diagnosis. Don’t overlook regular maintenance, such as software updates, which can prevent similar malfunctions.

I'm passionate about studying automotive electronic components, and I've analyzed that the reasons for a Mercedes-Benz screen not lighting up are often intertwined with multiple factors. The most common issue is a system software malfunction; using an OBD diagnostic tool to connect to the interface and scan for error codes can help identify if it's a bug, and updating the firmware might resolve it. On the hardware side, check if the connectors behind the display screen are loose or corroded; Mercedes-Benz plugs are prone to dislodging due to vibration. The power supply module is also crucial, as a damaged relay or an aging battery can cause power interruptions; it's advisable to use a multimeter to test voltage stability. Additionally, investigate whether the multimedia control unit is malfunctioning, as this module manages screen operations. DIY solutions include checking wiring diagrams and reinforcing connections, but complex issues like a faulty motherboard require professional repair. For prevention, regularly clearing the cache and avoiding prolonged parking in high temperatures can extend the lifespan.

As a Mercedes-Benz E-Class owner, I've experienced sudden screen blackouts. The solution is quite simple: first, hold the power button on the screen for 10 seconds to force restart the system; this often resolves software freezes. If that doesn't work, exit the vehicle and open the hood to check the fuse box. In Mercedes vehicles, the fuse box is located in the corner of the driver's compartment, with detailed diagrams in the manual. Replacing a blown fuse takes just a minute. Battery health is also crucial; a weak battery can cause screen failures, which may be resolved by charging or replacing the battery. If there's still no response, don't waste time—drive directly to a Mercedes service center where they have professional diagnostic tools. Always prioritize safe driving; if screen functions are unreliable, use manual operations to avoid distractions.
