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.
