What to do if the Mercedes-Benz C-Class screen suddenly goes black?

If the Mercedes-Benz display screen is not working, you can first try restarting the vehicle - turn off the engine and then restart it to see if this resolves the issue. If successful, it may just be a temporary system freeze, which is not a major problem. If the screen still doesn't display, it could indicate a system or hardware malfunction, in which case it's recommended to visit an authorized 4S dealership for repair and servicing. Below is an introduction to Mercedes-Benz vehicles: 1. Brand Introduction: Mercedes-Benz is a world-class luxury automotive brand, considered one of the most premium car brands globally. It is renowned for its perfect engineering, rigorous quality standards, innovative capabilities, and a series of classic coupe models. 2. Founding History: Mercedes-Benz is a world-famous German automobile brand established in 1900, headquartered in Stuttgart. The company was founded by Karl Benz and Gottlieb Daimler. Mercedes-Benz is internationally known for its high-quality, high-performance automotive products. In addition to premium luxury cars, Mercedes-Benz is also one of the world's most famous manufacturers of buses and heavy-duty trucks.
The infotainment screen in my Mercedes-Benz C-Class suddenly went black last week, which really freaked me out. I tried the simplest solution: parked the car, turned it off, locked the doors, waited ten minutes, and restarted – miraculously, the screen came back to life. Later, a friend at the dealership told me this is usually caused by a temporary system freeze, and a power cycle can fix it. But if restarting doesn't work, it might be a loose screen cable or motherboard failure. I also have a trick – holding down the volume knob and phone button simultaneously for 15 seconds forces a reboot, which works wonders for software crashes. As a last resort, check the fuse box (the small compartment near the driver's left foot) for fuse F37. However, Mercedes' electronic systems are complex, and DIY tinkering can easily cause damage. In the end, I took it to the shop for a full diagnostic and got a new main unit installed, which completely solved the issue.
Last month, while driving my child to school, the screen suddenly went black, which was quite alarming at the time. I immediately called Mercedes-Benz Roadside Assistance, and they advised me to turn off the engine, wait for three minutes, and then power it back on, but unfortunately, it didn’t work. The repair technician later told me that screen blackouts in the Mercedes C-Class are often due to software crashes—holding down the volume button and the menu button simultaneously can force a reset. Another common cause is overheating protection, especially after prolonged exposure to the sun in summer. If the screen is completely unresponsive, check the No. 47 fuse in the fuse box under the driver’s seat; use small tweezers to pull it out and see if it’s blown. However, I should remind you that post-2018 Mercedes models use the MBUX system—if it freezes, don’t rush to pull the fuse. Instead, try connecting to a mobile hotspot to let the system update automatically. If all else fails, it’s best to consult a professional, as dismantling the center console yourself might trigger the anti-theft lock.
