Why is the Mercedes-Benz smart screen not lighting up?
2 Answers
The reasons for the screen not lighting up include damage to the dashboard illumination light; a broken power supply wire for the dashboard; or a blown fuse for the dashboard power supply. Inspection: First, check the dashboard power supply fuse and replace it if blown. Disassemble the dashboard—the illumination lights are located at the back of the dashboard—and replace any non-functioning lights. If only individual lights are not working, it indicates that the fuse and wiring are fine. Advantages of the smart car: Fuel-efficient and easy to handle; spacious and comfortable interior; frameless windows are practical and stylish; the trunk features a dual-opening design for ample storage space; the rear wiper activates automatically when the windshield wiper is turned on or when reversing; integrated seat design; full underbody protection; U-shaped torsion beam rear suspension. The higher seating position provides a broad field of vision.
The issue of the Mercedes-Benz Smart screen not lighting up is quite common. I think it's best to start with the simplest checks first. Power supply problems are often caused by a blown fuse—just find the fuse box under the dashboard, use a tool to pull out the fuse and check if it's blown. If it is, replace it with a new one and test. Wiring connection issues are also frequent, especially loose or short-circuited plugs behind the screen, so inspect whether the plugs and wiring harness are secure. Software glitches can also be a factor; the screen may go black during a system crash. A simple solution is to turn off the vehicle's power, wait a few minutes, and then restart. Hardware damage is less common, but if the screen itself is cracked or burnt out, replacement is necessary. Based on my experience, I recommend prioritizing checks for fuse and connection issues. If you can't handle it yourself, take it to a professional shop for inspection—don't tinker blindly, and ensure safety.
