Why is the Mercedes-Benz smart screen not lighting up?

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.

My Mercedes-Benz Smart's screen suddenly went black once. I immediately checked the fuse box and found that the screen fuse had blown. After easily replacing it, the screen lit up again. Loose wiring can also cause similar issues, so it's important to check if the connectors are properly seated and not wobbling. If the software freezes, turning off the engine and restarting it after a while might restore normal function. It's rare for the screen itself to be faulty, but if the car has been in a collision, that could be a potential issue. Personally, I recommend starting with these simple self-checks to save money and time. If the problem persists, don't hesitate to visit a 4S shop to avoid disrupting daily use—after all, driving without a screen for navigation can be quite inconvenient.

If your modified Smart's screen suddenly goes dark, it's most likely due to loose wiring harness connections or power supply conflicts. For factory issues, it could be a blown fuse—just check and replace it. However, during modifications, rough wiring can easily cause short circuits or voltage instability. Check if the connection points are loose and try resetting the system. Based on my car modification experience, properly securing the wiring harness is crucial. If you can't fix it, take it to a modification shop to rewire it—don't complicate the issue to avoid future troubles.

The unlit screen of a Mercedes-Benz Smart should not be ignored as it provides crucial navigation and warning information. A malfunction significantly increases driving risks. Main causes include blown fuses, wiring faults, or system crashes. Priority should be given to replacing fuses and testing circuits, while professional technicians should inspect software issues - a restart may resolve them. Delayed repairs could lead to accidents; it's advised to pull over immediately for inspection or repairs upon discovery. Safety comes first, prevention is key.
