Why is the LCD screen in the middle of the dashboard not lighting up?
2 Answers
The reasons why the LCD screen in the middle of the dashboard does not light up are as follows: 1. The vehicle dashboard is malfunctioning. 2. The plug behind the vehicle dashboard is loose, the circuit is short-circuited, or damaged. 3. The sensor that adjusts the small LCD screen on the dashboard is malfunctioning. 4. The power signal line is aging. Additional information: Introduction to the car display screen: The car display screen not only provides information such as navigation, reverse camera images, and vehicle fuel consumption for viewing, but also offers a variety of multimedia entertainment systems for operation, providing convenience to the occupants and enhancing the interior aesthetics. If the car display screen fails, it will cause a lot of inconvenience to the driver. Therefore, if there is a problem, it should be checked and repaired in time.
Once I encountered a situation where the dashboard LCD screen went completely black, which made me a bit nervous because I couldn't see the speed or warning lights while driving, posing a serious safety risk. When checking the cause, I found that a fuse might have blown. These are located in the fuse box—try replacing the one related to the dashboard. If that doesn’t work, it’s likely due to poor wiring contact or a short circuit, such as from aged wires or rodent damage. Modern cars have complex electronic systems, so a faulty control module could also cause unresponsiveness. Screen damage itself is rare but can happen due to impact or aging. The solution is to safely pull over first to ensure it doesn’t affect driving, then get a professional inspection as soon as possible. For prevention, have a technician check the wiring and fuses during regular maintenance—don’t wait until a major issue arises.
