Where to Check When the Car's Central Control Screen Doesn't Light Up?

When the car's central control screen doesn't light up, you need to check whether the ribbon cable connection of the central control screen is in good condition. If there is a problem, the ribbon cable should be replaced promptly. Other reasons for the central control screen not lighting up are as follows: Aging of the power signal cable: Another reason the central control screen doesn't light up is the aging of the power signal cable. You can try replacing it with a new one. If the black screen issue is resolved, it indeed indicates a problem with the power signal cable. Failure of the power supply module: If the central control screen remains black after checking the above two scenarios, it may be due to prolonged use causing a failure in the power supply module. This not only leads to lag but also results in a black screen. It requires inspection and repair at a service center or direct replacement.
I remember one time the center console screen suddenly went black while driving, and I was terrified. After parking safely, I first checked the fuse box under the steering wheel to see if the dedicated fuse for the center console had blown. Replacing it with a spare fuse fixed the issue immediately. If that didn't work, I'd check for loose connectors, like unplugging and replugging the wiring harness behind the screen to clean out dust. It could also be a system freeze—holding the power button for over ten seconds to reboot the entire car might help. Sometimes software bugs require a factory reset or an OTA update. Don’t forget to inspect the power and ground wires in case the battery is aging and causing unstable power supply. If you're not confident in DIY fixes or the car is under warranty, just head to the dealership to avoid damaging more components. Get into the habit of regularly cleaning the dashboard to prevent dust buildup and potential short circuits, saving future headaches. In short, take it step by step, stay calm, and prioritize safety—never attempt repairs while driving.
