How to Fix a Non-Illuminating Car Central Control Screen?
2 Answers
Solutions for a non-illuminating car central control screen are as follows: 1. Poor line contact: It is necessary to promptly check whether there is a loose connection in the circuit. A loose connection can cause the central control screen to go black; simply reconnect the loose part properly. 2. Aging power signal line: If the power signal line is aging, try replacing it with a new one. 3. Prolonged screen usage: Extended use of the screen can cause the power supply module to malfunction, leading not only to lag but also to black screens. It could also be due to circuit design flaws. However, issues like abnormal modules and design defects require inspection, repair, or direct replacement at a repair shop.
As a car enthusiast, my first thought when encountering a black infotainment screen is to reboot it, just like when a smartphone freezes. That time during a long drive when the screen suddenly went dark, I panicked and held the power button for 10 seconds. If the touchscreen is completely unresponsive, check if the screen ribbon cable has come loose. Older vehicles are especially prone to wiring degradation, particularly those retrofitted with Android touchscreens where connectors frequently fail. The worst-case scenario is a faulty head unit, but don't rush to replace it - first check if the corresponding 15A fuse in the fuse box has blown. If DIY solutions fail, visit the dealership for computer diagnostics; last time the technician immediately identified a software conflict using the scan tool. Pro tip: always turn off the AC before shutting down the engine - voltage spikes are the biggest enemy of automotive electronics.
