What Causes the Civic Display Screen to Go Black and Not Light Up?
2 Answers
Civic display screen black and not lighting up reasons introduction: The car screen going black may be caused by power supply, wiring, or dust contact issues. In such cases, you can visit a 4S shop to restore factory settings or use a decoder to connect to the vehicle's computer to read the specific fault location, then address the issue accordingly. Below are related introductions: 1. Fault phenomenon: The malfunction of the central control screen is largely related to its installation process, as this task involves dealing with relatively complex wiring. Therefore, if you really need to install an additional screen, it's best to leave it to professionals. Otherwise, if the (wiring) installation is unprofessional or incorrect, it may lead to screen malfunctions, or even burn out components inside the car, posing certain safety hazards. 2. Circuit design flaws: Issues with module abnormalities and design flaws are beyond the scope of self-resolution and require inspection, repair, or direct replacement at a repair shop.
As a Civic owner, I often encounter similar issues. A black or unlit display screen can stem from multiple hardware failures. For instance, the screen itself may have aged or malfunctioned, especially the large display in higher trim models which is prone to burning out; loose wiring connections can cause intermittent power loss on bumpy roads; a crash in the control module software, as Civic's system updates sometimes introduce bugs leading to freezes; or power supply issues, where a depleted battery or unstable voltage can affect performance. It's recommended to first try turning off and restarting the vehicle, waiting a few minutes before starting again to see if the screen recovers. If that doesn't work, check the fuse box to see if the display's corresponding fuse has blown. Remember not to tamper with the wiring yourself—modern car electronics are complex, so it's best to take it to a 4S shop for diagnostic computer testing to avoid damaging other components.
