What to Do When the Car Display Screen Suddenly Goes Black?
2 Answers
If the car display screen suddenly goes black, the solution is: The car owner needs to promptly visit a professional auto repair shop, where professionals can use a diagnostic scanner to connect to the vehicle's onboard computer and read the specific fault location. Then, they can address the issue accordingly. Unprofessional or incorrect installation may lead to screen malfunctions or even burn out internal components, posing certain safety hazards. The main reasons for the black screen are: 1. Poor contact in the connection wiring, causing the screen to lose power and resulting in failure to turn on or a black screen; 2. Aging of the screen's power signal line, leading to inaccurate signal transmission.
From my years of experience studying cars, I can tell you that sudden blackout of the display screen may be caused by several common issues. For example, power supply problems—a blown fuse is a typical cause. First, locate the label corresponding to the display screen in the vehicle's fuse box and try replacing the fuse. If that doesn’t work, check if the power cable connection is loose, as poor contact can easily cause a black screen. Additionally, hardware failure or software crashes in the display itself can also lead to this issue. Restarting the vehicle often helps: turn off the engine, wait for several seconds, and then restart to reset the system. If the problem persists, do not force yourself to continue driving, especially at night or on highways, as a black screen can affect navigation or rearview camera functions, increasing risks. It’s recommended to drive to a professional repair shop as soon as possible for diagnosis with specialized equipment. Avoid disassembling it yourself to prevent further damage to other components.
