What Causes the Car Screen to Go Black?
2 Answers
If the car screen goes black, you can first try restarting the screen by turning the ignition off and on again. If the issue persists, it is likely due to poor contact in the wiring, and you should promptly check for any loose connections. Wiring Aging: This occurs when the power signal wires have aged. Try replacing them with new ones. If the black screen issue is resolved, it confirms that the power signal wires were indeed the problem. Prolonged Use: Extended use of the screen can cause the power supply module to malfunction, leading not only to lag but also, in severe cases, a black screen. This is often due to circuit design flaws. However, issues like module abnormalities or design defects are beyond personal troubleshooting capabilities and require inspection, repair, or replacement at a service center.
As a long-time enthusiast studying car infotainment systems, there are actually quite a few reasons for a black screen in vehicle displays. I usually start with the simplest checks first: A blown fuse in the fuse box is often the culprit - you can easily tell by gently pulling it out to see if it's burned. Poor contact or aging/damaged signal or power cables could also be the cause, especially on bumpy roads. Then there are software system bugs, like freezing during startup - holding the power button for 10 seconds to force a reboot might solve it. Hardware issues like backlight burnout require disassembly for inspection. Don't overlook temperature effects either - overheating can trigger the screen to automatically shut off for self-protection. I recommend regular electrical inspections for your vehicle to ensure secure wiring connections, which can prevent many unexpected black screen issues and avoid situations where your navigation suddenly fails during a trip.
