What Causes the Central Control Screen to Not Light Up?

The reasons for the central control screen not working include power supply issues, poor contact in the wiring harness, or main unit failure. Below are detailed explanations: Power Supply Issues: A malfunction in the power supply module can prevent the display from receiving power, naturally causing it not to display. It is recommended to check and replace the power supply module if necessary. Poor Contact in Wiring Harness: Short circuits, open circuits, or loose connections in the wiring harness can cause the display not to light up. It is advisable to check for oxidation or poor contact at the connectors. Main Unit Failure: The display itself may have hardware faults or may have reached the end of its service life. Trying a new display for testing can help determine if the issue is resolved.

I drive quite often, and it's really frustrating when the central control screen doesn't light up. The most common issue is a blown fuse—if the screen suddenly goes completely black along with other electrical failures, it's usually a circuit fuse problem. I always check the fuse box first, located under the steering wheel, to see if the fuse is blown. Another possibility is a loose power cable connection, which can disconnect due to heavy vibrations. Low battery power is also a common issue, especially in older cars. Software crashes aren’t rare either, similar to a phone freezing—try holding the power button for about ten seconds to reboot. When this problem occurs, it affects navigation and air conditioning control, so it’s best to pull over and check immediately to avoid safety risks. Regular maintenance and having a repair shop inspect the wiring can prevent many unexpected issues.

As a hands-on person, I've found that a sudden blackout of the infotainment screen usually stems from a few common issues: a blown fuse is the simplest problem to fix—just replace it. Next could be poor power cable contact, caused by loose plugs or oxidation. A short circuit might also trigger fuse failure. Screen damage is trickier, requiring professional tools to test voltage. I've personally used a test pen to check fuse conditions, but don't force things. If even the reversing camera stops working, it might affect driving assistance functions. My advice: start troubleshooting with the fuse, and consult a mechanic if stuck—safety first. Don't overlook hidden battery aging issues either, as voltage instability can cause system malfunctions.

The central control screen suddenly went black, most likely due to a blown fuse. With decades of driving experience, my first step in such cases is to check the fuses, usually located near the door or engine compartment. Another possibility is loose wiring that got disconnected from bumps. If it's a software crash, holding the power button for half a minute to force a restart might help. A weak battery could also be the culprit—if the engine light behaves abnormally during startup, that's even more suspicious. Don't stubbornly keep driving, as you might miss navigation signals and compromise safety. If simple fixes don’t work, take it to the shop for inspection—saves hassle.
