What Causes the Car's Central Control Display Screen Not to Light Up?
3 Answers
The reasons why the car's central control display does not light up are as follows: 1. The central control screen system is frozen. Abnormal operation of system components due to high or low temperatures can cause this situation. It will recover when the vehicle temperature becomes suitable. 2. After starting the vehicle, the central control is considered to be turned off. At this time, just press the power button to turn it on. 3. The fuse of the vehicle's central control screen is broken. Without a power supply, it will not light up. Replace the fuse in the engine compartment fuse box. Solutions: 1. First, check whether the power supply of the display screen is normal. If the power supply is abnormal, replace the power supply module. 2. Then check whether the contact of the cable is good. If there is a problem, replace the cable. 3. Check whether the display screen is damaged. Replace the display screen for testing. If it returns to normal, the display screen is damaged. If it is the same, the power supply is normal, and the cable contact is good, check whether the mainboard video output is normal.
I've been in the automotive repair industry for over twenty years and have encountered the issue of a non-functional center console display countless times. The common causes are blown fuses or loose wiring connections. When the vehicle experiences bumps, connection points may become detached, especially in older models or modified vehicles where unstable power supply lines can cause screen power failure. Software malfunctions are also frequent - when the system freezes, a hard reset is often needed: turn off the engine, wait five minutes, then restart, which sometimes resolves the issue. Physical screen damage is another possibility, such as aging internal LCD components or water-induced short circuits. My recommendation is to start with the simplest solution: check the fuse box for the corresponding marked fuse, replace it, and test again. Never ignore this issue as it affects navigation, music control, and even air conditioning adjustment, creating inconvenience and potential danger while driving. Regular maintenance and circuit inspections can prevent such problems. If the issue persists, seek professional repair immediately to prevent minor issues from becoming major ones.
Last time my car screen suddenly went black, I panicked and pulled over to the roadside. After consulting a mechanic friend, I first checked the fuse box near the driver's side. The one labeled 'display' had blown, and replacing it fixed the issue. Sometimes it's just a simple short circuit or loose plug; pulling the wire behind the center console might also help. For software issues, a reboot is needed: turn off the engine, remove the key, wait a few minutes, or disconnect and reconnect the battery's negative terminal. Voltage fluctuations, like a weak battery, can also trigger this problem. Daily driving should avoid water splashes or randomly adding electronic devices to reduce interference. A dark screen makes the journey more stressful, especially at night when visibility is poor—stop safely before handling it. Regularly wash the car and clean the ports to prevent poor contact. If all else fails, have a professional shop check the motherboard or update the firmware.
