The reasons for the car display screen not working are as follows: 1. Wiring issues: a. Due to vehicle vibration, the wiring port may become loose and detach. b. Damaged wiring. c. Poor wiring contact. 2. Display screen issues: The display screen itself may be damaged, causing it to fail to display, requiring further inspection and repair. Additional information: Introduction to car displays: 1. Display equipment of car displays: Car display equipment is usually an LCD screen with external speakers, capable of reading SD cards, USB, and Bluetooth functions. 2. Specifications for car displays: The basic specifications of car displays must include dust-proof and shock-proof functions. In terms of temperature, they must be able to withstand high and low temperature differences ranging from -30°C to +85°C and 120°C, as the liquid crystal in the LCD panel may freeze in low-temperature environments, leading to the inability to display images normally or complete destruction of display capability.
When the car's display screen suddenly goes dark, the first thing that comes to mind is a power issue, such as a blown fuse or unstable battery voltage causing the screen to lose power. You can pop the hood and check the fuse box, looking for the display screen fuse to see if it's blown. Another possibility is loose or damaged wiring, like the cables connecting the screen to the mainboard—try wiggling the connectors. Software glitches are also common, especially in systems with navigation that may freeze; try turning the car off and restarting it to refresh the system. Don’t ignore this issue, especially on highways where losing speed display poses a major safety risk—get to a repair shop promptly to scan for trouble codes with a diagnostic tool. Additionally, physical damage to the display itself, such as screen aging or water ingress, requires professional evaluation and potential replacement to avoid long-term impacts on driving enjoyment.
A non-functional display is quite annoying. I suspect software crashes or incorrect settings are common issues. You might have accidentally pressed the wrong button and turned off the display, or conflicts occurred after a system update, causing it to freeze. Try locating the reset button on the center console to reboot. On the hardware side, a faulty LED backlight or motherboard issue can cause a black screen. Check for loose connections yourself and use a multimeter to test power supply current. External factors like moisture infiltration or impact shocks should also be noted, as they can cause short circuits, overheating, or screen shutdowns. The impact is significant—increased blind spots while reversing can easily lead to accidents. So, quickly identify the root cause and, ideally, take the car to a professional shop for a computer scan and repair to avoid damaging the hardware yourself.
