The reasons for the car display screen not working are as follows: 1. Wiring issues: (1) Due to vehicle vibration, the wiring ports may become loose and detach. (2) Damaged wiring. (3) 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 devices for car displays: Car display devices are typically LCD screens with external speakers, SD card readers, USB, and Bluetooth functions. 2. Specifications for car displays: Basic specifications for car displays must include dust and shock resistance. In terms of temperature, they must be able to withstand extreme temperature differences from -30°C to +85°C and up to 120°C, as the liquid crystals in the LCD panel may freeze in low temperatures, leading to failure in displaying images or complete destruction of display capability.
As someone who frequently repairs cars, there could be several reasons why the car's display screen isn't working. The most common issue is a blown fuse, which is located in the fuse box under the steering wheel; check if it's melted and replace it with a new one—that might solve the problem. Another possibility is loose wiring, particularly unsecured plugs under the seats or around the center console, which can interrupt the signal. The display unit itself might also be faulty, such as a backlight failure or LCD screen damage, requiring professional inspection. Sometimes, unstable voltage can affect display functionality, especially in older cars or those with additional electronic devices installed. Don’t underestimate this issue—the display controls navigation and rearview cameras, so it's crucial to fix it promptly to avoid distractions while driving. I recommend starting with checking the fuse and power cables before considering a screen replacement.
