What to Do When the Mazda Display Screen Goes Black?
2 Answers
There are many possible causes for a black screen, such as power supply issues, wiring problems, or poor contact due to dust. You can try restoring the factory settings or using a computer to troubleshoot. If the problem persists and the vehicle is still under warranty, seek warranty service. If it's out of warranty, take it directly to a 4S shop for repair. Below are some common issues and their causes for the central control screen: 1. No response when pressing buttons on the touchscreen, unable to control: This is a "drifting" phenomenon of the touchscreen. Please re-enter the touchscreen settings page to recalibrate the touch range. 2. The touchscreen displays content, and buttons respond when pressed, but control cannot be achieved: (1) The RFID of the touchscreen does not match the RFID set in the host program; (2) The ID of the wireless receiver does not match the ID set in the host program; (3) The wireless receiver is out of range.
Last time I encountered the issue of the display screen going black, I tried the method taught by the car enthusiast group: after turning off the engine, press the volume button on the steering wheel for 30 seconds to force restart the infotainment system. If it still doesn't light up, check if the corresponding fuse in the fuse box has blown. Pull out the small blue 10A F59 fuse; if it's melted, you'll need to spend a few dollars at the auto parts store to get a new one. Most of the time, it's either a software freeze or a blown fuse. However, if the screen has no backlight at all and the air conditioning buttons malfunction while driving, it might be that the wiring harness connector in the rear compartment has been loosened by heavy items in the trunk. Also, during the recent rainy season, be careful not to let the drainage holes under the windshield get clogged, as accumulated water can backflow into the dashboard and damage the circuit board, which would be a real hassle!
