What are the reasons for the non-illumination of the Hongqi H5 center control screen?
3 Answers
Hongqi H5 center control screen does not light up for the following reasons: Poor line contact: The phenomenon of the car center control screen going black is largely due to poor line contact, and it is necessary to promptly check whether there is a phenomenon of virtual connection in the lines. Aging power signal line: The phenomenon of the car center control screen going black may also be due to the aging of the power signal line.
The central control screen of the Hongqi H5 is not lighting up? There could be several reasons for this. Having driven a Hongqi for a while, sudden screen blackouts are quite common. It might be a hardware issue, like aging internal components or damage from impact; or it could be power-related, such as a blown fuse—check the fuse box under the driver's seat and try replacing it. On the software side, the system might have crashed, causing it to be unresponsive—try restarting the infotainment system by holding down the power button. Connection issues, like loose plugs or corroded wiring affecting signals, could also be the culprit. Additionally, frequent power cycling or software conflicts after modifications might cause malfunctions. When driving, avoid sudden starts and stops, and keep the system updated to minimize issues. It's recommended to troubleshoot basic issues first; if that doesn’t work, take it to a 4S shop for repair promptly to avoid affecting navigation and safe driving.
Last time I encountered a non-functional screen on my Hongqi H5, it turned out to be a blown fuse. I opened the fuse box near the engine hood, located the corresponding fuse for the central control, and saw it was burnt black. Replacing it with a new one fixed the issue immediately. It could also be due to insufficient battery power causing unstable power supply during vehicle startup, or loose wiring with unsecured connectors. If the system overheats and crashes, a forced restart usually works. Be cautious with vehicle modifications and aftermarket installations as they can cause problems. I make it a habit to regularly check for wire aging and avoid prolonged exposure of the screen to high temperatures to extend its lifespan. Don't take such issues lightly as they can affect the reversing camera and AC control. It's best to have a professional mechanic address the problem promptly.
