What Causes the Dashboard to Go Black?
2 Answers
The reasons for the dashboard going black are: 1. The original car fuse has blown; 2. The navigation button is stuck. The solution is to remove the navigation system and check if the tail fuse of the navigation is blown. If it is, replacing it will solve the problem. It is recommended to use a multimeter to measure whether the B and ACC voltages are normal. If the voltages are normal, then the issue is an internal fault of the device, which requires opening it for repair. The dashboard is a rigid panel or structural component used to install instruments and related devices. It can be categorized by type into screen-type dashboards, frame-type dashboards, channel-type dashboards, and cabinet-type dashboards. The dashboard can come with external lighting, can be attached to a control console, and is available in various forms and sizes. Various instruments can be installed as needed, and different dashboards can be combined into a single unit as required.
This is a common issue, and as a seasoned car repair veteran, dashboard blackouts are nothing unusual. The most frequent culprit is a blown fuse—those tiny ones hidden in the fuse box that burn out when the current spikes. It could also be a dead battery, loose connections, or corroded terminals, so it's worth checking if the battery voltage is normal. Dashboard failures themselves are quite common too, like burnt-out internal bulbs or aging circuitry, especially in older cars after rain exposure. Another possibility is a loose sensor connection disrupting the entire system's power supply. The most nerve-wracking part is losing speed visibility during a blackout, which is extremely dangerous on highways—pull over immediately to diagnose. My advice: first consult the manual to locate and replace the fuse. If that doesn’t work, tow it to a professional shop for circuit diagnostics—never underestimate this problem.
