The main reasons and solutions for the dashboard not lighting up when the car starts are as follows: 1. Dashboard illumination lamp failure or damage. Solution: Replace the illumination lamp promptly. 2. Dashboard power supply fuse blown. Solution: Replace the fuse. 3. Short circuit in the dashboard power supply wiring. 4. Dashboard motherboard damage or failure. If the fuse issue is ruled out, or if you cannot resolve the problem yourself, you should visit the nearest 4S store or auto repair shop for inspection. Below is some relevant information about the dashboard: The car dashboard is a device that reflects the working conditions of various vehicle systems. Conventional instruments include the speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc.
I once encountered a situation where the dashboard didn't light up, and that time it was because a fuse was blown. I found the corresponding fuse for the dashboard in the engine compartment fuse box, pulled it out, and sure enough, it was melted. Replacing it with a new one fixed the issue. If the fuse is fine, you might need to check if the battery terminals are loose or if the key fob has power, as some cars require a key signal to illuminate the dashboard. Wiring issues are also quite common, especially in older cars where aging wires can cause poor contact. The most troublesome scenario is when the dashboard itself is faulty, which requires professional diagnostic equipment at a repair shop. I recommend not driving without a functioning dashboard, as it's too dangerous to not see your speed or fuel level.
