What causes the electric car screen to not light up and fail to start?

[VonRobert]

When the electric car screen does not light up and fails to start, it may be due to a faulty light-emitting diode (LED), poor contact in the connectors, or an open circuit in the dashboard wiring. Below are detailed explanations for each possible cause: 1. Poor contact in the connectors: If there is poor contact in the connectors, the instrument panel may not receive power properly, resulting in the lights not turning on. Solution: Locate the area with poor contact and reconnect the connectors to resolve the issue. 2. Faulty light-emitting diode (LED): If the LED is faulty, it will directly cause the instrument panel lights to not illuminate. Solution: Replace the faulty LED to restore functionality. 3. Open circuit in the dashboard wiring: If there is an open circuit in the dashboard wiring, the instrument panel may not receive power, leading to the lights not turning on. Solution: Identify the location of the open circuit and repair the fault to resolve the issue.

I've been driving electric vehicles for several years and often encounter situations where the dashboard screen doesn't light up during startup. Experience tells me that this issue is mostly caused by blown fuses or battery aging. Especially when the car has been parked for a long time without use, self-discharge of the battery leads to insufficient power; after powering on the screen, it just goes black, and the entire system fails to start. I had an old car that behaved exactly like this—later, I started regularly checking the fuse box and found that small fuses were prone to blowing. Replacing them myself was very cheap. Another common cause is corrosion or loosening of wiring contact points—this happens when the car is exposed to humid environments for extended periods. I must remind everyone: don’t underestimate this seemingly minor issue; if a short circuit leads to bigger electrical problems, the car could be completely immobilized. So during every maintenance session, I take a moment to clean the wiring ports and check the fuses—it only adds a few minutes per year. Early detection and early action make the car more reliable. Still can’t solve it? Don’t push your luck; seeking help from a professional shop is the safest bet.

As a guy who loves tinkering with electric cars, I've found that a black screen failing to start is often a minor glitch. For instance, a blown fuse or insufficient system power due to a drained battery—just check the fuse box location and replace it according to the manual. It could also be a short circuit or a loose display connector; pop open the dashboard cover to see if any connectors have come loose and tighten them. I once fixed it myself, saving over a hundred bucks in labor costs. But beware: don’t DIY complex issues like a damaged ECU control module, as you might accidentally harm other components. It’s good practice to maintain habits like keeping the battery fully charged and regularly cleaning dust from the car’s circuitry. This prevents small issues, making the car more durable and reliable. When facing similar problems, stay calm and start with simple checks—nine times out of ten, you’ll solve it.

Back when my car was new, I encountered a complete blackout of the electric vehicle screen during startup, which scared me into thinking the car was totaled. A friend pointed out it could be due to a blown fuse or a dead key fob causing signal loss. I checked the manual, located the fuse, replaced it, and sure enough, the car started. The lesson here is simple: Battery drain is a common culprit; leaving the car unused for a few days can trigger this. Another possible factor is key fob sensor failure—try replacing its battery. As a beginner, learning basic checks can prevent panic. Remember: Don’t rush to call a tow truck; first inspect these minor issues. Quick fixes like these won’t disrupt daily commutes.
