The reasons why the center control display screen of Hyundai Elantra does not light up: 1. Press and hold the power button for 5 seconds, but the screen does not light up and the power indicator light (green light) does not light up or lights up and then immediately turns off, indicating that the product battery is dead; 2. Pull out the display screen's ribbon cable and reinsert it to secure it. If the display screen lights up, it means the display screen ribbon cable connector was loose; 3. If it happens occasionally, it is normal because when starting the car, the instantaneous power is used for ignition, resulting in lower voltage. The Elantra is a global model of Hyundai that was first launched overseas, equipped with a 1.6L engine and a 1.8L engine. In terms of body size, the Elantra has a length, width, and height of 4570mm, 1800mm, and 1440mm respectively, with a wheelbase of 2700mm.
The central control screen of the Hyundai Elantra suddenly went dark, and I suspect it might be a blown fuse issue. From my experience, many car owners encounter this situation due to fuse problems. It's located in the fuse box and melts to protect the circuit when the current is too high. Another common cause is a malfunctioning backlight in the screen itself or poor contact—if the connector is loose, it can easily lead to a black screen. A short circuit in the wiring is also a suspect, such as aged wires or damage caused by rodents. If the car battery has insufficient power or unstable voltage, it can also cause the central control screen to stop working.
After the central control screen goes dark, you should first turn off the engine and restart it to see if it recovers. If you want to inspect it yourself, refer to the fuse location diagram in the user manual and use a test pen to check if it's blown. Of course, if the issue is complex, it's best to go to a professional repair shop promptly to avoid affecting functions like the rearview camera or navigation, ensuring a calm and safe drive.
Although this is a minor fault, ignoring it can cause delays. Regular maintenance, such as checking connector tightness and moisture-proofing, can help reduce such troubles.
When the central control display screen is unresponsive, common root causes include issues with the electrical circuit. A blown fuse is the most frequent culprit, often due to overload or instantaneous current surges. In the Hyundai Elantra, the fuse box is typically located under the driver's seat, requiring the removal of a small cover to inspect the corresponding fuse's condition. Poor wiring connections should not be overlooked either—the connector linked to the screen may have become loose or oxidized, leading to unstable contact. Hardware failures in the screen, such as a malfunctioning internal backlight tube or damaged display module, can directly cause the screen to go completely black. Additionally, issues with the vehicle's power system, like an aging battery causing significant voltage fluctuations, can prevent the central control screen from powering on. When the screen remains dark, I've tried restarting the vehicle multiple times; sometimes, it's just a software freeze that resolves after a few reboots. Related multimedia functions like the radio or Bluetooth may also malfunction, which can be quite frustrating for the driving experience. It's advisable to start with simple troubleshooting steps, such as checking the fuse and using a multimeter to test circuit continuity. If a complex fault is identified, don't delay—take it to a 4S shop for repair, as the central control system manages critical functions like air conditioning and settings panels. Prolonged neglect could lead to a cascade of other minor electronic issues.
