The main reason for the display screen not lighting up is a blown fuse causing a power outage. Below is an introduction to the Teana: 1. Overview: The Teana is a mid-to-high-end luxury sedan under Dongfeng's brand. The new Teana adopts Nissan's latest family-style exterior design, with a front face resembling the all-new Sylphy and incorporating Infiniti's dynamic design elements into the body lines, making the vehicle more fashionable and sporty. 2. Configuration: Standard features include pneumatic massage seats, dual-zone independent air conditioning, a rearview camera system, active headrests, six supplemental restraint system airbags, xenon headlights, etc. 3. Interior: It comes with a multifunctional steering wheel, ESC body stability control system, LCD display screen, CARWINGS Intelligent Mobility+ and telematics system.

I encountered an issue with the Nissan Teana's display not turning on, which is quite common. It might be related to power supply problems, such as a blown fuse or low battery voltage, causing the system to fail in supplying power to the screen. You should first check the fuse box, usually located under the hood or near the steering wheel, as described in the manual. If a fuse is blown, try replacing it with a new one yourself. Sometimes, it's just the infotainment system freezing; turning the car key off completely and waiting a few minutes before restarting can help. I remember once after heavy rain, the wiring got wet and short-circuited, causing the screen to stop working, which required a trip to the repair shop. To avoid such issues, refrain from randomly changing settings or forgetting to turn off the lights when parked to prevent battery drain. It's crucial to have these components checked by a technician during regular maintenance.

As someone who frequently tinkers with car infotainment systems, I believe the Altima's display not lighting up could be due to an electronic system malfunction, such as a software conflict causing the system to freeze or crash, requiring a system reboot or software update. Hardware-wise, a damaged screen, loose cable connections, or a faulty motherboard can also cause this issue, especially when driving on bumpy roads where vibrations are more likely to cause problems. Unstable power supply, such as issues with the alternator or battery, may also affect the power delivery. When troubleshooting, first use a diagnostic tool to check for error codes. If none are found, use a multimeter to test if the voltage is normal, and ensure the connectors are not corroded. During daily driving, avoid over-reliance on the screen. If you notice any issues, pull over immediately to consult the manual or visit a professional repair shop—don't wait until the problem becomes more severe.

Having driven a Teana for many years, I know that a non-lit display often stems from daily oversights, such as corroded wiring or loose connectors due to vehicle aging, or mistakenly pressing the function key to turn it off. From a maintenance perspective, it's important to regularly check the battery status and fuses to avoid damage to the electronic system from parking in extreme weather for extended periods. It's advisable to start the car and drive a short distance weekly to help charge the battery and reduce the risk of screen malfunctions. If the screen suddenly goes dark, don't panic—first check if the night mode is activated, dimming the brightness, or try resetting the infotainment system. Prevention is better than repair, so have technicians thoroughly inspect the car's computer components during every maintenance session.
