How to Fix the Black Screen Issue on the Langdong Navigation System?
3 Answers
The solution to the black screen issue on the Langdong navigation system is: 1. Disassemble the navigation unit and remove the circuit board; 2. Use a heat gun to blow air onto the CPU, then wait for it to cool down naturally to resolve the issue. The Langdong's body dimensions are: length 4570mm, width 1775mm, height 1445mm, with a wheelbase of 2700mm, a fuel tank capacity of 50 liters, and a trunk capacity of 473 liters. The Langdong is equipped with a 1.6L naturally aspirated engine, producing a maximum horsepower of 128 hp and a maximum power of 93.8 kW. It is paired with a 6-speed manual transmission. The front suspension type is MacPherson independent suspension, and the rear suspension type is torsion beam non-independent suspension.
When the Langdong navigation screen goes black, I have encountered similar issues several times. Common causes include loose power cables, blown fuses, or a malfunctioning screen itself. As an experienced owner, I would first check the fuse box: locate the fuse corresponding to the navigation system and see if it's blown; if it is, try replacing it with a new one. If the screen remains black, reboot the navigation system: hold down the power button and volume down button simultaneously for a few seconds to force a restart. Sometimes software glitches or update issues can cause this, and upgrading to the latest version may resolve it. Additionally, check if the screen backlight cable is disconnected, especially as it can loosen on bumpy roads. If none of the above works, the navigation unit itself might be faulty, in which case it's time to visit a professional repair shop for diagnostics. Remember, when the screen is black, avoid distractions while driving—use your phone for navigation as a backup to ensure road safety.
The Elantra's navigation screen goes black, and I believe the focus should be on the software aspect. As a car enthusiast familiar with common electronic devices, I've tried restarting the navigation: locate the central control switch, turn off the system, and then restart it. Sometimes the lag will disappear. If that doesn't work, reset the navigation to factory settings by finding the reset option in the settings menu. If the navigation system version is outdated, download the latest update package to fix bugs. Hardware issues can't be ruled out either: check the fuses (the navigation fuse is usually in the second row of the fuse box) or loose wiring connections, but prioritize software solutions first. Additionally, high temperatures in summer can easily cause the system to freeze; let it cool down after parking and try again. During regular maintenance, have a technician inspect the navigation module to prevent issues. Otherwise, a black screen can affect map guidance and increase risks.
