What Causes the Black Screen Issue in the Langdong Navigation System?

[ArthurMarie]

The black screen issue in the Langdong navigation system is primarily caused by a virtual soldering phenomenon on the CPU of the circuit board. Here are some relevant details about the Langdong: 1. Interior: The interior features more highlights, such as the auto-dimming rearview mirror, which not only enhances driving safety but also integrates the latest BlueLink human-vehicle interaction system. This system functions similarly to the familiar General Motors OnStar or Toyota G-Book. Based on previously disclosed information, this feature is integrated in the form of a traditional rearview mirror in the 1.6DLXAT (1.6L top trim) model. 2. Powertrain: Equipped with a 1.6L γ engine and a 1.8L Nu engine, the Langdong has firm suspension, minimal body roll during high-speed cornering, and good body stability. However, it has blind spots in visibility and noticeable road noise. The overall handling leans towards sportiness, but comfort is relatively average. Exterior: More in line with mainstream aesthetic preferences.

I've encountered many similar situations before. The black screen on the navigation system could be caused by several common reasons. First, it might be a software system crash. The Android-based system in the Langdong navigation sometimes freezes due to insufficient memory or bugs. You can try finding the restart option in the settings menu or restart the vehicle after parking. Second, it could be a hardware issue like a broken backlight, which is common in hot weather or aging vehicles. You'll need to check if the display is functioning properly. Third, it might be a power supply problem, such as a blown fuse or loose wiring related to the navigation system. Open the fuse box located on the driver's side and check the corresponding 15A or 20A fuse. I recommend starting with a simple reset first. If that doesn't work, take it to a professional shop for diagnosis promptly, as this affects driving navigation. Fourth, poor usage habits, such as frequently switching apps causing system overload, can be prevented by regularly clearing the cache. Fifth, unstable voltage or abnormal alternator operation can cause the screen to lose power. Use an OBD tool to check the voltage. For safety, once the screen goes black, use your phone as a temporary navigation replacement.

My Elantra's navigation screen has gone black a few times before, and each time was quite frustrating, but I managed to find the cause. Once, it froze after a software update, and I fixed it by holding the navigation power button for ten seconds to restart. Another time, during summer, the screen turned off due to overheating after parking in the sun, and it only came back on after the car cooled down. There was also an instance when a fuse blew, and replacing it for 20 yuan solved the problem. I’ve learned my lesson now: avoid running too many apps simultaneously on the navigation system to prevent crashes; regularly check system settings to ensure the software is up to date; and if the screen goes black, immediately pull over safely and attempt a soft reboot. If the black screen persists, don’t force open the system to avoid damaging more components—contact a 4S shop or a reliable repair center right away. They’ve also encountered cases where the display motherboard was faulty, with repair costs ranging from a few hundred to a thousand yuan.

As a tech-savvy car enthusiast, navigation screen blackouts are mostly caused by underlying system issues. The Lantra's navigation runs on a customized Android system, where app conflicts or resource exhaustion can lead to screen freezes. Solutions include entering engineering mode for a factory reset or updating the firmware. On the hardware side, potential causes could be backlight aging or poor ribbon cable contact, which may disconnect due to vibrations on rough roads—check if connectors are secure. Large voltage fluctuations from the power supply can trigger protective system shutdowns; verify if input voltage stays around 12V. For prevention, back up navigation data to avoid loss during resets and minimize running multiple apps simultaneously. If hardware is damaged, replacing the LCD module isn't overly expensive but time-consuming. If this happens while driving, stay calm, slow down, and find a safe spot to address the issue.
