What to Do When the Rearview Camera Screen Goes Black?
1 Answers
Check if the car's original fuse has blown. If the fuse is blown, simply replace it. Inspect whether the navigation buttons are stuck, as stuck buttons can also prevent the system from turning on. If you're skilled with hands-on tasks, you can remove the navigation unit to check if the tail fuse of the navigation system is blown. If it is, replace it. A black screen on the rearview camera is often due to poor line connections. It's necessary to promptly inspect the wiring and the connection points installed in the vehicle to see if there are any loose connections. If there are loose connections, it can naturally lead to intermittent functionality of the rearview camera or even a complete black screen. In such cases, simply securing the loose connections properly should resolve the issue. Of course, it could also be due to aging of the video power cable. Trying a new power cable might solve the black screen issue, indicating that the problem indeed lies with the video power cable. If, after checking the above two scenarios, the rearview camera still shows a black screen, it's likely due to prolonged use of the rearview camera, resulting in poor chip photosensitivity. This not only causes snowy images but, in severe cases, leads to the black screen issue we're discussing today. Additionally, it might be due to inherent defects in the car's circuit design. However, issues like chip abnormalities and design defects are beyond our capability to fix and require inspection, repair, or replacement at a professional repair shop. In fact, various malfunctions in the rearview camera are largely related to its installation process, as this involves dealing with relatively complex wiring. Therefore, if we really need to replace the rearview camera, it's best to leave it to professionals. Otherwise, unprofessional or incorrect installation (of the wiring) could not only cause malfunctions like the black screen issue we're discussing today but also pose potential safety hazards. Of course, if you're already very familiar with this process, doing it yourself is also an option.
