What is the reason why the dash cam does not display images?
2 Answers
The dash cam not displaying images is mostly due to power issues or machine malfunctions. It is recommended that users check the power supply. Since the dash cam plug is always inserted into the interface, when the vehicle is moving, the vibration and shaking of the car body can inevitably cause the plug to loosen. Re-plug the plug and observe if there is any response on the screen. If there is still no response after multiple attempts, the cause of the plug loosening can be ruled out. Relevant information about the dash cam is as follows: 1. Introduction: A dash cam is an instrument that records images, sounds, and other related information during vehicle travel. 2. Function: After installing a dash cam, it can record the entire process of the car's travel in video images and sound, providing evidence for traffic accidents.
I remember my dashcam screen went black while driving, which was quite a headache since I'm used to checking it every time I start the car. First, I checked the power cable connection since loose plugs or faulty cigarette lighter sockets are common issues, and aging charger heads can cause unstable power supply. Then it occurred to me that the storage card might be full—short card lifespan or formatting errors can prevent image display. I cleared old video files and tried a FAT32-formatted card. Dirty lenses are another potential problem, so I gently wiped the glass surface with a soft cloth to see if it improved. Software bugs shouldn't be overlooked either; I performed a long-press reset to reboot the system, which usually fixes the issue. If none of these work, it might be a screen malfunction or internal hardware damage, requiring professional repair to avoid compromising driving safety. A dashcam without video feed is unacceptable—lack of evidence during accidents puts you at a disadvantage. That's why I recommend developing habits of regular checks and backups.
