What is the reason for the dash cam not displaying images?

The dash cam not displaying images is mainly due to power issues or machine failure. Check if the power indicator light is on. If the indicator light is not on, you need to check the power connection; if the indicator light is on, it indicates a machine failure, which could be a lens issue, display problem, or machine damage, requiring repair. If the dash cam is an original factory-installed device, you can go to the car's 4S store for repair; if the dash cam is an aftermarket installation, you can go to the store where you purchased the dash cam for repair. When choosing a dash cam, it is necessary to select one with good camera clarity and night shooting capability. High definition is determined by the main control chip of the dash cam, so you need to pay attention to the image processing solution of the main control chip. The dash cam should have sufficient storage space to achieve long-term effective recording. The camera's shooting angle should be larger to comprehensively record the surrounding situation of the vehicle, but it should be noted that the lens angle should not be too exaggerated to avoid distorted images.
I've encountered the dash cam black screen issue several times, mainly need to check from three aspects: lens, power supply, and storage. The lens might be covered by dust or oil film, especially after rain when mud easily splashes on the rearview mirror position; the power cable could be loose, as the old-style spring clips in cigarette lighter sockets tend to have poor contact after long use; if the SD card isn't properly inserted or is damaged, it can also cause black screen - it's best to use genuine memory cards. Once I found my dash cam froze due to overheating, the body became scalding hot after summer sun exposure, so I recommend choosing models with heat dissipation design. When troubleshooting, first clean the lens, then unplug and replug the power cable to restart, finally format the memory card.
