What Causes a Dash Cam to Power On But Not Display on Screen?
2 Answers
If the dash cam screen remains dark after powering on, it could be due to the screen saver function being activated by default, a blown fuse, poor wire contact, hardware issues, or software malfunctions. Additional relevant information is as follows: 1. Introduction: A dash cam is a device that records images, sounds, and other related data during vehicle operation. After installation, it captures the entire driving process in video and audio, providing evidence for traffic accidents. 2. Screen Saver: The dash cam display not lighting up may indicate that the screen saver function is enabled by default. Many dash cams include this feature to conserve battery power and prevent screen glare from affecting driving. Once the screen saver is set, the dash cam screen turns off during recording, appearing as if it is not powered on, but the recording continues normally in the background.
I've been driving for fifteen years and have encountered the issue of a dash cam not powering on several times. Most of the time, it's due to a loose power cable or a blown fuse. Once, when using the cigarette lighter for power, the screen wouldn't turn on because the port was worn out and had poor contact—replugging it tightly fixed the issue. Power supply problems are the most common; check if the cable is damaged or if the socket has power, and try replacing the dash cam fuse in the car's fuse box. The screen itself might also be faulty, such as the backlight being damaged from prolonged use in high temperatures, requiring repair or replacement. Another often-overlooked issue is settings—some dash cams have an energy-saving mode that turns off the screen automatically, and pressing the settings button upon startup can turn it back on. Neglecting this could stop the recording function, leading to a lack of evidence in case of an accident, so perform a self-check or visit a professional shop promptly.
