What Causes a Dash Cam Not to Light Up?
2 Answers
Reasons for a dash cam not lighting up include normal screen-off and device malfunction. Specific causes are as follows: Normal Screen-Off: Currently, most dash cams will automatically turn off the screen after recording for a period of time. Don't worry—this is a normal operation to save power and protect the screen. In fact, the dash cam is still recording video in the background. Simply press the screen button to light it up again. Dash Cam Malfunction: If the dash cam does not respond after the screen turns off, it indicates a malfunction. You can troubleshoot using the following methods: check if the power interface is loose; inspect the dash cam wiring for damage or breaks; press the reset or restart button on the dash cam to see if it reboots.
As a veteran driver with decades of experience, a dash cam not lighting up is nothing new. Let's talk about the common causes. Power issues are the most frequent—loose cigarette lighter plugs or blown fuses can cut off the power supply. The screen might freeze or the backlight might turn off, making it appear as if it's not working. A full or corrupted memory card can cause the device to stop functioning without any warning. Hardware failures, such as a damaged camera, can also be problematic. Sometimes, it's a firmware bug that requires an update. The key point is the significant safety risk—without a dash cam, you might lack crucial evidence in case of an accident, which could be a huge loss. Regularly check if the power connection is secure, try restarting the device, and clean up the memory card to ensure sufficient space. Overheating due to high temperatures inside the car is also common, so avoid parking in direct sunlight. Address the issue promptly—ensuring driving safety is what truly matters.
