The reasons for the dash cam not lighting up could be poor line contact, hardware issues, or software malfunctions. Possible causes include the dash cam running out of power, disconnected wiring, damaged camera, or screen damage, all of which require maintenance checks. It's necessary to verify whether the dash cam's power cable is properly plugged in, whether there's any looseness or power interruption. Check if the dash cam's power is on, whether there's an indicator light, and then press the power button to see if the screen lights up. If it doesn't, use a pin to perform a system auto-reset.
Yesterday I encountered a similar issue and it gave me quite a scare. There are several common reasons why a dash cam might not light up, such as power connection problems—maybe the cigarette lighter plug is loose or the USB cable is damaged, cutting off power to the device. It could also be that the internal battery is drained, especially if you haven't turned it off for a long time or the battery is aging. Settings errors are also frequent, like accidentally pressing the screen-off button or a failed firmware update. More seriously, it might be a hardware failure, such as a broken screen or circuit board, which can be quite troublesome. I recommend first checking if the power cable is securely plugged in and restarting the device. If there's no response, try another USB port or cigarette lighter. DIY repairs might save some money, but be careful not to damage other components. Regularly cleaning the plugs and updating the software can prevent many issues. In short, dash cams are crucial for safety in critical moments—don't overlook minor problems.
I've been driving for over 20 years and have encountered many dash cam issues. When it doesn't light up, it really worries me. The main reasons include malfunctioning or loose cigarette lighter sockets, which can cause power interruptions. Aging device batteries are also a factor, especially noticeable during significant temperature changes. Incorrect software settings, such as having auto-sleep mode enabled, can also cause the screen to stay dark. More complex issues involve device damage itself, like faulty lens modules. My advice is to first check all connections to ensure they're secure; try restarting the device, and if that doesn't work, seek professional inspection rather than stubbornly attempting DIY repairs. Dash cams help prevent accident disputes, so address problems promptly - don't wait until an incident occurs to regret it. Make it a habit to check your device's status after parking to avoid surprises.
