The reasons for the dash cam screen not lighting up are: 1. Insufficient battery power; 2. System crash or malfunction; 3. Full memory storage; 4. Loose or disconnected cables; 5. Damaged camera or screen. The installation method for a dash cam is: 1. Use tools to secure the dash cam near the rearview mirror; 2. Route the USB cable from behind the glove compartment and tuck the wire behind the glove box; 3. Plug the other end of the power cable into the cigarette lighter. The functions of a dash cam are: 1. To record video images and audio of the entire driving process, providing evidence in case of traffic accidents; 2. To document scenic views during road trips for car owners.
I found that the dash cam screen is not lighting up, and there could be several reasons. It might be a power issue, such as a loose cigarette lighter socket or damaged wiring—my last car had that problem, and unplugging then replugging the connector fixed it. If the charger itself isn’t faulty, the issue could be the dash cam’s battery, especially for older devices where the battery has degraded and needs replacement. The screen itself might also be broken; frequent bumps can loosen internal wiring. Alternatively, it could be a firmware bug—try restarting the device. Also, strong daylight can make the screen hard to see—check if the settings were dimmed by turning off the car lights. For DIY troubleshooting, first try swapping chargers or restarting the device. If the screen still doesn’t light up, visit a repair shop or contact after-sales service. Don’t delay, as missing critical recordings could compromise driving safety.
