Why is the dash cam screen not lighting up?
3 Answers
The reasons for a dash cam screen not lighting up include normal screen-off mode and device malfunction. Normal screen-off: Most modern vehicle dash cams will automatically turn off the screen after recording for a period of time. Don't worry - this is a normal power-saving feature to conserve energy and protect the screen. The camera continues recording in the background, and the screen can be reactivated by pressing any button. Dash cam malfunction: If the device becomes completely unresponsive after screen-off, this indicates a malfunction. Try these troubleshooting steps: Check if the power connector is loose; Inspect wiring for damage or breaks; Press the reset/restart button to see if the device reboots.
I've been driving for many years, and when the dash cam screen doesn't light up, it's often due to a loose power cable or a faulty cigarette lighter socket. You can first check if the cable plug is securely connected and try switching to another USB port. If that doesn't work, it might be a blown fuse—you'll need to open the fuse box under the dashboard and replace it with a spare one. The device itself could also overheat and freeze, in which case a simple restart should fix it. In terms of settings, some models have an auto screen-off feature; press the menu button to see if you accidentally triggered this option. A dash cam is essential for driving—without the screen display, you won't be able to record evidence in case of an accident, which can be quite troublesome. I regularly clean the connector ports to prevent oxidation and avoid faults. If you notice the screen isn't lit while driving, pull over immediately to troubleshoot—don't compromise safety.
I often encounter a black screen with my dash cam, usually due to connection issues or insufficient power. For example, if the power cable is old and broken, replacing it with a new one yourself can solve the problem. Don’t overlook the energy-saving mode settings—it might automatically turn off the screen, so try adjusting the brightness switch. Hardware failures can also occur, such as loose internal screen cables. A light tap might temporarily bring the screen back, but if it keeps turning off, you’ll need a replacement. I remind everyone to fix it promptly—a non-functioning screen not only prevents recording but also affects nighttime parking surveillance. For safety, always keep a spare cable handy and make it a habit to check the power supply monthly. It’s quite frustrating if this happens while driving, so pull over and check immediately.
