Why did the dash cam suddenly stop lighting up?
3 Answers
Reasons why the dash cam suddenly stops lighting up: 1. The dash cam is out of power: If the dash cam is used continuously for a long time, it will reduce the battery life, and the screen will naturally go dark when the battery is depleted; 2. The dash cam's own screen saver: Similar to a computer screen, some dash cams will automatically turn off the screen to save power if not operated for a long time; 3. The dash cam has crashed: If the internal system of the dash cam becomes disordered, it can easily cause a crash; 4. The dash cam is damaged: If the dash cam is damaged due to a traffic accident or human factors, it is necessary to ask a professional to repair or replace it with a new one.
The dash cam suddenly turned off, and I've experienced this several times. The most common issue is power connection problems—the cigarette lighter plug might be loose or the power cable could be pinched and broken by the seat. First, try reinserting the plug firmly to see if it lights up. Sometimes a blown fuse can also cause this; locate the dash cam's corresponding fuse in the car's fuse box, check it, and replace it if necessary. Using a multimeter to measure voltage is more accurate. If the built-in battery is old and can't hold a charge, it might suddenly lose power. A full or corrupted memory card can also cause a black screen—try removing it, formatting it, or replacing it with a new one. If the device's software crashes, look for a reset button and hold it for a few seconds to restore functionality. Safe driving is crucial, and a broken dash cam means no evidence in case of an accident, so it's best to address the issue promptly. Regularly inspect cables to prevent damage from debris, and develop good habits to avoid problems before they arise. After all, since the car is used daily, small issues can quickly escalate into bigger troubles.
There are several possible reasons why a dash cam may not light up. Firstly, power supply issues are the main factor—check if the cigarette lighter socket is receiving power and use a tool to test the voltage for normalcy. Secondly, hardware failures such as a depleted battery or damaged circuit board could be the cause. Additionally, memory card problems can lead to a black screen; try removing the card, formatting it, or replacing it with a new one. Software crashes require a device restart to resolve. A blown fuse is a common issue—locate the vehicle's fuse box to inspect. The repair methods are straightforward: prioritize checking the power cable and fuse; if that doesn’t work, try the reset button. A malfunctioning dash cam while driving poses safety risks, so pull over immediately to restart or contact a repair service. Here’s a tip: opt for durable brand-name devices to reduce malfunctions, and don’t forget a voltage stabilizer when dealing with unstable power.
