Click the power-off button on the dash cam and then turn it back on. If there is no response, you can directly cut off the power and restart it. To save power and avoid glare, the dash cam has a screensaver function that activates automatically. Simply turn it off. Press the buttons on the dash cam to see if there is any response. If it freezes, cut off the power, remove the SD card, and reinsert it. If none of the above steps work, it is highly likely that the dash cam is damaged, and you should replace it with a new one.

I've had a dash cam for several years, and when the screen suddenly went black, I immediately checked if the power connection to the cigarette lighter or USB was loose. If it's securely plugged in and still not working, it might be a blown fuse—check the manual to replace it. Next, take out the SD card and try formatting it on a computer to see if it's full or corrupted. Restarting the device can sometimes resolve temporary glitches. For hardware issues like a broken screen, you’ll need to visit a professional repair shop. I regularly back up video files to ensure evidence in case of an accident, and I recommend clearing the SD card space monthly. A malfunctioning dash cam is dangerous on the highway, so it’s good practice to confirm it’s working properly before every drive.

As a car gadget enthusiast, I've encountered dash cam black screens multiple times. Start with simple steps: press the power button to restart and check response; inspect if the charging cable is damaged or the port is loose, try another cable; enter settings menu to confirm power-saving mode isn't turning off the screen. SD card issues are common - backup data then format or replace the card. Firmware updates can fix software bugs - download and install from the official website. If truly unfixable, consider buying a new device with Wi-Fi function for convenient remote video viewing and peace of mind.

When the dash cam doesn't light up, I usually first check if the charging cable is properly plugged in as it might have come loose. Then I remove the SD card, blow off any dust, and reinsert it to see if there's poor contact. If the screen remains black, try restarting it or pressing the menu button to adjust brightness. Last time mine wasn't working because the card was faulty - replacing it with a new one made it display immediately. If all else fails, search online for the model number to find troubleshooting guides or read the instruction manual step by step. Driving without recording isn't safe, and getting a new one is quite convenient without spending too much money.

I have dealt with numerous dash cam malfunctions and usually diagnose them step by step: first, test whether the power supply voltage is normal by measuring the output with a multimeter; clean the SD card slot as foreign objects may cause poor contact. For screen issues, disassembly is required for inspection, but it's easy to damage other components—DIY is not recommended, seek professional repair. Device aging is a common cause; back up important videos before sending it for repair. For prevention, conduct regular checks to avoid water ingress and short circuits during rainy days. Dash cams are crucial for evidence preservation—safety first, don't overlook it.
