The dashcam screen is black? | AZDOME dash cam App

Fix a black screen on an AZDOME dash cam — check the power cable, reset accessories, and verify hardwire wiring.

Please confirm whether the power cable is the standard power cable for this model (some models may not display if the power supply is insufficient). If it is not the standard cable, please replace it with the standard power cable and check again.
If the dashcam makes a startup sound but the screen does not light up after powering on, please try turn off the device, remove the memory card, and unplug the cabin or rear camera. Then power on the device and press the reset R hole (Reset) briefly or long until the device responds.
If a hardwire kit is connected, verify that the wiring is correct. Please connect the red wire to always powered, the yellow wire to ACC, and the black wire to ground.
