Dash Cam Won’t Turn On: Common Causes
A camera that will not power on is usually a power-delivery problem rather than a dead camera. Check the simple things before assuming the worst.
Check the power path
Inspect the cable, adapter, and connection for damage or looseness. Try a different cable or socket to rule out a faulty accessory.
Check the fuse
On a hardwired install, a blown fuse cuts power entirely. Confirm the fuse on the camera’s circuit is intact and the ground connection is solid.
Reset and assess
Try the reset button and remove the SD card in case a corrupt card halts startup. If nothing works, the internal supercapacitor or battery may have failed.
If it is a wiring issue
On a hardwired camera, power problems often trace back to the install itself — see Connecting a Dash Cam to Your Car Battery Safely and Dash Cam Power Options.
Frequently asked questions
My dash cam turns on but will not record — is that the same problem?
No, that is usually a separate issue related to the SD card or settings rather than power — see [Dash Cam Not Recording?](/guides/dash-cam-not-recording) instead.
When should I stop troubleshooting and assume the camera is faulty?
If power, cable, fuse, and SD card checks all pass and it still will not turn on, an internal fault (such as a failed supercapacitor or battery) is likely, and it is time to contact the manufacturer.
