If your DVR / NVR system is not powering on after being moved, bumped, or dropped, it may be related to a power source issue or a loss of connection with your hard disk drive (HDD).
To verify that your system is receiving power:
If you have verified that your DVR / NVR is receiving power but will not power on, check your internal DVR / NVR connections to see if your HDD has become loose.
To check if HDD connections have come loose:
Power off the DVR / NVR system and unplug all cables.
WARNING: Ensure the system is powered off and the power cable is disconnected before opening your DVR / NVR.
Remove the screws of the DVR / NVR cover, then slide the cover off.
WARNING: The inner casing of the DVR / NVR has sharp edges that can lead to injury if not carefully handled. Be careful not to let any tools or loose parts touch sensitive components such as the circuit board.
Disconnect and reconnect the cables that are directly connected to the HDD to ensure that connections are secure.
Carefully replace the cover of the DVR / NVR and secure the screws.
Reconnect the power adapter and monitor.
Power on the DVR / NVR to see if the issue is resolved.
If you have followed the above steps and the DVR / NVR will not power on, contact Technical Support.
