What you'll notice
No lights, endless boot loop, or the logo screen forever; cameras and monitor are fine.
Why it happens
A failed internal power supply (very common after surges and load-shedding spikes), corrupted firmware, or a shorted hard drive dragging the rail down.
How we fix it
We isolate PSU vs board vs drive, repair or replace the failed part, and re-flash firmware where recoverable — recovering your recording archive whenever the drive itself is healthy.
Still not working?
If the checks above haven't restored your dvr (digital video recorder), this usually needs a technician. Our DVR Repairs service covers exactly this fault.
