Dahua 32ch DVR problem

Recommended Posts

Happy Memorial Day all.

 

I came across one of these units that continuously makes a clicking noise then shuts down after trying to boot (grid w/o video displays for a second or so, then unit shuts down). Clicks coming from the i/o panel at rear of device, not psu or drives.

 

Any ideas as to what caused failure? Can the i/o panel (which appears to be slotted into mainboard) be replaced at reasonable costs? TIA

Hi. On the 32 you should have a few green led lights on main board

 

Remove the lid and restart unit and see if they all come on

 

 

Also unplug any H/Drives connected.

Tx for the response. Did open unit and disco'd all drives and tested psu. There are some LEDs on mainboard that light up then go out on boot. Also found what I took to be a reset switch. I have no docs or schematics for the dvr, and am at a lost.

Not on site right now, but what am I looking for? From my time with the DVR, there was no change booting with or w/o drive connected.
