I have 9 old BNC analog cameras that I had connected to a Dahua XV$, but it suddenly went black. Neither the HDMI or VGA output have any signal.
Does Dahua still make XVRs or any other brand to connect, display, and record 9 BNC cameras?

The DVR takes a 12V 2amp power supply which is for powering up the recorder itself and the hard drive inside. The cameras should have their own 12v power supply. Since your DVR is not having any video out I would first measure the voltage of the power supply going to the DVR. It should be a brick style unit. Check for 12 volts plus or minus .25 volts. If that is good then take off the cover which should be held on with phillips screws. Unplug the power to the hard drive and see if you are able to power up the recorder without hard drive attached. If it is and you are getting video then you will need to change out the power supply as it is not able to support the load with both the recorder and the hard drive. It's a pretty common issue. Can also grab a random 12 volt power supply to power up the DVR. I have used as low as a 12 volt 1 amp power supply to boot up the DVR without hard drive attached with no issues. Just make sure power supply is center positive on the 5521 barrel connector which most usually are.
Ye olde 5521 Center +.
So there is a name for that style Barrel connector.
Learned something new and it's not even 9 AM!
I'm currently running an Amcrest XVR.
