My CCTV has worked perfectly up until Friday night, going back viewing playback it got "no video" displayed on all 4 camera's.
It still records and everything just no video , after searching on the internet I found a video stating capacitors which I've done but still same "no video " is displayed.
Anything else you guys can suggest?
Someone has said maybe not enough power?

Here's the inside below

Yes, were working fine,no one went near them they just went off , going get power supply checked
 
Camera psu faulty or one camera faulty pulling the psu down if it’s encapsulated psu with a splitter cable …
 
Format harddrive and now says normal, tried cameras 1 at a time, still no good
BNC cables
 
Thanks will try a PSU first, really appreciate your help.
 
It's power supply.
How do I know what jack size plug I need?
 
Got the PSU and then was getting this fault even after a format , now 30 minutes later I can now playback my recordings......which I wasn't able to do once I connected the new PSU...... bit strange?

It’s upsidedown ….what’s this got to do with the psu for your cameras ? …. Did you have a power surge that took out your camera psu and your hard drive ? Open cctv dvr and look at the capacitors in your dvr are they bulging?
