Hi all. I have a Lorex LHV2000 8 camera system which seems to have developed a fault. It started when I noticed no cameras were showing on the monitor and each window said 'No Disk'. Also, the fan in the DVR wasn't running. I rebooted the DVR which started up, fan running. When the camera 'windows' came up on the monitor, they were blank again and the fan stopped running. I did a bit of research and there appeared to be 2 possible causes, either a hard drive failure or the power adapter needed replacing. I had another power adapter the correct voltage and amperage to try which I did, and everything seemed to work fine, I could play back previous recordings without issue so assumed the hard drive was ok. I shutdown the DVR so I could tidy up the cables and I reconnected the power adapter to the DVR and started it up. Now, it only gets as far as the welcome screen which stays like that for a couple of minutes, reboots and continues this cycle. So I'm not sure what's going on now and wondered if anyone has had a similar issue. I've been on the Lorex support website, but there's nothing there covering my problem. Any help would be fantastic as I'm pretty stumped and I'm a bit reluctant to buy a new hard drive if that isn't the problem. I've checked the hard drive cable connection and it's good. Thank you.

The operating system on my Lorex DVR appears to be corrupt and won't get past the welcome screen on startup. Am I right in thinking that the OS is installed on the circuit board of the DVR and not the hard drive, and is it possible to re-install the OS/firmware from a USB stick?

No, unfortunately not. I didn't get anywhere with it, so I've just ordered a new DVR from ANNKE. It was only £54 with no hard drive as I'll be using the hard drive from my Lorex.

Thanks for the response! The power supply was the original problem. I noticed the fan wasn't running on the DVR, the camera previews were blank, and they all said no disk in the corner. After a bit of troubleshooting, I replaced the power supply and it all started working again. I had to shut it down again to re position the DVR and when I started it up, it got stuck on the welcome screen and it won't go any further. I can see a small led on the circuit board flashing away as if it's trying to do something, but after a few minutes, it just reboots and continues this cycle, so I'm stumped! There's no support on the Lorex website for the model I have either, so I can't get any help there.
