Avtech KPD674 Powering Off - Error 3-000

[miyagi 0]

Hi Guys

 

I recently bought an Avtech KPD674 DVR.

 

I seem to have got the hang of it, although about 4 weeks ago it kept powering down and reseting about once every 2.5 mins.

 

I took it back to where I bought it from and they apparently sent it back to the manufacturer who tested it for over a week and found no problems?

 

I got it back just over a week ago and it started doing the same thing....does anyone know what the problem might be please?
