Have got new dm 8000 hd pvr and when everything connected ( power,lnb, scart and ethernet cables) blue light on front comes on but thats it nothing else happens even trying hold the up channel power and switching the power on does not work. The front screen does not even display anything nor do i get anything on my tv and no ip address. The person i bought it from said it needs software installing. Can someone please advise on what i should do?
