Hello! I'm new to all of this eurovox stuff and to be 100% honest I don't really get it!!!

I inherited my dads old eurovox... its a max v. He was using it fine and then got sky sp its been sat in the cupboard for maybe 3-4months so I reflashed it but it's still not finding any channels so I was just wondering what I need to do?

Thanks a lot
