How to reset dhr-5006 dvd player and how to connect it up to freeview and t?

How can I reset a dhr-5006 dvd recorder? I inadvertently hit a wrong button whilst trying to connect it to freeview and tv and now when I press set up, I get a screen on the tv which is half black and half white and the remote doesn't appear to work. I cannot get the set up options on the screen. Also, how do i connect it to a freeview box and a tv? I have tried to follow the instructions in the manual, but when I scan for channels there are none.
