UPDATE:
Signal restored, DM functioning TV on.
Having found and repaired a corroded connector on the DM unit on top of the coach, I decided to check the connections on the LNB.
Well, there is a coaxial cable coming through the roof of the coach which is too short to do anything,so there was a coaxial connector and 2 feet of coaxial added on to reach the LNB. The pin in the coaxial was corroded. After replacing the connector,short added on cable and cleaning the pin, I tightened then applied a little heat shrink to the piece.
Inside I went and I received 90 and above signal strength on the meters and the Tv came on.
