I did check the cables and I even tried using another old mini cable box that works. There is a splitter but I think it can't be removed because it goes to another room with another TV and minibox (that also doesn't work). Is there anyway to get a cable tech to come out and check the coax cables to make sure there's nothing wrong with them or the splitter?
The only 2 inoperable Mini Boxes in your house are on the same coaxial splitter?
To tell the truth I'm not sure, I don't know the coax cabling schema for the house. I tried swapping the miniboxes between both old CRT TV's and they both failed to connect although the older one doesn't report the error message the newer one does.
