You said satellite works but not cable.. There are a few configurations I will discuss, Pick one please:
Satellit is a roof mounted antenna (Dome or dish don't matter)
Satellite is ground mount connected by dedicated cable marked SATTELITE
Satelilte is ground mounted connected via the only external cable Connection.
Satellite cable runs in through partially opened window.
IF it is the next to the last (Only external cable connection) then that cable has been re-tasked, I do not recommend this, You will have to re-wire the cable. Winegard gives one bad idea, I have a better way.
Home is where I park it!
