I have the Sony Internet TV 46" and I'm trying to get the IR Blaster to see my Dish Network box and learn the codes so I can just use the Sony remote. When I hook it up, nothing happens. I page through code after code in the set up menu and it doesn't work. Then it asks me to enter my zip code and I get an error message and can't go on. So I'm stuck using two remotes - the Sony and the Dish Network. There is very little documentation with the TV. Anyone shed some light? Thanks.
