when i used to press "Internet Radio" the screen would display so i could select radio stations or network places, i thought. now it goes directly to cbl/sat/roku screen on the LG TV. Source at bottom of screen shows it is Heos.  i don't have wifi setup at home so the Heos phone app isn't going to work.  so i don't care about Heos.  
suggestions for getting Internet Radio screen to display when i press its button versus Heos as being source?
