Apex TV using Toshiba code 0156... I am trying to duplicate the 'previous channel' command from the original remote onto a universal remote (URC-403...something... the model number worn off). The one built into the 0156 code does something different when I press the 'previous channel' button on the universal (displays CC status). I'm simply trying to get my OFA remote to go to previous channel on my Apex TV. Same code on the same remote works properly on my Toshiba TV.
