This is about an insignia TV and a Shaw 2020B0-B1 remote and an aging relative who just got a DVD player..
The Shaw installer chose TV the code. The remote seems to control the TV as needed with one exception - the INPUT button has no effect, so there is no way to get the TV to display the output of the DVD player (to switch from (HDMI 1 to HDMI 2). The user would be confused by the need to use two remotes, so I need to get the INPUT button working.
I am going to try resetting the TV code, but let's assume the installer chose the correct code and that none of TV codes I try fix this problem. Is there a way to customize the signal sent by the INPUT button? For example can I get the remote to listen to the TV remote to learn that signal and assign it to that or any other button that would make sense? (I taught my remote a custom signal this way, but it is a different model).
