A:Answer The TV button can be programmed to select the input you wish to go to. If you go into SETTINGS and select INPUT DEVICES, one of the menu options will be to program the TV button. When you select that it will give you a list of inputs, just select the input port you want to associate with the TV button.
I have my satellite receiver feeding to HDMI 1. I have programmed my TV button to select HDMI 1 so everytime I press it, it opens my DirecTV service.
