On my remote, 40.0. It will not allow me to program the TV button to control the TV. I have to use the AUX button instead. When I press the TV button, it just flashes and then goes back to the DISH button. The button is programed to control the TV in the dish menu and I have tried several different codes, all of which, work on the AUX button. Am I doing something wrong or is it the remote?
