Program XR15 Remote for Phillips TV.

I just traded in my old equipment for a new set top box. I have been unable to program the remote to turn my TV on and off. 

The TV is a Phillips which is recognized by the setup for the XR15 and the volume control works but the power off doesn't. I can't figure out how to test it or enter an alternate code to see if I can get it to work, although I just founs a description of it online. 'll try that after the game.

Also when I had the volume working with the buttons I tried the voice control and it told me it couldn't yet do that. Does that mean that function is currently programmed or that it nor currently possible?
