Remote only controls TV volume - DirecTV

I can't get my remote to work with the tv beyond vlume control (i.e., I can't use the DirectTV remote to turn the tv on/off). I realize this is a 1st world problem, which means it isn't a problem, but if anyone has figured out how to fix this, help would be appreciated.
