I used to have to press the STB and TV power buttons separately to turn on and off the TV's and set top boxes and now just pressing the STB button turns on both. If someone goes to turn them off and hits the TV power first and then the STB, the TV turns back on. Gets confusing when they get out of synch. Are there any settings on the remote or TV that would reset this to the way it used to work, pressing each one seperately?
