I just examined the back of my Television Monitor: I have a xantech 789-44 connecting block which has its gnd status and IR conntected to screws on back of my sony. Connected to that is a 480-00 dinky link. I am beginning to realize that my original set up prevented power-toggling with the cable box but my new cable box and my old pronto are configured differently. My goal is to make sure that when I push cable on my pronto that it does not turn tv off only on.
