I just hooked up a new HD DTA and everyting seems to work fine, i.e., powers on, changes channels, adjusts volume, etc. However, one problem is remote does not turn the cable box off when I select "all power".
OK on DTA. I can't turn off TV with comcast remote. Do I need to use TV remote, i.e., separate remote, to turn off TV?
Have you entered the proper code for your TV? Instructions can be found here:
