I currently have the NTL (Digital TV) service through a Pace DI4001N STB. I am trying to connect this to my Panasonic TH42PW4B plasma screen through the Keene SCART to VGA converter. I need to verify that the output on the STB's SCART socket is set to RGB, as this is the only way it will work. Does anyone know the method of accessing the service menu on the STB? I saw the engineers access it when they installed the unit, but didn't see the way they did it. Any help appreciated.
