Does the surface boot, other than the touch screen? If so, have you tried the DL5000SystemManager program to see what it can do for you. I personally have not used it with an active surface, but my thinking was that it was supposed to be able to “replace” a non-functioning touchscreen and allow surface operation…. not sure about show file access, not 100% sure where they are stored. Some of the show functions were moved to the mix racks with 1.9 firmware, but that may only be the scene names.
