Opening up the Jornada as far as it can physically go shouldn't damage the display cable unless the cable is improperly installed, or unless it's not seated properly in its connections on both ends. It sounds like the cable is not properly seated in its connection to the motherboard. This is not hard to fix, though - you just have to remove the bottom cover and reseat the cable. See this page for a video on how to disassemble the Jornada:
