New setup, BOLT and Charter Cable. Received the cable card and tuning adapter, hooked up as instructed. Bottom line, could not get about 40 random channels at all. Tried the usual resets, etc. Charter finally sends guy to look at it. First thing he does is swap out cable card, still getting same issue. Then he swaps out USB cable, still getting same issue. Then he adds a cable splitter to line coming in from street to feed the BOLT and the tuning adapter separately. Still getting same issue. He makes several phone calls to bosses and one of his other service people, stumped. So I suggest (like I did when he first walked in) to swap out the tuning adapter. He does, problem solved!
