My On Demand has been out for about five days, since this past weekend. Chatted with a tech on line, she sent a signal to the Cable box, nothing changed except now a lightning-shaped light on the front of my cable box is constantly flashing. I tried unpluging the cable box for varying amounts of time, but that didn't work either. The outside cable box is located outside of my window. Birds are nesting in the outside box constantly because, for some reason, the box is always left open. Could the birds have pecked at the wires, and caused the problem with my On Demand recepton?
