you could run a new cable from the working one to the bed room, useing a splitter, but i dont know your set up, but then you will have a problem with the new cable run, hidding it, can you follow the none working tv point back to the other end and see the problem, i would try use a tv splitter from the working one and drill through the wall, and put a new tv box on the bedroom wall, if the distance is short,
