I have the Mitsubishi WD-73C9(73 inch 3D-Ready) HDTV. I bought the 3D Starter Pack(Mitsubishi 3DC-1000 3D HDTV Starter Pack), and one of the pairs of glasses is broken. how do i go about getting new glasses? how many can i buy? i would like to get 3 more so i have a total of 4. does anyone know which ones will work with my setup? ive been searching and searching but cant find an answer.
