I am at my wits end. I cannot get a picture on my screen no matter what i try. I've tried to bypass my b-tech 945 and inserted the vga cable from my pj directly to my dvd player (should i get a picture then?) i got nowhere. My vga cable has 13 pins the receiving female locators have 15 holes (is this right?) Can i have purchased a faulty h30a or vdc-vga cable? Does anyone know the settings for the h30a connected through the bt945? Or, how i check that the cable and projector are working properly?
