Tried cleaning cables and reconnecting didn't work. When the cable box booted up there was a screen that said user settings black screen white writing, when the cable tech had me hit it in remote that is when color went away. Cannot get back to that screen. Also put a DVD in it played perfect with sound! So it is something in the tv settings!
