I have a hitachi 32cx10b 32" TV from 1996-97. It suddenly lost a bunch of menu functions as if it thinks it's a lesser model TV. The S-video and video 3 inputs disapeared of the menus. Along with other functions like the selection to turn the internal speakers on and off. Help!! My Home theater is all wired S-video and now I can't use that input. Any information would be great!
