TV won't show picture or sound.

My TV screen only shows  about 3 channel listings at the bottom of the screen.   But when I try to click on one of them, the screen goes black.  No sound or picture.  I looked in the book and it seems like a parental control is set on my TV.  I haven't put parental control on it though.  Any suggestions of what is happening?
