Maganavox TV Troubles. My Maganavox TV has been workign fine ever since I purchansed it a little

Question

My Maganavox TV has been workign fine ever since I purchansed it a little over 2 years ago. This morning when I woke up, the tv would have sound but no picture. It won't even show the basic tv menus. It is just a black screen with sound. I believe that because I can't even pull up the basic tv menus, that this means that this is not a connection problem. Please help me with the situation as I have no idea what is wrong. Thank you.
