Volume and menu does not display. I am having a strange problem with my TV. When I turn the volume

Question

I am having a strange problem with my TV. When I turn the volume up or down, the display that shows the volume increasing or decreasing does not display. The volume is increasing and decreasing, the display is just not showing. Also, when I choose Menu the menu screen does not show up either. Finally, when I choose Input, my input screen does not show up even though the input is changing when I hit the button.
