Did you not think to include the model number of your TV, it's kinda helpful to do that.
Only thing that I can think of is you have activated the Screen Reader function.
Press Setting on your remote control and click on Settings on screen.
Scroll down to System, click right for Accessibility and right again.
Scroll down to Screen Reader and check to see if that has been enabled.
The path above is for my TV, yours maybe a different Sony model which has a slightly different path so use the above as a guide not an absolute.
