Lg voyager internal screen problems?

All of a sudden my internal screen on my lg voyager stoped working i figured out it turns on agin if i squeeze or start (not bending but puttng pressure) on the phone but if i let go the screen turns back off. sometime i can do it right so it will stay on for awhile but its almost as if a wire is out and if i squeeze it if goes back in? anwone know whats wrong?
