Black Screen, Tv Does Have Sound

Model Number for Samsung Tv Is : UN60J6200AF Pretty much what’s going on is, The Screen is Completely Black, Sound is Coming out. I Turned all the lights off in my Place, Took a flash light, Did the Flash Light test. I hit settings i can See The Settings and everything on there, I did try and turn up the Backlight Settings, And Brightness Nothing happened. Watching Videos they said lay in On its face, I did and they said you’d Be able to see the back lights were on, I did not see any back lights. Now from the Research i have done, People are saying its More then likely the Back Light Inverter, I cannot find the back light Inverer, Any Advice would Help. Thank you!
