You might try hooking the tv up to your home (or another) antenna or cable system to confirm the need to replace it. Other than turning it on/off several times thats about all you can do. Confirm also that your input is set for antenna, cable, or whatever your feed is. You might also try a media input to see if you get any kind of picture.
