'''++melanie-hirst11++'''  that could have many causes. Try narrowing it down by placing the TV on a station that is broadcasting (you will have sound) then darken the room. Shine a flashlight at an angle against the screen. If you can make out silhouettes etc. you know that it is the backlight that is not working. Could be a power board issue. If you do not have that then it is most likely a main board or a T-con board issue. For that you would have to remove the back from your tV and take a close look at all the boards. Look for burned traces and obviously damaged components. If unsure, post some good pictures of everything with your question. That way we can see what you see. Use this guide Adding images to an existing question for that. Also, please verify that your TV is a LG 60LM6450
