@gardening47fun you want to disconnect all video sources (including your Direct TV) the unplug the set. Hold the power button down for about 1 minute. then plug the TV back in and connect one video source. Preferable a local source like a DVD or BR player. Then turn it on and see if your picture stays on for longer than what it used to. If it does not and if it goes dark, darken the room and shine a flashlight beam at an angel against the screen. If you see shapes, silhouettes etc. you know it is your backlight that is out. This could be an issue with the backlight array as well as the power board. We would need to know the exact model for your TV and eventually you would have to remove the back from your TV. Then post some good pictures of the boards and interconnect cables with your QUESTION. It will allow us to see what you see. Adding images to an existing question
