@dsmitty29 let us know what exact model this is. It is possible that this is caused by a bad power board which then causes your backlight to turn off, but can also be a T-con or main board issue. Let us know if only your picture turns off or if you lose sound as well and if the picture comes back on. You do want to try to reset your TV. Unplug it and push and hold the power button for about 30sec-1min then plug it in while holding the power button depressed. If that does not help, remove the back of your set and post some good images of your boards with your question. That way we can see what you see and could try to assist you further. Use this guide [guide|21499] for that

@dsmitty29 "you can see the picture like that. " is indicative of a bad power board. The power board supplies the voltages needed by the backlight. Of course there is a possibility that your backlight LED array has failed or you have some loose cable. You have to check this out by removing the back and measuring the output of the power board. If the power is supplied but the backlight turns offoff, it's the array.
