@deek72 could be a bad panel, bad power board/inverter or bad LED backlight array. It will depend on how dark it gets. Post some images of what you see with your question. Use [guide|21499|this guide] for that. Remove the back of your TV after you unplug it and take some pistures of the boards on the inside of your TV as well. Let us know what the model is.
