Jeff Hafely start off by checking for power to your TV. Check the outlet and the cable. After that remove the back of your set and check the power going to the power supply, then the fuses on the power board. Check those for power as well as continuity. You will need a multimeter for further testing.Post some images of all of your boards with your question so that we can see what you see and guide you through some more tests.
