Why wont my tv turn on. No power it just turned off.

Chris, I most certainly agree with Phillip Takahashi that we need more details to really help you out. Hope you are handy with TV repair, since this model seems to have its issues. Do a search on here and see if some of the old answers will help you getting started. Click on solutions and scroll through those. In the meantime, I attached the No Power flowchart for you so that you can see if it is one of those errors. I do have a feeling that you are looking at issues with the power board. Commonly the capacitors on this board go on the fritz :-) Of course make sure that all the fuses are okay and that you have nothing visible shortening out the board. You can download the Service Manual from here Hope this helps, good luck.
