Power light comes on then shuts off

Why wont my vizio tv stay on? What is wrong with it?

ANSWERS:

johncruver973  could be as simple as a bad power board. You need to let us know what model this is, what you have checked and give as much detail as possible. I would start by checking the power board. Once you remove the back of the TV, post some pictures of all of your boards etc. with your question so that we can see what you see. Use this guide Adding images to an existing question for that.
