Tv keeps shutting off

@esbritt82 before taking any guesses here we need to know the model of your TV. than you need to let us know if it turns all the way off, like a power disconnect or if it just turns dark. Let us know if there is any sign of life when it turns off. You will also need to let us know if you have to wait to turn it back on or if you can turn it back on right away. IF you can, then it is most likely not a capacitor issue. It will most likely be a power board issue but to make that determination you will have to give us the information requested. You do need to take the back cover off and take a look at all the boards. Look but don't touch. Post some pictures of all of your boards and post those with your question. Use this guide for that. It will allow us to see what you see.
