Welcome to Android Central! I translated your question using Google Translate, since it's mostly English on this forum:
"Good Morning. Anyone can explain me how can I watch live TV on the tablet, is that I already try to install the Flash Player, but it does not. Thank you."
Live TV would require a website or app that provides a live stream, assuming you're not trying to connect your tablet with some other device, like a Slingbox. Are you trying to access a certain website that has live streaming TV?
