The TV goes automatically off because the main chip detect an internal problem, **** as a burnt capacitor or resistance, a defective IC, a wrong voltage or a short. In this situation the TV activates a safety switch that turns TV off to prevent further damage.
Try first unplugging the power cable for thirty minutes this will drain power completely and reset TV eeproms.
If this does not work it means that there is an internal problem, components on tv pcb boards must be tested following troubleshooting diagrams to fix the problem.
