Check and see if a circuit breaker is in the back of your tv. If there is one press on it as if you were ringing a doorbell. If the tv comes on great. If you hear the circuit breaker "click" and you still have nothing, there is a short in your set. Take it to a repair station. If there is no circuit breaker you probably have a blown fuse in the power supply. Take it to a repair shop.
