Doesn't start | Burned due to lightning discharge | It was necessary to replace the power supply board because it burned components that could not be recognized. Even after the replace, the TV did not turn on, analyzed the main board and found heating in the IC MP1482DS in position U1, on pin 1 voltage input of 5V and 3.3V did not come out on pin 3, replaced with another scrap and everything ok | Claudio Jorge Eckert Junior |
