Victor thank you very much for your help, following your advice I found a Schottky diode model STPS10LCD100C in poor condition, well look in my city but I did not find it, the closest thing was a 20100CT, I soldered it in replacement and the TV started perfectly, my Question is if it is suitable to leave it definitely, thank you very much greetings!
