Good companions, I take guidance to face these 2 screens, both were inpactated by lightning, I have checked the source in the primary area, all the components are in good physical condition, in the capacitors of the source that are from 47uf to 450v I have 167vcd but I have doubt in the source transformer on the input pins are that voltage of 167v but when measuring with the multimeter the other end of the transformer I get no voltage, ahy a smd transistor next to the optocoupler fully busted on both cards I can not see the nomenclature To be able to replace it, now having this measure in the transformer to confirm with your experience will it be the transformer that is giving me the breakdown by not having voltage at its output will not need a feedback? will be the transformer
