Smart TV Toshiva mod.58L4300U has audio and video, they do not illuminate the lamps, they only flash and sometimes turn on for a few minutes ... power supply to the inverter it drops to about 120 volts for L + and for L- 0 volts, when the lamps work L + 144 volts and L- 37 volts .... this circuit between its associated components has two Capacitors of 22mf 250 volts (They have already been changed) and a Mosfet FQPF9N25C which I need to exchange but I don't have it, I've been looking for it in the few pages I know to order it and the only ones I find are too late to arrive. If someone can guide me both in the defect and in the component I will be very grateful. Thanks repeatedly. photostudio_1513372376467.png [188.97kb] I have
