Good morning friends of the forum I am trying to solve a flaw that this TV of the Siragon Model TV-5100 brand presents since it is HEARED AND THE PICTURE IS NOT SEEN I went to review it and I find present the voltages of the source 12v-24v and 5v then I uncover the screen and I find inside the TV the Inverter Card and the 24 vol coming from the source is coming from the source how curious that at the exit of that card where the lamp cables are connected there is no voltage present and other forums are seen by this means that about 150 volts should be present in that connector to power the LED strips after all, I go to measure the components of that card and I find the Surface Mount Mosfet Transistors with the numbering SM1F02NSU suspicious and I would like to replace them but I can't get them Now with your experiences you could tell me by which other mosfet so normal that is not smd would replace it

Good morning, there is no voltage because the inverter must be protecting from LED strips, check the LED strips, or led by LED if possible, there should be burned LEDs, said voltage appears at the time of ignition, but as there are diode problems Bad LEDs this voltage disappears.

I told you that the TV disconnected the strips and I tried a 24 Volt homemade tester and they turned it on, I did it strip by strips but two of them did not do it but when reconnecting it and trying again they turned on what I had was false contacts in The connections of the strips what I did was to bridge to avoid that false contact later everything was ok and of course the voltage of the Inverte appeared with 146 vol Dc Thanks to Victor E and oswaldo lizarra for these data that were also very helpful
