Hello friends, I have a question with the pin f / s of a flyback, I would like to know what its function is, it will be the same afc? is to adapt a flyback, I appreciate your answers. The nomenclature of that flyback is this 1 collector 2B + 3WIDTH 4 220V 5GND 6HEATER 7 25V 8 14.5V 9 F / S 10 ABL 11 GND

That is correct my friend is AFC. But if you doubt my word make the adaptation, the TV turns on without that pin. although the image will look sloppy. connecting said pin is solved. If you do not have a Flay that has said pin, you can try to connect it to the heater pin (It has worked in several cases), or make a return to the fly core with enameled wire. Regards.
