I present a description of the conversion of the Philips LED TV power supply on the PF6005AS integrated circuit to the NCP1207 integrated circuit, which is more available. The "pinology" of the NCP1207 except for the two pins is the same as the PF6005AS.
Pin No. 8 of the NCP1207 chip is connected only through the 10k? resistor to the plus of the main capacitor of the power supply (cut off other connections that were on the board).
Pin No. 1 of the chip (PF6005AS) NCP1207 is cut off from other connections and connected through a 10k? resistor and through a 220pF capacitor (in parallel) to ground and through a resistor
39k? to the end of the transformer winding from which it is supplied after straightening the pin no. 6 of PF6005AS / NCP1207 Chip.
