I need the AN7522 adaptation diagram on the Panasonic ct-f2125

Please I need the adaptation diagram of the integrated audio AN7522, by AN17807N, of the Panasonic TV model CT-F2125N, I have read on this page that they have solved this problem by adapting the AN7522 and the Ic TDA7056b

Thank you, for the contribution, but I have a doubt because it does not look good in the picture of the diagram, what is after the pin that comes out of the micro, nor its value and before the preset, the other is for not having at hand the MJ13007 which is a Switch transistor, to do the test, if it regulates the voltage used by the ic of the board to the new voltage needed for the AN7522N, the 13v voltage of the relay enters the base, in the collector goes the 24v voltage and by the emitter what comes out? I await your answer ....... I was not lost hahaha, I was working with this TV adapting the TDA7056B, and I did it.

I would really have to comment on omarramirez2014 because he got an accepted solution, but I answered, a 1k resistor comes out of the micro and goes to the volume control potentiometer. from the emitter of the transistor, the 12 volts that feed the an7522 are output.

Thank you friend Victor E, for the clarification, I hurried to qualify as accepted the answer, because I thought it could be seen enlarging the image and I did not succeed, of course I know it is 1k, as I do not have the diagram, only I will have to Search the chassis for the part number of that resistor, and if there is to place the preset directly at the entrance of the volume of the AN7522N or should it be replaced? I had seen in another forum that the jumper L2350 is replaced by a 3.3k resistor. Nor in the image is distinguished which are the models of TV. I don't know if the one I have comes out that 1k resistance.

Here I leave the link from where the colleague took the image of adaptation of the integrated sound.

I had seen that forum today, but it doesn't look good either
