Good morning: Diagrams of this chassis series will not get. It is not uncommon for Chinese chassis. I think they are not important, if the TV turns on, it can be operated directly from the remote control; In any case, always the resistors located in the buttons have little commercial values.
Here I am again, I was googling around and I already have the R values I was looking for, I got them compared to the Chassis diagram 40-00NX56-MAN1XG NX56LA, I share them here for all of you:
R1001 = 270
R1002 = 330
R1003 = 470
R1004 = 560
R1005 = 1K
Thank you very much to all who wanted to help me, regards ...
