If 2 hours, 28 minutes and 38 seconds is all the patience you have, then doing component level troubleshooting on a DS4 board is really not going to be your cup of tea.

There are no fuses on the board.

What chip have you been changing? Pics?

Does the controller work with a fully charged battery from another controller?

Does it work connected with the USB cable? or do anything at all when connected to a PC over USB?

Is the FPC cable from the motherboard to the microUSB/LED board good? It's very easy to ruin the contacts on those cables, even if they are only unplugged and reconnected 1 time.

Do you have a working JDM-040 to use for comparison?

hello I apologize for the rush.
I mounted a chip and flat a working 040 jds but nothing happens.
I also tried to connect a charged battery but nothing.
I also connected the joystik to the PC but does not see the led remains off as if it were not powered.
I have repaired many joystiks but with regard to this flaw I have not been able to understand the damage
I think it's a factory defect since I've had 4 motherboards with the same problem

Chip of carge (guessing you meant charge) really tells me nothing, so I still have no idea what you have done to the controller.
