Thank you, colleague, if it is the same as my board, I am trying to lower the voltage to the LEDs, I understand that it is done in the negative return of the LED strips, I am a little confused, I have to lower it directly from the batch of resistors in parallel that come from leg 7 of ic u8601 or source of mosfet q8601? any ideas?
