    I returned to weld all cables but still does not work. without the LED and the connected foc this works. I think there must be something wrong with the led, or connecting the LED nb

    He means, do you have solder crossing from one pad to another on the led?

    I tested with 4 different LEDs, it is unlikely to be led problem

    Your not understanding...look at picture below....the orange arrows i add to your pictures are pointing the possible spots of the bridged pads he was talking about. You can't have solder splatter or overflow on those pads. You need to keep the solder on those little circle or square pads.
    And the black wire on your LED could be your problem...(no offence but that one is a mess) ...you need to remove and clean the black wire on your LED and redo it.
    Also i know how it is being limited on different colored wire. Using the same color wire in 2 different places can confuse you and also possible damage your sound board by accident. Best to use different color wire for each point on your sound board.

    Now I have changed the positive LED. it was previously connected to the positive of the battery and now I put it in the positive pad of the nb and now works!!!!
