        should cover it, refer to the link to the firmware install for bossa procedure after going through the link above.

            Have you disconnected all other wiring?
            Have you removed the SD card?
            What LEDs are lit when connected to VIN?
            Which are lit when connected to USB?
            Have you used the erase button yet?
            Have you tested the blade fuses with a multimeter?
            Close up, well lit, photos of the board might show a bad component.

              I disconnected everything try to erase and reset and the lights that you see in the picture are still connected if I hook it up to 24 volt still same if I hook it up to five volt via PC still same the X and Y stop LEDs and the 3 and 5 volt I tried looking over the board for any damage I could not physically see any

                Did you go through that link and place the erase jumper to wipe any firmware? That should get it to show up as a Bossa port on the PC for reprogramming the firmware.

                Did you test the blade fuses?

                Did a racoon chew on your plug headers?

                    Do you notice any components getting hot to the touch?

                        Is this a new Duet? Did it ever work?
                        When and where did you purchase it?

                            Can you post some photos of the top of the board so we can see if there's anything blown? Try get a close up well lit steady shot.

                                  Why are the tabs on the connectors broken?

                                    @Phaedrux WHEN I WAS SETTING MOTOR ETC IT WAS EASIER FOR ME TO TURN AROUND CONNECTORS THEN SWITCHING WIRES SO I CAN GET TO HOME IN CORRECT DIRECTION

                                      There seems to be some burn marks near the fan header?

                                          I am trying to work out what could have gone wrong with this board. Few questions:

                                          why is there burns here:
                                          6d4042f5-899e-450c-a18c-c61c51c58ca6-image.png

                                          Why is the housing removed form the fan voltage select header:
                                          f5d9811b-58ea-4425-b7b9-5b2a8ac6ce03-image.png

                                          You say that the ESP and card reader get hot. That indicates they have been damaged, does the ESP still get hot without the SD card in? This damage normally happens when VIN voltage is applied to the 3.3V signal lines.

                                            @T3P3Tony the housing was removed by accident came up with the jumper when II had 24 v hotend fan and switched to 12 v I used a a step down buck with positive connected as per douziki come to think of why the burn marks I did a hot shrink repair but board was off and used a hot air gun pretty positive that had no effect do you think because that housing was off that the vin power touched ocb and caused short?

                                                @KevinSant what can it touch the 5v pin ? and why would that make those lights freeze? so now what throw it in trash and get another or would it be cheaper to get repaired being less than a month old

                                                  Given the damage to the board the best we can do is offer a reduced cost refurbished unit on exchange. If that's of interest to you, please contact roland@duet3d.com to inquire about availability. Please include a link to this thread.
