@fsi connect via USB and go through this page too https://duet3d.dozuki.com/Wiki/What_to_do_if_your_Duet_won't_respond

@Argo did as you suggested, but fuse seems conductive
-
@droftarts big thanks, most leds lights up. Although can't find board in Device Manager, I'll try changing cable.
-
@droftarts did as you said, the board seems working over usb - answer on M115 was "FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.01(RTOS) ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2018-07-26b2<LF>ok<LF>"
What should I do next? Update firmware?

@fsi post picture of board, probably 5V or 3.3V regulator has blown. Best not to update firmware while troubleshooting.

@droftarts ok, it's bit dusty but hopefully you will see something
-
@fsi U2 (3.3v regulator) and U3 (5V regulator) look okay (they are to the left of the processor in your picture). I can’t see anything obviously blown, except I looks like there’s a bright copper wire on the corner of the SD card holder across to the WiFi chip?
Next will be to turn on VIN and use multimeter to check for 5V and 3.3V on expansion header.
Was the spark you created near the green heater screw terminals, or green VIN screw terminals?

@droftarts very gratefull for your help, spark was near heater blocks. What do you mean by checking voltage on expansion header?
-
He means to use a multimeter to check the 3.3v and 5v pins on the expansion header to see if they are getting power.
See the pinout for the expansion header here:
