This is the for sale section, I suspect that you will not get much help on a troubleshooting question here. There's noting on that board that you can easily repair if it's fried ....

so now through the magic of "ghost in the machine" the thread is in the proper area.

Both of the ground pins need to be returned to ground for the board to work correctly.
