If I remember correctly, (from back in the early days, when this was a more common event):
The schematic page 22 is of more value. I believe when 12vts is applied, the chip U35 was the first (and usually only) part to go south. Though there should be some discussion of this in earlier threads (about 2 + years ago).

Now, only 1 of 2 diodes is lightning up. I am looking at: http://wiki.minnowboard.org/images/b/bd/Minnowboard_Turbot_X205_Sch.pdf p. 29: 5 V DC --> NMOS and Switching supply . Not sure where to look for the broken IC from this. What could I do to repair the board? Thanks a lot! Patrick
