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).

unfortunately, I applied 12V instead of 5V on the DC jack.
Now, only 1 of 2 diodes is lightning up.
I am looking at:
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!
