So I got an 820-1521 in today - completely dead no sign of liquid anywhere. No damage visible - the machine is stuck at 5V on both ports. PPBUS is 12.31 PP3V3_G3H_RTC is present. PP5V_G3S and its associated enable is missing. Awake and Sleep voltages are also all missing. Not detected at all when I try to force DFU Mode. No visible shorts on any of the awake or sleep lines.
Still very new at these boards but i've run through everything on the wiki but cannot see anything directly pointing to my issue other than possible dead U7800? Am I thinking along the right lines? Is there any good source for U7800 or I just need to find dead boards?
