Could be corrosion anywhere. Check the usual suspects, U1900, U1950, J6100, U6100 and termination resistors/traces.

where does PP5V_S4RS3 come from and what can i do to create it? i checked all 4 locations only thing i noticed out of place was r6117 was disconnected, from both sides. replaced and retraced, and i have 3.3v running threw it now, but still no change. sucky part is that it was working, once i ran the line. it powered, now something somewhere else went out and i feel it may be internal.
