2879 Milk damage

[Tony Tone]

I found a short on PP1V05_SO, I pulled L7620 and seen it was on pin 2. So I tried some caps above it and pulled U7600. Short still there. So I injected 1.5V into C7660 and see that U1400 gets hot first when freeze sprayed.
I can assume u1400 is bad, correct?
I did a USC at different angles also already.

What do you consider a short? Resistance to GND?
