Missing P3V3S5, P3V3S5_EN_L (0V) no short to ground

What is wrong there?
Did you note ending "_L" (meaning active low)???

Post U7200 basic voltages; pins 16, 13, 3, 8, 17, 6.
 
Yes. Active Low. You're right

Voltages for U7200:
16 - 12.59V
13 - 3.42V
3 - 2.00V
8 - 3.32V
17 - 5.02V
6 - 0.79V

Thanks in advance
