PPBUS voltage? Q7055 shorted?

 

[rzeszu]

PPBUS 11,57V
Q7055 if I understood correctly "shorted". Yes, it is shorted
PIN 4 - 4,5V
PIN 5 - 11,57V
PIN 1,2,3 - 11,57V

OK, I think problem solved
I change Q7030 because voltage on PPBUS on adapter was too high.
If i find another problem on this board I will write it later.
