Did you check PPBUS_AON and 3V8_AON in diode mode?

Remove both F5200/1 and check C5250 voltage.

Boardviewer | Program for viewing all types of Boardview files

 

[bartech]

there is little diffrenci in that boardview but i think c5250- 5,16v

 

[2informaticos]

Strange, you should have 12V, or 0V.
Check voltage directly on the fuse pads, once removed.

 

[bartech]

5,16v on c5250

You've said that you are not sure about it.
Why don't you check on the fuse pads?
