Nintendo DOCK is not working

I have a problem with Nintendo’s DOCK.
Dock is not working. The only thing I found was a short circuit to GDN on pin 12, marked in green.
The other test pins are set to the correct values.
What could be the reason why this short circuit occurs?

remove M92T55 and check if short gone on the pin12

Where can I find the values for the test points? Thanks!

Tkanka, the short circuit is gone. I have to replace this element.
