Hi guys,

Maybe someone can help me.
I have SDS100E to repair. Came to me with a diagnose of a ripped charging USB connector.
But after opening it, I've found that one of the IC is burned and marking is not recognizable.

It's some of DC/DC converter.
Found the short to the ground on test point marked as "+2.5V" after removing IC short is gone.
Tried to replace with external DC/DC from 5v to 2.5v - but with no success for now.

Thanks in advance for any suggestions
