shorted charge dock 12 pro max

[KBTZK]

Several devices of the iPhone 12 PRO MAX model with a reset defect arrived at my assistance due to the dock being shorted. I would like to inform myself with you if there is a possibility of repairing this charging dock, and if someone has already had defects of this type who managed to repair the dock.
It has no oxidation and the charging system seems OK.

If you have recently bought them can't you take them back?
Perhaps there's a problem with the translation.
