RB951Ui-2HnD "whoopsie"

Due to some water spillage I’m pretty sure i killed my power regulator circuit. I’m in desperate need for information about specs for the diode labeled D1, because it is running hot. Also, the output of the Chip nearby “LSC LSP5523” is plain gibberish and the output of its neighbor, LSP5526 is just not existent. So I guess FB1 burned out, preventing any reasonable harm to the real guts.
spare LSP5523’s are already ordered. Does anybody have any information about the diode i’m hoping to replace? There Is G6 - or C6 - printed onto it and I have absolutely no clue what the labeling is trying to tell me :frowning:
