Dead circuit board ( fixed)

[Thestaar]

Hello, I need some help.

Have a Timberline 850 not d2 version but wifi. I was trying to diagnose a non working fan, (fan replaced) and accidentally shorting out L and N on the step down converter, and now the board is dead, i replaced the fuse but no voltage at the fuse, I have voltage on mains input.

does someone have a circuit board diagram or something that can help me.
thanks in advance.

I found the problem, broken trace in the board from mains input to fuse. I soldered a jumper.
