This is all part of the process of elimination, especially if there were multiple problems, as what you had. The good news is that we might be getting down to the board itself, where things are clearly layed out and understood.

Indeed, it can get tiresome like this.

@Avance Concrete Fan can you give us a photo from below the board as well? More detailed/sharp the better.
