Great job digging in and finding a solution. Especially since the part is no longer available. How annoying that little piece of weak solder can break a camera that cost hundreds.
I think I'm seeing the same thing. Opening a cr2 file in DPP or Imagebrowser does not show the outer edges of the picture. Same with Apple Photos. Opening in Aftershot or Luminar I see more of the picture on the left, right, top and bottom.
