How bad is this analog board? Mac SE/30

Howdy everyone,

I recently picked up a Mac SE/30 locally in my town, and when turning it on, I get a 1" inch wide screen running from top to bottom. I ordered new cap kits for the motherboard, PSU, and analog board. But I'm worried the analog board might be toast; there's lots of black residue all over the board and inside the Mac.

The analog board looks like it may be ok, but that flyback transformer looks like it has a lot of soot on it, which means it was well used.

Is that a crack where the arrow is pointing, is that completely separated?

EDIT: Page 161 in the Dead Mac Scrolls describes the vertical line condition you're seeing. How are the solder joints for the yoke board connector?
