Wire jumpers, some epoxy, and some silicone can even fix a physically
broken board in a pinch.

In the past, I've repaired even charred boards. Most of the materials pc
boards are made from carbonize and become conductive when exposed to
intense heat. I've used a dremel tool to cut/grind away carbonized areas
of boards and replace it with new material or wire jumpers. This is a
common problem in certain monitors due to a bad design of how the flyback
is mounted.
