Due to an unfortuante jab with the head of a screwdriver it looks like I
have at least one, possibly two broken traces on this GPU card, on the
traces running between the processor and VRAM. Result is corrupted
display output/won't switch into high-resolution modes. The ram is BGA
and the GPU likewise and under a small heat-sink so hard to test
continuity, plus the trace width is very small, looks like perhaps 4 mil:

Any suggestions for mending a break on a trace like this?

Assuming only light currents. Lightly abraid in that area , to enough
bare traces, cover with silver-loaded paint. When perfectly dry, score
parallel lines with a scalpel blade . Check for any bridging before
perhaps coating with lacquer
