Update and summary opinion: Do not bother.
This problem exists at the intersection of fiddly, fragile, sensitive and lousy quality of the common repair parts. I do feel that a better repair kit could be successful.
Completed one connector and it worked, for a few minutes than started a flicker and pixelating. I remade the connections and the signal quality deteriorated. I then started again with the second one which went together well using what I learned from the first. Despite looking great, it would not pass any signals; only a few of the individual connectors had continuity. Frustrating and now I will get a new cable and an opportunity to do patch and paint.
That said, if anyone wants to try this w/ the Amazon kits here are a few thoughts;
1) strong reading glasses if you are of a certain vintage, 3.0+
2) the screwdrivers that all of the kits appear to include are a bit large. Carefully file them both on the taper as well as diameter or use a higher quality driver ideally with a spinning top.
3) the wires are very small, 26-32 ga and the very small terminal clamps that retain the wires in the repair kit have sharp edges which cut the wires if tightened too much. Unfortunately the difference between not enough and too much is minimal. Finished edges on the clamps would be ideal, my point on quality,
4) packing all of the wires into the included cases would be a challenge if you get that far and too much pressure (not much actually) on the individual wires breaks them at the terminal.
So, if you are the same situation, unless you can locate a better quality repair kit, which I thought I had but I know better, or just want the experience, do not bother.
