Everything they've built up since then has been on their own.
The reason Protoss tech can't be easily repaired is because it so complex. Why? For the same reason that I don't expect the Terran to ever fully understand Protoss technology. Protoss live for hundreds of years, and can work far more efficiently due to their connection to others through the Khala. Their capabilities of knowledge and understanding far exceed anything a single human could gain in a few decades of life. Back to the tech, it is probably far too complex to quickly repair, unlike Terran tech, where an SCV could reattach/replace a few wires or hoses, weld a piece of sheet metal over the damaged section, and be done with it.
However, this doesn't explain why the Protoss couldn't use nanites or nano-machines to repair their equipment. Unless they're paranoid that the nanite will change their programing and seek to devour the galaxy.
