I'd rather repair the original one than toss it and buy a replacement.
My guess would be that the copper strands of the wire are broken. That's a high stress area and a reason they put the thicker plastic over the wire at that spot. If that's the problem, and you can get it open, then it could simply be a matter of pulling the the cord through the hole in the case, cutting the cord after the broken section, stripping the wires, and re-soldering them to their correct positions.
