I have a Giant Prodigy DX. I must have snagged one of the wires, where the computer face is integrated into the handlebars, because part of the copper wires are exposed through the black cable, and I'm not getting a reading on the computer. I took it to bike repair shop, but they told me they don't do soldering there. I'm not going to get a soldering *** and try to do it myself; I would just make the problem worse and probably go blind in the process. What should I do?
