Good story. Reminds of when I fixed a PlayStation 2 that wouldn't turn on by replacing a blown diode in its power supply. I wonder how many complex electronics are out there Sitting in landfills just a single diode away from working perfectly.
Probably most of them, even if you are experienced with electronics, with today's electronics fixing them is more of a hobby than economically viable. Something has to be worth a very large amount before it makes more sense for the regular person to seek out a professional to fix something like this.
