Repair notes
Sessions written up as they ran: the questions, the readings with their verdicts and the path to the fix. The first one is the demo board, and says so.

Demo session
No power on the demo board: a shorted bus capacitor
Three symptom questions, a diode reading near zero on the main bus, a resistance check that confirms a hard short, and C7010 named in under two minutes. Built from a demo session on the demo board.
Real case studies follow once the first shops are running live boards; a customer’s session is only written up with their agreement and with every name and reference removed.
