Well I repaired electronic equipment myself (same for resolving bugs in software), and nothing is more frustrating than receiving a simple complaint "It doesn't do X or Y" without any additional info. Working on that costs huge amounts of time iterating trough all the possibilities where it could go wrong.
So what a customer should do is sending along the procedure with all the steps leading to an error, making the process reproducible. When the repairer follows the steps set on the camera he/she can quickly see where it goes wrong. This speeds up the repair enormously, the repairman will be thankful for it, and inclines towards spending more effort on the work.
