The problem is typically connector or connection related but if the computer doesn't tell them to open up the panel, disconnect then reconnect the part before determining it's defective most techs will simply order the new part. I doubt things have changed much but 10 years ago when I was setting up the systems for our parts depot (large, global telecom company) well over 90% of the parts that came back from the field tested perfect and 97.6% of these same parts that were identified by one field tech to be defective were repackaged and sent out on other service calls with no issues.
