Hot bench power checks: actual fault finding or just theater?

Last week I watched a guy spend 2 hours on a bench power supply chasing a ghost signal in a Garmin GTN 650 install, when the real issue was a bad antenna cable that showed up fine on the bench but fell apart in the plane. I've seen both sides: bench testing catches board faults, but it never proves the install, so are we wasting time on shop checks or are they still worth the effort? What's your call for a shop with a 3 day turnaround on a King radio?,
