I still list a bullet point on my resume of the approximate dollar value of all the equipment I repaired myself during the ~3 years I was stationed in the calibration lab on a CVN. My favorite is the $20k precision power sensor standard that I troubleshooted down to a single transistor which cost a couple bucks to replace. I’ll add that on my ship, the “screening” you speak of was most often performed by the cal lab, since we were the only ones trained in component-level repair on general electronics. The 2M shop just did the soldering for us ;-)
