What _i'm_ missing from those videos is - while they do go through the steps finding the fault - usually don't really explain their reasoning why they suspect component a, b, c to be faulty and how exactly a good (or bad) component would behave...

Might not be the case for all the vids of course, but for those i watched i never had that "ah, that's how it works" gotcha moment...
