I agree that the diagnosis and visual inspection is the most important skill in fixing random items.
In the channels that I suggested, all of them go into the repair not knowing what the fault actually is. They take the viewer through the whole diagnosis, and they (with the exception of Electronics Repair School) are not electronics technicians.
Once a person has seen enough different ways of diagnosing items (by watching videos or hands on trying), then faults in other items become easier to find.
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...
