I have since found out that even more posts by other users who said they repair boards also got deleted! Incredible.
As for caps, yeah it's not just caps that I deal with obviously, as I service induction boards, it's a whole range of components, but this happens to be what I specialize in. For more average appliance techs for sure cap replacements or the odd relay etc is not a huge deal. Why wouldn't you do it if you are willing to give out a warranty period on it? (it's honestly up to the individual how they want to make their money/living)
