Just in reference to your comment on the caps.common
mythology is once the caps blow, that's it, board is gone.
I'm not got at electronics, don't know how true that is.
Not very. It?s possible for a capacitor failure to cause collateral damage, either from
the current surge or from the mechanical forces associated with the failure. But
generally you just replace the failed part and all is well.
I remember a board with a bunch of tantalum caps that blew right off the board because the
fab shop had installed them with polarity reversed. That startled the engineer working on
board debug, but he just replaced the misinstalled parts and the board was fine.
