With due respect, if you are having to ask this question, then you are not
sufficiently qualified to be working on these extremely dangerous and
potentially lethal circuits. I would suggest that you first do some serious
reading-up on the principles of operation, and even more importantly, the
safety angles for working on them, before going any further with your
attempts to either work with them, or effect safe repairs. Sorry if that
appears negative, but there really are serious safety issues here.
