Check 7: Is the microprocessor operating normally?
Check the conductivity of both the "Verification location 1" and the "Verification location2."
If the result is not satisfactory, check to see if there are any problems with the resin flux cored solder, parts
and components, in areas where a problem occurs, for the overall sequence of "output – input" of the checked location.
