Circuit Diagram
In the circuit diagram, “NIU” is an abbreviation for “Not in Use,” and
“UnPop” is an abbreviation for “Unpopulated.” They both mean non-mounted
components. The circuit board and circuit board diagram show silk-screened
indications, but no components are mounted.
There are cases that the circuit diagrams are omitted. This omission will
happen to the highly integrated digital circuit boards (e.g. Main Board etc) that
are virtually impossible to repair nor analyze.
