scrbook defines different pagestyle for special pages. For example chapter.

\newcommand*{\titlepagestyle}{plain}
\newcommand*{\partpagestyle}{plain}
\newcommand*{\chapterpagestyle}{plain}
\newcommand*{\indexpagestyle}{plain}

If only page numbers are printed at chapter pages I guess you have the command \pagestyle{empty} somewhere in your document.

Based on this guess you can use \pagestyle{headings} to set the header and footer for "normal" text pages in your document.
