Do you mean that you are expecting money from Google News? If so, there isn’t a system in place to earn revenue through the Publisher Center. It used to be that you could enter AdSense into your Publisher Center, but that system was discontinued because Google News sends readers to your site now, rather than rendering your articles themselves.
Or… do you mean that your site isn’t ranking on the Google News home/section/search-results pages? If that’s the case, it’s important to know that approval in the Publisher Center doesn’t qualify your site for ranking. Being approved means you get a Publication on Google News that people can subscribe to, and some control over branding options (name, logo) that Google uses on Google News and elsewhere. But it doesn’t cause your articles to rank. Ranking is done by an algorithm that is independent of the Publisher Center,
